At the battle of Mine Run, Adjutant Joseph Craig's horse was shot from under him just as the regiment was going into action. Taking off the accoutrements, he sent them to the rear, and supposed he had seen the last of the old horse which had carried him over so many miles of the “sacred soil;” but what was his surprise, next morning, to see the “big bay” walking around in the rear of the regiment. He had been shot by a musket-ball between the eyes, the bullet just penetrating the frontal bone, but not entering. He was useless, however, for his intellect, or instinct, seemed to have left him, and he could not be guided by the rein, but would go wherever he chose, in spite of curb, bit, or spur. A bullet from one of the men's Springfield rifles ended his war record.
