Finally on October 17, 1777, Burgoyne formally surrendered. Under the generous terms of the Convention of Saratoga, Burgoyne was allowed to march out of camp "with the Honors of War", which included retaining his colors and the return of his men to England. His 6,000 men marched out of their camp, surrendered their weapons and began their march west. However, when they reached New England, Gates' terms were not honored and the British soldiers spent months in sparse guarded camps.
Oh, and something else happened in 1781...
