172-652: The Continental Iron Works was an American shipbuilding and engineering company founded in Greenpoint, Brooklyn , in 1861 by Thomas F. Rowland . It is best known for building a number of monitor warships for the United States Navy during the American Civil War , most notably the first of the type, USS  Monitor . Monitor ' s successful neutralization of the Confederate ironclad CSS Virginia in

344-732: A Homestead Act , a transcontinental railroad, the National Bank Act , authorization of United States Notes by the Legal Tender Act of 1862 , and the end of slavery in the District of Columbia . The Revenue Act of 1861 introduced income tax to help finance the war. In December 1860, the Crittenden Compromise was proposed to re-establish the Missouri Compromise line, by constitutionally banning slavery in territories to

516-601: A solar barque . Early Egyptians also knew how to fasten the planks of this ship together with mortise and tenon joints. The oldest known tidal dock in the world was built around 2500 BC during the Harappan civilisation at Lothal near the present day Mangrol harbour on the Gujarat coast in India . Other ports were probably at Balakot and Dwarka . However, it is probable that many small-scale ports, and not massive ports, were used for

688-512: A Baltimore newspaper editor, Frank Key Howard , after he criticized Lincoln in an editorial for ignoring Taney's ruling. In Missouri, an elected convention on secession voted to remain in the Union. When pro-Confederate Governor Claiborne Fox Jackson called out the state militia, it was attacked by federal forces under General Nathaniel Lyon , who chased the governor and rest of the State Guard to

860-667: A State to remain in the Union" was not among the "enumerated powers granted to Congress". A quarter of the US army—the Texas garrison—was surrendered in February to state forces by its general, David E. Twiggs , who joined the Confederacy. As Southerners resigned their Senate and House seats, Republicans could pass projects that had been blocked. These included the Morrill Tariff , land grant colleges,

1032-461: A blockade of the Confederacy to suffocate the South into surrender. Lincoln adopted parts of the plan but opted for a more active war strategy. In April 1861, Lincoln announced a blockade of all Southern ports; commercial ships could not get insurance, ending regular traffic. The South blundered by embargoing cotton exports before the blockade was fully effective; by the time they reversed this decision, it

1204-426: A broad beam and heavily curved at both ends. Another important ship type was the galley, which was constructed with both sails and oars. The first extant treatise on shipbuilding was written c.  1436 by Michael of Rhodes, a man who began his career as an oarsman on a Venetian galley in 1401 and worked his way up into officer positions. He wrote and illustrated a book that contains a treatise on shipbuilding,

1376-620: A conventional furnace but with thinner walls, increasing the transfer of heat and thus efficiency. These corrugated furnaces were a popular product and were adopted on many merchant ships, as well as US Navy torpedo boats and other warships, such as the battleship Maine . The company built the first Thornycroft boilers in the United States—;for the Navy's first torpedo boat , USS  Cushing —as well as manufacturing its own line of boilers. Other popular welded products produced by

1548-410: A curved, progressive joint could not be achieved. One study finds that there were considerable improvements in ship speed from 1750 to 1850: "we find that average sailing speeds of British ships in moderate to strong winds rose by nearly a third. Driving this steady progress seems to be the continuous evolution of sails and rigging, and improved hulls that allowed a greater area of sail to be set safely in

1720-681: A draft law in April 1862 for men aged 18–35, with exemptions for overseers, government officials, and clergymen. The U.S. Congress followed in July, authorizing a militia draft within states that could not meet their quota with volunteers. European immigrants joined the Union Army in large numbers, including 177,000 born in Germany and 144,000 in Ireland. About 50,000 Canadians served, around 2,500 of whom were black. When

1892-478: A firm hand by Lincoln tamed Seward, who was a staunch Lincoln ally. Lincoln decided holding the fort, which would require reinforcing it, was the only workable option. On April 6, Lincoln informed the Governor of South Carolina that a ship with food but no ammunition would attempt to supply the fort. Historian McPherson describes this win-win approach as "the first sign of the mastery that would mark Lincoln's presidency";

2064-526: A gas holder for a fourth that at the time was the country's largest, described by the American Society of Mechanical Engineers as "a noted achievement in gas engineering". A wide variety of other metal products was also produced by the Continental Works through the 1870s, such as giant cauldrons and vats , machine tools, lifecars for lifesaving clubs, and torpedo casings for the Navy. In 1869,

2236-573: A given wind. By contrast, looking at every voyage between the Netherlands and East Indies undertaken by the Dutch East India Company from 1595 to 1795, we find that journey time fell only by 10 percent, with no improvement in the heavy mortality, averaging six percent per voyage, of those aboard." Initially copying wooden construction traditions with a frame over which the hull was fastened, Isambard Kingdom Brunel 's Great Britain of 1843

2408-499: A high degree of commercialization and an increase in trade. Large numbers of ships were built to meet the demand. The Ming voyages were large in size, numbering as many as 300 ships and 28,000 men. The shipbuilders were brought from different places in China to the shipyard in Nanjing , including Zhejiang , Jiangxi , Fujian , and Huguang (now the provinces of Hubei and Hunan ). One of

2580-505: A mainstay of the company's business. The company exhibited its welding expertise at the World's Columbian Exposition in 1893 and again at the St. Louis World's Fair in 1904. By the 1890s, the company had become the nation's sole producer of welded, corrugated boiler furnaces, which were used in both marine and stationary boilers. The advantage of corrugation was that it could provide the same strength as

2752-471: A man until she died in 1915 at the age of 71. The small U.S. Navy of 1861 rapidly expanded to 6,000 officers and 45,000 sailors by 1865, with 671 vessels totaling 510,396 tons. Its mission was to blockade Confederate ports, control the river system, defend against Confederate raiders on the high seas, and be ready for a possible war with the British Royal Navy . The main riverine war was fought in

2924-479: A number of warships, including the battleship USS  Maine , and its welding expertise was showcased at the World's Columbian Exposition in 1893 and the St. Louis World's Fair in 1904. During World War I , the Continental Works built munitions for the war effort, including depth charge casings, and after the war, it increasingly turned to the manufacture of gas mains and large-diameter welded water pipes. The company's assets were liquidated in 1928, following

3096-480: A particular task by 75 men. He also developed new working methods, such as heating armor plates before bending them. By the end of the war, the Works covered an area of eight acres, and is said to have been so crammed with buildings and wood and iron stores that movement around the yard by its employees had become both difficult and hazardous. At its peak, the firm's wartime workforce was in the order of 1,000 employees. With

3268-447: A patriotic fire under the North. On April 15, Lincoln called on the states to field 75,000 volunteer troops for 90 days; impassioned Union states met the quotas quickly. On May 3, 1861, Lincoln called for an additional 42,000 volunteers for three years. Shortly after this, Virginia , Tennessee , Arkansas , and North Carolina seceded and joined the Confederacy. To reward Virginia,

3440-415: A radically new type of ironclad warship with a low freeboard and revolving gun turret. On 4 October, he signed a contract with the Navy for construction of the new vessel, on the basis that Ericsson and his backers would assume all financial risk for the project and that the ship would be launched within 100 days. As Ericsson wanted to closely supervise the project, he turned to local New York companies for

3612-406: A range of sailing rigs that included the crab claw sail . The origins of this technology is difficult to date, relying largely on linguistics (studying the words for parts of boats), the written comments of people from other cultures, including the observations of European explorers at the time of first contact and the later more systematic ethnographic observations of the types of craft in use. There

3784-457: A ship has often represented the most advanced structure that the society building it could produce. Some key industrial advances were developed to support shipbuilding, for instance the sawing of timbers by mechanical saws propelled by windmills in Dutch shipyards during the first half of the 17th century. The design process saw the early adoption of the logarithm (invented in 1615) to generate

3956-555: A significant number of workers, and generate income as the shipbuilding market is global . American Civil War The American Civil War (April 12, 1861 – May 26, 1865; also known by other names ) was a civil war in the United States between the Union ("the North") and the Confederacy ("the South"), which was formed in 1861 by states that had seceded from

4128-863: A similar design. Austronesians established the Austronesian maritime trade network at around 1000 to 600 BC, linking Southeast Asia with East Asia, South Asia, the Middle East, and later East Africa. The route later became part of the Spice trade network and the Maritime Silk Road . The naval history of China stems back to the Spring and Autumn period (722 BC–481 BC) of the ancient Chinese Zhou dynasty . The Chinese built large rectangular barges known as "castle ships", which were essentially floating fortresses complete with multiple decks with guarded ramparts . However,

4300-411: A single piece of hollowed-out log. At the sides were two planks, and two horseshoe-shaped wood pieces formed the prow and stern . These were fitted tightly together edge-to-edge with dowels inserted into holes in between, and then lashed to each other with ropes (made from rattan or fiber) wrapped around protruding lugs on the planks. This characteristic and ancient Austronesian boatbuilding practice

4472-518: A treatise on mathematics, much material on astrology, and other materials. His treatise on shipbuilding treats three kinds of galleys and two kinds of round ships. Shipbuilders in the Ming dynasty (1368~1644) were not the same as the shipbuilders in other Chinese dynasties, due to hundreds of years of accumulated experiences and rapid changes in the Ming dynasty. Shipbuilders in the Ming dynasty primarily worked for

4644-467: Is a famous example). Later Great Britain ' s iron hull was sheathed in wood to enable it to carry a copper-based sheathing . Brunel's Great Eastern represented the next great development in shipbuilding. Built-in association with John Scott Russell , it used longitudinal stringers for strength, inner and outer hulls, and bulkheads to form multiple watertight compartments. Steel also supplanted wrought iron when it became readily available in

4816-654: Is a possibility that they may have reached the Americas . After the 11th century, a new type of ship called djong or jong was recorded in Java and Bali. This type of ship was built using wooden dowels and treenails, unlike the kunlun bo which used vegetal fibres for lashings. The empire of Majapahit used jong, built in northern Java, for transporting troops overseas. The jongs were transport ships which could carry 100–2000 tons of cargo and 50–1000 people, 28.99–88.56 meter in length. The exact number of jong fielded by Majapahit

4988-631: Is from the 6th to 5th millennium BC of the Ubaid period of Mesopotamia . They were made from bundled reeds coated in bitumen and had bipod masts. They sailed in shallow coastal waters of the Persian Gulf . Evidence from Ancient Egypt shows that the early Egyptians knew how to assemble planks of wood into a ship hull as early as 3100 BC. Egyptian pottery as old as 4000 BC shows designs of early fluvial boats or other means for navigation. The Archaeological Institute of America reports that some of

5160-600: Is known as the " lashed-lug " technique. They were commonly caulked with pastes made from various plants as well as tapa bark and fibres which would expand when wet, further tightening joints and making the hull watertight. They formed the shell of the boat, which was then reinforced by horizontal ribs. Shipwrecks of Austronesian ships can be identified from this construction as well as the absence of metal nails. Austronesian ships traditionally had no central rudders but were instead steered using an oar on one side. Austronesians traditionally made their sails from woven mats of

5332-571: Is noted in the works of Ibn Jubayr . The ships of Ancient Egypt's Eighteenth Dynasty were typically about 25 meters (80 ft) in length and had a single mast , sometimes consisting of two poles lashed together at the top making an "A" shape. They mounted a single square sail on a yard , with an additional spar along the bottom of the sail. These ships could also be oar propelled. The ocean- and sea-going ships of Ancient Egypt were constructed with cedar wood, most likely hailing from Lebanon. The ships of Phoenicia seem to have been of

5504-499: Is only a small body of archaeological evidence available. Since Island Southeast Asia contained effective maritime transport between its very large number of islands long before Austronesian seafaring, it is argued that Austronesians adopted an existing maritime technology from the existing inhabitants of this region. Austronesian ships varied from simple canoes to large multihull ships. The simplest form of all ancestral Austronesian boats had five parts. The bottom part consists of

5676-603: Is the fading myth of the Lost Cause of the Confederacy . The war was among the first to use industrial warfare . Railroads, the electrical telegraph , steamships, the ironclad warship , and mass-produced weapons were widely used. The war left an estimated 698,000 soldiers dead, along with an undetermined number of civilian casualties, making the Civil War the deadliest military conflict in American history. The technology and brutality of

5848-539: Is the settlement of Australia between 50,000 and 60,000 years ago. This almost certainly involved rafts , possibly equipped with some sort of sail . Much of the development beyond that raft technology occurred in the "nursery" areas of the Mediterranean and in Maritime Southeast Asia . Favoured by warmer waters and a number of inter-visible islands, boats (and, later, ships) with water-tight hulls (unlike

6020-411: Is unknown, but the largest number of jong deployed in an expedition is about 400 jongs, when Majapahit attacked Pasai, in 1350. Until recently, Viking longships were seen as marking an advance on traditional clinker -built hulls where leather thongs were used to join plank boards. This consensus has recently been challenged. Haywood has argued that earlier Frankish and Anglo-Saxon nautical practice

6192-571: The ghe mành . Early Egyptians also knew how to assemble planks of wood with treenails to fasten them together, using pitch for caulking the seams. The " Khufu ship ", a 43.6-meter vessel sealed into a pit in the Giza pyramid complex at the foot of the Great Pyramid of Giza in the Fourth Dynasty around 2500 BC, is a full-size surviving example which may have fulfilled the symbolic function of

6364-579: The k'un-lun po or kunlun bo ("ship of the k'un-lun [dark-skinned southern people]"). These ships used two types of sail of their invention, the junk sail and tanja sail . Large ships are about 50–60 metres (164–197 ft) long, had 5.2–7.8 metres (17–26 ft) tall freeboard , each carrying provisions enough for a year, and could carry 200–1000 people. The Chinese recorded that these Southeast Asian ships were hired for passage to South Asia by Chinese Buddhist pilgrims and travelers, because they did not build seaworthy ships of their own until around

6536-583: The 1860 presidential election . Seven Southern slave states responded to Lincoln's victory by seceding from the United States and forming the Confederacy. The Confederacy seized U.S. forts and other federal assets within their borders. The war began on April 12, 1861, when the Confederacy bombarded Fort Sumter in South Carolina . A wave of enthusiasm for war swept over the North and South, as military recruitment soared. Four more Southern states seceded after

6708-702: The Abbasid period. Mughal Empire had a large shipbuilding industry, which was largely centred in the Bengal Subah . Economic historian Indrajit Ray estimates shipbuilding output of Bengal during the sixteenth and seventeenth centuries at 223,250 tons annually, compared with 23,061 tons produced in nineteen colonies in North America from 1769 to 1771. He also assesses ship repairing as very advanced in Bengal. Documents from 1506, for example, refer to watercraft on

6880-536: The Battle of Gettysburg . Western successes led to General Ulysses S. Grant 's command of all Union armies in 1864. Inflicting an ever-tightening naval blockade of Confederate ports, the Union marshaled resources and manpower to attack the Confederacy from all directions. This led to the fall of Atlanta in 1864 to Union General William Tecumseh Sherman , followed by his March to the Sea . The last significant battles raged around

7052-506: The Confederate ironclad CSS Virginia was threatening the Union fleet. Monitor ' s success in neutralizing the threat from Virginia in the ensuing Battle of Hampton Roads —the world's first battle between ironclads—sparked a "monitor fever" in Washington, and contracts for many more of the same ship type, dubbed monitors after the original, were quickly signed. Ericsson would eventually subcontract with Continental for

7224-603: The Confederate States of America , on February 4, 1861. They took control of federal forts and other properties within their boundaries, with little resistance from outgoing President James Buchanan , whose term ended on March 4. Buchanan said the Dred Scott decision was proof the Southern states had no reason to secede and that the Union "was intended to be perpetual". He added, however, that "The power by force of arms to compel

7396-598: The Emancipation Proclamation went into effect in January 1863, ex-slaves were energetically recruited to meet state quotas. States and local communities offered higher cash bonuses for white volunteers. Congress tightened the draft law in March 1863. Men selected in the draft could provide substitutes or, until mid-1864, pay commutation money. Many eligibles pooled their money to cover the cost of anyone drafted. Families used

7568-552: The Emancipation Proclamation , which declared all slaves in rebel states to be free, applying to more than 3.5 million of the 4 million enslaved people in the country. To the west, the Union first destroyed the Confederacy's river navy by the summer of 1862, then much of its western armies, and seized New Orleans . The successful 1863 Union siege of Vicksburg split the Confederacy in two at the Mississippi River , while Confederate General Robert E. Lee 's incursion north failed at

7740-563: The Harlem River at Highbridge, Bronx , for the transport of water from the Croton Aqueduct to a newly built reservoir in Manhattan. Sneden & Co. won the contract with a bid of $ 49,000 (equivalent to $ 1,661,644 in 2023)—almost $ 20,000 (equivalent to $ 678,222 in 2023) less than the next lowest bid. A month after signing the contract, Sneden requested its voiding on the grounds of

7912-533: The Napoleonic Wars were still built more or less to the same basic plan as those of the Spanish Armada of two centuries earlier, although there had been numerous subtle improvements in ship design and construction throughout this period. For instance, the introduction of tumblehome , adjustments to the shapes of sails and hulls, the introduction of the wheel, the introduction of hardened copper fastenings below

8084-453: The Sierra Leone river carrying 120 men. Others refer to Guinea coast peoples using war canoes of varying sizes – some 70 feet in length, 7–8 feet broad, with sharp pointed ends, rowing benches on the side, and quarterdecks or forecastles build of reeds. The watercraft included miscellaneous facilities, such as cooking hearths, and storage spaces for the crew's sleeping mats. From

The Confederacy's efforts to obtain warships from Great Britain failed, as Britain had no interest in selling warships to a nation at war with a stronger enemy and feared souring relations with the U.S. By early 1861, General Winfield Scott had devised the Anaconda Plan to win the war with minimal bloodshed, calling for

8428-507: The boiler furnaces of the monitor USS Monadnock . Another early application of the company's welding techniques was the manufacture of gas reservoirs used to store highly pressurized gas in self-propelled torpedoes, a weapon type that at the time was the subject of increasing experimentation by the Russian and other European governments. The Continental Works later pioneered scarf- and gas-welding , with welded products gradually growing to become

8600-413: The gun turrets for three other monitors during the Civil War, and later, in the 1870s, the hull of another, which was later completed at other shipyards. The Continental Works built a small number of ships in the decades after the Civil War, most of which were merchant vessels of one kind or another. [[]] Shipbuilding Until recently, with the development of complex non-maritime technologies,

8772-515: The "flow through" structure of a raft) could be developed. The ships of ancient Egypt were built by joining the hull planks together, edge to edge, with tenons set in mortices cut in the mating edges. A similar technique, but with the tenons being pinned in position by dowels, was used in the Mediterranean for most of classical antiquity . Both these variants are "shell first" techniques, where any reinforcing frames are inserted after assembly of

8944-406: The 168,649 men procured for the Union through the draft, 117,986 were substitutes, leaving only 50,663 who were conscripted. In the North and South, draft laws were highly unpopular. In the North, some 120,000 men evaded conscription, many fleeing to Canada, and another 280,000 soldiers deserted during the war. At least 100,000 Southerners deserted, about 10 percent of the total. Southern desertion

9116-536: The 17th century, some kingdoms added brass or iron cannons to their vessels. By the 18th century, however, the use of swivel cannons on war canoes accelerated. The city-state of Lagos , for instance, deployed war canoes armed with swivel cannons. With the development of the carrack , the west moved into a new era of ship construction by building the first regular oceangoing vessels. In a relatively short time, these ships grew to an unprecedented size, complexity, and cost. Shipyards became large industrial complexes, and

9288-509: The 1862 Battle of Hampton Roads —the world's first battle between ironclad warships—would come to heavily influence American naval strategy both during and after the war. After the Civil War, a severe shipbuilding slump in New York persuaded the Continental Works to diversify into the manufacture of equipment for the growing gas lighting industry, for which the company built gas holders , gas mains and complete gas plants . In 1888,

9460-690: The 5,000-year-old ship may have even belonged to Pharaoh Aha . The Austronesian expansion , which began c.  3000 BC with migration from Taiwan to the island of Luzon in the Philippines , spread across Island Southeast Asia . Then, between 1500 BC and 1500 AD they settled uninhabited islands of the Pacific, and also sailed westward to Madagascar. This is associated with distinctive maritime technology: lashed lug construction techniques (both in outrigger canoes and in large planked sailing vessels), various types of outrigger and twin-hulled canoes and

9632-590: The 8–9th century AD. Austronesians (especially from western Island Southeast Asia ) were trading in the Indian Ocean as far as Africa during this period. By around 50 to 500 AD, a group of Austronesians, believed to be from the southeastern coasts of Borneo (possibly a mixed group related to the modern Ma'anyan , Banjar , and/or the Dayak people ) crossed the Indian Ocean and colonized Madagascar . This resulted in

9804-731: The Admiral Zheng He . Six voyages were conducted under the Yongle Emperor's reign, the last of which returned to China in 1422. After the Yongle Emperor's death in 1424, his successor the Hongxi Emperor ordered the suspension of the voyages. The seventh and final voyage began in 1430, sent by the Xuande Emperor . Although the Hongxi and Xuande Emperors did not emphasize sailing as much as the Yongle Emperor, they were not against it. This led to

9976-490: The Atlantic and Pacific oceans. Insurance rates soared, and the American flag virtually disappeared from international waters, though reflagging ships with European flags allowed them to continue operating unmolested. After the war, the U.S. government demanded Britain compensate it for the damage caused by blockade runners and raiders outfitted in British ports. Britain paid the U.S. $ 15 million in 1871, but only for commerce raiding. Dinçaslan argues that another outcome of

10148-401: The Bahamas in exchange for high-priced cotton. Many were lightweight and designed for speed, only carrying small amounts of cotton back to England. When the Union Navy seized a blockade runner, the ship and cargo were condemned as a prize of war and sold, with proceeds given to the Navy sailors; the captured crewmen, mostly British, were released. The Southern economy nearly collapsed during

10320-400: The British response to the U.S. was toned down, helping avert war. In 1862, the British government considered mediating between the Union and Confederacy, though such an offer would have risked war with the U.S. British Prime Minister Lord Palmerston reportedly read Uncle Tom's Cabin three times when deciding what his decision would be. The Union victory at the Battle of Antietam caused

10492-438: The British to delay this decision. The Emancipation Proclamation increased the political liability of supporting the Confederacy. Realizing that Washington could not intervene in Mexico as long as the Confederacy controlled Texas, France invaded Mexico in 1861 and installed the Habsburg Austrian archduke Maximilian I as emperor. Washington repeatedly protested France's violation of the Monroe Doctrine . Despite sympathy for

10664-404: The Chinese vessels during this era were essentially fluvial (riverine). True ocean-going Chinese fleets did not appear until the 10th century Song dynasty . There is considerable knowledge regarding shipbuilding and seafaring in the ancient Mediterranean. Large multi-masted seafaring ships of Southeast Asian Austronesians first started appearing in Chinese records during the Han dynasty as

Southern Chinese junks showed characteristics of Austronesian ships that they are made using timbers of tropical origin, with keeled, V-shaped hull. This is different from northern Chinese junks, which are developed from flat-bottomed riverine boats. The northern Chinese junks were primarily built of pine or fir wood, had flat bottoms with no keel, water-tight bulkheads with no frames, transom (squared) stern and stem, and have their planks fastened with iron nails or clamps. It

11008-417: The Civil War foreshadowed the coming World Wars . The origins of the war were rooted in the desire of the Southern states to preserve the institution of slavery . Historians in the 21st century overwhelmingly agree on the centrality of slavery in the conflict. They disagree on which aspects (ideological, economic, political, or social) were most important, and on the North 's reasons for refusing to allow

11180-404: The Commonwealth, which at its greatest extent was over half the state, and it went into exile after October 1862. After Virginia's secession, a Unionist government in Wheeling asked 48 counties to vote on an ordinance to create a new state in October 1861. A voter turnout of 34% approved the statehood bill (96% approving). Twenty-four secessionist counties were included in the new state, and

11352-400: The Confederacy refused to exchange black prisoners. After that, about 56,000 of the 409,000 POWs died in prisons, accounting for 10 percent of the conflict's fatalities. Historian Elizabeth D. Leonard writes that between 500 and 1,000 women enlisted as soldiers on both sides, disguised as men. Women also served as spies, resistance activists, nurses, and hospital personnel. Women served on

11524-410: The Confederacy, France's seizure of Mexico ultimately deterred it from war with the Union. Confederate offers late in the war to end slavery in return for diplomatic recognition were not seriously considered by London or Paris. After 1863, the Polish revolt against Russia further distracted the European powers and ensured they remained neutral. Russia supported the Union, largely because it believed

11696-450: The Confederacy. According to Lincoln, the American people had shown they had been successful in establishing and administering a republic, but a third challenge faced the nation: maintaining a republic based on the people's vote, in the face of an attempt to destroy it. Lincoln's election provoked South Carolina 's legislature to call a state convention to consider secession. South Carolina had done more than any other state to advance

11868-519: The Confederate capital was moved to Richmond . Maryland , Delaware , Missouri , West Virginia and Kentucky were slave states whose people had divided loyalties to Northern and Southern businesses and family members. Some men enlisted in the Union Army and others in the Confederate Army. West Virginia separated from Virginia and was admitted to the Union on June 20, 1863, though half its counties were secessionist. Maryland's territory surrounded Washington, D.C. , and could cut it off from

12040-410: The Continental Works, and are included here for the sake of completeness. The Continental Iron Works built a total of eight warships for the United States Navy during the Civil War—seven monitors and one gunboat. Two of the monitors were not completed by war's end and consequently never commissioned. In addition to the United States Navy warships built by the Continental Iron Works, it also built

All were held without trial, with Lincoln ignoring a ruling on June 1, 1861, by Supreme Court Chief Justice Roger Taney , not speaking for the Court, that only Congress could suspend habeas corpus ( Ex parte Merryman ). Federal troops imprisoned

12384-606: The Han dynasty junk ship design in the same century. The Chinese were using square sails during the Han dynasty and adopted the Austronesian junk sail later in the 12th century. Iconographic remains show that Chinese ships before the 12th century used square sails, and the junk rig of Chinese ships is believed to be developed from tilted sails . Southern Chinese junks were based on keeled and multi-planked Austronesian ship known as po by

12556-695: The Harappan maritime trade. Ships from the harbour at these ancient port cities established trade with Mesopotamia . Shipbuilding and boatmaking may have been prosperous industries in ancient India. Native labourers may have manufactured the flotilla of boats used by Alexander the Great to navigate across the Hydaspes and even the Indus , under Nearchos . The Indians also exported teak for shipbuilding to ancient Persia . Other references to Indian timber used for shipbuilding

12728-420: The Navy. The Continental Iron Works also secured contracts during the war for construction of the turrets of another three monitors, and additionally built the iron-hulled double-ended gunboat Muscoota . In the course of building the monitors, Continental's proprietor, Thomas Rowland, invented a number of new machine tools to expedite the work, one of which is said to have reduced the required workforce for

12900-648: The North. It had anti-Lincoln officials who tolerated anti-army rioting in Baltimore and the burning of bridges, both aimed at hindering the passage of troops to the South. Maryland's legislature voted overwhelmingly to stay in the Union, but rejected hostilities with its southern neighbors, voting to close Maryland's rail lines to prevent their use for war. Lincoln responded by establishing martial law and unilaterally suspending habeas corpus in Maryland, along with sending in militia units. Lincoln took control of Maryland and

13072-1025: The South regarded it as insufficient. The remaining eight slave states rejected pleas to join the Confederacy, following a no-vote in Virginia's First Secessionist Convention on April 4. On March 4, Lincoln was sworn in as president. In his inaugural address , he argued that the Constitution was a more perfect union than the earlier Articles of Confederation and Perpetual Union , was a binding contract, and called secession "legally void". He did not intend to invade Southern states, nor to end slavery where it existed, but he said he would use force to maintain possession of federal property, including forts, arsenals, mints, and customhouses that had been seized. The government would not try to recover post offices, and if resisted, mail delivery would end at state lines. Where conditions did not allow peaceful enforcement of federal law, US marshals and judges would be withdrawn. No mention

13244-457: The South's post-war recovery. Cotton diplomacy proved a failure as Europe had a surplus of cotton, while the 1860–62 crop failures in Europe made the North's grain exports critically important. It also helped turn European opinion against the Confederacy. It was said that "King Corn was more powerful than King Cotton," as U.S. grain went from a quarter to almost half of British imports. Meanwhile,

13416-530: The South. The Confederacy turned to foreign sources, connecting with financiers and companies like S. Isaac, Campbell & Company and the London Armoury Company in Britain, becoming the Confederacy's main source of arms. To transport arms safely to the Confederacy, British investors built small, fast, steam-driven blockade runners that traded arms and supplies from Britain, through Bermuda, Cuba, and

13588-417: The Southern states to secede. The pseudo-historical Lost Cause ideology denies that slavery was the principal cause of the secession, a view disproven by historical evidence, notably some of the seceding states' own secession documents . After leaving the Union, Mississippi issued a declaration stating, "Our position is thoroughly identified with the institution of slavery—the greatest material interest of

13760-542: The U.S. and Britain over the Trent affair , which began when U.S. Navy personnel boarded the British ship Trent and seized two Confederate diplomats. However, London and Washington smoothed this over after Lincoln released the two men. Prince Albert left his deathbed to issue diplomatic instructions to Lord Lyons during the Trent affair. His request was honored, and, as a result,

13932-471: The Union Army or pro-Union guerrilla groups. Although they came from all classes, most Southern Unionists differed socially, culturally, and economically from their region’s dominant prewar, slave-owning planter class. At the war's start, a parole system operated, under which captives agreed not to fight until exchanged. They were held in camps run by their army, paid, but not allowed to perform any military duties. The system of exchanges collapsed in 1863 when

14104-451: The Union blockade. The Confederacy purchased warships from commercial shipbuilders in Britain, with the most famous being the CSS ; Alabama , which caused considerable damage and led to serious postwar disputes . However, public opinion against slavery in Britain created a political liability for politicians, where the anti-slavery movement was powerful. War loomed in late 1861 between

14276-460: The Union hospital ship Red Rover and nursed Union and Confederate troops at field hospitals. Mary Edwards Walker , the only woman ever to receive the Medal of Honor , served in the Union Army and was given the medal for treating the wounded during the war. One woman, Jennie Hodgers, fought for the Union under the name Albert D. J. Cashier. After she returned to civilian life, she continued to live as

14448-488: The Union would win if it could resupply and hold the fort, and the South would be the aggressor if it opened fire on an unarmed ship supplying starving men. An April 9 Confederate cabinet meeting resulted in Davis ordering General P. G. T. Beauregard to take the fort before supplies reached it. At 4:30 am on April 12, Confederate forces fired the first of 4,000 shells at the fort; it fell the next day. The loss of Fort Sumter lit

14620-433: The Union, this was never likely, so they sought to bring them in as mediators. The Union worked to block this and threatened war if any country recognized the Confederacy. In 1861, Southerners voluntarily embargoed cotton shipments, hoping to start an economic depression in Europe that would force Britain to enter the war, but this failed. Worse, Europe turned to Egypt and India for cotton, which they found superior, hindering

14792-473: The Union-held Fort Sumter. Fort Sumter is located in the harbor of Charleston , South Carolina. Its status had been contentious for months. Outgoing President Buchanan had dithered in reinforcing its garrison, commanded by Major Robert Anderson . Anderson took matters into his own hands and on December 26, 1860, under the cover of darkness, sailed the garrison from the poorly placed Fort Moultrie to

14964-411: The Union. The central conflict leading to war was a dispute over whether slavery should be permitted to expand into the western territories, leading to more slave states , or be prohibited from doing so, which many believed would place slavery on a course of ultimate extinction. Decades of controversy over slavery were brought to a head when Abraham Lincoln , who opposed slavery's expansion, won

15136-428: The United States in a 15-year period just before the war was a grand total of two. During the war, thousands of Liberty ships and Victory ships were built, many of them in shipyards that did not exist before the war. And, they were built by a workforce consisting largely of women and other inexperienced workers who had never seen a ship before (or even the ocean). After World War II , shipbuilding (which encompasses

15308-620: The West, where major rivers gave access to the Confederate heartland. The U.S. Navy eventually controlled the Red, Tennessee, Cumberland, Mississippi, and Ohio rivers. In the East, the Navy shelled Confederate forts and supported coastal army operations. The Civil War occurred during the early stages of the industrial revolution, leading to naval innovations, notably the ironclad warship . The Confederacy, recognizing

15480-515: The blockade was the rise of oil as a prominent commodity. The declining whale oil industry took a blow as many old whaling ships were used in blockade efforts, such as the Stone Fleet , and Confederate raiders harassed Union whalers. Oil products, especially kerosene, began replacing whale oil in lamps, increasing oil's importance long before it became fuel for combustion engines. Although the Confederacy hoped Britain and France would join them against

15652-407: The business. Shipbuilding contracts for the Continental Works also declined sharply, but the firm had done better during the war than some other Naval contractors, and was evidently in a more sound financial position. More importantly, while the company continued to accept shipbuilding contracts when available, it began to diversify its business into other areas. The most important of these initially

15824-436: The company accepted a contract to build a swing bridge , of the bowstring girder type, across Bushwick Inlet. The bridge, designed by Rowland himself and capable of sustaining a rolling load of 60 tons or distributed load of 300, was completed by 1872. While the company secured only a handful of shipbuilding contracts after the Civil War, it nonetheless built a number of notable vessels during this period. In 1871 for example,

15996-495: The company built the composite steam yacht Day Dream for Pacific Mail founder William Henry Aspinwall . Designed by Continental employee Lucius A. Smith, it was one of the first steam yachts built in the United States. In 1874, the Continental Works declined an offer from the Navy Department to build a new monitor, due to the terms of the proposed contract. Shortly thereafter, however, New York engineer Phineas Burgess took

16168-587: The company built what was then the largest gas holder in the United States. Another notable achievement of the company in the 1880s was the construction of the country's first steel- hulled ferryboats . In the 1870s, the Continental Works became a pioneer in welding technology, and many innovative welded products would subsequently be produced by it, such as welded corrugated boiler furnaces for ships and other applications, gas-illuminated buoys , steel digesters for wood pulping and welded casings for torpedoes . The company supplied corrugated boiler furnaces for

16340-528: The company through to the beginning of World War I included gas-illuminated buoys , and steel digesters used to convert wood to pulp for paper-making. During the Spanish–American War of 1898, the company produced thousands of torpedo casings for the Navy. During World War I, the Continental Iron Works manufactured welded depth charge casings and other munitions for the war effort. After

16512-409: The construction of another six monitors during the war—four of the single-turret type like the original, and the two larger, double-turreted monitors Onondaga and Puritan . All would see service during the war with the exception of the largest, Puritan , completion of which was delayed by design changes and unavailability of the main armament, and Cohoes , the design of which was botched by

16684-453: The contract for the new Amphitrite -class monitor Monadnock , and Continental then accepted a subcontract from him to build the ship's hull. It was duly constructed by Continental at Greenpoint, before being knocked down into sections for transportation overland to Vallejo, California , to be reassembled by Burgess. Construction of the vessel was subsequently suspended by government indecision—causing great financial loss to Burgess in

16856-471: The crisis was Secretary of State William H. Seward , who had been Lincoln's rival for the Republican nomination . Embittered by his defeat, Seward agreed to support Lincoln's candidacy only after he was guaranteed the executive office then considered the second most powerful. In the early stages of Lincoln's presidency Seward held little regard for him, due to his perceived inexperience. Seward viewed himself as

17028-417: The curves used to produce the shape of a hull , especially when scaling up these curves accurately in the mould loft . Shipbuilding and ship repairs, both commercial and military, are referred to as naval engineering . The construction of boats is a similar activity called boat building . The dismantling of ships is called ship breaking . The earliest evidence of maritime transport by modern humans

17200-635: The de facto head of government, the " prime minister " behind the throne. Seward attempted to engage in unauthorized and indirect negotiations that failed. Lincoln was determined to hold all remaining Union-occupied forts in the Confederacy: Fort Monroe in Virginia, Fort Pickens , Fort Jefferson , and Fort Taylor in Florida, and Fort Sumter in South Carolina. The American Civil War began on April 12, 1861, when Confederate forces opened fire on

17372-495: The end of the Ming dynasty in 1644. During this period, Chinese navigation technology did not make any progress and even declined in some aspect. In the Islamic world, shipbuilding thrived at Basra and Alexandria . The dhow , felucca , baghlah , and the sambuk became symbols of successful maritime trade around the Indian Ocean from the ports of East Africa to Southeast Asia and the ports of Sindh and Hind (India) during

17544-405: The end of the war in 1865, the American shipbuilding industry entered a severe and prolonged slump, caused partly by the Navy dumping a large number of ships now surplus to its requirements on the market, and partly by economic changes brought about by the conflict. The New York region was particularly badly affected, with many of its most prominent shipbuilding and marine engineering plants leaving

17716-486: The ensuing guerrilla war engaged about 40,000 federal troops for much of the war. Congress admitted West Virginia to the Union on June 20, 1863. West Virginians provided about 20,000 soldiers to each side in the war. A Unionist secession attempt occurred in East Tennessee , but was suppressed by the Confederacy, which arrested over 3,000 men suspected of loyalty to the Union; they were held without trial. The Civil War

17888-481: The essential role of cotton in the European economy. The European aristocracy was "absolutely gleeful in pronouncing the American debacle as proof that the entire experiment in popular government had failed. European government leaders welcomed the fragmentation of the ascendant American Republic." However, a European public with liberal sensibilities remained, which the U.S. sought to appeal to by building connections with

18060-410: The free-versus-slave status of the new territories was a critical issue, both for the North, where anti-slavery sentiment had grown, and for the South, where the fear of slavery's abolition had grown. Another factor leading to secession and the formation of the Confederacy was the development of white Southern nationalism in the preceding decades. The primary reason for the North to reject secession

18232-575: The government, under command of the Ministry of Public Works . During the early years of the Ming dynasty, the Ming government maintained an open policy towards sailing. Between 1405 and 1433, the government conducted seven diplomatic Ming treasure voyages to over thirty countries in Southeast Asia, India, the Middle East and Eastern Africa. The voyages were initiated by the Yongle Emperor , and led by

18404-439: The homefront economy could no longer supply. Surdam contends that the blockade was a powerful weapon that eventually ruined the Southern economy, costing few lives in combat. The Confederate cotton crop became nearly useless, cutting off the Confederacy's primary income source. Critical imports were scarce, and coastal trade largely ended as well. The blockade's success was not measured by the few ships that slipped through but by

18576-507: The infrastructure required to transport the trees from their point of origin to the shipyards. Shipbuilders were usually divided into different groups and had separate jobs. Some were responsible for fixing old ships; some were responsible for making the keel and some were responsible for building the helm. After 1477, the Ming government reversed its open maritime policies, enacting a series of isolationist policies in response to piracy . The policies, called Haijin (sea ban), lasted until

18748-545: The international press. By 1861, Union diplomats like Carl Schurz realized emphasizing the war against slavery was the Union's most effective moral asset in swaying European public opinion. Seward was concerned an overly radical case for reunification would distress European merchants with cotton interests; even so, he supported a widespread campaign of public diplomacy. U.S. minister to Britain Charles Francis Adams proved adept and convinced Britain not to challenge

18920-409: The intervening delay, but was refused on the basis that the wait had not been excessive. Shortly thereafter, Sneden declared himself insolvent, and ceded his shipyard to his partner Rowland, who pledged to settle the failed company's outstanding business. Having gained control of the shipyard, Rowland renamed it the Continental Iron Works. The waterworks contract would later be successfully completed by

19092-524: The introduction of outrigger canoe technology to non-Austronesian cultures in the East African coast. The ancient Chinese also built fluvial ramming vessels as in the Greco-Roman tradition of the trireme , although oar-steered ships in China lost favor very early on since it was in the 1st century China that the stern -mounted rudder was first developed. This was dually met with the introduction of

19264-485: The keel, the hull was made by overlapping nine strakes on either side with rivets fastening the oaken planks together. It could hold upwards of thirty men. Sometime around the 12th century, northern European ships began to be built with a straight sternpost , enabling the mounting of a rudder, which was much more durable than a steering oar held over the side. Development in the Middle Ages favored "round ships", with

19436-470: The latter half of the 19th century, providing great savings when compared with iron in cost and weight. Wood continued to be favored for the decks. During World War II , the need for cargo ships was so great that construction time for Liberty ships went from initially eight months or longer, down to weeks or even days. They employed production line and prefabrication techniques such as those used in shipyards today. The total number of dry-cargo ships built in

19608-475: The legislatures of the dissolution of ties to the Union. However, at least four—South Carolina, Mississippi, Georgia, and Texas —provided detailed reasons for their secession, all blaming the movement to abolish slavery and its influence over the North. Southern states believed that the Fugitive Slave Clause made slaveholding a constitutional right. These states agreed to form a new federal government,

19780-415: The manufacture of gun carriages , and for fitting out of merchant ships purchased by the Navy for war use. He also received a contract for the construction of mortar beds for Commander David Dixon Porter 's fleet of mortar schooners , which would later see action in the Battle of Forts Jackson and St. Philip . In September, New York engineer John Ericsson presented the Navy with a proposal to build

19952-508: The mid-1850s, in partnership with a young shipbuilder named E. S. Whitlock. In 1859, James L. Day, agent of the New Orleans & Mobile Mail Line and a repeat customer of Sneden's, requested that the shipbuilder construct an iron-hulled steamer for his company. Having no experience in the construction of iron hulls, Sneden took a young engineer named Thomas F. Rowland into temporary partnership in his firm, Samuel Sneden & Co., to assist in

20124-412: The mid-18th century and from the mid-19th century onwards. This was partly led by the shortage of "compass timber", the naturally curved timber that meant that shapes could be cut without weaknesses caused by cuts across the grain of the timber. Ultimately, whole ships were made of iron and, later, steel . The earliest known depictions (including paintings and models) of shallow-water sailing boats

20296-555: The most famous shipyards was Long Jiang Shipyard ( zh:龙江船厂 ), located in Nanjing near the Treasure Shipyard where the ocean-going ships were built. The shipbuilders could build 24 models of ships of varying sizes. Several types of ships were built for the voyages, including Shachuan (沙船), Fuchuan (福船) and Baochuan ( treasure ship ) (宝船). Zheng He's treasure ships were regarded as Shachuan types, mainly because they were made in

20468-472: The need to counter the Union's naval superiority, built or converted over 130 vessels, including 26 ironclads. Despite these efforts, Confederate ships were largely unsuccessful against Union ironclads. The Union Navy used timberclads, tinclads, and armored gunboats. Shipyards in Cairo, Illinois, and St. Louis built or modified steamboats . The Confederacy experimented with the submarine CSS  Hunley , which

20640-418: The new Confederacy sent delegates to Washington to negotiate a peace treaty. Lincoln rejected negotiations, because he claimed that the Confederacy was not a legitimate government and to make a treaty with it would recognize it as such. Lincoln instead attempted to negotiate directly with the governors of seceded states, whose administrations he continued to recognize. Complicating Lincoln's attempts to defuse

20812-419: The new company. The establishment of the Continental Iron Works in early 1861 coincided with the outbreak of the American Civil War , which began in April of that year. In May, Rowland traveled to Washington, D.C. , to present the Navy Department with conceptual plans for a screw-propelled ironclad with revolving gun turrets . His proposal was rejected as unfeasible, but he did manage to secure contracts for

20984-645: The north of it, while permitting it to the south. The Compromise would likely have prevented secession, but Lincoln and the Republicans rejected it. Lincoln stated that any compromise that would extend slavery would bring down the Union. A February peace conference met in Washington, proposing a solution similar the Compromise; it was rejected by Congress. The Republicans proposed the Corwin Amendment , an alternative, not to interfere with slavery where it existed, but

21156-421: The notion that a state had the right to nullify federal laws and even secede. On December 20, 1860, the convention unanimously voted to secede and adopted a secession declaration . It argued for states' rights for slave owners but complained about states' rights in the North in the form of resistance to the federal Fugitive Slave Act, claiming that Northern states were not fulfilling their obligations to assist in

21328-461: The oldest ships yet unearthed are known as the Abydos boats . These are a group of 14 ships discovered in Abydos that were constructed of wooden planks which were "sewn" together. Discovered by Egyptologist David O'Connor of New York University , woven straps were found to have been used to lash the planks together, and reeds or grass stuffed between the planks helped to seal the seams. Because

21500-419: The planking has defined the hull shape. Carvel construction then took over in the Mediterranean. Northern Europe used clinker construction , but with some flush-planked ship-building in, for instance, the bottom planking of cogs . The north-European and Mediterranean traditions merged in the late 15th century, with carvel construction being adopted in the North and the centre-line mounted rudder replacing

21672-477: The presidency of the firm passing to vice-president Warren E. Hill. Hill died in 1908, and Rowland's son, Thomas F. Rowland Jr., became president. Rowland Jr. retired in 1928, at which time the business was liquidated. The company's machine tools for the manufacture of corrugated boiler furnaces were purchased by the American Welding Company, after which, the defunct firm's site lay idle for some years. It

21844-458: The primary cause of disunion, it was disunion itself that sparked the war." Abraham Lincoln won the 1860 presidential election . Southern leaders feared Lincoln would stop slavery's expansion and put it on a course toward extinction. His victory triggered declarations of secession by seven slave states of the Deep South , all of whose riverfront or coastal economies were based on cotton that

22016-483: The process—and was only finally completed in 1896 at the Mare Island Navy Yard . In 1884–1885, the Continental Works built the ferryboats Atlantic and Brooklyn for New York's Union Ferry Company ; these were the first two steel-hulled ferryboats built in the United States. In 1876, the Continental Iron Works became a pioneer in welding technology when it successfully applied plate-welding techniques to

22188-416: The project. Some basic ironworking facilities, including a forge , punch and shears, were acquired by the firm, which in 1859–1861 completed three iron-hulled steamers, including that for Day's steamboat line. Seeking to further capitalize on its investment in ironworking equipment, Samuel Sneden & Co. submitted a bid in 1860 for the construction of a quarter-mile long, large-diameter iron pipeline across

22360-492: The quarter rudder of the Mediterranean. These changes broadly coincided with improvements in sailing rigs, with the three masted ship becoming common, with square sails on the fore and main masts, and a fore and aft sail on the mizzen. Ship-building then saw a steady improvement in design techniques and introduction of new materials. Iron was used for more than fastenings ( nails and bolts ) as structural components such as iron knees were introduced, with examples existing in

22532-416: The resilient and salt-resistant pandanus leaves. These sails allowed Austronesians to embark on long-distance voyaging. The ancient Champa of Vietnam also uniquely developed basket-hulled boats whose hulls were composed of woven and resin - caulked bamboo, either entirely or in conjunction with plank strakes . They range from small coracles (the o thúng ) to large ocean-going trading ships like

22704-454: The retirement of the founder's son. In 1851, New York shipbuilder Samuel Sneden relocated his shipyard from Manhattan to Greenpoint , becoming one of the first in his industry to do so. His new yard was located at the foot of West and Calyer Streets, just north of Bushwick Inlet . Over the next decade, Sneden would produce a substantial number of wooden- hulled steamboats and other vessels at this yard, both under his own name and, during

22876-414: The return of fugitive slaves. The "cotton states" of Mississippi , Florida , Alabama , Georgia , Louisiana , and Texas followed suit, seceding in January and February 1861. Among the ordinances of secession, those of Texas, Alabama, and Virginia mentioned the plight of the "slaveholding states" at the hands of Northern abolitionists. The rest made no mention of slavery but were brief announcements by

23048-547: The ship's construction. For the engines, he enlisted the services of his friend, Cornelius H. Delamater , proprietor of the Delamater Works, while for the turret, he subcontracted with the Novelty Iron Works —the only facility in the country then capable of bending its thick armor plates . For the hull, the Continental Iron Works, as one of the few New York-based companies with recent expertise in iron shipbuilding,

23220-450: The shipbuilder learned the techniques of shipbuilding from his family and is very likely to earn a higher status in the shipyard. Additionally, the shipbuilder had access to business networking that could help to find clients. If a shipbuilder entered the occupation through an apprenticeship, the shipbuilder was likely a farmer before he was hired as a shipbuilder, or he was previously an experienced shipbuilder. Many shipbuilders working in

23392-456: The ships are all buried together and near a mortuary belonging to Pharaoh Khasekhemwy , originally they were all thought to have belonged to him, but one of the 14 ships dates to 3000 BC, and the associated pottery jars buried with the vessels also suggest earlier dating. The ship dating to 3000 BC was about 75 feet (23 m) long and is now thought to perhaps have belonged to an earlier pharaoh. According to professor O'Connor,

23564-429: The ships built were financed by consortia of investors. These considerations led to the documentation of design and construction practices in what had previously been a secretive trade run by master shipwrights and ultimately led to the field of naval architecture , in which professional designers and draftsmen played an increasingly important role. Even so, construction techniques changed only very gradually. The ships of

23736-422: The shipyard were forced into the occupation. The ships built for Zheng He's voyages needed to be waterproof, solid, safe, and have ample room to carry large amounts of trading goods. Therefore, due to the highly commercialized society that was being encouraged by the expeditions, trades, and government policies, the shipbuilders needed to acquire the skills to build ships that fulfil these requirements. Shipbuilding

23908-433: The shipyards, the marine equipment manufacturers, and many related service and knowledge providers) grew as an important and strategic industry in a number of countries around the world. This importance stems from: Historically, the industry has suffered from the absence of global rules and a tendency towards ( state - supported ) over-investment due to the fact that shipyards offer a wide range of technologies, employ

24080-649: The site of Portus in Rome revealed inscriptions in a shipyard constructed during the reign of Trajan (98–117) that indicated the existence of a shipbuilders guild . Roughly at this time is the last migration wave of the Austronesian expansion , when the Polynesian islands spread over vast distances across the Pacific Ocean were being colonized by the (Austronesian) Polynesians from Island Melanesia using double-hulled voyaging catamarans . At its furthest extent, there

24252-567: The southwestern corner of Missouri (see Missouri secession ). Early in the war the Confederacy controlled southern Missouri through the Confederate government of Missouri but was driven out after 1862. In the resulting vacuum, the convention on secession reconvened and took power as the Unionist provisional government of Missouri. Kentucky did not secede, it declared itself neutral. When Confederate forces entered in September 1861, neutrality ended and

24424-526: The stalwart island Fort Sumter. Anderson's actions catapulted him to hero status in the North. An attempt to resupply the fort on January 9, 1861, failed and nearly started the war then, but an informal truce held. On March 5, Lincoln was informed the fort was low on supplies. Fort Sumter proved a key challenge to Lincoln's administration. Back-channel dealing by Seward with the Confederates undermined Lincoln's decision-making; Seward wanted to pull out. But

24596-446: The state reaffirmed its Union status while maintaining slavery. During an invasion by Confederate forces in 1861, Confederate sympathizers and delegates from 68 Kentucky counties organized the secession Russellville Convention, formed the shadow Confederate Government of Kentucky , inaugurated a governor, and Kentucky was admitted into the Confederacy on December 10, 1861. Its jurisdiction extended only as far as Confederate battle lines in

24768-478: The stronger flushed deck design derived from Indian designs, and the increasing use of iron reinforcement. The flushed deck originated from the Bengal rice ships, with Bengal being famous for its shipbuilding industry at the time. Iron was gradually adopted in ship construction, initially to provide stronger joints in a wooden hull e.g. as deck knees, hanging knees, knee riders and the other sharp joints, ones in which

24940-452: The substitute provision to select which man should go into the army and which should stay home. There was much evasion and resistance to the draft, especially in Catholic areas. The New York City draft riots in July 1863 involved Irish immigrants who had been signed up as citizens to swell the vote of the city's Democratic political machine , not realizing it made them liable for the draft. Of

25112-442: The ten-month Siege of Petersburg , gateway to the Confederate capital of Richmond . The Confederates abandoned Richmond, and on April 9, 1865, Lee surrendered to Grant following the Battle of Appomattox Court House , setting in motion the end of the war . Lincoln led the nation until he was shot by an assassin on April 14. By the end of the war, much of the South's infrastructure was destroyed. The Confederacy collapsed, slavery

25284-451: The thousands that never tried. European merchant ships could not get insurance and were too slow to evade the blockade, so they stopped calling at Confederate ports. To fight an offensive war, the Confederacy purchased arms in Britain and converted British-built ships into commerce raiders . The smuggling of 600,000 arms enabled the Confederacy to fight on for two more years, and the commerce raiders targeted U.S. Merchant Marine ships in

25456-549: The treasure shipyard in Nanjing. Shachuan , or 'sand-ships', are ships used primarily for inland transport. However, in recent years, some researchers agree that the treasure ships were more of the Fuchuan type. It is said in vol. 176 of San Guo Bei Meng Hui Bian (三朝北盟汇编) that ships made in Fujian are the best ones. Therefore, the best shipbuilders and laborers were brought from these places to support Zheng He's expedition. The shipyard

25628-531: The war began and, led by its president, Jefferson Davis , the Confederacy asserted control over a third of the U.S. population in eleven states. Four years of intense combat, mostly in the South, ensued. During 1861–1862 in the Western theater , the Union made permanent gains—though in the Eastern theater the conflict was inconclusive. The abolition of slavery became a Union war goal on January 1, 1863, when Lincoln issued

25800-430: The war created jobs for arms makers, ironworkers, and ships to transport weapons. Lincoln's administration initially struggled to appeal to European public opinion. At first, diplomats explained that the U.S. was not committed to ending slavery and emphasized legal arguments about the unconstitutionality of secession. Confederate representatives, however, focused on their struggle for liberty, commitment to free trade, and

25972-478: The war due to multiple factors: severe food shortages, failing railroads, loss of control over key rivers, foraging by Northern armies, and the seizure of animals and crops by Confederate forces. Historians agree the blockade was a major factor in ruining the Confederate economy; however, Wise argues blockade runners provided enough of a lifeline to allow Lee to continue fighting for additional months, thanks to supplies like 400,000 rifles, lead, blankets, and boots that

26144-437: The war, the company continued to produce buoys and furnaces, but increasingly turned to the manufacture of gas mains and large-diameter welded water pipes for the bulk of its business. The latter product had a number of advantages over riveted pipes, including smooth interior surfaces, lessening water friction, and reduced leakage. In 1907, Thomas F. Rowland, the company's founder and president since its inception in 1861, died,

26316-603: The waterline, the introduction of copper sheathing as a deterrent to shipworm and fouling, etc. In the early decades of the Industrial Revolution (1760 to 1825) western ship design remained largely based on its traditional pre-industrial designs and materials and yet greatly improved in safety as "the risk of being wrecked for Atlantic shipping fell by one-third, and of foundering by two thirds, reflecting improvements in seaworthiness and navigation respectively." The improvement in seaworthiness has been credited to adopting

26488-525: The world" within a few years. Some European observers at the time dismissed them as amateur and unprofessional, but historian John Keegan concluded that each outmatched the French, Prussian, and Russian armies, and without the Atlantic, could have threatened any of them with defeat. Unionism was strong in certain areas within the Confederacy. As many as 100,000 men living in states under Confederate control served in

26660-603: The world." The principal political battle leading to Southern secession was over whether slavery would expand into the Western territories destined to become states. Initially Congress had admitted new states into the Union in pairs, one slave and one free . This had kept a sectional balance in the Senate but not in the House of Representatives , as free states outstripped slave states in numbers of eligible voters. Thus, at mid-19th century,

26832-509: Was abolished, and four million enslaved black people were freed. The war-torn nation then entered the Reconstruction era in an attempt to rebuild the country, bring the former Confederate states back into the United States, and grant civil rights to freed slaves. The war is one of the most extensively studied and written about episodes in U.S. history . It remains the subject of cultural and historiographical debate . Of continuing interest

27004-429: Was an obvious choice, and a contract to build the ship was signed by Rowland and Ericsson on 25 October. The new ironclad, named USS  Monitor , was launched at the Continental Works in just 101 days (although Monitor was delivered a day later than the term specified in the contract, the Navy chose to waive any penalty). The ironclad was dispatched immediately after completion to Hampton Roads , Virginia , where

27176-433: Was cultivated by slave labor. Lincoln was not inaugurated until March 4, 1861, giving the South time to prepare for war during the winter of 1860–1861. Nationalists in the North and "Unionists" in the South refused to accept the declarations of secession. No foreign government ever recognized the Confederacy. The U.S. government, under President James Buchanan , refused to relinquish its forts that were in territory claimed by

27348-408: Was high because many soldiers were more concerned about the fate of their local area than the Southern cause. In the North, " bounty jumpers " enlisted to collect the generous bonus, deserted, then re-enlisted under a different name for a second bonus; 141 were caught and executed. From a tiny frontier force in 1860, the Union and Confederate armies grew into the "largest and most efficient armies in

27520-403: Was later partly occupied by a lumber yard and a fuel company. As of 2020, the site was again idle. The following table lists the iron-hulled ships built by Samuel Sneden & Co. from 1859 to 1861, when Rowland was a partner in the firm. Though not strictly speaking part of the output of the Continental Iron Works, they were built with the expertise of Rowland, at the yard that would later become

27692-405: Was made of bullion lost from mints. He stated that it would be US policy "to collect the duties and imposts"; "there will be no invasion, no using of force against or among the people anywhere" that would justify an armed revolution. His speech closed with a plea for restoration of the bonds of union, famously calling on "the mystic chords of memory" binding the two regions. The Davis government of

27864-566: Was marked by intense and frequent battles. Over four years, 237 named battles were fought, along with many smaller actions, often characterized by their bitter intensity and high casualties. Historian John Keegan described it as "one of the most ferocious wars ever fought," where, in many cases, the only target was the enemy's soldiers. As the Confederate states organized, the U.S. Army numbered 16,000, while Northern governors began mobilizing their militias. The Confederate Congress authorized up to 100,000 troops in February. By May, Jefferson Davis

28036-525: Was much more accomplished than had been thought and has described the distribution of clinker vs. carvel construction in Western Europe (see map [1] ). An insight into shipbuilding in the North Sea/Baltic areas of the early medieval period was found at Sutton Hoo , England, where a ship was buried with a chieftain. The ship was 26 metres (85 ft) long and 4.3 metres (14 ft) wide. Upward from

28208-505: Was not successful, and with the ironclad CSS  Virginia , rebuilt from the sunken Union ship Merrimack . On March 8, 1862, Virginia inflicted significant damage on the Union's wooden fleet, but the next day, the first Union ironclad, USS  Monitor , arrived to challenge it in the Chesapeake Bay . The resulting three-hour Battle of Hampton Roads was a draw, proving ironclads were effective warships. The Confederacy scuttled

28380-539: Was not the sole industry utilising Chinese lumber at that time; the new capital was being built in Beijing from approximately 1407 onwards, which required huge amounts of high-quality wood. These two ambitious projects commissioned by Emperor Yongle would have had enormous environmental and economic effects, even if the ships were half the dimensions given in the History of Ming . Considerable pressure would also have been placed on

28552-460: Was pushing for another 100,000 soldiers for one year or the duration, and the U.S. Congress responded in kind. In the first year of the war, both sides had more volunteers than they could effectively train and equip. After the initial enthusiasm faded, relying on young men who came of age each year was not enough. Both sides enacted draft laws (conscription) to encourage or force volunteering, though relatively few were drafted. The Confederacy passed

28724-637: Was the burgeoning gasworks industry, driven by the growing demand for gas lighting. Over the next few decades, the Continental Works would supply gas equipment to the industry throughout the Eastern United States, including gas mains , giant telescopic gas holders and complete gas plant installations. For one company alone, for example, the Consolidated Gas Company, the Continental Works built three gas plants in New York City, and supplied

28896-444: Was the first radical new design, being built entirely of wrought iron. Despite her success, and the great savings in cost and space provided by the iron hull, compared to a copper-sheathed counterpart, there remained problems with fouling due to the adherence of weeds and barnacles. As a result, composite construction remained the dominant approach where fast ships were required, with wooden timbers laid over an iron frame ( Cutty Sark

29068-418: Was to preserve the Union, a cause based on American nationalism . Background factors in the run up to the Civil War were partisan politics , abolitionism , nullification versus secession , Southern and Northern nationalism, expansionism , economics , and modernization in the antebellum period . As a panel of historians emphasized in 2011, "while slavery and its various and multifaceted discontents were

29240-525: Was too late. " King Cotton " was dead, as the South could export less than 10% of its cotton. The blockade shut down the ten Confederate seaports with railheads that moved almost all the cotton. By June 1861, warships were stationed off the principal Southern ports, and a year later nearly 300 ships were in service. The Confederates began the war short on military supplies, which the agrarian South could not produce. Northern arms manufacturers were restricted by an embargo, ending existing and future contracts with

29412-426: Was under the command of Ministry of Public Works . The shipbuilders had no control over their lives. The builders, commoner's doctors, cooks and errands had lowest social status. The shipbuilders were forced to move away from their hometown to the shipyards. There were two major ways to enter the shipbuilder occupation: family tradition, or apprenticeship. If a shipbuilder entered the occupation due to family tradition,

29584-464: Was unknown when the Chinese people started adopting Southeast Asian (Austronesian) shipbuilding techniques. They may have been started as early as the 8th century, but the development was gradual and the true ocean-going Chinese junks did not appear suddenly. The word "po" survived in Chinese long after, referring to the large ocean-going junks. In September 2011, archeological investigations done at
