Bates, of our regiment, to advance the brigade. He gave the order, and then sprang upon the earthworks with the command, “Come on! Come on!” He had not gone five paces when he was met by a volley, one of the balls penetrating the left cheek and coming out behind the right ear. We passed him to the rear, thinking him a dying man, but in less than 60 days he was back in command of his brigade with a star, and is now a Medal of Honor man, and all for what he did in that last minute in the Crater. ”
