The French advance guard was not strong enough to try to cross the bridge, so several hours passed while further French forces came up. During the afternoon, a violent cannonade began, as French guns arrived and were positioned to fire across the river. It has been suggested that Bonaparte was personally involved in directing some of the guns, and that his troops began to refer to him as "le petit caporal" (the little corporal) because of this, but there is no contemporary evidence to back this up.
