SEVENTEENTH Army Corps. In this position the command remained, having out a strong line of skirmishers, until the 24th of June, when the THIRD Brigade, having moved to the rear and joined the forces on the line of circumvallation, I moved my command on to the ground evacuated by it on the right of the DIVISION, and in this last position remained until the surrender of Vicksburg, on the 4th of July, when my command moved into the city. .

During the entire siege the health and morale of the command were excellent, and none seemed to have a desponding thought or a doubt as to successful result, and whether called upon to dig rifle-pits, throw up intrenchments, skirmish with the enemy, or stand to arms by day or on dark, stormy night, all was done with the greatest alacrity. Every man of my command seemed determined to do his whole duty. The following is the list of casualties occurring after the assault and during the siege. *

Respectfully submitted.
