Sheridan's cavalry had had considerable fighting during the afternoon of the 7th, lasting at Todd's Tavern until after night, with the field his at the close. He issued the necessary orders for seizing Spottsylvania and holding the bridge over the Po River, which Lee's troops would have to cross to get to Spottsylvania. But Meade changed Sheridan's orders to Merritt--who was holding the bridge--on his arrival at Todd's Tavern, and thereby left the road free for Anderson when he came up. Wilson, who was ordered to seize the town, did so, with his division of cavalry; but he could not hold it against the Confederate corps which had not been detained at the crossing of the Po, as it would have been but for the unfortunate change in Merritt's orders. Had he been permitted to execute the orders Sheridan gave him, he would have been guarding with two brigades of cavalry the bridge over the Po River which Anderson had to cross, and must have detained him long enough to enable Warren to reinforce Wilson and hold the town.
Anderson soon intrenched himself--if indeed the intrenchments were not already made--immediately across Warren's front. Warren was not aware of his presence, but probably supposed it was the cavalry which Merritt had engaged earlier in the day. He assaulted at once, but was repulsed. He soon organized his men, as they were not pursued by the enemy, and made a second attack, this time with his whole corps. This time he succeeded in gaining a position immediately in the enemy's front, where he intrenched. His right and left divisions--the former Crawford's, the latter Wadsworth's, now commanded by Cutler--drove the enemy back some distance.
At this time my headquarters had been advanced to Piney Branch Church. I was anxious to crush Anderson before Lee could get a force to his support. To this end Sedgwick who was at Piney Branch Church, was ordered to Warren's support. Hancock, who was at Todd's Tavern, was notified of Warren's engagement, and was directed to be in readiness to come up. Burnside, who was with the wagon trains at Aldrich's on our extreme left, received the same instructions. Sedgwick was slow in getting up for some reason--probably unavoidable, because he was never at fault when serious work was to be done--so that it was near night before the combined forces were ready to attack. Even then all of Sedgwick's command did not get into the engagement. Warren led the last assault, one division at a time, and of course it failed.
Warren's difficulty was twofold: when he received an order to do anything, it would at once occur to his mind how all the balance of the army should be engaged so as properly to co-operate with him. His ideas were generally good, but he would forget that the person giving him orders had thought of others at the time he had of him. In like manner, when he did get ready to execute an order, after giving most intelligent instructions to division commanders, he would go in with one division, holding the others in reserve until he could superintend their movements in person also, forgetting that division commanders could execute an order without his presence. His difficulty was constitutional and beyond his control. He was an officer of superior ability, quick perceptions, and personal courage to accomplish anything that could be done with a small command.
Lee had ordered Hill's corps--now commanded by Early--to move by the very road we had marched upon. This shows that even early in the morning of the 8th Lee had not yet become acquainted with my move, but still thought that the Army of the Potomac had gone to Fredericksburg. Indeed, he informed the authorities at Richmond he had possession of Spottsylvania and was on my flank. Anderson was in possession of Spottsylvania, through no foresight of Lee, however. Early only found that he had been following us when he ran against Hancock at Todd's Tavern. His coming detained Hancock from the battle-field of Spottsylvania for that day; but he, in like manner, kept Early back and forced him to move by another route.
Had I ordered the movement for the night of the 7th by my left flank, it would have put Hancock in the lead. It would also have given us an hour or earlier start. It took all that time for Warren to get the head of his column to the left of Hancock after he had got his troops out of their line confronting the enemy. This hour, and Hancock's capacity to use his whole force when necessary, would, no doubt, have enabled him to crush Anderson before he could be reinforced. But the movement made was tactical. It kept the troops in mass against a possible assault by the enemy. Our left occupied its intrenchments while the two corps to the right passed. If an attack had been made by the enemy he would have found the 2d corps in position, fortified, and, practically, the 5th and 6th corps in position as reserves, until his entire front was passed. By a left flank movement the army would have been scattered while still passing the front of the enemy, and before the extreme right had got by it would have been very much exposed. Then, too, I had not yet learned the special qualifications of the different corps commanders. At that time my judgment was that Warren was the man I would suggest to succeed Meade should anything happen to that gallant soldier to take him from the field. As I have before said, Warren was a gallant soldier, an able man; and he was beside thoroughly imbued with the solemnity and importance of the duty he had to perform.
