British General John Burgoyne surrendered at 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 rebellious colonies. His force captured Fort Ticonderoga but struggled to maintain supplies and coordination with other British armies.
The campaign turned against Burgoyne after American victories, including the Battle of Bennington and the Battles of Saratoga. His army became increasingly isolated and was surrounded by American forces commanded by General Horatio Gates. Burgoyne surrendered at Saratoga on October 17, 1777.
The victory had international consequences. It demonstrated that the American forces could defeat a major British army and helped persuade France to enter a formal alliance with the United States. Saratoga is therefore widely remembered as a decisive turning point, although the war continued for several years.
