On what date did British General John Burgoyne surrender at the Battles of Saratoga?

British General John Burgoyne surrendered at the Battles of Saratoga on October 17, 1777.

Burgoyne commanded a British army moving south from Canada through the Hudson River valley. The campaign was intended to separate New England from the other American colonies, but supply problems, difficult terrain, and growing American resistance weakened his position.

The campaign included major engagements on September 19 and October 7. After the second battle, Burgoyne's army was surrounded and short of supplies. He surrendered at Saratoga, New York, to the American forces commanded by General Horatio Gates.

The victory had consequences far beyond the battlefield. It persuaded France that the American cause had a realistic chance of success, helping produce the Franco-American alliance of 1778. Saratoga is often called a turning point of the Revolutionary War. It should not be confused with Cornwallis's surrender at Yorktown, which occurred four years later.
