Berryville, I was ordered in line of battle, and advanced through the town, the enemy having retired before us. From this point we moved on Martinsburg, getting into position about 6 o'clock P. M. on the 14th. After being under shelling for a few moments, I was ordered forward, and with the rest of the brigade occupied the town shortly after dark; the march was resumed on the 15th, moving to the Potomac river, arrived at Williamsport, and reached Greencastle, Pennsylvania, on the 22d of June. Very respectfully, &c.,
C. Forsyth, Lieutenant-Colonel Commanding.
