Colonel Board, Fifty-eighth Virginia, killed. The cannon and prisoners have been sent to Martinsburg. The enemy's loss in officers is heavy. Prisoners admit their force to have been 5,000. The commands of Jackson and Imboden, which were present, are not included in the mentioned strength. The force under my command consisted of Colonel Duval's brigade of infantry, Ninth and Fourteenth Virginia, and Ninety-first and Thirty-fourth Ohio, and fragments of the First, Second, and Third Virginia Cavalry, just off the cars; total 2,350. The Fourteenth Pennsylvania Cavalry, while the battle was going on, drove the enemy's calvary from Berryville, capturing some prisoners. Our loss will reach 200 killed and wounded, none missing.
