Saratoga campaign

The Saratoga Campaign in 1777 was an attempt by the British high command for North America to gain military control of the strategically important Hudson River valley during the American Revolutionary War. It ended in the surrender of the British army, which historian Edmund Morgan argues, "was a great turning point of the war, because it won for Americans the foreign assistance which was the last element needed for victory.

The primary thrust of the campaign was planned and initiated by General John Burgoyne. Commanding a main force of some 8,000 men, he moved south in June from Quebec, boated up Lake Champlain to middle New York, then marched over the divide and down the Hudson Valley to Saratoga. He initially skirmished there with the Patriot defenders with mixed results. Then, after losses in the Battles of Saratoga in September and October, his deteriorating position and ever increasing size of the American army forced him to surrender his forces to the American General Horatio Gates on October 17.
