Major General Guy Carleton, governor of Quebec, knew an invasion was imminent, given the history of colonial attempts to capture French Quebec. With limited resources and uncertain loyalty from the local population, Carleton relied on defensive strategies and hoped the Quebec Act of 1774 would secure French-Canadian support. And as the Continental Army laid siege to Fort St. John, led by the experienced yet reluctant rebel General Richard Montgomery. Benedict Arnold embarked on a perilous overland march through the Maine wilderness. Facing sabotage, harsh conditions, and starvation Arnold and his men reached Quebec, but they were too late. The city was now fortified and ready for a fierce defense.
