The Second and Eleventh fought with distinction both on August 29th and 30th, losing 15 killed and 153 wounded. Barksdale's brigade did not participate in the fighting of Second Manassas, but after marching through Maryland to Pleasant Valley shared with Kershaw's brigade on September 13th the honor of capturing Maryland Heights. This achievement compelled the surrender of Harper's Ferry, and much of the credit for it is due to the gallant Mississippi skirmishers under Maj. J. M. Bradley.

S. F. Butler of the same regiment received a painful wound, and Maj. T. S. Evans was killed. Col. John M. Stone, Lieut.-Col. D. W. Humphreys, and Maj. J. A. Blair, of the Second Mississippi, were all wounded while leading that distinguished regiment in the charge.’ The Eleventh lost 8 killed and 96 wounded, the Second 27 killed and 127 wounded, a very large part of their total strength.

Barksdale's brigade went into the fight at Sharpsburg 891 strong, and lost in killed 33 and in wounded 257. But, although there were not enough of them to make a single continuous line in the space assigned, they drove the enemy before them. General McLaws said that the
