At six o'clock, before reaching Parker's store, Warren discovered the enemy. He sent word back to this effect, and was ordered to halt and prepare to meet and attack him. Wright, with his division of Sedgwick's corps, was ordered, by any road he could find, to join on to Warren's right, and Getty with his division, also of Sedgwick's corps, was ordered to move rapidly by Warren's rear and get on his left. This was the speediest way to reinforce Warren who was confronting the enemy on both the Orange plank and turnpike roads.

Burnside had moved promptly on the 4th, on receiving word that the Army of the Potomac had safely crossed the Rapidan. By making a night march, although some of his troops had to march forty miles to reach the river, he was crossing with the head of his column early on the morning of the 5th. Meade moved his headquarters on to Old Wilderness Tavern, four miles south of the river, as soon as it was light enough to see the road. I remained to hasten Burnside's crossing and to put him in position. Burnside at this time was not under Meade's command, and was his senior in rank. Getting information of the proximity of the enemy, I informed Meade, and without waiting to see Burnside, at once moved forward my headquarters to where Meade was.

It was my plan then, as it was on all other occasions, to take the initiative whenever the enemy could be drawn from his intrenchments if we were not intrenched ourselves. Warren had not yet reached the point where he was to halt, when he discovered the enemy near by. Neither party had any advantage of position. Warren was, therefore, ordered to attack as soon as he could prepare for it. At nine o'clock Hancock was ordered to come up to the support of Getty. He himself arrived at Getty's front about noon, but his troops were yet far in the rear. Getty was directed to hold his position at all hazards until relieved. About this hour Warren was ready, and attacked with favorable though not decisive results. Getty was somewhat isolated from Warren and was in a precarious condition for a time. Wilson, with his division of cavalry, was farther south, and was cut off from the rest of the army. At two o'clock Hancock's troops began to arrive, and immediately he was ordered to join Getty and attack the enemy. But the heavy timber and narrow roads prevented him from getting into position for attack as promptly as he generally did when receiving such orders. At four o'clock he again received his orders to attack, and General Getty received orders from Meade a few minutes later to attack whether Hancock was ready or not. He met the enemy under Heth within a few hundred yards.

Hancock immediately sent two divisions, commanded by Birney and Mott, and later two brigades, Carroll's and Owen's, to the support of Getty. This was timely and saved Getty. During the battle Getty and Carroll were wounded, but remained on the field. One of Birney's most gallant brigade commanders—Alexander Hays—was killed.

I had been at West Point with Hays for three years, and had served with him through the Mexican war, a portion of the time in the same regiment. He was a most gallant officer, ready to lead his command wherever ordered. With him it was "Come, boys," not "Go."

Wadsworth's division and Baxter's brigade of the 2d division were sent to reinforce Hancock and Getty; but the density of the intervening forest was such that, there being no road to march upon, they did not get up with the head of column until night, and bivouacked where they were without getting into position.

During the afternoon Sheridan sent Gregg's division of cavalry to Todd's Tavern in search of Wilson. This was fortunate. He found Wilson engaged with a superior force under General Rosser, supported by infantry, and falling back before it. Together they were strong enough to turn the tables upon the enemy and themselves become aggressive. They soon drove the rebel cavalry back beyond Corbin's Bridge.

Fighting between Hancock and Hill continued until night put a close to it. Neither side made any special progress.

After the close of the battle of the 5th of May my orders were given for the following morning. We knew Longstreet with 12,000 men was on his way to join Hill's right, near the Brock Road, and might arrive during the night. I was anxious that the rebels should not take the initiative in the morning, and therefore ordered Hancock to make an assault at 4.30 o'clock. Meade asked to have the hour changed to six. Deferring to his wishes as far as I was willing, the order was modified and five was fixed as the hour to move.

Hancock had now fully one-half of the Army of the Potomac. Wadsworth with his division, which had arrived the night before, lay in a line perpendicular to that held by Hill, and to the right of Hancock. He was directed to move at the same time, and to attack Hill's left.
