A makeshift flotilla of ships built and commanded by Benedict Arnold to defend Lake Champlain was attacked by Sir Guy Carletons flotilla of British ships and gunboats and all but destroyed. Although several of the American boats escaped during the night, which was particularly foggy, Carleton caught up with them again by the 13th, and what he didn't destroy, Arnold beached and fired.

Although Arnold was decisively beaten, he had successfully delayed Carleton from attacking south from Canada and taking Fort Ticonderoga which General Burgoyne was hoping to use to begin his campaign the following year.
