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.
