It being found impracticable to turn the enemy's left, which was found protected by a deep and impassable canal, running along the entire front, General Sedgwick decided to assault the center at Marye's Heights, where the works were gallantly carried by Newton's division, of the Sixth Corps, my batteries assisting with their fire. As soon as the heights were carried, I, according to instructions previously received from General Sedgwick, moved by the left flank into town again, under a heavy artillery fire, and joined in the pursuit of the enemy.

The division captured a number of prisoners, and afterward returned to the town, securing seven pieces of artillery, abandoned by the enemy, and took up position to defend the crossing of the river.

From the morning of the 4th, when the enemy again occupied his earthworks, until we abandoned the town and took up the bridges, Hall's brigade was almost constantly engaged in skirmishing with the enemy, and finally retreated to this side in most excellent order.

The loss in the division was as follows:

Command. Killed. Wounded. Missing. Total.

First Brigade, Colonel Laflin --- 16 4 ---

Third Brigade, Colonel Hall 3 56 8 ---

Brown's battery (B), 1st Rhode --- --- --- ---

Island Artillery

Adams' battery (G), 1st Rhode 5 18 --- ---

Total 8 90 12 110
