of his, disabled. In this engagement, as in the one at Winchester, the officers and men behaved with the greatest gallantry, fully sustaining the high character which they had previously borne. After crossing into Virginia there was no serious fighting. Colonel Carter fired a few shots at the enemy advancing upon our rear in crossing the Potomac, and also fired upon them as they attempted to cross at Manassas gap. Owing to the loss by capture of the transportation and forges (with few exceptions) of First Virginia artillery and Carter's and Nelson's battalions, and the loss of ninety-two horses at Gettysburg, the artillery of the corps has had great difficulties to contend with. They brought off everything from across the river to this point, with the exception of one caisson, for the loss of which the officer responsible is now under charges. The horses are in low order, but are improving. Very respectfully,
J. Thompson Brown, Colonel and Acting Chief Artillery Second Corps.
