Gillespie delivered the order about 1 o’clock, and when the corps was put in motion, General Warren joined me at the front. Before he came, I had received, through Colonel Babcock, authority from General Grant to relieve him, but I did not wish to do it, particularly on the eve of battle; so, saying nothing at all about the message brought me, I entered at once on the plan for defeating Pickett, telling Warren how the enemy was posted, explaining with considerable detail, and concluding by stating that I wished his troops to be formed on the Gravelly Church road, near its junction with the White Oak road, with two divisions to the front, aligned obliquely to the White Oak road, and one in reserve, opposite the centre of these two.
General Warren seemed to understand me clearly, and then left to join his command, while I turned my attention to the cavalry, instructing Merritt to begin by making demonstrations as though to turn the enemy’s right, and to assault the front of the works with his dismounted cavalry as soon as Warren became engaged. Afterward I rode around to Gravelly Run Church, and found the head of Warren’s column just appearing, while he was sitting under a tree making a rough sketch of the ground. I was disappointed that more of the corps was not already up, and as the precious minutes went by without any apparent effort to hurry the troops on to the field, this disappointment grew into disgust. At last I expressed to Warren my fears that the cavalry might expend all their ammunition before the attack could be made, that the sun would go down before the battle could be begun, or that troops from Lee’s right, which, be it remembered, was less than three miles away from my right, might, by striking my rear, or even by threatening it, prevent the attack on Pickett.
Warren did not seem to me to be at all solicitous; his manner exhibited decided apathy, and he remarked with indifference that “Bobby Lee was always getting people into trouble.” With unconcern such as this, it is no wonder that fully three hours’ time was consumed in marching his corps from J.[G] Boisseau’s to Gravelly Run Church, though the distance was but two miles. However, when my patience was almost worn out, Warren reported his troops ready, Ayres’s division being formed on the west side of the Gravelly Church road, Crawford’s on the east side, and Griffin in reserve behind the right of Crawford, a little different from my instructions. The corps had no artillery present, its batteries, on account of the mud, being still north of Gravelly Run. Meanwhile Merritt had been busy working his men close up to the intrenchments from the angle of the return west, along the White Oak road.
