To avoid the hardships and dangers of a siege in a town too extensive to be defended by his sickly garrison, and inhabited by persons known to be hostile, Murray took the bold resolution of hazarding a battle. Having formed this determination, he led out his garrison to the heights of Abraham, and attacked the French near Sillery. He was received with unexpected firmness; and, perceiving that his utmost efforts could make no impression, he called off his army, and retired into the city. In this fierce encounter, the English loss amounted to near one thousand men; and they represent that of the French to have been not less considerable. [Sidenote: Quebec besieged.] Monsieur de Levi improved his victory to the utmost. His trenches were opened before the town, on the same evening; but such was the difficulty of bringing up his heavy artillery, that near a fortnight elapsed before he could mount his batteries, and bring his guns to bear on the city. The batteries had been opened but a few days, when the garrison was relieved from its perilous situation, by the arrival of a British fleet. Quebec being secure, Monsieur de Levi raised the siege, and retired to Montreal. During these transactions, general Amherst was taking measures for the annihilation of the remnant of French power in Canada. He determined to employ the immense force under his command for the accomplishment of this object, and made arrangements, during the winter, to bring the armies from Quebec, lake Champlain, and lake Ontario, to act against Montreal. The preparations being completed, the commander in chief marched at the head of upwards of ten thousand British and provincials, from the frontiers of New York to Oswego, where he was joined by sir William Johnson, with one thousand Indians. He embarked his army at that place, and proceeded down the St. Lawrence to Montreal. Murray, who had been directed to advance up the river to the same point, with as many men as could be spared from Quebec, appeared below the town on the very day that Amherst approached it from above. The two generals found no difficulty in disembarking their troops, and the whole plan of co-operation had been so well concerted that, in a short time, they were joined by colonel Haviland with the detachment from Crown Point. [Sidenote: Montreal capitulates.] The junction of these armies presenting before Montreal a force not to be resisted, the governor offered to capitulate. In the month of September, Montreal, and all other places within the government of Canada, then remaining in the possession of France, were surrendered to his Britannic majesty. The troops were to be transported to France, and the Canadians to be protected in their property, and the full enjoyment of their religion.[176] [Footnote 176: Minot. Belknap. Belsham. Russel.]
