The Battles of Saratoga marked the climax of the Saratoga campaign, giving a decisive victory to the Americans over the British in the American Revolutionary War. British General John Burgoyne led an invasion army of 7,200–8,000 men southward from Canada in the Champlain Valley, hoping to meet a similar British force marching northward from New York City and another British force marching eastward from Lake Ontario; the goal was to take Albany, New York. The southern and western forces never arrived, and Burgoyne was surrounded by American forces in upstate New York 15 miles short of his goal. He fought two battles which took place 18 days apart on the same ground 9 miles south of Saratoga, New York.

The battle on September 19 began when Burgoyne moved some of his troops in an attempt to flank the entrenched American position on Bemis Heights. American Major General Benedict Arnold anticipated the maneuver and placed significant forces in his way. Burgoyne did gain control of Freeman's Farm, but it came at the cost of significant casualties.

Burgoyne attacked Bemis Heights again on October 7 after it became apparent that he would not receive relieving aid in time. This battle culminated in heavy fighting marked by Arnold's spirited rallying of the American troops. Burgoyne's forces were thrown back to the positions that they held before the September 19 battle, and the Americans captured a portion of the entrenched British defenses. Burgoyne was therefore compelled to retreat, and his army was surrounded by the much larger American force at Saratoga, forcing him to surrender on October 17. News of Burgoyne's surrender was instrumental in formally bringing France into the war as an American ally.
