Which city did Burgoyne plan on taking over? ​

New York City

Explanation:

In 1777, British war generals devised a plan to bring a quick end to the war: They would effectively sever New England from the rest of the colonies by taking control of New York City, Albany, and the Hudson River. First, British General John Burgoyne would lead 8,000 troops from Canada.

The plan called for Burgoyne to advance south from Canada, up to Lake Champlain, capture Ft. Ticonderoga, and then march south along the Hudson to Albany. There he would join Sir William Howe, who would advance north along the Hudson River from New York City, already under British control.
