Burgoyne then suffered defeat in Bennington, Vermont, and bloody draws at Bemis Heights, New York. On October 17, 1777, a frustrated Burgoyne retreated 10 miles and surrendered his remaining 6,000 British forces to the Patriots at Saratoga. Upon hearing of the Patriot victory, France agreed to recognize the independence of the United States. It was, of course, France's eventual support that enabled the Patriots' ultimate victory.
