On what date did General John Burgoyne surrender his army at Saratoga?

General John Burgoyne surrendered his army at Saratoga on October 17, 1777.

Burgoyne led a British campaign intended to control the Hudson River Valley and divide New England from the other colonies. After battles near Saratoga in September and October, his army was surrounded, weakened, and cut off from expected support. He negotiated terms with American commander Horatio Gates.

The surrender was a major American victory and is widely regarded as a turning point in the Revolutionary War. It demonstrated that American forces could defeat a large British army in the field. The result also persuaded France to enter the war openly as an American ally in 1778.

Saratoga is sometimes remembered as one battle, but the campaign included multiple engagements. The two principal battles occurred on September 19 and October 7, while Burgoyne’s formal surrender took place on October 17.
