A sailing ship is a sea-going vessel that uses sails mounted on masts to harness the power of wind and propel the vessel. There is a variety of sail plans that propel sailing ships , employing square-rigged or fore-and-aft sails. Some ships carry square sails on each mast—the brig and full-rigged ship , said to be "ship-rigged" when there are three or more masts. Others carry only fore-and-aft sails on each mast, for instance some schooners . Still others employ a combination of square and fore-and-aft sails, including the barque , barquentine , and brigantine .
197-530: The history of the United States Navy divides into two major periods: the "Old Navy", a small but respected force of sailing ships that became notable for innovation in the use of ironclads during the American Civil War , and the "New Navy" the result of a modernization effort that began in the 1880s and made it the largest in the world by 1943. The United States Navy claims October 13, 1775 as
394-486: A conifer tree. From the 16th century, vessels were often built of a size requiring masts taller and thicker than could be made from single tree trunks. On these larger vessels, to achieve the required height, the masts were built from up to four sections (also called masts), known in order of rising height above the decks as the lower, top, topgallant and royal masts. Giving the lower sections sufficient thickness necessitated building them up from separate pieces of wood. Such
591-433: A line of battle —coordinated movements of a fleet of warships to engage a line of ships in the enemy fleet. Carracks with a single cannon deck evolved into galleons with as many as two full cannon decks, which evolved into the man-of-war, and further into the ship of the line —designed for engaging the enemy in a line of battle. One side of a ship was expected to shoot broadsides against an enemy ship at close range. In
788-519: A steering oar as a rudder to control direction. Starting in the 8th century in Denmark, Vikings were building clinker -constructed longships propelled by a single, square sail, when practical, and oars, when necessary. A related craft was the knarr , which plied the Baltic and North Seas , using primarily sail power. The windward edge of the sail was stiffened with a beitass , a pole that fitted into
985-522: A UN counter-offensive two months later. After an abortive Chinese spring offensive , UN forces retook territory roughly up to the 38th parallel. Armistice negotiations began in July 1951, but dragged on as the fighting became a war of attrition and the north suffered heavy damage from U.S. bombing . Combat ended on 27 July 1953 with the signing of the Korean Armistice Agreement , which allowed
1182-450: A destination, sailing vessels may have to change course and allow the wind to come from the opposite side in a procedure, called tacking , when the wind comes across the bow during the maneuver. When tacking, a square-rigged vessel's sails must be presented squarely to the wind and thus impede forward motion as they are swung around via the yardarms through the wind as controlled by the vessel's running rigging , using braces —adjusting
1379-530: A fast passage secured higher rates of freight or passenger fares. Whilst many clippers were ship rigged, the definition is not limited to any rig. Clippers were generally built for a specific trade: those in the California trade had to withstand the seas of Cape Horn, whilst Tea Clippers were designed for the lighter and contrary winds of the China Sea. All had fine lines, with a well streamlined hull and carried
1576-593: A fleet with 6,000 troops commanded by Lieutenant General Jean-Baptiste, comte de Rochambeau landed at Newport, Rhode Island, and shortly afterwards the fleet was blockaded by the Royal Navy. In early 1781, Washington and de Rochambeau planned an attack against the British in the Chesapeake Bay area to coordinate with the arrival of a large fleet commanded by Vice Admiral François, comte de Grasse . Successfully deceiving
1773-501: A general attack across the 38th parallel, rather than a limited operation in Ongjin. Kim was concerned that South Korean agents had learned about the plans and that South Korean forces were strengthening their defenses. Stalin agreed to this change. While these preparations were underway in the North, there were clashes along the 38th parallel, especially at Kaesong and Ongjin, many initiated by
1970-486: A general lack of money, factors for the disarmament of the navy were the loose confederation of the states, a change of goals from war to peace, and more domestic and fewer foreign interests. After the American Revolutionary War, the brand-new United States struggled to stay financially afloat. National income was desperately needed and most came from tariffs on imported goods. Because of rampant smuggling ,
2167-509: A large sail area. To get the best of this, a skilled and determined master was needed in command. During the Age of Sail, ships' hulls were under frequent attack by shipworm (which affected the structural strength of timbers), and barnacles and various marine weeds (which affected ship speed). Since before the common era, a variety of coatings had been applied to hulls to counter this effect, including pitch, wax, tar, oil, sulfur and arsenic. In

#17328631587282364-465: A load capacity of 7,800 tonnes. Ships transitioned from all sail to all steam-power from the mid 19th century into the 20th. Five-masted Preussen used steam power for driving the winches , hoists and pumps , and could be manned by a crew of 48, compared with four-masted Kruzenshtern , which has a crew of 257. Coastal top-sail schooners with a crew as small as two managing the sail handling became an efficient way to carry bulk cargo, since only
2561-433: A lower, top, and topgallant mast. Most sailing ships were merchantmen , but the Age of Sail also saw the development of large fleets of well-armed warships . The many steps of technological development of steamships during the 19th century provided slowly increasing competition for sailing ships — initially only on short routes where high prices could be charged. By the 1880s, ships with triple-expansion steam engines had
2758-579: A national political constitution on 17 July and elected Syngman Rhee as president on 20 July. The Republic of Korea (South Korea) was established on 15 August 1948. In the Soviet-Korean Zone of Occupation, the Soviets agreed to the establishment of a communist government led by Kim Il Sung. The 1948 North Korean parliamentary elections took place in August. The Soviet Union withdrew its forces in 1948 and
2955-616: A new system for training officers, and turned the old Fort Severn at Annapolis into a new institution in 1845 which would be designated as the United States Naval Academy by Congress in 1851. Naval forces participated in the effort to forcibly move the Seminole Indians from Florida to a reservation west of the Mississippi. After a massacre of army soldiers near Tampa on December 28, 1835, marines and sailors were added to
3152-501: A number of commerce raiders and blockade runners , CSS Alabama being the most famous, and British investors built small, fast blockade runners that traded arms and luxuries brought in from Bermuda , Cuba, and The Bahamas in return for high-priced cotton and tobacco. When the Union Navy seized a blockade runner, the ship and cargo were sold and the proceeds given to the Navy sailors;
3349-579: A peacetime navy for the first time, which limited the navy to six active frigates and seven in ordinary, as well as 45 officers and 150 midshipmen. The remainder of the ships in service were sold and the dismissed officers were given four months pay. The problems with the Barbary states had never gone away, and on May 10, 1801 the Tripolitans declared war on the United States by chopping down the flag in front of
3546-771: A permanent standing U.S. Navy. The original six frigates were authorized as part of the Act. Over the next 20 years, the Navy fought the French Republic Navy in the Quasi-War (1798–99), Barbary states in the First and Second Barbary Wars , and the British in the War of 1812 . After the War of 1812, the U.S. Navy was at peace until the Mexican–American War in 1846, and served to combat piracy in

Its Pacific Squadron 's ships facilitated the capture of California. In 1853, Perry led the Perry Expedition,
4137-400: A section was known as a made mast , as opposed to sections formed from single pieces of timber, which were known as pole masts . Starting in the second half of the 19th century, masts were made of iron or steel. For ships with square sails the principal masts, given their standard names in bow to stern (front to back) order, are: Each rig is configured in a sail plan , appropriate to

#17328631587284334-433: A small number of roles, such as towing sailing ships and providing short route passenger and mail services. Both sailing and steam ships saw large technological improvements over the century. Ultimately the two large stepwise improvements in fuel efficiency of compound and then triple-expansion steam engines made the steamship, by the 1880s, able to compete in the vast majority of trades. Commercial sail still continued into
4531-453: A squadron of four ships which sailed to Japan to establish normal relations with Japan. Perry's two technologically advanced steam-powered ships and calm, firm diplomacy convinced Japan to end three centuries of isolation and sign the Treaty of Kanagawa with the U.S. in 1854. Nominally a treaty of friendship, the agreement soon paved the way for the opening of Japan and normal trade relations with
4728-598: A telegram. Mao accepted the decision made by Kim and Stalin to unify Korea but cautioned Kim over possible US intervention. Soviet generals with extensive combat experience from World War II were sent to North Korea as the Soviet Advisory Group. They completed plans for attack by May and called for a skirmish to be initiated in the Ongjin Peninsula on the west coast of Korea. The North Koreans would then launch an attack to capture Seoul and encircle and destroy

While there was hesitance by some in the US government to get involved, considerations about Japan fed into the decision to engage on behalf of South Korea. After the fall of China to the communists, US experts saw Japan as the region's counterweight to the Soviet Union and China. While there
5319-512: The Chesapeake - Leopard Affair , HMS Leopard demanded that Chesapeake submit to an inspection for British deserters onboard, which was rejected. Leopard responded by opening fire on Chesapeake , and forcibly searched the ship, detaining a number of alleged British subjects. The most violent of many such encounters, the affair further fueled the tensions between the two nations and in June 1812
5516-619: The Austronesian expansion into the islands of the Indo-Pacific . This expansion originated in Taiwan c. 3000 BC and propagated through Island Southeast Asia , reaching Near Oceania c. 1500 BC, Hawaii c. 900 AD, and New Zealand c. 1200 AD. The maritime trading network in the Indo-Pacific dates from at least 1500 BC. Later developments in Asia produced
5713-536: The Barbary states , so their ships were vulnerable for capture after 1785. By 1789, the new Constitution of the United States authorized Congress to create a navy, but during George Washington's first term (1787–1793) little was done to rearm the navy. In 1793, the French Revolutionary Wars between Great Britain and France began, and a truce negotiated between Portugal and Algiers ended Portugal's blockade of
5910-631: The Borobudur temple, dating back to the 8th century CE. By the 10th century AD, the Song dynasty started building the first Chinese seafaring junks , which adopted several features of the K'un-lun po . The junk rig in particular, became associated with Chinese coast-hugging trading ships. Junks in China were constructed from teak with pegs and nails; they featured watertight compartments and acquired center-mounted tillers and rudders . These ships became
6107-495: The British Isles captured the Royal Navy frigate Serapis (1779) in the Battle of Flamborough Head . Partway through the battle, with the rigging of the two ships entangled, and several guns of Jones' ship Bonhomme Richard (1765) out of action, the captain of Serapis asked Jones if he had struck his colors , to which Jones has been quoted as replying, "I have not yet begun to fight!" France officially entered

6304-587: The Continental Congress . The resolution was introduced in the Continental Congress on October 3, 1775, but was tabled. In the meantime, George Washington had begun to acquire ships, starting with the schooner USS Hannah that was paid for out of Washington's own pocket. Hannah was commissioned and launched on September 5, 1775, under the command of Captain Nicholson Broughton , from
6501-524: The Korean and Vietnam proxy wars . Nuclear power and ballistic and guided missile technology led to new ship propulsion and weapon systems, which were used in the Nimitz -class aircraft carriers and Ohio -class submarines . By 1978, the number of ships had dwindled to less than 400, many of which were from World War II, which prompted Ronald Reagan to institute a program for a modern, 600-ship Navy . Following

Soon after, the pirates sailed into the Atlantic, and captured 11 American merchant ships and more than a hundred seamen. In reaction to the seizure of the American vessels, Congress debated and approved the Naval Act of 1794 , which authorized the building of six frigates, four of 44 guns and two of 36 guns. Supporters were mostly from

He additionally named such positions as, boatswains, gunners, carpenters, coopers, painters, tinkers, stewards, cooks and various boys as functions on
7092-654: The atomic bombing of Hiroshima . By 10 August, the Red Army had begun to occupy the north of Korea. On 10 August in Washington , US Colonels Dean Rusk and Charles H. Bonesteel III were assigned to divide Korea into Soviet and US occupation zones and proposed the 38th parallel as the dividing line. This was incorporated into the US General Order No. 1 , which responded to the Japanese surrender on 15 August. Explaining

However, commercial sailing vessels could still be found working into the 20th century, although in reducing numbers and only in certain trades. By the time of the Age of Discovery —starting in the 15th century—square-rigged, multi-masted vessels were the norm and were guided by navigation techniques that included
7486-505: The junk and dhow —vessels that incorporated features unknown in Europe at the time. European sailing ships with predominantly square rigs became prevalent during the Age of Discovery (15th to 17th centuries), when they crossed oceans between continents and around the world. In the European Age of Sail , a full-rigged ship was one with a bowsprit and three masts, each of which consists of

Use of the compass for navigation in the Indian Ocean was first mentioned in 1232. The Europeans used a "dry" compass, with a needle on a pivot. The compass card was also a European invention. At the beginning of the 15th century, the carrack was the most capable European ocean-going ship. It

The size of a ship required to carry a large number of cannon made oar-based propulsion impossible, and warships came to rely primarily on sails. The sailing man-of-war emerged during the 16th century. By the middle of the 17th century, warships were carrying increasing numbers of cannon on three decks. Naval tactics evolved to bring each ship's firepower to bear in

8274-420: The 1870s to 1900, when steamships began to outpace them economically, due to their ability to keep a schedule regardless of the wind. Steel hulls also replaced iron hulls at around the same time. Even into the twentieth century, sailing ships could hold their own on transoceanic voyages such as Australia to Europe, since they did not require bunkerage for coal nor fresh water for steam, and they were faster than

The Washington Naval Conference of 1921 recognized the Navy as equal in capital ship size to the Royal Navy, and during the 1920s and 1930s, the Navy built several aircraft carriers and battleships. The Navy was drawn into World War II after

The term "clipper" started to be used in the first quarter of the 19th century. It was applied to sailing vessels designed primarily for speed. Only a small proportion of sailing vessels could properly have the term applied to them. Early examples were

This ability was demonstrated during the First and Second Persian Gulf Wars . In March 2007,
9062-474: The 19th century. Dana described the crew of the merchant brig, Pilgrim , as comprising six to eight common sailors, four specialist crew members (the steward, cook, carpenter and sailmaker), and three officers: the captain , the first mate and the second mate . He contrasted the American crew complement with that of other nations on whose similarly sized ships the crew might number as many as 30. Larger merchant vessels had larger crews. Melville described

The invention of catamarans , outriggers , and crab claw sails enabled the Austronesian Expansion at around 3000 to 1500 BC. From Taiwan, they rapidly colonized the islands of Maritime Southeast Asia , then sailed further onwards to Micronesia , Island Melanesia , Polynesia , and Madagascar . Austronesian rigs were distinctive in that they had spars supporting both

Shortly after departing Gibraltar en route to Algiers, Decatur's squadron encountered the Algerian flagship Meshuda , and, in the Action of 17 June 1815 , captured it. Not long afterward, the American squadron likewise captured the Algerian brig Estedio in the Battle off Cape Palos . By June,

The Marines invaded the "shores of Tripoli " in 1805, capturing the city of Derna , the first time the U.S. flag ever flew over a foreign conquest. This act was enough to induce the Barbary rulers to sign peace treaties. Subsequently,
10047-452: The Americas with Christopher Columbus , and around the world under Ferdinand Magellan . Sailing ships became longer and faster over time, with ship-rigged vessels carrying taller masts with more square sails. Other sail plans emerged, as well, that had just fore-and-aft sails ( schooners ), or a mixture of the two ( brigantines , barques and barquentines ). Cannons were introduced in

Over 2,200 British merchant ships were captured by American privateers during the war, amounting to almost $ 66 million, a significant sum at the time. One particularly notable American naval officer of the Revolutionary War was John Paul Jones , who a voyage around

By spring 1950, he believed that the strategic situation had changed: PLA forces under Mao Zedong had secured final victory, US forces had withdrawn from Korea, and the Soviets had detonated their first nuclear bomb , breaking the US monopoly. As the US had not directly intervened to stop the communists in China, Stalin calculated they would be even less willing to fight in Korea, which had less strategic significance. The Soviets had cracked

The North Korean contributions to the Chinese Communist victory were not forgotten after the creation of the People's Republic of China (PRC) in 1949. As a token of gratitude, between 50,000 and 70,000 Korean veterans who served in
11032-528: The Confederacy's civilian coastal shipping. After the Civil War, most of its ships were laid up in reserve, and by 1878, the Navy was just 6,000 men. In 1882, the U.S. Navy consisted of many outdated ship designs. Over the next decade, Congress approved building multiple modern steel-hulled armored cruisers and battleships , and by around the start of the 20th century had moved from twelfth place in 1870 to fifth place in terms of numbers of ships. Most sailors were foreigners. After winning two major battles during

By the 1870s most of the ironclads from the Civil War were laid up in reserve, leaving the United States virtually without an ironclad fleet. When the Virginius Affair first broke out in 1873, a Spanish ironclad happened to be anchored in New York Harbor , leading to the uncomfortable realization on the part of the U.S. Navy that it had no ship capable of defeating such

12017-456: The Navy was greatly reduced for reasons of economy, and instead of regular ships, many gunboats were built, intended for coastal use only. This policy proved completely ineffective within a decade. President Thomas Jefferson and his Democratic-Republican party opposed a strong navy, arguing that the small gunboats stationed in the major Atlantic harbors, part of first Secretary of the Treasury Alexander Hamilton's U.S. Revenue-Marine , were all

In five days, the ROK, which had 95,000 troops on 25 June, was down to less than 22,000 troops. In early July, when US forces arrived, what was left of the ROK was placed under US operational command of the United Nations Command . The Truman administration was unprepared for the invasion. Korea

China promised to support the North Koreans in the event of a war against South Korea. By 1948, a North Korea-backed insurgency had broken out in the southern half of the peninsula. This was exacerbated by the undeclared border war between the Koreas, which saw division-level engagements and thousands of deaths on both sides. The ROK

Large U.S. garrisons and air forces were in Japan, but only 200–300 U.S. troops were in Korea. At dawn on 25 June 1950, the KPA crossed the 38th parallel behind artillery fire. It justified its assault with

On 7 June 1950, Kim called for a Korea-wide election on 5–8 August 1950 and a consultative conference in Haeju on 15–17 June. On 11 June, the North sent three diplomats to the South as a peace overture, which Rhee rejected outright. On 21 June, Kim revised his war plan to involve

This operation crippled the insurgency. Soon after, North Korea made final attempts to keep the uprising active, sending battalion-sized units of infiltrators under the commands of Kim Sang-ho and Kim Moo-hyon. The first battalion

American merchant shipping had been protected by the Royal Navy during the colonial era, but as a consequence of the Treaty of Paris and the disarmament of the Continental Navy, the United States no longer had any protection for its ships from pirates. The fledgling nation did not have the funds to pay annual tribute to

The United States preferred to take a position of neutrality in the conflicts between France and Britain, but this put the nation at odds with both the British and French. After the Jay Treaty was signed with Great Britain in 1794, France began to side against the United States and by 1797 they had seized over 300 American vessels. The newly inaugurated President John Adams took steps to deal with
13790-426: The South Korean interior intensified; persistent operations, paired with worsening weather, denied the guerrillas sanctuary and wore away their fighting strength. North Korea responded by sending more troops to link up with insurgents and build more partisan cadres; North Korean infiltrators had reached 3,000 soldiers in 12 units by the start of 1950, but all were destroyed or scattered by the ROKA.

However, Kim Il Sung believed widespread uprisings had weakened the South Korean military and that a North Korean invasion would be welcomed by much of the South Korean population. Kim began seeking Stalin's support for an invasion in March 1949, traveling to Moscow to persuade him. Stalin initially did not think the time was right for a war in Korea. PLA forces were still embroiled in

While older histories of the conflict often referred to these ethnic Korean PLA veterans as being sent from northern Korea to fight in the Chinese Civil War before being sent back, recent Chinese archival sources studied by Kim Donggill indicate that this
14578-739: The South. The ROK was being trained by the US Korean Military Advisory Group (KMAG). On the eve of the war, KMAG commander General William Lynn Roberts voiced utmost confidence in the ROK and boasted that any North Korean invasion would merely provide "target practice". For his part, Syngman Rhee repeatedly expressed his desire to conquer the North, including when US diplomat John Foster Dulles visited Korea on 18 June. Though some South Korean and US intelligence officers predicted an attack, similar predictions had been made before and nothing had happened. The Central Intelligence Agency noted
14775-720: The Soviet Union would not move against US forces in Korea. The Truman administration believed it could intervene in Korea without undermining its commitments elsewhere. On 25 June 1950, the United Nations Security Council unanimously condemned the North Korean invasion of South Korea with Resolution 82 . The Soviet Union, a veto-wielding power , had boycotted Council meetings since January 1950, protesting Taiwan 's occupation of China's permanent seat . The Security Council, on 27 June 1950, published Resolution 83 recommending member states provide military assistance to
14972-461: The U.S. Navy became visible after the Somers Affair , an alleged mutiny aboard the training ship USS Somers in 1842, and the subsequent execution of midshipman Philip Spencer . George Bancroft , appointed Secretary of the Navy in 1845, decided to work outside of congressional approval and create a new academy for officers. He formed a council led by Commodore Matthew Perry to create
15169-508: The U.S. Navy reached its smallest fleet size, with 274 ships, since World War I. Former U.S. Navy admirals who head the U.S. Naval Institute have raised concerns about what they see as the ability to respond to 'aggressive moves by Iran and China.' The United States Navy was overtaken by the Chinese People's Liberation Army Navy in terms of raw number of ships in 2020. Resolved , That a swift sailing vessel, to carry ten carriage guns, and
15366-429: The U.S. Navy the second largest in the world after the Royal Navy. By 1880 the Navy only had 48 ships in commission, 6,000 men, and the ships and shore facilities were decrepit but Congress saw no need to spend money to improve them. The Navy was unprepared to fight a major maritime war before 1897. In 1871, an expedition of five warships commanded by Rear Admiral John Rodgers was sent to Korea to obtain an apology for
15563-439: The U.S. declared war on Britain. Much of the war was expected to be fought at sea; and within an hour of the announcement of war, the diminutive U.S. Navy set forth to do battle with an opponent outnumbering it 50-to-1. After two months, Constitution sank HMS Guerriere ; Guerriere ' s crew were most dismayed to see their cannonballs bouncing off Constitution ' s unusually strong live oak hull, giving her
15760-741: The UK, and the US decided that "in due course, Korea shall become free and independent". At the Tehran Conference in 1943 and the Yalta Conference in February 1945, the Soviet Union promised to join its allies in the Pacific War within three months of the victory in Europe . Germany officially surrendered on 8 May 1945, and the USSR declared war on Japan and invaded Manchuria on 8 August 1945, two days after
15957-713: The US in 1949. With the end of the war with Japan , the Chinese Civil War resumed in earnest between the Communists and the Nationalist -led government. While the Communists were struggling for supremacy in Manchuria, they were supported by the North Korean government with matériel and manpower. According to Chinese sources, the North Koreans donated 2,000 railway cars worth of supplies while thousands of Koreans served in
16154-615: The USAMGIK declared martial law . Citing the inability of the Joint Commission to make progress, the US government decided to hold an election under UN auspices to create an independent Korea. The Soviet authorities and Korean communists refused to cooperate on the grounds it would not be fair, and many South Korean politicians boycotted it. The 1948 South Korean general election was held in May. The resultant South Korean government promulgated
16351-631: The United Kingdom and China after the East India Company lost its monopoly in 1834. The primary cargo was tea, and sailing ships, particularly tea clippers, dominated this long distance route until the development of fuel efficient steamships coincided with the opening of the Suez Canal in 1869. Other clippers worked on the Australian immigrant routes or, in smaller quantities, in any role where
16548-567: The United States Navy captured only 10 slave vessels, while the British captured 423 vessels carrying 27,000 captives. Congress formally authorized the establishment of the United States Military Academy in 1802, but it took almost 50 years to approve a similar school for naval officers. During the long period of peace between 1815 and 1846, midshipmen had few opportunities for promotion, and their warrants were often obtained via patronage. The poor quality of officer training in
16745-675: The United States and Europe. Between the beginning of the war and the end of 1861, 373 commissioned officers, warrant officers, and midshipmen resigned or were dismissed from the United States Navy and went on to serve the Confederacy. On April 20, 1861, the Union burned its ships that were at the Norfolk Navy Yard to prevent their capture by the Confederates , but not all of the ships were completely destroyed. The screw frigate USS Merrimack
16942-420: The area to that end. The Truman administration still refrained from committing troops on the ground, because advisers believed the North Koreans could be stopped by air and naval power alone. The Truman administration was uncertain whether the attack was a ploy by the Soviet Union, or just a test of US resolve. The decision to commit ground troops became viable when a communiqué was received on 27 June indicating
17139-479: The area". As Rusk's comments indicate, the US doubted whether the Soviets would agree. Joseph Stalin , however, maintained his wartime policy of cooperation, and on 16 August, the Red Army halted at the 38th parallel for three weeks to await the arrival of US forces. On 7 September 1945, General Douglas MacArthur issued Proclamation No. 1 to the people of Korea, announcing US military control over Korea south of
17336-471: The basis for the development of Chinese warships during the Mongol Yuan dynasty , and were used in the unsuccessful Mongol invasions of Japan and Java . The Ming dynasty (1368–1644) saw the use of junks as long-distance trading vessels. Chinese Admiral Zheng He reportedly sailed to India, Arabia, and southern Africa on a trade and diplomatic mission. Literary lore suggests that his largest vessel,
17533-501: The battle managed to slow down the progression of British ground forces in New York. By mid-1776, a number of ships, ranging up to and including the thirteen frigates approved by Congress, were under construction, but their effectiveness was limited; they were completely outmatched by the Royal Navy, and nearly all were captured or sunk by 1781. American privateers had some success, with 1,697 letters of marque being issued by Congress. Individual states, American agents in Europe and in
17730-574: The beginning of the war, devised the Anaconda Plan to win the war with as little bloodshed as possible. His idea was that a Union blockade of the main ports would weaken the Confederate economy; then the capture of the Mississippi River would split the South. Lincoln adopted the plan in terms of a blockade to squeeze to death the Confederate economy, but overruled Scott's warnings that his new army
17927-470: The border, starting in May 1949. Border clashes between South and North continued on 4 August 1949, when thousands of North Korean troops attacked South Korean troops occupying territory north of the 38th parallel. The 2nd and 18th ROK Infantry Regiments repulsed attacks in Kuksa-bong, and KPA troops were "completely routed". Border incidents decreased by the start of 1950. Meanwhile, counterinsurgencies in
18124-767: The border, these guerrillas launched an offensive in September aimed at undermining the South Korean government and preparing the country for the KPA's arrival in force. This offensive failed. However, the guerrillas were now entrenched in the Taebaek-san region of the North Gyeongsang Province and the border areas of the Gangwon Province . While the insurgency was ongoing, the ROKA and KPA engaged in battalion-sized battles along
18321-404: The bow. By the nineteenth century, ships were built with reference to a half model, made from wooden layers that were pinned together. Each layer could be scaled to the actual size of the vessel in order to lay out its hull structure, starting with the keel and leading to the ship's ribs. The ribs were pieced together from curved elements, called futtocks and tied in place until the installation of
18518-411: The building of thirteen frigates within the next three months, five ships of 32 guns, five with 28 guns and three with 24 guns. On Lake Champlain, Benedict Arnold ordered the construction of 12 naval vessels to slow down the progress of British forces which had entered New York from Canada. In the ensuing engagement , a Royal Navy fleet decisively defeated Arnold's ships after two days of fighting, but
18715-492: The captured crewmen were mostly British and they were simply released. The blockade of the South caused the Southern economy to collapse during the war. Shortages of food and supplies were caused by the blockade, the failure of Southern railroads, the loss of control of the main rivers, and foraging by Union and Confederate armies. The standard of living fell even as large-scale printing of paper money caused inflation and distrust of
18912-487: The choice of the 38th parallel, Rusk observed, "Even though it was further north than could be realistically reached by U. S. [ sic ] forces in the event of Soviet disagreement ... we felt it important to include the capital of Korea in the area of responsibility of American troops". He noted that he was "faced with the scarcity of U.S. forces immediately available and time and space factors which would make it difficult to reach very far north before Soviet troops could enter
19109-542: The claim ROK troops attacked first and that the KPA were aiming to arrest and execute the "bandit traitor Syngman Rhee". Fighting began on the strategic Ongjin Peninsula in the west. There were initial South Korean claims that the 17th Regiment had counterattacked at Haeju; some scholars argue the claimed counterattack was instead the instigating attack, and therefore that the South Koreans may have fired first. However,
19306-509: The clew of a square sail forward. The crew of a sailing ship is divided between officers (the captain and his subordinates) and seamen or ordinary hands . An able seaman was expected to "hand, reef, and steer" (handle the lines and other equipment, reef the sails, and steer the vessel). The crew is organized to stand watch —the oversight of the ship for a period—typically four hours each. Richard Henry Dana Jr. and Herman Melville each had personal experience aboard sailing vessels of
19503-575: The codes used by the US to communicate with their embassy in Moscow , and reading dispatches convinced Stalin that Korea did not have the importance to the US that would warrant a nuclear confrontation. Stalin began a more aggressive strategy in Asia based on these developments, including promising economic and military aid to China through the Sino-Soviet Treaty of Friendship, Alliance and Mutual Assistance . In April 1950, Stalin permitted Kim to attack
19700-488: The command of Sir James Hillyar , blockaded Essex before Porter ordered his ship to attempt to escape; in the ensuing battle , Essex was captured by the British. The capture of the three Royal Navy frigates led the British to deploy more vessels on the American seaboard to tighten their blockade of U.S. ports. On June 1, 1813, off Boston Harbor , the American frigate Chesapeake , commanded by Captain James Lawrence ,
19897-458: The communist victory in the Chinese Civil War, ethnic Korean units in the PLA were sent to North Korea. In the fall of 1949, two PLA divisions composed mainly of Korean-Chinese troops (the 164th and 166th ) entered North Korea, followed by smaller units throughout the rest of 1949. The reinforcement of the KPA with PLA veterans continued into 1950, with the 156th Division and several other units of
20094-454: The construction of many new ships. However, the expense of the larger ships was prohibitive, and many of them stayed in shipyards half-completed, in readiness for another war, until the Age of Sail had almost completely passed. The main force of the Navy continued to be large sailing frigates with a number of smaller sloops during the three decades of peace. By the 1840s, the Navy began to adopt steam power and shell guns, but they lagged behind
20291-516: The country. The Provisional Government of the Republic of Korea was founded in 1919 in Nationalist China . It failed to achieve international recognition, failed to unite the nationalist groups, and had a fractious relationship with its US-based founding president, Syngman Rhee . From 1919 to 1925 and beyond, Korean communists led internal and external warfare against the Japanese. In China,
20488-421: The crew complement of the frigate warship, United States , as about 500—including officers, enlisted personnel and 50 Marines. The crew was divided into the starboard and larboard watches. It was also divided into three tops , bands of crew responsible for setting sails on the three masts; a band of sheet-anchor men , whose station was forward and whose job was to tend the fore-yard, anchors and forward sails;
20685-475: The crisis, working with Congress to finish the three almost-completed frigates, approving funds to build the other three, and attempting to negotiate an agreement similar to the Jay Treaty with France. The XYZ Affair originated with a report distributed by Adams where alleged French agents were identified by the letters X, Y, and Z who informed the delegation a bribe must be paid before the diplomats could meet with
20882-619: The currency. By 1864 the internal food distribution had broken down, leaving cities without enough food and causing food riots across the Confederacy. The Union victory at the Second Battle of Fort Fisher in January 1865 closed the last useful Southern port, virtually ending blockade running and hastening the end of the war. After the war, the Navy went into a period of decline. In 1864, the Navy had 51,500 men in uniform, and almost 700 ships and about 60 monitor-type coastal ironclads which made
21079-617: The date of its commencement on 25 June. In North Korea, the war is officially referred to as the Fatherland Liberation War ( Choguk haebang chŏnjaeng ) or the " Chosŏn [Korean] War" ( 조선전쟁 ; Chosŏn chŏnjaeng ). In mainland China, the segment of the war after the intervention of the People's Volunteer Army is commonly and officially known as the "Resisting America and Assisting Korea War" ( Chinese : 抗美援朝战争 ; pinyin : Kàngměi Yuáncháo Zhànzhēng ), although
21276-733: The date of its official establishment, when the Second Continental Congress passed a resolution creating the Continental Navy . With the end of the American Revolutionary War , the Continental Navy was disbanded. Under the Presidency of George Washington , merchant shipping came under threat while in the Mediterranean by Barbary pirates from four North African States. This led to the Naval Act of 1794 , which created
21473-563: The defense of Italy and Greece, and the country was first on the list of the National Security Council 's post-North Korea invasion list of "chief danger spots". Truman believed if aggression went unchecked, a chain reaction would start that would marginalize the UN and encourage communist aggression elsewhere. The UN Security Council approved the use of force to help the South Koreans, and the US immediately began using air and naval forces in
21670-611: The early 19th century, until the advent of iron and steel hulls. Iron-hulled sailing ships , often referred to as " windjammers " or " tall ships ", represented the final evolution of sailing ships at the end of the Age of Sail. They were built to carry bulk cargo for long distances in the nineteenth and early twentieth centuries. They were the largest of merchant sailing ships, with three to five masts and square sails, as well as other sail plans . They carried lumber , guano , grain or ore between continents. Later examples had steel hulls. Iron-hulled sailing ships were mainly built from
21867-421: The early steamers, which usually could barely make 8 knots (15 km/h). The four-masted, iron-hulled ship, introduced in 1875 with the full-rigged County of Peebles , represented an especially efficient configuration that prolonged the competitiveness of sail against steam in the later part of the 19th century. The largest example of such ships was the five-masted, full-rigged ship Preussen , which had
22064-509: The economic and military aid promised by the Soviets. Kathryn Weathersby cites Soviet documents which said Kim secured Mao's support. Along with Mark O'Neill, she says this accelerated Kim's war preparations. Chen Jian argues Mao never seriously challenged Kim's plans and Kim had every reason to inform Stalin that he had obtained Mao's support. Citing more recent scholarship, Zhao Suisheng contends Mao did not approve of Kim's war proposal and requested verification from Stalin, who did so via
22261-551: The end of World War II in 1945, Korea, which had been a Japanese colony for 35 years, was divided by the Soviet Union and the US into two occupation zones at the 38th parallel , with plans for a future independent state. Due to political disagreements and influence from their backers, the zones formed their own governments in 1948. The DPRK was led by Kim Il Sung in Pyongyang , and the ROK by Syngman Rhee in Seoul ; both claimed to be
22458-483: The enduring nickname of "Old Ironsides". On December 29, 1812 Constitution defeated HMS Java off the coast of Brazil and Java was burned after the Americans determined she could not be salvaged. On October 25, 1812, United States captured HMS Macedonian ; after the battle Macedonian was captured and entered into American service. In 1813, USS Essex commenced a very fruitful raiding venture into
22655-543: The exchange of prisoners and created a 4-kilometre (2.5 mi) wide Demilitarized Zone (DMZ) along the frontline, with a Joint Security Area at Panmunjom . The conflict caused more than 1 million military deaths and an estimated 2 to 3 million civilian deaths, a larger proportion of civilian deaths than in World War II or the Vietnam War . Alleged war crimes include the mass killing of suspected communists by Seoul and
22852-412: The expence, and lay the same before the Congress, and to contract with proper persons to fit out the vessel. Resolved , that another vessel be fitted out for the same purposes, and that the said committee report their opinion of a proper vessel, and also an estimate of the expence. Resolution of the Continental Congress that marked the establishment of what is now the United States Navy. The Navy
23049-454: The first steam-powered ship to see combat action. Although isolated instances of piracy continued into the 1830s, by 1826 the frequent attacks had ended and the region was declared free for commerce. Another international problem was the slave trade, and the African squadron was formed in 1820 to deal with this threat. Politically, the suppression of the slave trade was unpopular, and the squadron
23246-482: The fleet from entering the harbor; the army reembarked on the ships, ending the battle. The American naval victories at the Battle of Lake Champlain and Battle of Lake Erie halted the final British offensive in the north and helped to deny the British exclusive rights to the Great Lakes in the Treaty of Ghent . Shortly before the treaty was signed, President was captured by four British frigates. Three days after
23443-611: The forces which fought the Second Seminole War from 1836 until 1842. A "mosquito fleet" was formed in the Everglades out of various small craft to transport a mixture of army and navy personnel to pursue the Seminoles into the swamps. About 1,500 soldiers were killed during the conflict, some Seminoles agreed to move but a small group of Seminoles remained in control of the Everglades and the area around Lake Okeechobee. The Navy played
23640-419: The fore and aft angle of each yardarm around the mast—and sheets attached to the clews (bottom corners) of each sail to control the sail's angle to the wind. The procedure is to turn the vessel into the wind with the hind-most fore-and-aft sail (the spanker ), pulled to windward to help turn the ship through the eye of the wind. Once the ship has come about, all the sails are adjusted to align properly with
23837-562: The fore-sails required tending while tacking and steam-driven machinery was often available for raising the sails and the anchor . In the 20th century, the DynaRig allowed central, automated control of all sails in a manner that obviates the need for sending crew aloft. This was developed in the 1960s in Germany as a low-carbon footprint propulsion alternative for commercial ships. The rig automatically sets and reefs sails; its mast rotates to align
24034-524: The foreign minister, and the resulting scandal increased popular support in the country for a war with France. Concerns about the War Department's ability to manage a navy led to the creation of the Department of the Navy , which was established on April 30, 1798. The war with France was fought almost entirely at sea, mostly between privateers and merchant ships. The first victory for the United States Navy
24231-459: The former Fourth Field Army arriving in February; the PLA 156th Division was reorganized as the KPA 7th Division. By mid-1950, between 50,000 and 70,000 former PLA troops had entered North Korea, forming a significant part of the KPA's strength on the eve of the war's beginning. The combat veterans and equipment from China, the tanks, artillery, and aircraft supplied by the Soviets, and rigorous training increased North Korea's military superiority over
24428-472: The government and between 2,976 and 3,392 deaths. By May 1949, both uprisings had been crushed. Insurgency reignited in the spring of 1949 when attacks by guerrillas in the mountainous regions (buttressed by army defectors and North Korean agents) increased. Insurgent activity peaked in late 1949 as the ROKA engaged so-called People's Guerrilla Units. Organized and armed by the North Korean government, and backed by 2,400 KPA commandos who had infiltrated through
24625-576: The government in the South, under the condition that Mao would agree to send reinforcements if needed. For Kim, this was the fulfillment of his goal to unite Korea. Stalin made it clear Soviet forces would not openly engage in combat, to avoid a direct war with the US Kim met with Mao in May 1950 and differing historical interpretations of the meeting have been put forward. According to Barbara Barnouin and Yu Changgeng, Mao agreed to support Kim despite concerns of American intervention, as China desperately needed
24822-618: The government. At 02:00 on 28 June the ROK blew up the Hangang Bridge across the Han River in an attempt to stop the KPA. The bridge was detonated while 4,000 refugees were crossing it, and hundreds were killed. Destroying the bridge trapped many ROK units north of the river. In spite of such desperate measures, Seoul fell that same day. Some South Korean National Assemblymen remained in Seoul when it fell, and 48 subsequently pledged allegiance to
25019-426: The implementation of center-mounted rudders, controlled with a tiller. Technological advancements that were important to the Age of Discovery in the 15th century were the adoption of the magnetic compass and advances in ship design. The compass was an addition to the ancient method of navigation based on sightings of the sun and stars. The compass was invented by Chinese. It had been used for navigation in China by
25216-749: The influence of China over Korea in the First Sino-Japanese War (1894–95), ushering in the short-lived Korean Empire . A decade later, after defeating Imperial Russia in the Russo-Japanese War , Japan made the Korean Empire its protectorate with the Eulsa Treaty in 1905, then annexed it with the Japan–Korea Treaty of 1910 . The Korean Empire fell, and Korea was directly ruled by Japan between 1910–45. Many Korean nationalists fled
25413-799: The insurgent war and border clashes. The first socialist uprising occurred without direct North Korean participation, though the guerrillas still professed support for the northern government. Beginning in April 1948 on Jeju Island , the campaign saw arrests and repression by the South Korean government in the fight against the South Korean Labor Party, resulting in 30,000 violent deaths, among them 14,373 civilians, of whom ~2,000 were killed by rebels and ~12,000 by ROK security forces. The Yeosu–Suncheon rebellion overlapped with it, as several thousand army defectors waving red flags massacred right-leaning families. This resulted in another brutal suppression by
25610-493: The invasion force, the North had 114 fighters, 78 bombers, 105 T-34-85 tanks, and some 30,000 soldiers stationed in reserve in North Korea. Although each navy consisted of only several small warships, the North and South Korean navies fought in the war as seaborne artillery for their armies. In contrast, the South Korean population was estimated at 20 million, but its army was unprepared and ill-equipped. As of 25 June 1950,
25807-534: The invasion. UN forces comprised 21 countries, with the US providing around 90% of military personnel. Seoul was captured on 28 June, and by early August, the Republic of Korea Army (ROKA) and its allies were nearly defeated, holding onto only the Pusan Perimeter in the peninsula's southeast. On 15 September, UN forces landed at Inchon near Seoul, cutting off KPA troops and supply lines. UN forces broke out from
26004-468: The large-diameter line run around them, whilst multiple holes allowed smaller line— lanyard —to pass multiple times between the two and thereby allow tensioning of the shroud. After the mid-19th century square-rigged vessels were equipped with iron wire standing rigging, which was superseded with steel wire in the late 19th century. Halyards , used to raise and lower the yards, are the primary supporting lines. In addition, square rigs have lines that lift
26201-525: The lower corner of the sail, when sailing close to the wind. India's maritime history began during the 3rd millennium BCE when inhabitants of the Indus Valley initiated maritime trading contact with Mesopotamia. Indian kingdoms such as the Kalinga from as early as 2nd century CE are believed to have had sailing ships. One of the earliest instances of documented evidence of Indian sailing ship building comes from
26398-402: The magnetic compass and making sightings of the sun and stars that allowed transoceanic voyages. The Age of Sail reached its peak in the 18th and 19th centuries with large, heavily armed battleships and merchant sailing ships . Sailing and steam ships coexisted for much of the 19th century. The steamers of the early part of the century had very poor fuel efficiency and were suitable only for
26595-401: The man-of-war. 18-19th century ships of the line had a complement as high as 850. Handling a sailing ship requires management of its sails to power—but not overpower—the ship and navigation to guide the ship, both at sea and in and out of harbors. Key elements of sailing a ship are setting the right amount of sail to generate maximum power without endangering the ship, adjusting the sails to
26792-596: The mast became a single pole, and paddles were supplanted with oars. Such vessels plied both the Nile and the Mediterranean coast. The Minoan civilization of Crete may have been the world's first thalassocracy brought to prominence by sailing vessels dating to before 1800 BC (Middle Minoan IIB). Between 1000 BC and 400 AD, the Phoenicians , Greeks and Romans developed ships that were powered by square sails, sometimes with oars to supplement their capabilities. Such vessels used
26989-399: The mid 18th century copper sheathing was developed as a defense against such bottom fouling. After coping with problems of galvanic deterioration of metal hull fasteners, sacrificial anodes were developed, which were designed to corrode, instead of the hull fasteners. The practice became widespread on naval vessels, starting in the late 18th century, and on merchant vessels, starting in
27186-527: The most famous of the six, was nicknamed "Old Ironsides" (like the earlier HMS Britannia ) and, thanks to the efforts of Oliver Wendell Holmes Sr. , is still in existence today, anchored in Boston harbor. Soon after the bill was passed, Congress authorized $ 800,000 to obtain a treaty with the Algerians and ransom the captives, triggering an amendment of the Act which would halt the construction of ships if peace
27383-538: The mural of three-masted ship in the Ajanta caves that date back to 400-500 CE. The Indian Ocean was the venue for increasing trade between India and Africa between 1200 and 1500. The vessels employed would be classified as dhows with lateen rigs . During this interval such vessels grew in capacity from 100 to 400 tonnes . Dhows were often built with teak planks from India and Southeast Asia, sewn together with coconut husk fiber—no nails were employed. This period also saw
27580-471: The murders of several shipwrecked American sailors and secure a treaty to protect shipwrecked foreigners in the future. After a small skirmish, Rodgers launched an amphibious assault of approximately 650 men on the forts protecting Seoul. Despite the capture of the forts, the Koreans refused to negotiate, and the expedition was forced to leave before the start of typhoon season. Nine sailors and six marines received Medals of Honor for their acts of heroism during
27777-493: The nation needed to defend itself. However, this small fleet of lightly armed revenue cutters , which Hamilton had proposed in Federalist Papers No. 11 & 12, was insufficient as a wartime naval force for the needs of the new United States of America. During the French Revolutionary Wars, the Royal Navy had begun to impress sailors from American ships who they alleged were British deserters; an estimated 10,000 sailors were impressed this way between 1799 and 1812. In 1807, in
27974-436: The nationalist National Revolutionary Army and the communist People's Liberation Army (PLA) helped organize Korean refugees against the Japanese military, which had also occupied parts of China. The Nationalist-backed Koreans, led by Yi Pom-Sok , fought in the Burma campaign (1941-45). The communists, led by, among others, Kim Il Sung , fought the Japanese in Korea and Manchuria . At the Cairo Conference in 1943, China,
28171-403: The need was immediate for strong enforcement of tariff laws. On August 4, 1790, the United States Congress , urged on by Secretary of the Treasury Alexander Hamilton , created the Revenue-Marine , the forerunner for the United States Coast Guard , to enforce the tariff and all other maritime laws. Ten cutters were initially ordered. Between 1790 and 1797 when the Navy Department was created,
28368-418: The new tack. Because square-rigger masts are more strongly braced from behind than from ahead, tacking is a dangerous procedure in strong winds; the ship may lose forward momentum (become caught in stays ) and the rigging may fail from the wind coming from ahead. The ship may also lose momentum at wind speeds of less than 10 knots (19 km/h). Under these conditions, the choice may be to wear ship —to turn
28565-525: The northern states and the coastal regions, who argued the Navy would result in savings in insurance and ransom payments, while opponents from southern states and inland regions thought a navy was not worth the expense and would drive the United States into more costly wars. After the passage of the Naval Act of 1794, work began on the construction of the six frigates: USS United States , President , Constellation , Chesapeake , Congress , and Constitution . Constitution , launched in 1797 and
28762-406: The operation was conducted under the auspices of the UN. It has been sometimes referred to in the English-speaking world as "The Forgotten War" or "The Unknown War" because of the lack of public attention it received during and afterward, relative to the global scale of World War II, which preceded it, and the subsequent angst of the Vietnam War , which succeeded it. Imperial Japan diminished
28959-498: The other to form the whole, from bottom to top: the lower mast , top mast , and topgallant mast . This construction relied heavily on support by a complex array of stays and shrouds. Each stay in either the fore-and-aft or athwartships direction had a corresponding one in the opposite direction providing counter-tension. Fore-and-aft the system of tensioning started with the stays that were anchored in front each mast. Shrouds were tensioned by pairs of deadeyes , circular blocks that had
29156-472: The perimeter on 18 September, re-captured Seoul, and invaded North Korea in October, capturing Pyongyang and advancing towards the Yalu River —the border with China. On 19 October, the Chinese People's Volunteer Army (PVA) crossed the Yalu and entered the war on the side of the north. UN forces retreated from North Korea in December, following the PVA's first and second offensive . Communist forces captured Seoul again in January 1951 before losing it to
29353-544: The pirates were privateers of the newly independent states of Latin America, he decided to embark on a strategy of diplomacy backed up by the guns of the Navy. An agreement with Venezuela was reached in 1819, but ships were still regularly captured until a military campaign by the West India Squadron, under the command of David Porter , used a combination of large frigates escorting merchant ships backed by many small craft searching small coves and islands, and capturing pirate vessels. During this campaign USS Sea Gull became
29550-407: The planking. Typically, planking was caulked with a tar-impregnated yarn made from manila or hemp to make the planking watertight. Starting in the mid-19th century, iron was used first for the hull structure and later for its watertight sheathing. Until the mid-19th century all vessels' masts were made of wood formed from a single or several pieces of timber which typically consisted of the trunk of
29747-437: The port of Marblehead, Massachusetts . The US Navy recognizes October 13, 1775, as the date of its official establishment—the date of the passage of the resolution of the Continental Congress at Philadelphia, Pennsylvania, that created the Continental Navy. On this day, Congress authorized the purchase of two vessels to be armed for a privateering cruise against British merchant shipping. On December 13, 1775, Congress authorized
29944-442: The report that contained the Haeju claim contained errors and outright falsehoods. KPA forces attacked all along the 38th parallel within an hour. The KPA had a combined arms force including tanks supported by heavy artillery. The ROK had no tanks, anti-tank weapons, or heavy artillery. The South Koreans committed their forces in a piecemeal fashion, and these were routed in a few days. On 27 June, Rhee evacuated Seoul with some of
30141-410: The resulting geyser of water put out the fires in the submarine's boiler, rendering the submarine immobile. Another submarine, CSS H.L. Hunley , was designed to dive and surface but ultimately did not work well and sank on five occasions during trials. In action against USS Housatonic the submarine successfully sank its target but was lost by the same explosion. The Confederates operated
30338-427: The sail or the yard from which it is suspended that include: brails , buntlines , lifts and leechlines. Bowlines and clew lines shape a square sail. To adjust the angle of the sail to wind braces are used to adjust the fore and aft angle of a yard of a square sail, while sheets attach to the clews (bottom corners) of a sail to control the sail's angle to the wind. Sheets run aft, whereas tacks are used to haul
30535-560: The sail to draw wind. Mainsails are often self-tending and slide on a traveler to the opposite side. On certain rigs, such as lateens and luggers , the sail may be partially lowered to bring it to the opposite side. Korean War Korean Demilitarized Zone established Together: 1,742,000 The Korean War (25 June 1950 – 27 July 1953) was an armed conflict on the Korean Peninsula fought between North Korea (Democratic People's Republic of Korea; DPRK) and South Korea (Republic of Korea; ROK) and their allies. North Korea
30732-410: The sail up and secure it with lines, called reef points . Dana spoke of the hardships of sail handling during high wind and rain or with ice covering the ship and its rigging. Sailing vessels cannot sail directly into the wind. Instead, square-riggers must sail a course that is between 60° and 70° away from the wind direction and fore-and aft vessels can typically sail no closer than 45°. To reach
30929-430: The sail, the crew uses clewlines , haul up the clews and buntlines to haul up the middle of sail up; when lowered, lifts support each yard. In strong winds, the crew is directed to reduce the number of sails or, alternatively, the amount of each given sail that is presented to the wind by a process called reefing . To pull the sail up, seamen on the yardarm pull on reef tackles , attached to reef cringles , to pull
31126-441: The sails with the wind. The sailing yachts Maltese Falcon and Black Pearl employ the rig. In the 21st century, due to concern about climate change and the possibility of cost savings, companies explored using wind-power to reduce heavy fuel needs on large containerized cargo ships . By 2023, around 30 ships were using sails or attached kites, with the number expected to grow. The following year, The Economist wrote that
31323-491: The schooners and brigantines, called Baltimore clippers , used for blockade running or as privateers in the War of 1812 and afterwards for smuggling opium or illegally transporting slaves . Larger clippers, usually ship or barque rigged and with a different hull design, were built for the California trade (from east coast USA ports to San Francisco) after gold was discovered in 1848 – the associated ship-building boom lasted until 1854. Clippers were built for trade between
31520-415: The ship away from the wind and around 240° onto the next tack (60° off the wind). A fore-and-aft rig permits the wind to flow past the sail, as the craft head through the eye of the wind. Most rigs pivot around a stay or the mast, while this occurs. For a jib , the old leeward sheet is released as the craft heads through the wind and the old windward sheet is tightened as the new leeward sheet to allow
31717-432: The size of the sailing craft. Both square-rigged and fore-and-aft rigged vessels have been built with a wide range of configurations for single and multiple masts. Types of sail that can be part of a sail plan can be broadly classed by how they are attached to the sailing craft: Sailing ships have standing rigging to support the masts and running rigging to raise the sails and control their ability to draw power from
31914-413: The sloop Katy , and commodore of the armed vessels employed by the government. The first formal movement for the creation of the Continental Navy came from Rhode Island, because the widespread smuggling activities of Rhode Island merchants had been increasing suppressed by the British Royal Navy . On August 26, 1775, Rhode Island passed a resolution that there be a single Continental fleet funded by
32111-411: The sole legitimate government of all of Korea and engaged in border clashes as internal unrest was fomented by communist groups in the south. On 25 June 1950, the Korean People's Army (KPA), equipped and trained by the Soviets, launched an invasion of the south. In the absence of the Soviet Union's representative, the UN Security Council denounced the attack and recommended member states to repel
32308-444: The southward movement by the KPA but assessed this as a "defensive measure" and concluded an invasion was "unlikely". On 23 June UN observers inspected the border and did not detect that war was imminent. Chinese involvement was extensive from the beginning, building on previous collaboration between the Chinese and Korean communists during the Chinese Civil War. Throughout 1949 and 1950, the Soviets continued arming North Korea. After
32505-421: The squadrons had reached Algiers and peace was negotiated with the Dey, including a return of captured vessels and men, a guarantee of no further tributes and a right to trade in the region. Piracy in the Caribbean sea was also a major problem, and between 1815 and 1822 an estimated 3,000 ships were captured by pirates. In 1819, Congress authorized President James Madison to deal with this threat, and since many of
32702-530: The technology was at an inflection point as it moved from trials and testing towards adoption by the industry. Every sailing ship has a sail plan that is adapted to the purpose of the vessel and the ability of the crew; each has a hull , rigging and masts to hold up the sails that use the wind to power the ship; the masts are supported by standing rigging and the sails are adjusted by running rigging . Hull shapes for sailing ships evolved from being relatively short and blunt to being longer and finer at
32899-431: The term " Chosŏn War" ( Chinese : 朝鮮戰爭 ; pinyin : Cháoxiǎn Zhànzhēng ) is sometimes used unofficially. The term " Hán (Korean) War" ( Chinese : 韓戰 ; pinyin : Hán Zhàn ) is most used in Taiwan (Republic of China), Hong Kong and Macau . In the US, the war was initially described by President Harry S. Truman as a " police action " as the US never formally declared war on its opponents, and
33096-458: The torture and starvation of prisoners of war by Pyongyang. North Korea became one of the most heavily bombed countries in history, and virtually all of Korea's major cities were destroyed. No peace treaty has been signed, making the war a frozen conflict . In South Korea, the war is usually referred to as the "625 War" ( 6·25 전쟁 ; 六二五戰爭 ), the "625 Upheaval" ( 6·25 동란 ; 六二五動亂 ; yugio dongnan ), or simply "625", reflecting
33293-435: The treaty was signed, Constitution captured HMS Levant and Cyane . The final naval action of the war occurred almost five months after the treaty on June 30, 1815 when the sloop USS Peacock captured the East India Company brig Nautilus , the last enemy ship captured by the U.S. Navy until World War II . After the war, the Navy's accomplishments paid off in the form of better funding, and it embarked on
33490-542: The upper and lower edges of the sails (and sometimes in between), in contrast to western rigs which only had a spar on the upper edge. Large Austronesian trading ships with as many as four sails were recorded by Han dynasty (206 BC – 220 AD) scholars as the kunlun bo or K'un-lun po (崑崙舶, lit. "ship of the Kunlun people"). They were booked by Chinese Buddhist pilgrims for passage to Southern India and Sri Lanka. Bas reliefs of large Javanese outriggers ships with various configurations of tanja sails are also found in
33687-415: The war by the Confederacy. During the Battle of Mobile Bay , mines were used to protect the harbor and sank the Union monitor USS Tecumseh . After Tecumseh sank, Admiral David G. Farragut famously said, "Damn the torpedoes, full speed ahead!". The forerunner of the modern submarine, CSS David , attacked USS New Ironsides using a spar torpedo . The Union ship was barely damaged and
33884-519: The war on June 17, 1778, and ships of the French Navy sent to the Western Hemisphere spent most of the year in the West Indies, and only sailed near the Thirteen Colonies during the Caribbean hurricane season from July until November. A French Navy fleet attempted landings in New York and Rhode Island in 1778, but ultimately failed to engage British forces. In 1779, a fleet commanded by Vice Admiral Charles Henri, comte d'Estaing assisted American forces attempting to recapture Savannah, Georgia . In 1780,
34081-465: The weakness of the United States Navy to again capture American merchant ships and sailors. After the Treaty of Ghent was signed, the United States looked at ending the piracy in the Mediterranean which had plagued American merchants for two decades. On March 3, 1815, Congress authorized deployment of naval power against Algiers, beginning the Second Barbary War. Two powerful squadrons under the command of Commodores Decatur and William Bainbridge , including
34278-404: The wind direction on the course sailed, and changing tack to bring the wind from one side of the vessel to the other. A sailing ship crew manages the running rigging of each square sail. Each sail has two sheets that control its lower corners, two braces that control the angle of the yard, two clewlines, four buntlines and two reef tackles. All these lines must be manned as the sail is deployed and
34475-435: The wind. The running rigging has three main roles, to support the sail structure, to shape the sail and to adjust its angle to the wind. Square-rigged vessels require more controlling lines than fore-and-aft rigged ones. Sailing ships prior to the mid-19th century used wood masts with hemp-fiber standing rigging. As rigs became taller by the end of the 19th century, masts relied more heavily on successive spars, stepped one atop
34672-442: The yard raised. They use a halyard to raise each yard and its sail; then they pull or ease the braces to set the angle of the yard across the vessel; they pull on sheets to haul lower corners of the sail, clews , out to yard below. Under way, the crew manages reef tackles , haul leeches , reef points , to manage the size and angle of the sail; bowlines pull the leading edge of the sail ( leech ) taut when close hauled. When furling
34869-405: Was carvel-built and large enough to be stable in heavy seas. It was capable of carrying a large cargo and the provisions needed for very long voyages. Later carracks were square-rigged on the foremast and mainmast and lateen-rigged on the mizzenmast . They had a high rounded stern with large aftcastle , forecastle and bowsprit at the stem. As the predecessor of the galleon , the carrack
35066-417: Was administered by a US–Soviet Union Joint Commission , as agreed at the Moscow Conference , to grant independence after a five-year trusteeship. Waiting five years for independence was unpopular among Koreans, and riots broke out. To contain them, the USAMGIK banned strikes on 8 December and outlawed the PRK Revolutionary Government and People's Committees on 12 December. Following further civilian unrest,
35263-414: Was almost entirely trained and focused on counterinsurgency, rather than conventional warfare. They were equipped and advised by a force of a few hundred American officers, who were successful in helping the ROKA to subdue guerrillas and hold its own against North Korean military (Korean People's Army, KPA) forces along the 38th parallel. Approximately 8,000 South Korean soldiers and police officers died in
35460-408: Was captured by the British frigate HMS Shannon under Captain Sir Philip Broke . Lawrence was mortally wounded and famously cried out, "Don't give up the ship!". Despite their earlier successes, by 1814 many of the Navy's best ships were blockaded in port and unable to prevent British incursions on land via the sea. During the summer of 1814, the British fought the Chesapeake Campaign , which
35657-404: Was climaxed by amphibious assaults against Washington and Baltimore . The capital fell to the British almost without a fight, and several American warships were burned at the Washington Navy Yard , including the 44-gun frigate USS Columbia . At Baltimore, the bombardment by Fort McHenry inspired Francis Scott Key to write " The Star-Spangled Banner ", and the hulks blocking the channel prevented
35854-408: Was declared. After considerable debate, three of the six frigates were authorized to be completed: United States , Constitution and Constellation . However, the first naval vessel to sail was USS Ganges , on May 24, 1798. At the same time, tensions between the U.S. and France developed into the Quasi-War, which originated from the Treaty of Alliance (1778) that had brought the French into
36051-440: Was finally declared in late 1783. The Revolutionary War was ended by the Treaty of Paris in 1783, and by 1785 the Continental Navy was disbanded and the remaining ships were sold. The frigate Alliance , which had fired the last shots of the American Revolutionary War, was also the last ship in the Navy. A faction within Congress wanted to keep the ship, but the new nation did not have the funds to keep her in service. Other than
36248-442: Was no US policy dealing with South Korea directly as a national interest, its proximity to Japan increased its importance. Said Kim: "The recognition that the security of Japan required a non-hostile Korea led directly to President Truman's decision to intervene ... The essential point ... is that the American response to the North Korean attack stemmed from considerations of U.S. policy toward Japan." Another consideration
36445-401: Was not included in the strategic Asian Defense Perimeter outlined by United States Secretary of State Dean Acheson . Military strategists were more concerned with the security of Europe against the Soviet Union than that of East Asia . The administration was worried a war in Korea could quickly escalate without American intervention. Diplomat John Foster Dulles stated: "To sit by while Korea
36642-438: Was not ready for an offensive operation because public opinion demanded an immediate attack. On March 8, 1862, the Confederate Navy initiated the first combat between ironclads when Virginia successfully attacked the blockade. The next day, Monitor engaged Virginia in the Battle of Hampton Roads . Their battle ended in a draw, and the Confederacy later lost Virginia when the ship was scuttled to prevent capture. Monitor
36839-770: Was not the case. Rather, the soldiers were indigenous to China, as part of China's longstanding ethnic Korean community, and were recruited to the PLA in the same way as any other Chinese citizen. According to the first official census in 1949, the population of North Korea numbered 9,620,000, and by mid-1950, North Korean forces numbered between 150,000 and 200,000 troops, organized into 10 infantry divisions, one tank division, and one air force division, with 210 fighter planes and 280 tanks, who captured scheduled objectives and territory, among them Kaesong, Chuncheon , Uijeongbu , and Ongjin. Their forces included 274 T-34-85 tanks, 200 artillery pieces, 110 attack bombers, 150 Yak fighter planes, and 35 reconnaissance aircraft. In addition to
37036-437: Was on July 7, 1798 when USS Delaware captured the French privateer Le Croyable , and the first victory over an enemy warship was on February 9, 1799 when the frigate Constellation captured the French frigate L'Insurgente . By the end of 1800, peace with France had been declared, and in 1801, to prevent a second disarmament of the Navy, the outgoing Federalist administration rushed through Congress an act authorizing
37233-494: Was one of the most influential ship designs in history; while ships became more specialized in the following centuries, the basic design remained unchanged throughout this period. Ships of this era were only able to sail approximately 70° into the wind and tacked from one side to the other across the wind with difficulty, which made it challenging to avoid shipwrecks when near shores or shoals during storms. Nonetheless, such vessels reached India around Africa with Vasco da Gama ,
37430-498: Was reduced to a single man over the course of engagements by the ROKA 8th Division . The second was annihilated by a two-battalion hammer-and-anvil maneuver by units of the ROKA 6th Division , resulting in a toll of 584 KPA guerrillas (480 killed, 104 captured) and 69 ROKA troops killed, plus 184 wounded. By the spring of 1950, guerrilla activity had mostly subsided; the border, too, was calm. By 1949, South Korean and US military actions had reduced indigenous communist guerrillas in
37627-437: Was rooted in the American seafaring tradition, which produced a large community of sailors, captains and shipbuilders during the colonial era. During the Revolution, several states operated their own navies. On June 12, 1775, the Rhode Island General Assembly passed a resolution creating a navy for the colony of Rhode Island. The same day, Governor Nicholas Cooke signed orders addressed to Captain Abraham Whipple , commander of
37824-406: Was so hastily scuttled that her hull and steam engine were basically intact, which gave the South's Stephen Mallory the idea of raising her and then armoring the upper sides with iron plate. The resulting ship was named CSS Virginia . Meanwhile, John Ericsson had similar ideas, and received funding to build USS Monitor . Winfield Scott , the commanding general of the U.S. Army at
38021-443: Was supported by the People's Republic of China and the Soviet Union , while South Korea was supported by the United Nations Command (UNC) led by the United States . The conflict was thus the first major proxy war of the Cold War between the Soviet Union and US. Fighting ended in 1953 with an armistice but no peace treaty , leading to the ongoing Korean conflict characterized by phases of diplomacy and confrontation. After
38218-429: Was the Soviet reaction if the US intervened. The Truman administration was fearful a Korean war was a diversionary assault that would escalate to a general war in Europe once the US committed in Korea. At the same time, "[t]here was no suggestion from anyone that the United Nations or the United States could back away from [the conflict]". Yugoslavia —a possible Soviet target because of the Tito-Stalin split —was vital to
38415-417: Was the prototype for the monitor warship and many more were built by the Union Navy. While the Confederacy built more ironclad ships during the war, they lacked the ability to build or purchase ships that could effectively counter the monitors. Along with ironclad ships, the new technologies of naval mines , which were known as torpedoes after the torpedo eel , and submarine warfare were introduced during
38612-414: Was unlawful for black men to serve in the Navy, but the shortage of men was so acute this law was frequently ignored. Discipline followed the customs of the Royal Navy but punishment was much milder than typical in European navies. Sodomy was rarely prosecuted. The Army abolished flogging as a punishment in 1812, but the Navy kept it until 1850. During the War of 1812, the Barbary states took advantage of
38809-413: Was withdrawn in 1823 ostensibly to deal with piracy in the Caribbean, and did not return to the African coast until the passage of the Webster–Ashburton treaty with Britain in 1842. After the treaty was passed, the United States used fewer ships than the treaty required, ordered the ships based far from the coast of Africa, and used ships that were too large to operate close to shore. Between 1845 and 1850,
