Colonel McMaster, of the Seventeenth South Carolina, Evans' brigade, reports that he carried into the battle only 59 officers and men, so great had been his losses from sickness and wounds and straggling. Out of these he lost 19 in battle. There are no separate returns of the losses of Evans' brigade at Boonsboro gap and Sharpsburg, but in these two they are reported as follows: Holcombe legion, 18 wounded; Seventeenth, 18 killed, 49 wounded; Eighteenth, 3 killed, 39 wounded; Twenty-second, 8 killed, 64 wounded; Twenty-third, 14 killed, 66 wounded; aggregate, 43 killed, 236 wounded.

While D. H. Hill was defending the center, Longstreet's line was assailed, on Lee's right. Crossing at the bridge and fords General Burnside's troops threw their masses against D. R. Jones' division. Jenkins' brigade under Colonel Walker was on the left of Jones' division, and the operations are reported by Colonel Walker. During the 16th the brigade lay in line south of the Boonsboro road exposed to an incessant fire of artillery from batteries posted east of the Antietam. In the afternoon of the 17th Walker was moved forward, and supported a part of the Washington artillery, of New Orleans. These gallant batteries were constantly engaged, and drew an unceasing fire upon Walker as well as themselves. The guns withdrew for ammunition and Walker went forward 400 yards to an apple orchard. The enemy being near, Walker attacked with the Palmetto sharpshooters and the Second rifles on the right, the Sixth, Fifth and First continuing the line to the left.

The fire of the brigade was so steady and so well delivered,
