USS Enterprise was a Continental Army sloop-of-war that served in Lake Champlain during the American Revolutionary War. She was the first of a long and prestigious line of ships of the United States or by the combatant forces of the U.S. Revolutionary War to bear the name Enterprise.
Enterprise was originally a British supply sloop named George, built at St. Johns (now Saint-Jean-sur-Richelieu) in Quebec, Canada.
In May 1775, a small American force under Colonel Benedict Arnold sailed up the Richelieu River on the recently captured . At 07:00 on 18 May, Arnold and 35 raiders captured the fort and shipyards at St. Johns, along with the newly launched George, with no loss of life. The unlaunched schooner was also at the shipyard, and would be captured by the Americans later that year. Two hours later Arnold's raiders left with the newly captured sloop, which was later armed with 12 guns and renamed Enterprise.
See main article: Siege of Fort St. Jean. Enterprise was, at first, the most significant warship in the Lake Champlain squadron – which was charged with maintaining American control of the lake early in the war – and at times she acted as flagship for Colonel Arnold. Control of Lake Champlain and the adjoining Hudson River would have enabled the British to cut off vital supply routes between New England and the other colonies, and it would have allowed British troops to cross and attack Albany.
On 28 August 1775, Enterprise and other vessels embarked with more than 1,000 troops as part of an expedition against St. Johns, Montreal, and Quebec. Though St. Johns and Montreal were captured, and Quebec was besieged, the arrival of strong British reinforcements forced the Americans to withdraw from Canada in the spring of 1776. Enterprise and the other craft sailed to Île aux Noix in the Richelieu River, where they waited while Arnold directed the building of a fleet at Fort Ticonderoga and Skenesboro (now Whitehall).
See main article: Battle of Valcour Island. The battle was finally joined in the Battle of Valcour Island on 11 October 1776 at Valcour Island, near Plattsburgh, New York, a site of Arnold's choosing. Markedly inferior in firepower, much of Arnold's fleet was sunk or damaged by nightfall. However, he managed to slip the remaining ships, including Enterprise, past the British fleet that night towards Fort Crown Point. A running battle took place over the next two days, and resulted in the loss of all but five of the American ships. Enterprise and four others escaped to Crown Point, then sailed on to Ticonderoga.
Although a tactical defeat, the battle was a strategic victory for the Americans. Arnold and his little fleet had disrupted the British invasion into New York such that it could not be mounted before the onset of winter. It was nearly a year before the advance could be renewed. In that interval American troops were recruited and trained, and on 17 October 1777, under General Horatio Gates, defeated the British decisively at Saratoga, New York. This victory was a primary factor in bringing about the alliance with France, and bringing the powerful French navy to the aid of the Colonies.
See main article: Siege of Fort Ticonderoga (1777). During the British advance prior to the Battle of Saratoga, Enterprise was one of five vessels assigned to duty convoying bateaux in the evacuation of Ticonderoga. The small American force was no match for the British fleet on Lake Champlain, and after two ships had been captured, Enterprise and the other two were run aground on 7 July 1777, and burned to prevent their capture.
