Nickerson moved forward on the right in column of regiments. The 14th Maine, deployed as skirmishers, covered his front, followed by the 24th Maine, 177th New York, and 165th New York in line. After emerging from the woods, Nickerson's right flank rested on the road that runs past Slaughter's house, near the position of battery 16.
Dow formed the left of the division and of the army. He advanced at the same time as Nickerson, and in like order, his right resting near the position of battery 17 and his left near Gibbons's house, marked as the position of battery 18. The 6th Michigan led the brigade, followed by the 15th New Hampshire, 26th Connecticut, and 128th New York.
In the interval between the two brigades rode Sherman, surrounded by his whole staff and followed by his escort.
No sooner had the line emerged from among the trees than the Confederates opened upon every part of it, as it came in sight, a galling fire of musketry and artillery. At first the troops moved forward steadily and at a good pace, but as they drew nearer to the enemy and the musketry fire grew hotter, their progress was delayed and their formation somewhat broken by four successive and parallel lines of fence that had to be thrown down and crossed. Once clear of the young corn, they found themselves entangled with the abatis that covered and protected the immediate front of the Confederate works on this part of the line. This had been set on fire by the exploding shells, and the smoke and flame now added to the difficulty of the movement. Here the men suffered greatly, many being shot down in the act of climbing the great trunks of the fallen trees, and many more having their clothing reduced to tatters and almost torn from their bodies in the attempt to force their way through the entangled branches. The impetus was soon lost, the men lay down or sought cover; numbers of Dow's men made their way to the grove in their rear and into the gully on their left; of Nickerson's, many drifted singly and in groups into the ravine on their right.
Long before this, indeed within a few minutes after the line first marched out from the wood, Sherman had fallen from his horse, severely wounded in the leg; under the vigorous fire concentrated upon this large group of horsemen in plain sight of the Confederates and in easy range, two of his staff officers had shared the same fate. This would have brought Dow to the command of the division; but nearly at the same instant Dow himself was wounded and went to the rear, and so the command fell to Nickerson, who was with his brigade, and, in the confusion of the moment, was not notified. Thus, for some interval, there was no one to give orders for fresh dispositions among the regiments. Many officers had fallen; the 128th New York had lost its colonel, Cowles; the 165th New York, at last holding the front of Nickerson's line, had lost two successive commanders, Abel Smith and Carr, both wounded, the former mortally, while standing by the colors. To retire was now only less difficult than to advance. Nickerson's men, lying down, held their ground until after dark; but Dow's, being nearer the cover of the woods, fell back to their first position.
