The Saratoga campaign was an attempt by Great Britain to gain military control of the strategically important Hudson River valley in 1777 during the American Revolutionary War.
The primary thrust of the campaign was made by an army of 8,000 men under the command of John Burgoyne from Quebec that moved up Lake Champlain and down the Hudson to Saratoga, New York, where the bulk of the army was forced to surrender after the climactic Battles of Saratoga in September and October.
The first of the 1777 campaigns was an expedition from Quebec led by General John Burgoyne. The goal was to seize the Lake Champlain and Hudson River corridor, effectively isolating New England from the rest of the American colonies. Burgoyne's invasion had two components: he would lead about 10,000 men along Lake Champlain towards Albany, New York, while a second column of about 2,000 men, led by Barry St. Leger, would move down the Mohawk River valley and link up with Burgoyne in Albany, New York.
