Ford, division ordnance officer, whose efficiency in bringing up the ammunition train and supplying the division, and taking from the battle- field part of the arms and destroying the rest, deserves especial commendation.

The Third Brigade (Egan's) was the most hotly engage, and acquitted itself most gallantly. Colonel Egan, for the first time in command of the brigade, exhibited much skill in handling the troops. The division is now in camp in good condition and spirits, and I have the pleasure to report that the straggling, considering that the marches were for two nights, was confined to a few.

I regret to say that the command has experienced a serious loss in the death of Lieutenant- Colonel Trepp, commanding First U. S. Sharpshooters, killed in the skirmish and advance at Mine Run.

MAJOR: I have the honor to report the following number of arms brought off the battle- field after the late action on Friday, the 27th ultimo: Rifled muskets, 165. These guns were of Richmond, Enfield, Springfield, and other manufacture.

In addition to the above, there were collected by the detail under my charge three or four hundred guns, which, as I was unable to bring them off for want of transportation, I caused to be destroyed.
