At the common signal for the attack, the division commanded by this officer moved in files along the street of St. Roques towards the Saut de Matelots, where the first barrier had been constructed, and a battery of two twelve pounders erected. 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. The path along which the troops were to march was so narrow, that the two pieces of artillery in the battery were capable of raking with grape shot every inch of the ground; whilst the 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 along the St. Charles with the utmost intrepidity. The alarm was immediately given, and the fire on his flank commenced. As he approached the barrier, he received a musket ball in the leg which shattered the bone, and was carried off the field. 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. The barricade was instantly mounted, on which the battery was deserted without a discharge from another gun. The captain of the guard, with the greater number of his men, were made prisoners. Morgan formed his troops 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 dark--and he had not the slightest knowledge of the course to be pursued, or of the defences to be encountered. Under these circumstances, it was thought unadviseable to advance farther. They were soon joined by Lieutenant Colonel Green, and Majors Bigelow and Meigs, with several fragments of companies, so as to constitute altogether about two hundred men.
