The line thus organized was thin and worn by severe attrition. The men were losing strength and the ammunition getting low. Some gathered cartridges from their fallen comrades and distributed them as far as they would go, others went for fresh supplies.
McLaws’s column came up at nine o’clock. He reported at General Lee’s head-quarters, where he was ordered at rest, and afterwards reported to me, with General Lee’s orders for his own division, and asked the disposition to be made of R. H. Anderson’s. He was ordered to send the latter to report to General D. H. Hill.
Coincident with these arrivals, heavy columns of Federal infantry and artillery were seen crossing the Antietam. Morell’s division of the Fifth Corps was up and relieved Richardson’s of the Second, which had been in our front since its arrival on the 15th. Richardson’s following the march of the troops by the upper crossing advised us that the next engagement would be by the Second Corps, under General Sumner; Sedgwick’s division was in the lead as they marched. Our left centre was almost exhausted of men and ammunition. The divisions of French and Richardson followed in left echelon to Sedgwick. Hood’s brigades had retired for fresh supply of ammunition, leaving the guard to Walker’s two brigades, G. T. Anderson’s brigade on Walker’s right, part of Early’s brigade on Walker’s left, and the regiments under Colonels Grigsby and Stafford off the left front. McLaws’s division was called for, and on the march under conduct of Major Taylor of general head-quarters staff.
At sight of Sumner’s march, General Early rode from the field in search, as he reported, of reinforcements. His regiments naturally waited on the directions of the leader.
General Sumner rode with his leading division under General Sedgwick, to find the battle. Sedgwick marched in column of brigades, Gorman, Dana, and Howard. There was no officer on the Union side in charge of the field, the other corps commanders having been killed or wounded. General Sumner testified,—
“On going upon the field I found that General Hooker’s corps had been dispersed and routed. I passed him some distance in the rear, where he had been carried wounded, but I saw nothing of his corps at all, as I was advancing with my command on the field. There were some troops lying down on the left which I took to belong to Mansfield’s command. In the mean time General Mansfield had been killed, and a portion of his corps (formerly Banks’s) had also been thrown into confusion.”[65]
He passed Greene’s brigade of the Twelfth, and marched through the wood, leaving the Dunker chapel on his left.
As McLaws approached, General Hood was sent to give him careful instructions of the posture, of the grounds, and the impending crisis. He marched with his brigades,—Cobb’s, Kershaw’s, Semmes’s, and Barksdale’s. The leading brigade filed to the right, before the approaching march. Kershaw’s leading regiment filed into line as Sedgwick’s column approached the south side of the Dunker chapel wood,—the latter on a diagonal march,—while Kershaw’s regiment was in fair front against it. The regiment opened prompt fire, and the other regiments came into line in double time, opening fire by company as they came to the front. The other brigades came into line by companies, and forward into line by regiments. Armistead’s brigade had been drawn from R. H. Anderson’s column to reinforce McLaws.
