The USS Liberty was a schooner built at Skenesboro, New York, on Lake Champlain, for wealthy landowner and former British Army Captain Philip Skene.

North of Isle La Motte, the schooner was becalmed, but General Benedict Arnold with a party of 35 men pressed on in small boats.

[1] Liberty and the prize, renamed Enterprise, gave the Americans undisputed control of the entire lake.

The two ships, reinforced by new vessels built at Skenesboro, supported the Continental forces during the Canadian campaign, and prepared to defend the lake when the British assumed the offensive.

During the Battle of Valcour Island, Liberty, away on a supply run, escaped the fate of most of Arnold's fleet, only to be destroyed the following summer as Burgoyne marched south.
