His unreasonable anger was very much increased by a wound which he received. He was near a mound which his soldiers had been constructing near the city, to place engines upon for an attack upon the walls, when an arrow shot from one of the engines upon the walls struck him in the breast. It penetrated his armor, and wounded him deeply in the shoulder. The wound was very painful for some time, and the suffering which he endured from it only added fuel to the flame of his anger against the city.
