was placed in position under difficult circumstances, and beautifully handled by Captain Graham under a severe fire, in which he lost heavily in men and horses. Colonel Hays, under whose observation the service was rendered, has recommended Captain Graham and Lieutenant Elder, his first lieutenant, for a brevet, in which I concur.

The horse artillery accompanied the cavalry, and occupied the gap in the center of the line of battle, between Hancock's division and Burnside's corps, and became warmly engaged with the enemy.

On the 19th instant the horse artillery accompanied the cavalry in pursuit of the enemy. They were closely followed by the Reserve Artillery under Colonel Hays, a number of whose batteries took part in the artillery combat between the batteries on opposite sides of the Potomac. The enemy's gunners and their supports being driven off, a small body of our infantry crossed the river and secured six of the abandoned guns. As these operations took place under the immediate orders of General Porter, I respectfully refer you to his report for the particulars.

The artillery attached to the divisions performed their duties creditably and gallantly, and there were many instances of desperate fighting. The enemy repeatedly attempted to carry our batteries, but were in every instance driven back, a circumstances due in a great degree to the care taken in posting their supports.

I have to acknowledge the services in this campaign of Lieutenant E. R. Warner, Third Artillery, my assistant adjutant-general, and the only officer on my staff. He was zealous and indefatigable in his labors to ascertain and provide for the deficiencies of the batteries, and performed his duties gallantly on the field.

Lieutenant-Colonel Hays, commanding the Reserve Artillery and batteries of position, performed his duties with his usual skill, judgment, and effect. His reputation is too well established to require further commendation from me.

Lieutenant W. D. Fuller, Third Artillery, in charge of the reserve ammunition column, is entitled to special credit for his energy in organizing the train and bringing it forward from Washington. Upon his labors depended the supply of ammunition not only to the reserve, but to most of the division batteries on the field, and he did his work thoroughly and efficiently.

The conclusion of the battle left the artillery of the army scant of men, of horses, of ammunition, of supplies of every description. The greater portion of the batteries had, before entering on this campaign, neither the time nor the opportunity to repair the losses and damages or replace the expenditures of the previous one. An almost complete reorganization and reassignment was necessary. All efforts were immediately directed to placing them in condition again to take the field. Notwithstanding these efforts, they were not fully prepared when the army crossed the Potomac, and large portions of the supplies the required were not received until after they reached this place. To the constant employment of the battery officers, chiefs of artillery, and myself in the performance of these, the most important and necessary duties at the time, must be attributed my inability to prepare a more complete or satisfactory report of the artillery operations of the campaign.

Respectfully, your obedient servant,

HENRY J. HUNT,

Brigadier General Vols., Chief of Artillery, Army of the Potomac.

Brigadier General R. B. Marcy,

(Late) Chief of Staff, Army of the Potomac.
