Answer:
Burgoyne's plan was to take control of the Hudson River and in doing so he believed they would be able to isolate New England.
Explanation:
The Saratoga campaign was led by John Burgoyne, who was a poet, a playwright and also served as a General in British Army. In 1777, General Burgoyne led a troop of some 8,000 men from Canada moving towards south.
General Burgoyne's plan to lead this British troop was to take control of the Hudson River eventually leaving the New England isolated from other twelve American colonies. He belived that he would be able to execute this plan successfully and will be able to set British General William Howe free.
The plan of overpowering the Hudson River failed which became the last element that led to American independence.
