Burgoyne, seeking to command a major force, proposed to isolate New England by an invasion from Quebec into New York. This had already been attempted by General Carleton in 1776, although he had stopped short of a full-scale invasion due to the lateness of the season. Carleton was heavily criticized in London for not taking advantage of the American retreat from Quebec, and he was also intensely disliked by Germain. This, combined with rival Henry Clinton's failed attempt to capture Charleston, South Carolina, placed Burgoyne in a good position to get command of the 1777 northern campaign.
