Of all the series of disastrous invasions of Canada, none was more dismal and pathetic than that of Montgomery and Arnold. The winter was unusually severe for a region which is noted for its intensely cold weather. The ground froze to the hardness of a rock, and, unable to make any impression in it with shovel and pick, the besiegers threw up walls of ice, which the cannon of the defenders sent flying into thousands of fragments. The men grew mutinous, and, realizing the desperate situation, Montgomery ordered an assault to be made on the last day of the year. The plan was for the first division under Montgomery to move down the river and attack the lower town near the citadel, while the second division under Arnold was to pass around the city to the north, assault by way of the St. Charles, and unite with Montgomery in his attack upon the Prescott gate. The other two divisions were to remain in the rear of the upper town and divert the garrison by feint attacks. A blinding snowstorm was raging and the men could hardly distinguish one another. Success depended upon surprise, but the defenders had learned of the intended attack, and Montgomery had hardly started when the battery delivered a fire which instantly killed him and both his aides. Their deaths threw his men into a panic, and they fled in such haste that they escaped the fate of their leaders. Meanwhile, Arnold had moved, as agreed upon, with his division along the St. Charles, the men bending their heads to the icy blast and protecting their muskets under their coats. As soon as the garrison caught sight of the dim figures they opened fire, but the Americans pressed on and carried the first barricade. Arnold, however, received a severe wound in the leg, and, suffering great pain, was carried to the rear. Daniel Morgan, one of the bravest officers of the Revolution, succeeded to the command, and, with his riflemen at his heels, was the first to climb the ladders placed against the barricade. Two musket-balls grazed the leader's face, which was scorched by the flash, and he was knocked down; but he instantly sprang to his feet and called upon his men to follow him. They did so with such dash that the enemy took refuge in the houses on both sides of the street. But for the disaster that had overtaken Montgomery, Quebec probably would have been captured, but Morgan's command was in darkness, the driving snow interfered with firing, and they knew nothing of the town. Only a few of the troops found the next barricade, and, when they climbed the ladders, were confronted by leveled muskets whose fire was very destructive. Not only that, but the British, who had taken refuge in the houses in the streets, kept up their firing. [Illustration: ST. PAUL'S CHURCH, NEW YORK, WHERE MONTGOMERY WAS BURIED.]
