CEIVED ORDERS FROM HIM TO TAKE A POSITION ON THE HILL AND WEST OF THE TOWN, AND ENGAGE THE ENEMY'S BATTERIES. I PROCEEDED AT ONCE AND TOOK POSITION AS DIRECTED, AND OPENED FIRE AT 12. 30 P. M. I SUCCEEDED IN SILENCING ONE OF THE ENEMY'S BATTERIES AT 2 P. M. ANOTHER BATTERY WAS THEN BROUGHT INTO THE OPEN FIELD AT A RANGE OF 700YARDS. THIS BATTERY WAS DISABLED BEFORE THEY COULD DO ME ANY DAMAGE. THE ENEMY THEN FORMED A DIVISION OF INFANTRY, AND CHARGED DESPERATELY UPON MY BATTERY, BUT WERE PROMPTLY REPULSED AND DRIVEN BACK FROM THE FIELD WITH GREAT SLAUGHTER BY OUR INFANTRY AND ARTILLERY. THE ENEMY MADE A SECOND ATTEMPT TO FORM, BUT WERE BROKEN AND FORCED TO RETIRE. I CEASED FIRING AT 5. 30 P. M., BY ORDER OF GENERAL DOUBLEDAY, AFTER FIVE HOURS' ENGAGEMENT. I REMAINED ON THE FIELD UNTIL 7 A. M. THE 4TH INSTANT, AT WHICH TIME I WAS RELIEVED BY CAPTAIN CLARK, COMMANDING A NEW JERSEY BATTERY, AND PERMITTED TO RETIRE FROM THE FIELD. I EXPENDED 322 ROUNDS. THE AMMUNITION USED WAS HOTCHKISS SHOT AND SHELL AND CANISTER. MY LOSS DURING THE ENGAGEMENT WAS PRIVATE JOHN W. BARBER KILLED; CORPL. C. HASS, PRIVATES T. P. SMITH, HARVEY COLLINS, AND J. M. C. FORBES, ALL SLIGHTLY WOUNDED. I ALSO LOST 23 HORSES KILLED, AND RECEIVED SLIGHT DAMAGE TO TWO AMMUNITION CHESTS. THE OFFICERS AND MEN BEHAVED WELL, EVINCING GREAT COOLNESS AND BRAVERY.

I AM, SIR, YOUR MOST OBEDIENT SERVANT,
