138-530: The James River and Kanawha Canal was a partially built canal in Virginia intended to facilitate shipments of passengers and freight by water between the western counties of Virginia and the coast. Ultimately its towpath became the roadbed for a rail line following the same course. Encouraged by George Washington , the canal project was begun in 1785 as the James River Company, and later restarted under
276-534: A caisson of water in which boats float while being moved between two levels; and inclined planes where a caisson is hauled up a steep railway. To cross a stream, road or valley (where the delay caused by a flight of locks at either side would be unacceptable) the valley can be spanned by a navigable aqueduct – a famous example in Wales is the Pontcysyllte Aqueduct (now a UNESCO World Heritage Site ) across
414-504: A drainage divide atop a ridge , generally requiring an external water source above the highest elevation . The best-known example of such a canal is the Panama Canal . Many canals have been built at elevations, above valleys and other waterways. Canals with sources of water at a higher level can deliver water to a destination such as a city where water is needed. The Roman Empire 's aqueducts were such water supply canals. The term
552-415: A "cistern", or depressed area just downstream from the fall, to "cushion" the water by providing a deep pool for its kinetic energy to be diffused in. Vertical falls work for drops of up to 1.5 m in height, and for discharge of up to 15 cubic meters per second. The transport capacity of pack animals and carts is limited. A mule can carry an eighth-ton [250 pounds (113 kg)] maximum load over
690-533: A brief skirmish at Lexington, followed by the full-scale Battles of Lexington and Concord. British troops suffered around 300 casualties before withdrawing to Boston , which was then besieged by the militia. In May 1775, 4,500 British reinforcements arrived under Generals William Howe , John Burgoyne , and Sir Henry Clinton . On June 17, they seized the Charlestown Peninsula at the Battle of Bunker Hill ,
828-496: A canal has a series of dams and locks that create reservoirs of low speed current flow. These reservoirs are referred to as slack water levels , often just called levels . A canal can be called a navigation canal when it parallels a natural river and shares part of the latter's discharges and drainage basin , and leverages its resources by building dams and locks to increase and lengthen its stretches of slack water levels while staying in its valley . A canal can cut across
966-544: A civil war, since each state represented in Congress was engaged in a struggle with Britain, but also split between American Patriots and American Loyalists. Patriots generally supported independence from Britain and a new national union in Congress, while Loyalists remained faithful to British rule. Estimates of numbers vary, one suggestion being the population as a whole was split evenly between committed Patriots, committed Loyalists, and those who were indifferent. Others calculate
1104-413: A combination of the three, depending on available water and available path: Smaller transportation canals can carry barges or narrowboats , while ship canals allow seagoing ships to travel to an inland port (e.g., Manchester Ship Canal ), or from one sea or ocean to another (e.g., Caledonian Canal , Panama Canal ). At their simplest, canals consist of a trench filled with water. Depending on
1242-768: A customs vessel in the June 1772 Gaspee Affair , then came to a head in 1773. A banking crisis led to the near-collapse of the East India Company , which dominated the British economy; to support it, Parliament passed the Tea Act , giving it a trading monopoly in the Thirteen Colonies . Since most American tea was smuggled by the Dutch, the act was opposed by those who managed the illegal trade, while being seen as yet another attempt to impose
1380-542: A frontal assault in which they suffered over 1,000 casualties. Dismayed at the costly attack which had gained them little, Gage appealed to London for a larger army, but instead was replaced as commander by Howe. On June 14, 1775, Congress took control of Patriot forces outside Boston, and Congressional leader John Adams nominated Washington as commander-in-chief of the newly formed Continental Army . On June 16, Hancock officially proclaimed him "General and Commander in Chief of
1518-543: A journey measured in days and weeks, though much more for shorter distances and periods with appropriate rest. Besides, carts need roads. Transport over water is much more efficient and cost-effective for large cargoes. The oldest known canals were irrigation canals, built in Mesopotamia c. 4000 BC , in what is now Iraq . The Indus Valley civilization of ancient India ( c. 3000 BC ) had sophisticated irrigation and storage systems developed, including

#17330858475161656-450: A logistically challenging and dangerous operation. Meanwhile, the Hessians were involved in numerous clashes with small bands of Patriots and were often aroused by false alarms at night in the weeks before the actual Battle of Trenton . By Christmas they were tired, while a heavy snowstorm led their commander, Colonel Johann Rall , to assume no significant attack would occur. At daybreak on
1794-418: A long list of alleged violations of "English rights" committed by George III . This is also one of the first times that the colonies were referred to as "United States", rather than the more common United Colonies . On July 2, Congress voted for independence and published the declaration on July 4. At this point, the revolution ceased to be an internal dispute over trade and tax policies and had evolved into
1932-575: A rather low gradient for its time. The canal is still in use after renovation. In the Middle Ages , water transport was several times cheaper and faster than transport overland. Overland transport by animal drawn conveyances was used around settled areas, but unimproved roads required pack animal trains, usually of mules to carry any degree of mass, and while a mule could carry an eighth ton, it also needed teamsters to tend it and one man could only tend perhaps five mules, meaning overland bulk transport
2070-553: A rearguard. Howe met with a delegation from the Second Continental Congress at the September Staten Island Peace Conference , but it failed to conclude peace, largely because the British delegates only had the authority to offer pardons and could not recognize independence. On September 15, Howe seized control of New York City when the British landed at Kip's Bay and unsuccessfully engaged
2208-842: A riot started in Boston when the authorities seized the sloop Liberty on suspicion of smuggling. Tensions escalated further in March 1770 when British troops fired on rock-throwing civilians, killing five in what became known as the Boston Massacre . The Massacre coincided with the partial repeal of the Townshend Acts by the Tory-based North Ministry , which came to power in January 1770 and remained in office until 1781. North insisted on retaining duty on tea to enshrine Parliament's right to tax
2346-643: A second attack captured Fort Mifflin on November 16, while Fort Mercer was abandoned two days later when Cornwallis breached the walls. His supply lines secured, Howe tried to tempt Washington into giving battle, but after inconclusive skirmishing at the Battle of White Marsh from December 5 to 8, he withdrew to Philadelphia for the winter. On December 19, the Americans followed suit and entered winter quarters at Valley Forge ; while Washington's domestic opponents contrasted his lack of battlefield success with Gates' victory at Saratoga, foreign observers such as Frederick
2484-595: A threat to liberty in general. This led to increased sympathy for the Patriot cause locally, in the British Parliament, and in the London press. Throughout the 18th century, the elected lower houses in the colonial legislatures gradually wrested power from their governors. Dominated by smaller landowners and merchants, these assemblies now established ad-hoc provincial legislatures, effectively replacing royal control. With
2622-453: A uniform altitude. Other, generally later, canals took more direct routes requiring the use of various methods to deal with the change in level. Canals have various features to tackle the problem of water supply. In cases, like the Suez Canal, the canal is open to the sea. Where the canal is not at sea level, a number of approaches have been adopted. Taking water from existing rivers or springs
2760-422: Is a channel that cuts across a drainage divide , making a navigable channel connecting two different drainage basins . Both navigations and canals use engineered structures to improve navigation: Since they cut across drainage divides, canals are more difficult to construct and often need additional improvements, like viaducts and aqueducts to bridge waters over streams and roads, and ways to keep water in
2898-739: Is a historic lock and dam structure on south side of the James River near Gilmore Mills, Botetourt County, Virginia. There is a restored lock in the village of Big Island off the James River where it is crossed by the Blue Ridge Parkway. A visitor center is located in Amherst County just north of the bridge crossing the river. The canal lock is in Big Island on the Bedford County side of the James and

Much of the former James River and Kanawha Turnpike portage route through West Virginia is today the Midland Trail , a National Scenic Byway . Stock from the canal worth $ 20,000 was given to Liberty Hall Academy in Virginia's Shenandoah Valley by George Washington as an endowment. That gift prompted the renaming of the Academy to Washington College, which became today's Washington and Lee University in Lexington, Virginia . [REDACTED] Media related to James River and Kanawha Canal at Wikimedia Commons Canal Canals or artificial waterways are waterways or engineered channels built for drainage management (e.g. flood control and irrigation ) or for conveyancing water transport vehicles (e.g. water taxi ). They carry free, calm surface flow under atmospheric pressure , and can be thought of as artificial rivers . In most cases,

To break out of the limitations caused by river valleys, the first summit level canals were developed with the Grand Canal of China in 581–617 AD whilst in Europe the first, also using single locks, was the Stecknitz Canal in Germany in 1398. In

In the 5th century BC, Achaemenid king Xerxes I of Persia ordered the construction of the Xerxes Canal through the base of Mount Athos peninsula, Chalkidiki , northern Greece. It was constructed as part of his preparations for the Second Persian invasion of Greece , a part of the Greco-Persian Wars . It is one of the few monuments left by

A canal fall is constructed by cut and fill . It may be combined with a regulator, bridge, or other structure to save costs. There are various types of canal falls, based on their shape. One type is the ogee fall, where

The park is popular with fisherman and dog lovers, and is near the Ship Yard . The western entrance of the Richmond portion of the Canal lies near the village of Sabot in Goochland County while
3864-673: The Appalachian Mountains also avoided the cost of an expensive military occupation. The Royal Proclamation of 1763 was designed to achieve these aims by refocusing colonial expansion north into Nova Scotia and south into Florida , with the Mississippi River as the dividing line between British and Spanish possessions in America. Settlement was tightly restricted beyond the 1763 limits, and claims west of this line, including by Virginia and Massachusetts , were rescinded despite
4002-472: The Battle of Brandywine on September 11, then allowing him to withdraw in good order. After dispersing an American detachment at Paoli on September 20, Cornwallis occupied Philadelphia on September 26, with the main force of 9,000 under Howe based just to the north at Germantown . Washington attacked them on October 4, but was repulsed. To prevent Howe's forces in Philadelphia being resupplied by sea,
4140-506: The Battle of Sullivan's Island on June 28, 1776, but it failed. A shortage of gunpowder led Congress to authorize a naval expedition against the Bahamas to secure ordnance stored there. On March 3, 1776, an American squadron under the command of Esek Hopkins landed at the east end of Nassau and encountered minimal resistance at Fort Montagu . Hopkins' troops then marched on Fort Nassau . Hopkins had promised governor Montfort Browne and
4278-817: The Burning of Norfolk on January 1, 1776. The siege of Savage's Old Fields began on November 19 in South Carolina between Loyalist and Patriot militias, and the Loyalists were subsequently driven out of the colony in the Snow Campaign . Loyalists were recruited in North Carolina to reassert British rule in the South, but they were decisively defeated in the Battle of Moore's Creek Bridge . A British expedition sent to reconquer South Carolina launched an attack on Charleston in

In post-Roman Britain, the first early modern period canal built appears to have been the Exeter Canal , which was surveyed in 1563, and open in 1566. The oldest canal in the European settlements of North America, technically a mill race built for industrial purposes, is Mother Brook between the Boston, Massachusetts neighbourhoods of Dedham and Hyde Park connecting
5106-628: The Iroquois for their support, while US envoys urged them to remain neutral. Aware of Native American leanings toward the British and fearing an Anglo-Indian attack from Canada, Congress authorized a second invasion in April 1775. After the defeat at the Battle of Quebec on December 31, the Americans maintained a loose blockade of the city until they retreated on May 6, 1776. A second defeat at Trois-Rivières on June 8 ended operations in Quebec. British pursuit

A portion of the ancient canals has been renovated for the Salt River Project and now helps to supply the city's water. The Sinhalese constructed the 87 km (54 mi) Yodha Ela in 459 A.D. as a part of their extensive irrigation network which functioned in a way of a moving reservoir due to its single banking aspect to manage
5934-437: The Proclamation of Rebellion , issued on August 23 in response to the Battle at Bunker Hill , it ended hopes of a peaceful settlement. Backed by the Whigs, Parliament initially rejected the imposition of coercive measures by 170 votes, fearing an aggressive policy would drive the Americans towards independence. However, by the end of 1774 the collapse of British authority meant both Lord North and George III were convinced war
6072-470: The River Brue at Northover with Glastonbury Abbey , a distance of about 1.75 kilometres (1,900 yd). Its initial purpose is believed to be the transport of building stone for the abbey, but later it was used for delivering produce, including grain, wine and fish, from the abbey's outlying properties. It remained in use until at least the 14th century, but possibly as late as the mid-16th century. More lasting and of more economic impact were canals like

These were used primarily for irrigation and transport. Sunni Ali also attempted to construct a canal from the Niger River to Walata to facilitate conquest of the city but his progress was halted when he went to war with the Mossi Kingdoms . Around 1500–1800
6348-413: The Sugar Act and Stamp Act , which imposed additional taxes on the colonies to pay for defending the western frontier. In July 1765, the Whigs formed the First Rockingham ministry , which repealed the Stamp Act and reduced tax on foreign molasses to help the New England economy, but re-asserted Parliamentary authority in the Declaratory Act . However, this did little to end the discontent; in 1768,

Despite some initial success, British general Cornwallis was besieged by a Franco-American force in Yorktown in September and October 1781. Cornwallis was forced to surrender in October. The British wars with France and Spain continued for another two years, but fighting largely ceased in North America. In
6624-520: The colonial legislatures agreed on the boundaries but disagreed on where to set them. Many settlers resented the restrictions entirely, and enforcement required permanent garrisons along the frontier, which led to increasingly bitter disputes over who should pay for them. Although directly administered by the Crown , acting through a local governor, the colonies were largely governed by native-born property owners. While external affairs were managed by London, colonial militia were funded locally but with
6762-453: The reservoirs built at Girnar in 3000 BC. This is the first time that such planned civil project had taken place in the ancient world. In Egypt , canals date back at least to the time of Pepi I Meryre (reigned 2332–2283 BC), who ordered a canal built to bypass the cataract on the Nile near Aswan . In ancient China , large canals for river transport were established as far back as the Spring and Autumn period (8th–5th centuries BC),

Taking boats through these used large amounts of water leading to conflicts with watermill owners and to correct this, the pound or chamber lock first appeared, in the 10th century in China and in Europe in 1373 in Vreeswijk , Netherlands. Another important development was the mitre gate , which was, it

Flash locks were only practical where there was plenty of water available. Locks use a lot of water, so builders have adopted other approaches for situations where little water is available. These include boat lifts , such as the Falkirk Wheel , which use

The Battle of Trenton restored the American army's morale, reinvigorated the Patriot cause, and dispelled their fear of what they regarded as Hessian "mercenaries". A British attempt to retake Trenton was repulsed at Assunpink Creek on January 2; during

Popular support wavered, and morale declined. On December 20, 1776, the Continental Congress abandoned the revolutionary capital of Philadelphia and moved to Baltimore , where it remained until February 27, 1777. Loyalist activity surged in
7590-526: The Americans at the Battle of Harlem Heights the following day. On October 18, Howe failed to encircle the Americans at the Battle of Pell's Point , and the Americans withdrew. Howe declined to close with Washington's army on October 28 at the Battle of White Plains , and instead attacked a hill that was of no strategic value. Washington's retreat isolated his remaining forces and the British captured Fort Washington on November 16. The British victory there amounted to Washington's most disastrous defeat with
7728-407: The Canadians. In Virginia, Dunmore's Proclamation on November 7, 1775, promised freedom to any slaves who fled their Patriot masters and agreed to fight for the Crown. British forces were defeated at Great Bridge on December 9 and took refuge on British ships anchored near Norfolk. When the Third Virginia Convention refused to disband its militia or accept martial law, Lord Dunmore ordered
7866-584: The Colonial Secretary Lord Germain , proposing a limited offensive against Philadelphia, while a second force moved down the Hudson from Canada. Burgoyne supplied several alternatives, all of which gave him responsibility for the offensive, with Howe remaining on the defensive. The option selected required him to lead the main force south from Montreal down the Hudson Valley, while a detachment under Barry St. Leger moved east from Lake Ontario. The two would meet at Albany , leaving Howe to decide whether to join them. Reasonable in principle, this did not account for

Throughout the war, Washington spent more than 10 percent of his total military funds on military intelligence . Washington split the Continental Army into positions on Manhattan and across the East River in western Long Island. On August 27 at the Battle of Long Island , Howe outflanked Washington and forced him back to Brooklyn Heights , but he did not attempt to encircle Washington's forces. Through

Over the winter, poor conditions, supply problems and low morale resulted in 2,000 deaths, with another 3,000 unfit for duty due to lack of shoes. However, Baron Friedrich Wilhelm von Steuben took the opportunity to introduce Prussian Army drill and infantry tactics to "model companies" in each Continental Army regiment, who then instructed their home units. Despite Valley Forge being only twenty miles away, Howe made no effort to attack their camp, an action some critics argue could have ended
8418-413: The James River Company was formed, with former Revolutionary War Commander in Chief George Washington as honorary president, to build locks around the falls at Richmond. By then, Washington was quite busy with the affairs of the new nation, in 1789 being elected its first president. Promoted by such men as George Washington, Edmund Randolph , and John Marshall , the James River Company opened in 1790 as

His preference was the James, as the Potomac led to rivers in land disputed with Pennsylvania and would be equally helpful to Maryland . The James could be aligned with the Kanawha River (in what is now West Virginia ), and would best serve only Virginia, which was his priority. In 1785,

This slowed Burgoyne's progress and forced him to send out large foraging expeditions; on one of these, more than 700 British troops were captured at the Battle of Bennington on August 16. St Leger moved east and besieged Fort Stanwix ; despite defeating an American relief force at the Battle of Oriskany on August 6, he was abandoned by his Indian allies and withdrew to Quebec on August 22. Now isolated and outnumbered by Gates, Burgoyne continued onto Albany rather than retreating to Fort Ticonderoga, reaching Saratoga on September 13. He asked Clinton for support while constructing defenses around
9936-638: The army of the United Colonies." He assumed command on July 3, preferring to fortify Dorchester Heights outside Boston rather than assaulting it. In early March 1776, Colonel Henry Knox arrived with heavy artillery acquired in the Capture of Fort Ticonderoga . Under cover of darkness, on March 5, Washington placed these on Dorchester Heights, from where they could fire on the town and British ships in Boston Harbor. Fearing another Bunker Hill, Howe evacuated
10074-558: The base for American naval operations. After regrouping at Halifax in Nova Scotia, Howe set sail for New York in June 1776 and began landing troops on Staten Island near the entrance to New York Harbor on July 2. The Americans rejected Howe's informal attempt to negotiate peace on July 30; Washington knew that an attack on the city was imminent and realized that he needed advance information to deal with disciplined British regular troops. On August 12, 1776, Patriot Thomas Knowlton

However, on February 9 Parliament declared Massachusetts to be in rebellion and instituted a blockade of the colony. In July, the Restraining Acts limited colonial trade with the British West Indies and Britain and barred New England ships from the Newfoundland cod fisheries . The tension led to a scramble for control of militia stores, which each assembly

Burgoyne capitulated on October 17; around 6,222 soldiers, including German forces commanded by General Friedrich Adolf Riedesel , surrendered their arms before being taken to Boston, where they were to be transported to England. After securing additional supplies, Howe made another attempt on Philadelphia by landing his troops in Chesapeake Bay on August 24. He now compounded failure to support Burgoyne by missing repeated opportunities to destroy his opponent, defeating Washington at
10488-520: The canal as a far more productive mode of transportation. After the American Civil War funds for resuming construction were unavailable from either the war-torn Commonwealth or private sources and the project did poorly against railroad competition, finally succumbing to damage done by massive flooding in 1877. In the end its right-of-way was bought and the canal was largely dismantled by the new Richmond and Alleghany Railroad , which laid tracks on
10626-619: The canal incurred during the conflict was never completely repaired. By the time the Chesapeake and Ohio Railway was built through to the Ohio River in 1873, the canal's fate was clear. The James River and Kanawha Canal Company was authorized in 1876 to build the Buchanan and Clifton Forge Railway to connect the westernmost point of the canal with the C&;O. The Virginia General Assembly, in 1878, gave
10764-436: The canal pressure with the influx of water. It was also designed as an elongated reservoir passing through traps creating 66 mini catchments as it flows from Kala Wewa to Thissa Wawa . The canal was not designed for the quick conveying of water from Kala Wewa to Thissa Wawa but to create a mass of water between the two reservoirs, which would in turn provided for agriculture and the use of humans and animals. They also achieved
10902-418: The canal to form a dam. They are generally placed in pre-existing grooves in the canal bank. On more modern canals, "guard locks" or gates were sometimes placed to allow a section of the canal to be quickly closed off, either for maintenance, or to prevent a major loss of water due to a canal breach. A canal fall , or canal drop, is a vertical drop in the canal bed. These are built when the natural ground slope
11040-462: The canal. Where large amounts of goods are loaded or unloaded such as at the end of a canal, a canal basin may be built. This would normally be a section of water wider than the general canal. In some cases, the canal basins contain wharfs and cranes to assist with movement of goods. When a section of the canal needs to be sealed off so it can be drained for maintenance stop planks are frequently used. These consist of planks of wood placed across
11178-595: The canal. After many of the original Irish laborers died of hypothermia, they were replaced by enslaved Africans hired from plantation owners who lived near the route of the canal. After work stalled for a number of years the canal company went broke and gave up. In 1820, the Commonwealth of Virginia took control of the project and with state funds provided through the Virginia Board of Public Works resumed construction. Work stalled yet again, then resumed in 1835 under
11316-463: The channel. There are two broad types of canal: Historically, canals were of immense importance to commerce and the development, growth and vitality of a civilization. In 1855 the Lehigh Canal carried over 1.2 million tons of anthracite coal; by the 1930s the company which built and operated it for over a century ceased operation. The few canals still in operation in our modern age are a fraction of
11454-515: The city on March 17 without further loss and sailed to Halifax, Nova Scotia , while Washington moved south to New York City. Beginning in August 1775, American privateers raided towns in Nova Scotia, including Saint John , Charlottetown , and Yarmouth . In 1776, John Paul Jones and Jonathan Eddy attacked Canso and Fort Cumberland respectively. British officials in Quebec began negotiating with
11592-430: The civilian inhabitants that their lives and property would not be in any danger if they offered no resistance; they complied. Hopkins captured large stores of powder and other munitions that was so great he had to impress an extra ship in the harbor to transport the supplies back home, when he departed on March 17. A month later, after a brief skirmish with HMS Glasgow , they returned to New London, Connecticut ,
11730-569: The colonies; the amount was minor, but ignored the fact it was that very principle Americans found objectionable. In April 1772, colonialists staged the first American tax revolt in Weare , New Hampshire against the British royal authority later referred to as the Pine Tree Riot . This occurrence would later inspire the design of the Pine Tree Flag . Tensions escalated following the destruction of
11868-546: The committee shared information and built alliances through secret correspondence, as well as employing secret agents in Europe to gather intelligence, conduct undercover operations, analyze foreign publications, and initiate Patriot propaganda campaigns. Paine served as secretary, while Benjamin Franklin and Silas Deane , sent to France to recruit military engineers, were instrumental in securing French aid in Paris. The Revolutionary War included two principal campaign theaters within
12006-399: The drop follows an s-shaped curve to create a smooth transition and reduce turbulence . However, this smooth transition does not dissipate the water's kinetic energy, which leads to heavy scouring. As a result, the canal needs to be reinforced with concrete or masonry to protect it from eroding. Another type of canal fall is the vertical fall, which is "simple and economical". These feature
12144-518: The eastern lies in the city near the Richmond Deepwater Terminal . Sufficient waterflow appears to be provided by Bosher Dam , an 1835 structure located on the western side of the city. The Lock-Keeper's House is a historic home located near Cedar Point, Goochland County, Virginia. It was built about 1836 to serve Lock Number 7 and is the last remaining lock-keeper's house of the James River and Kanawha Canal system. Varney's Falls Dam
12282-527: The ending of the French threat in 1763, the legislatures expected less taxation, not more. At the same time, the huge debt incurred by the Seven Years' War and demands from British taxpayers for cuts in government expenditure meant Parliament expected the colonies to fund their own defense. The new taxes levied on subjects in the colonies proved highly burdensome in colonies such as North Carolina , particularly for
12420-663: The exception of Georgia , twelve colonies sent representatives to the First Continental Congress to agree on a unified response to the crisis. Many of the delegates feared that a boycott would result in war and sent a Petition to the King calling for the repeal of the Intolerable Acts. After some debate, on September 17, 1774, Congress endorsed the Massachusetts Suffolk Resolves and on October 20 passed
12558-513: The exception of a minor skirmishing between the two armies which continued until March, Howe made no attempt to attack the Americans. The 1776 campaign demonstrated that regaining New England would be a prolonged affair, which led to a change in British strategy to isolating the north by taking control of the Hudson River , allowing them to focus on the south where Loyalist support was believed to be substantial. In December 1776, Howe wrote to
12696-548: The face of enemy fire. The successes led to predictions that the British could win within a year. The British established winter quarters in the New York City area and anticipated renewed campaigning the following spring. On the night of December 25–26, 1776, Washington crossed the Delaware River , leading a column of Continental Army troops from today's Bucks County, Pennsylvania , to today's Mercer County, New Jersey , in
12834-582: The fact that each colony argued that their boundaries extended from the Atlantic Ocean to the Pacific Ocean . The vast exchange of territory ultimately destabilized existing alliances and trade networks between settlers and Indians in the west, while it proved impossible to prevent encroachment beyond the Proclamation Line. With the exception of Virginia and others deprived of rights to western lands,
12972-544: The first commercial canal in the United States. Stretching from Richmond, Virginia to Westham, Virginia and paralleling the James for 7 miles (11 km), it supplemented existing bateaux transportation on the James River. These flat-bottomed boats floated down the James to Richmond laden with tobacco hogsheads and returned with French and English imports, furniture, dishes, and clothing. In addition to bateaux, many canal boats were packets , which drew more water than
13110-648: The first summit level canal to use pound locks in Europe was the Briare Canal connecting the Loire and Seine (1642), followed by the more ambitious Canal du Midi (1683) connecting the Atlantic to the Mediterranean. This included a staircase of 8 locks at Béziers , a 157 metres (515 ft) tunnel, and three major aqueducts. Canal building progressed steadily in Germany in the 17th and 18th centuries with three great rivers,
13248-564: The former towpath. The R&A became part of the Chesapeake and Ohio Railway in the 1890s, which developed much of the former canal route into an important line for West Virginia bituminous coal headed eastbound for the Peninsula Extension to reach the Hampton Roads coal piers at Newport News for worldwide export aboard large colliers . The James River and Kanawha Canal was a project first proposed by George Washington when he
13386-456: The freedom to make deliveries well away from rail lined road beds or ditches in the dirt which could not operate in the winter. The longest extant canal today, the Grand Canal in northern China, still remains in heavy use, especially the portion south of the Yellow River . It stretches from Beijing to Hangzhou at 1,794 kilometres (1,115 miles). Canals are built in one of three ways, or
13524-725: The higher waters of the Charles River and the mouth of the Neponset River and the sea. It was constructed in 1639 to provide water power for mills. In Russia, the Volga–Baltic Waterway , a nationwide canal system connecting the Baltic Sea and Caspian Sea via the Neva and Volga rivers, was opened in 1718. American Revolutionary War American and allied victory Great Britain cedes generally, all mainland territories east of
13662-535: The load were carried by a barge on a waterway, then up to 30 tons could be drawn by the same horse. — technology historian Ronald W. Clark referring to transport realities before the industrial revolution and the Canal age . Hohokam was a society in the North American Southwest in what is now part of Arizona , United States, and Sonora , Mexico. Their irrigation systems supported the largest population in
13800-475: The logistical difficulties involved and Burgoyne erroneously assumed Howe would remain on the defensive; Germain's failure to make this clear meant he opted to attack Philadelphia instead. Burgoyne set out on June 14, 1777, with a mixed force of British regulars, professional German soldiers and Canadian militia, and captured Fort Ticonderoga on July 5. As General Horatio Gates retreated, his troops blocked roads, destroyed bridges, dammed streams, and stripped
13938-472: The longest canal in the world today and the oldest extant one. It is 1,794 kilometres (1,115 mi) long and was built to carry the Emperor Yang Guang between Zhuodu ( Beijing ) and Yuhang ( Hangzhou ). The project began in 605 and was completed in 609, although much of the work combined older canals, the oldest section of the canal existing since at least 486 BC. Even in its narrowest urban sections it
14076-523: The longest one of that period being the Hong Gou (Canal of the Wild Geese), which according to the ancient historian Sima Qian connected the old states of Song, Zhang, Chen, Cai, Cao, and Wei. The Caoyun System of canals was essential for imperial taxation, which was largely assessed in kind and involved enormous shipments of rice and other grains. By far the longest canal was the Grand Canal of China , still
14214-498: The loss of 3,000 prisoners. The remaining American regiments on Long Island fell back four days later. General Henry Clinton wanted to pursue Washington's disorganized army, but he was first required to commit 6,000 troops to capture Newport, Rhode Island , to secure the Loyalist port. General Charles Cornwallis pursued Washington, but Howe ordered him to halt. The outlook following the defeat at Fort Washington appeared bleak for
14352-632: The major highways of commerce. Early developments along the east coast of the colonies tended to end at the Fall Line (the head of navigation ) of the rivers that emptied into its great bays (e.g., the Delaware and the Chesapeake ). Such early communities in Virginia included what we now know as Alexandria on the Potomac River , Fredericksburg on the Rappahannock River , Richmond and Lynchburg on
14490-570: The new James River and Kanawha Company, with Judge Benjamin Wright as Chief Engineer. He was assisted by his son Simon Wright , Charles Ellet Jr. , and Daniel Livermore . By 1840, the canal was completed to Lynchburg . Service was inaugurated by William Henry Harrison who was elected president that same year. In 1847, Walter W. Gwynn was hired as Chief Engineer, with Edward Lorraine as his assistant. The canal eventually extended 196.5 miles (316 km) west of Richmond to Buchanan by 1851. There,
14628-467: The night of August 28, Knox bombarded the British. Knowing they were up against overwhelming odds, Washington ordered the assembly of a war council on August 29; all agreed to retreat to Manhattan. Washington quickly had his troops assembled and ferried them across the East River to Manhattan on flat-bottomed freight boats without any losses in men or ordnance, leaving General Thomas Mifflin 's regiments as
14766-440: The night, Washington outmaneuvered Cornwallis, then defeated his rearguard in the Battle of Princeton the following day. The two victories helped convince the French that the Americans were worthy military allies. After his success at Princeton, Washington entered winter quarters at Morristown, New Jersey , where he remained until May and received Congressional direction to inoculate all Patriot troops against smallpox . With
14904-506: The numbers that once fueled and enabled economic growth, indeed were practically a prerequisite to further urbanization and industrialization. For the movement of bulk raw materials such as coal and ores are difficult and marginally affordable without water transport. Such raw materials fueled the industrial developments and new metallurgy resulting of the spiral of increasing mechanization during 17th–20th century, leading to new research disciplines, new industries and economies of scale, raising
15042-524: The petition was immediately followed by the Declaration of the Causes and Necessity of Taking Up Arms , Colonial Secretary Lord Dartmouth viewed the offer as insincere and refused to present the petition to the king. Although constitutionally correct, since George could not oppose his own government, it disappointed those Americans who hoped he would mediate in the dispute, while the hostility of his language annoyed even Loyalist members of Congress. Combined with
15180-467: The pioneer railroads were combined under the Chesapeake and Ohio. Today, CSX trains loaded with coal from the mountains follow the old canal route, much of it at a gentler "water level" grade, headed to port at Newport News at Hampton Roads. The Buckingham Branch Railroad , a short-line railroad , has a lease to operate the original C&O alignment over the former Virginia Central Railroad , including
15318-462: The plan was to link it to the James River and Kanawha Turnpike to provide passage through the most rugged portions of the mountains. The goal was to reach the Kanawha River at its head of navigation, about 30 miles (50 km) east of today's Charleston, West Virginia . The portage necessary made competition with railroads along the same route a real threat. Construction of a planned railroad there
15456-552: The poorer classes, and quickly became a source of much discontent. The 1763 to 1765 Grenville ministry instructed the Royal Navy to cease trading smuggled goods and enforce customs duties levied in American ports. The most important was the 1733 Molasses Act ; routinely ignored before 1763, it had a significant economic impact since 85% of New England rum exports were manufactured from imported molasses. These measures were followed by
15594-582: The pre-railroad days of the industrial revolution, water transport was the gold standard of fast transportation. The first artificial canal in Western Europe was the Fossa Carolina built at the end of the 8th century under personal supervision of Charlemagne . In Britain, the Glastonbury Canal is believed to be the first post-Roman canal and was built in the middle of the 10th century to link
15732-557: The principal instigators of the rebellion. The operation was to begin around midnight on April 19, in the hope of completing it before the American Patriots could respond. However, Paul Revere learned of the plan and notified Captain Parker , commander of the Concord militia, who prepared to resist. The first action of the war, commonly referred to as the shot heard round the world , was
15870-621: The principle of taxation by Parliament. In December 1773, a group called the Sons of Liberty disguised as Mohawk natives dumped 342 crates of tea into the Boston Harbor , an event later known as the Boston Tea Party . The British Parliament responded by passing the so-called Intolerable Acts , aimed specifically at Massachusetts, although many colonists and members of the Whig opposition considered them
16008-504: The resulting Battles of Lexington and Concord in April 1775 ignited the war. In June, the Second Continental Congress formalized Patriot militias into the Continental Army and appointed Washington its commander-in-chief. The British Parliament declared the colonies to be in a state of rebellion in August 1775. The stakes of the war were formalized with passage of the Lee Resolution by the Congress in Philadelphia on July 2, 1776, and
16146-551: The smaller bateaux. Mules and horses pulled the packets along the towpaths. Locks were necessary at points where the river had rapids. The American Revolutionary War and the War of 1812 each slowed construction. Work was slow, expensive, and very labor-intensive through the rocky terrain of Virginia's Piedmont region, a transitional area between the sandy coastal plain and the mountains. The early congregation of St. Peters Church in Richmond consisted mostly of Irish immigrants who worked on
16284-468: The split as 40% Patriot, 40% neutral, 20% Loyalist, but with considerable regional variations. At the onset of the war, the Second Continental Congress realized defeating Britain required foreign alliances and intelligence-gathering. The Committee of Secret Correspondence was formed for "the sole purpose of corresponding with our friends in Great Britain and other parts of the world". From 1775 to 1776,
16422-480: The standard of living for any industrialized society. Most ship canals today primarily service bulk cargo and large ship transportation industries, whereas the once critical smaller inland waterways conceived and engineered as boat and barge canals have largely been supplanted and filled in, abandoned and left to deteriorate, or kept in service and staffed by state employees, where dams and locks are maintained for flood control or pleasure boating. Their replacement
16560-495: The town. Morale among his troops rapidly declined, and an unsuccessful attempt to break past Gates at the Battle of Freeman Farms on September 19 resulted in 600 British casualties. When Clinton advised he could not reach them, Burgoyne's subordinates advised retreat; a reconnaissance in force on October 7 was repulsed by Gates at the Battle of Bemis Heights , forcing them back into Saratoga with heavy losses. By October 11, all hope of escape had vanished; persistent rain reduced
16698-499: The unanimous ratification of the Declaration of Independence two days later, on July 4, 1776. After a successful siege , Washington's forces drove the British Army out of Boston in March 1776, and British commander in chief William Howe responded by launching the New York and New Jersey campaign . Howe captured New York City in November. Washington responded by clandestinely crossing
16836-556: The valley of the River Dee . Another option for dealing with hills is to tunnel through them. An example of this approach is the Harecastle Tunnel on the Trent and Mersey Canal . Tunnels are only practical for smaller canals. Some canals attempted to keep changes in level down to a minimum. These canals known as contour canals would take longer, winding routes, along which the land was
16974-428: The wake of the American defeat, especially in New York state . In London, news of the victorious Long Island campaign was well received with festivities held in the capital. Public support reached a peak. Strategic deficiencies among Patriot forces were evident: Washington divided a numerically weaker army in the face of a stronger one, his inexperienced staff misread the military situation, and American troops fled in
17112-701: The way. Visitors can also visit the Three-Mile Locks at Pump House Park, located behind the Carillon in William Byrd Park . This park is located three 3 miles (5 km) upstream from the canal's turning basin. It contains parts of the old 18th century locks, lockkeeper's house, the City's historic 1883 water pumping station originally called the New Pump-House , and its replacement, the 1924 pumping station. The City
17250-619: The wider global conflict known as the Seven Years' War , ended with the 1763 Peace of Paris , which expelled France from their possessions in New France . Acquisition of territories in Atlantic Canada and West Florida , inhabited largely by French and Spanish-speaking Catholics , led British authorities to consolidate their hold by populating them with English-speaking settlers. Preventing conflict between settlers and Indian tribes west of
17388-573: Was a viable possibility. France signed a commercial agreement with the rebels, followed by a Treaty of Alliance in February 1778. In 1779, the Sullivan Expedition undertook a scorched earth campaign against the Iroquois who were largely allied with the British. Indian raids on the American frontier, however, continued to be a problem. Also, in 1779, Spain allied with France against Great Britain in
17526-513: Was a young man surveying the mountains of western Virginia, which at the time consisted of what is today West Virginia , Kentucky , and to the north bank of the Ohio river. He was searching for a way to open a water route to the West. He believed that was the key to helping Virginia become an economic powerhouse in what would emerge as the United States quite a few years later. In those times, waterways were
17664-466: Was also expensive, as men expect compensation in the form of wages, room and board. This was because long-haul roads were unpaved, more often than not too narrow for carts, much less wagons, and in poor condition, wending their way through forests, marshy or muddy quagmires as often as unimproved but dry footing. In that era, as today, greater cargoes, especially bulk goods and raw materials , could be transported by ship far more economically than by land; in
17802-458: Was an option in some cases, sometimes supplemented by other methods to deal with seasonal variations in flow. Where such sources were unavailable, reservoirs – either separate from the canal or built into its course – and back pumping were used to provide the required water. In other cases, water pumped from mines was used to feed the canal. In certain cases, extensive "feeder canals" were built to bring water from sources located far from
17940-485: Was delayed by the American Civil War . However, both war damage and interruption in the flow of commerce along the canal did great harm to it. Railroads began to emerge as a more efficient form of transportation in the 1830s, midway in the canal's construction. In spite of the appointment of former Confederate general Armistead Lindsay Long as Chief Engineer following his service in the Civil War (1861–1865), damage which
18078-407: Was gradual, beginning first in the United States in the mid-1850s where canal shipping was first augmented by, then began being replaced by using much faster , less geographically constrained & limited, and generally cheaper to maintain railways . By the early 1880s, canals which had little ability to economically compete with rail transport, were off the map. In the next couple of decades, coal
18216-424: Was increasingly diminished as the heating fuel of choice by oil, and growth of coal shipments leveled off. Later, after World War I when motor-trucks came into their own, the last small U.S. barge canals saw a steady decline in cargo ton-miles alongside many railways, the flexibility and steep slope climbing capability of lorries taking over cargo hauling increasingly as road networks were improved, and which also had
18354-541: Was inevitable. After Boston, Gage halted operations and awaited reinforcements; the Irish Parliament approved the recruitment of new regiments, while allowing Catholics to enlist for the first time. Britain also signed a series of treaties with German states to supply additional troops . Within a year, it had an army of over 32,000 men in America, the largest ever sent outside Europe at the time. The employment of German soldiers against people viewed as British citizens
18492-574: Was initially blocked by American naval vessels on Lake Champlain until victory at Valcour Island on October 11 forced the Americans to withdraw to Fort Ticonderoga , while in December an uprising in Nova Scotia sponsored by Massachusetts was defeated at Fort Cumberland . These failures impacted public support for the Patriot cause, and aggressive anti-Loyalist policies in the New England colonies alienated
18630-421: Was legally obliged to maintain for defense. On April 19, a British attempt to secure the Concord arsenal culminated in the Battles of Lexington and Concord , which began the Revolutionary War. After the Patriot victory at Concord, moderates in Congress led by John Dickinson drafted the Olive Branch Petition , offering to accept royal authority in return for George III mediating in the dispute. However, since
18768-426: Was once used to describe linear features seen on the surface of Mars , Martian canals , an optical illusion. A navigation is a series of channels that run roughly parallel to the valley and stream bed of an unimproved river. A navigation always shares the drainage basin of the river. A vessel uses the calm parts of the river itself as well as improvements, traversing the same changes in height. A true canal
18906-411: Was opposed by many in Parliament and by the colonial assemblies; combined with the lack of activity by Gage, opposition to the use of foreign troops allowed the Patriots to take control of the legislatures. Support for independence was boosted by Thomas Paine 's pamphlet Common Sense , which was published on January 10, 1776, and argued for American self-government and was widely reprinted. To draft
19044-414: Was ordered to form an elite group for reconnaissance and secret missions. Knowlton's Rangers , which included Nathan Hale , became the Army's first intelligence unit. When Washington was driven off Long Island , he soon realized that he would need to professionalize military intelligence. With aid from Benjamin Tallmadge , Washington launched the six-man Culper spy ring . The efforts of Washington and
