Lieutenant [John S.] Sullivan, of the ambulance corps, deserves the highest credit for his courage and the fearless manner he discharged his duties, continually, under the fire of the enemy's skirmishers, bringing off the wounded and assisting in keeping up the stragglers. Lieutenant W. E. Potter, ordnance officer, was indefatigable in the discharge of his duties. Captain George P. Corts, assistant adjutant-general, and my aide, Lieutenant David Shields, Sixty-third Pennsylvania Volunteers, were constantly by my side, exhibiting, as always heretofore, self-possession and courage of the highest order. Captain Corts lost 2 horses, killed, and Lieutenant Shields l. Division quartermaster, Captain [Marshall I.] Ludington, and commissary officer, Captain [Columbus J.] Queen, discharged their duties to my entire satisfaction, and deserve the notice of their respective departments. Second Lieutenant E. J. Hueston, One hundred and eleventh New York Volunteers, attracted my attention by his exemplary conduct in charge of posting and encouraging our pickets. As a present recognition, I have appointed him an acting aide on my staff. By accompanying report, the entire loss of the division in the two days' action will be seen to be 1, 285 men killed, wounded, and missing.

I am, very respectfully, your obedient servant,

ALEX. HAYS,

Brigadier-General of Volunteers, Commanding Division.

Lieutenant Colonel C. H. MORGAN, Chief of Staff.
