The Battle of Valcour Island (also called Valcour Bay) was a naval engagement fought on Lake Champlain on October 11, 1776, between a British fleet under General Guy Carleton and an American flotilla commanded by Benedict Arnold. Though most American ships were captured or destroyed, the defense of the lake stalled British plans to reach the upper Hudson River valley.

Background and detail

Background. The Continental Army retreated from Quebec to Fort Ticonderoga and Fort Crown Point in June 1776 after British forces were heavily reinforced; 10,000 British and German troops arrived in spring 1776, and Governor Guy Carleton drove the Americans out of Quebec. The Americans spent the summer fortifying those forts and building ships, while taking or destroying vessels that might aid the British.

Opposing Fleets. The 33-ship British fleet carried more than 80 guns against the Americans' 15 vessels with 74 smaller guns. The 22-gun Inflexible and 18-gun Thunderer alone outgunned the entire American fleet, which also faced HMS Maria, HMS Carleton, HMS Loyal Convert, and 28 single-masted gunboats.

Aftermath and Significance. With snow falling by October 20 and winter supply lines difficult, Carleton withdrew north to winter quarters, vindicating Arnold's strategy of delay. The battle is generally regarded as one of the first naval battles of the American Revolutionary War and among the first fought by the Continental Navy; Valcour Bay and the raised wreck of USS Philadelphia are now National Historic Landmarks.
