Besides the complaints which reached Washington from all sides, he had also to listen to the advice of military amateurs. Some of these had never been in a battle and knew nothing about warfare except from reading, but they were not on this account the most taciturn. Many urged strongly that an expedition be sent against Canada, a design which Washington opposed. His wisdom was justified when Richard Montgomery, with about fifteen hundred men, took Montreal--November 12, 1775--and after waiting several weeks formed a junction with Benedict Arnold near Quebec, which they attacked in a blinding snowstorm, December 31, 1775. Arnold had marched up the Kennebec River and through the Maine wilderness with fifteen hundred men, which were reduced to five hundred before they came into action with Montgomery's much dwindled force. The commander of Quebec repulsed them and sent them flying southward as fast as the rigors of the winter and the difficulties of the wilderness permitted. By the end of July, meanwhile, Washington had brought something like order into the undisciplined and untrained masses who formed his army, but now another lack threatened him: a lack of gunpowder. The cartridge boxes of his soldiers contained on an average only nine charges of ball and gunpowder apiece, hardly enough to engage in battle for more than ten minutes. Washington sent an urgent appeal to every town, and hearing that a ship at Bermuda had a cargo of gunpowder, American ships were despatched thither to secure it. In such straits did the army of the United Colonies go forth to war. By avoiding battles and other causes for using munitions, they not only kept their original supply, but added to it as fast as their appeals were listened to. Washington kept his lines around Boston firm. In the autumn General Gage was replaced, as British Commander-in-Chief, by Sir William Howe, whose brother Richard, Lord Howe, became Admiral of the Fleet. But the Howes knew no way to break the strangle hold of the Americans. How Washington contrived to create the impression that he was master of the situation is one of the mysteries of his campaigning, because, although he had succeeded in making soldiers of the raw recruits and in enforcing subordination, they were still a very skittish body. They enlisted for short terms of service, and even before their term was completed, they began to hanker to go home. This caused not only inconvenience, but real difficulty. Still, Washington steadily pushed on, and in March, 1776, by a brilliant manoeuvre at Dorchester Heights, he secured a position from which his cannons could bombard every British ship in Boston Harbor. On the 17th of March all those ships, together with the garrison of eight thousand, and with two thousand fugitive Loyalists, sailed off to Halifax. Boston has been free from foreign enemies from that day to this. CHAPTER V TRENTON AND VALLEY FORGE
