The division commanded by this officer moved in files, at the common signal for the attack, along the street of St. Roques, towards the Sault des Matelots. In imitation of Montgomery, he too led the forlorn hope in person, and was followed by Captain Lamb with his company of artillery, and a field piece mounted on a sled. Close in the rear of the artillery was the main body, in front of which was Morgan's company of riflemen commanded by himself. At the Sault des Matelots, the enemy had constructed their first barrier, and had erected a battery of two twelve pounders, which it was necessary to force. The path along which the troops were to march had been rendered so narrow by the rough cakes of ice thrown up on the side from St. Charles, and by the works erected by the enemy on the other, that the two pieces of artillery in the battery in front, were capable of raking with grape shot every inch of the ground, whilst his whole right flank was exposed to an incessant fire of musketry from the walls, and from the pickets of the garrison. In this order Arnold advanced with the utmost intrepidity, along the St. Charles, against the battery. The alarm was immediately given, and the fire on his flank commenced, which, however, did not prove very destructive. As he approached the barrier he received a musket ball in the leg which shattered the bone, and he was carried off the field to the hospital. Morgan rushed forward to the battery at the head of his company, and received from one of the pieces, almost at its mouth, a discharge of grape shot which killed only one man. A few rifles were immediately fired into the embrazures, by which a British soldier was wounded in the head, and the barricade being instantly mounted with the aid of the ladders, brought by the men on their shoulders, the battery was deserted without discharging the other gun. The captain of the guard, with the greater number of his men, fell into the hands of the Americans, and the others made their escape. Morgan formed the troops, consisting of his own company and a few bold individuals who had pressed forward from other parts of the division, in the streets within the barrier; and took into custody several English and Canadian burghers; but his situation soon became extremely critical. He was not followed by the main body of the division; he had no guide; and was himself totally ignorant of the situation of the town. It was yet extremely dark, and he had not the slightest knowledge of the course to be pursued, or of the defences to be encountered. Thus circumstanced, it was thought unadvisable to advance further.
