The troops in front wore now sharply engaging the rebels in their works, while our artillery, and their field-pieces, behind the breastworks near the fort, were blazing away at each other with great rapidity. In one instance, the rebels galloped the horses up to the parapet with a gun, and when the horses wheeled with it, in order that it might be placed in position, the infantry fire killed all the horses in the traces, and the artillerists scampered off in an instant, and left their gun. At a shot from one of our Parrott guns, which knocked one of the timbers from the breastwork, at least a hundred rebels ran away from behind the intrenchment into the bastioned fort. Our caissons were now coming from the front for ammunition. At ten minutes past three, most of Morgan’s men were in line, and the remainder were forming in the rear. In five minutes more they were advancing with vigor. Sharp musketry and artillery firing was kept up all the time. At twenty minutes past three a heavy column of Morgan’s men was seen moving to the left, near the river bank, advancing amid clouds of smoke. It was a body that was moving quickly to the front, to extend the advancing line. The time was now fifteen minutes past three. The fight was quite severe on both sides. Although the heavy guns in the fort were silenced the field-pieces and the infantry behind the parapet with great determination continued to resist our vigorous advance. The Union line extended from the river on the left, round in front of the fort, and to the bayou on the right. The engagement was general along its whole extent. Morgan sent word that his left was advancing steadily, and, as the gunboats commanded the river, he had sent for Lindsay’s brigade to return from the other side. It was now nearly four o’clock. The Admiral’s flagship was coming close to the bank, and, with the other gunboats, was pouring shot into the fort; Lindsay’s brigade, across the river, was also firing into the works, while Morgan’s and Sherman’s men were advancing fast in front. The white flag was seen in several places on the parapet; enthusiastic cheers arose from the troops in front; the firing ceased; the rebels rose from behind the breastwork; and the Federal troops rushed wildly forward with flags flying, into and over the intrenchments. The fort had surrendered.
