James Wilkinson
Sent to Canada as part of the reinforcements for Benedict Arnold's army attacking Quebec, he arrived just in time to see the arrival of 8,000 British reinforcements under General John Burgoyne – which caused the collapse of the American effort in Canada. He became assitant to Arnold just before to the final retreat and left Canada with Arnold on the very last boat out. Shortly after that, he left Arnold's service and became an assitant to General Horatio Gates in August 1776.
