(September 17, 1862.)
Between 9 and 10 A.M. of the 17th, the four Batteries of this Battalion, under command of Captain Carey F. Grimes, went into position on this ridge in support of the Infantry engaged on the high ground northeast. Grimes' (Virginia) Battery was on the immediate right of the pike, Moorman's (Virginia) Battery, on Grimes' right and between it and Piper's Stone Barn, Huger's (Virginia) Battery was immediately west of the pike, and Donaldsonville (Louisiana) Artillery (Maurin's Battery) on Huger's left, on the rising ground 140 to 170 yards northwest of this. The Battalion was subjected to heavy fire of Federal Artillery and musketry; Captain Grimes was mortally wounded about 60 yards east of this by a musket ball, many men and horses were killed and wounded, some of the guns were disabled and the Battalion was withdrawn toward Sharpsburg by Major John S. Saunders who was not present when it went into action.
Later in the day parts of the command assisted in checking the advance of the Ninth Corps on Sharpsburg.
