th out of the forces besieging Boston. Washington was to face formidable problems in his task. First amongst them was the persistent belief in the ability of the militia to win the war without a permanent professional army. This belief in the militia system had been one of the problems faced by the British in their attempts to raise taxes in America. His second problem was that troops from the different colonies were often unwilling to serve away from their colony, or in mixed units with men from other colonies. A third problem was that the army was not properly supplied, a problem that remained for most of the war. Fourth, many of his men were serving for short periods of time and several operations, such as the 1775 invasion of Canada, were adversely effected by enlistments ending. Finally, the rebellious attitude that had prompted many to join the army also made them resistant to taking orders from officers they had not selected. Washington was to have frequent problems getting men to accept the principle that the best man should have a post, not simply the one who had served for longest.

All across the colonies, sizable militias were formed, leaving the small British garrisons vulnerable. A lack of appreciation of the scale of unrest meant that little or no aid could be expected until the following year, if at all. This allowed the American cause to gain vital momentum.of Canadaonly American setback of 1775 came in their invasion of Canada. Their invasion was based on the expectation that the recently conquered French of Quebec would rush to the aid of the invasion. If that had happened, then the weak British garrison of Canada, already used to reinforce Boston, could have been overwhelmed. As it was, the French population was relatively happy under British rule, and the Americans found themselves operating without popular support.campaign began slowly, with one advance along Lake Champlain starting in May and continuing until the surrender of St. Johns on 2 November. Another force further north was defeated outside Montreal on 25 September. Finally, a third force of 1050, under Benedict Arnold, was sent through Maine to the St. Lawrence. This force, reduced to 600 on the march, arrived outside Quebec on 9 November. Facing them was a hastily formed force commanded by Major-General Guy Carleton, the British commander in Canada.
