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

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

Burgoyne led a British army south from Quebec in an attempt to control the Hudson River valley and separate New England from the other colonies. His advance depended on coordination with other British forces, but the planned support did not arrive as expected.

American forces under General Horatio Gates and other commanders defeated Burgoyne’s army in the Battles of Saratoga. After heavy fighting, dwindling supplies, and growing American strength, Burgoyne surrendered his army at Saratoga, New York, on October 17.

The victory had major international consequences. It persuaded France that the American cause had a realistic chance of success, contributing to the Franco-American alliance and French military assistance. Saratoga is therefore often described as a turning point of the American Revolutionary War, although fighting continued for several more years.
