Answer:
Americans controlled high ground at Bemis Heights to eventually surround British and force surrender.
Step-by-step explanation:
General Horatio Gates was the American commander who confronted the British lead by General John Burgoyne; their troops were traveling south from Canada with the intention of taking control of the New York region. In the meantime, Americans were building fortifications on Bemis Heights, a high ground that oversees the Hudson River valley, where British were headed. A good view and fortressed walls at the base of the ridge gave the Americans the possibility to control the area; After some weeks of fighting, Burgoyne's troops were surrounded and forced to surrender on October 17, 1777.
