and how many were carried off it is difficult to say. After the affair we built our bivouac fires in Dranesville.
Thus, sir, we, on returning to camp, had marched 24 miles, beaten the enemy, loaded our wagons with forage, bringing in [12 miles] our killed  and wounded , among whom are 4 captains. Some of our wounded had to be brought the whole distance on stretchers, while I am informed the Pennsylvania ambulances for this division are lying empty at Washington. Lists of killed and wounded and reports of regimental commanders are herewith inclosed.
It is impossible to remember all who were conspicuous, especially as the fighting occurred in thickets and was scattered over much ground. Captain Easton was very efficient and his battery well served.
The wounded officers, Lieutenant-Colonel Kane and Captain Niles, of the Kane Rifles; Captain Bradbury, of the Sixth, and Captains Dick and Galway, of the Ninth, Pennsylvania Reserve Volunteer Corps, were conspicuous, leading their men when wounded. Others there were, as you can well imagine, equally brave, but it would be invidious to attempt to select them.
The prisoners report that the brigade engaged against us was composed of the Kentucky Rifles, an Alabama, a South Carolina, and a Virginia regiment, with a 6-gun battery, all under the command of General Stuart.
I must not forget the prompt manner in which General Reynolds came up from Difficult Creek, some 4 miles off, as soon as he heard the cannonading. He arrived too late, it is true, to take part in the affair, but the certainty that he would come with his brigade insured a victory, and stimulated our men to earn it.
With respect, sir, your obedient servant,
E. O. C. ORD,
Captain H. J. BIDDLE,
Assistant Adjutant-General, McCall's Division.
HEADQUARTERS McCALL'S DIVISION, Camp Peirpoint, Va., December 19, 1861.
GENERAL: You will please move in command of your brigade at 6 a.m. to-morrow, on the Leesburg pike, in the direction of Dranesville. The First Rifles, Pennsylvania Reserves, Lieutenant-Colonel Kane, have been ordered to form right in front on the pike near Commodore Jones' house and await your arrival, when the commanding officer will report to you for further orders.
Captain Easton's battery has been directed to form on the left of the Rifles. The captain will report to you for orders.
Two squadrons of cavalry will also be placed under your command. The senior officer will report to you this evening for orders. Sherman, the guide, will likewise report to you for duty.
The object of this expedition is twofold: In the first place, to drive back the enemy's pickets, which have recently advanced within 4 or 5 miles of our lines [leaving a force of about 70 cavalry at Henderson's], and carried off two good Union men, and threatened others; and, secondly, to procure a supply of forage.
It has to-day been reported to me that there is a force of about 100 cavalry lying between Dranesville and the river. This force might be captured or routed by sending a regiment of infantry up the pike be-
