Under the direct orders of General George Washington, Bissell posed as a deserter in the city of New York from August 14, 1781, to September 29, 1782. He realized that to get the information Washington needed, he would have to join the British Army: for 13 months, he served in the British Infantry Corps led by Benedict Arnold. Bissell memorized everything he was able to find out and then made his way back to friendly lines where he was placed under arrest until Washington verified his story. Sergeant Bissell was able to furnish valuable information including detailed maps he drew of the enemy's positions. He was to become the last recipient of the Badge of Military Merit in June 1783, one of only three awarded by Washington himself. The award was lost in a house fire in 1813.
