Fairfax Court-House, March 23, 1863.

Sir:—At 5 P.M., our picket in front of Chantilly was attacked. The videttes were on the alert, and gave the alarm. The reserve of about 70 men were immediately under arms, and charged the enemy, who fled for 2 miles along the Little River turnpike. Between Saunder's toll-gate and Cub Run there is a strip of woods about a half a mile wide through which the road runs. Within the woods, and about a quarter of a mile apart, are two barricades of fallen trees; our troops pursued the enemy between these barricades. Behind the latter, some of the enemy were concealed. The head of the column was here stopped by a fire of carbines and pistols, and also by a fire upon the flank from the woods. The column broke, and was pursued by the enemy 1½ miles. It was then rallied by the exertions of Majors Bacon and White. Captains McGuinn and Hasbrouck, when they heard of the alarm, proceeded on a gallop from Fryingpan, and, joining Major White's command, pursued the enemy for 8 miles. Night coming on, and the enemy being more numerous than we were, and our horses exhausted, the column halted and returned to Chantilly. The line of pickets is now established. Our loss is, killed, Corporal Gilles, Company H. Fifth New York Cavalry; James Doyle, Company C; John Harris, Company L. Mortally wounded, Sergeant Leahey, Company C. Lieutenant Merritt taken prisoner.

Lieutenant Colonel Commanding.
