Final answer:
The Americans lost the Battle of Quebec due to their reliance on an ill-prepared army, failed expectations of French Canadian support, inadequate resources for the siege of Quebec, and effective British defensive strategies.
Step-by-step explanation:
The Americans lost the Battle of Quebec, one of the significant battles during the American Revolution, for a variety of reasons. First, the Americans began their invasion with an improperly trained and equipped army compared to the British's professional military. Furthermore, their strategy relied heavily on the French Canadians of Quebec siding with them against the British - a plan that failed to materialize.
Next, the American commanders, namely Colonel Benedict Arnold, Lieutenant Colonel Daniel Morgan, and Brigadier General Richard Montgomery, were unable to properly lay siege to Quebec due to lack of resources and time constraints. Finally, the British commanders, Captain William DeLaPlace, and General Sir Guy Carleton, successfully organized a defense against the invasion despite their isolation due to the harsh winter climate.
