<P> The Battles of Saratoga ( September 19 and October 7 , 1777 ) 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 a large invasion army 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 southern and western forces never arrived , and Burgoyne was surrounded by American forces in upstate New York . He fought two small battles to break out which took place 18 days apart on the same ground , 9 miles ( 14 km ) south of Saratoga , New York . They both failed . </P>
