 This defeat was instrumental to the momentum of the Revolutionary War, as the defeat of the British army along the Champlain-Hudson waterway convinced France to ally with the American army.Following the failed British campaign led by General Burgoyne, the British still maintained control over the Champlain waterway for the duration of the Revolutionary War.The British used the Champlain waterway to supply raids across the Champlain Valley from 1778 to 1780, and Lake Champlain permitted direct transportation of supplies from the British posts at the northern end of the lake.
