BATTLE OF SPOTTSYLVANIA--HANCOCK'S POSITION--ASSAULT OF WARREN'S AND WRIGHT'S CORPS--UPTON PROMOTED ON THE FIELD--GOOD NEWS FROM BUTLER AND SHERIDAN.
The Mattapony River is formed by the junction of the Mat, the Ta, the Po and the Ny rivers, the last being the northernmost of the four. It takes its rise about a mile south and a little east of the Wilderness Tavern. The Po rises south-west of the place, but farther away. Spottsylvania is on the ridge dividing these two streams, and where they are but a few miles apart. The Brock Road reaches Spottsylvania without crossing either of these streams. Lee's army coming up by the Catharpin Road, had to cross the Po at Wooden Bridge. Warren and Hancock came by the Brock Road. Sedgwick crossed the Ny at Catharpin Furnace.
Burnside coming by Aldrich's to Gates's house, had to cross the Ny near the enemy. He found pickets at the bridge, but they were soon driven off by a brigade of Willcox's division, and the stream was crossed. This brigade was furiously attacked; but the remainder of the division coming up, they were enabled to hold their position, and soon fortified it.
About the time I received the news of this attack, word came from Hancock that Early had left his front. He had been forced over to the Catharpin Road, crossing the Po at Corbin's and again at Wooden Bridge. These are the bridges Sheridan had given orders to his cavalry to occupy on the 8th, while one division should occupy Spottsylvania. These movements of the enemy gave me the idea that Lee was about to make the attempt to get to, or towards, Fredericksburg to cut off my supplies. I made arrangements to attack his right and get between him and Richmond if he should try to execute this design. If he had any such intention it was abandoned as soon as Burnside was established south of the Ny.
The Po and the Ny are narrow little streams, but deep, with abrupt banks, and bordered by heavily wooded and marshy bottoms--at the time we were there--and difficult to cross except where bridged. The country about was generally heavily timbered, but with occasional clearings. It was a much better country to conduct a defensive campaign in than an offensive one.
By noon of the 9th the position of the two armies was as follows: Lee occupied a semicircle facing north, north-west and north-east, inclosing the town. Anderson was on his left extending to the Po, Ewell came next, then Early. Warren occupied our right, covering the Brock and other roads converging at Spottsylvania; Sedgwick was to his left and Burnside on our extreme left. Hancock was yet back at Todd's Tavern, but as soon as it was known that Early had left Hancock's front the latter was ordered up to Warren's right. He formed a line with three divisions on the hill overlooking the Po early in the afternoon, and was ordered to cross the Po and get on the enemy's flank. The fourth division of Hancock's corps, Mott commanding, was left at Todd's when the corps first came up; but in the afternoon it was brought up and placed to the left of Sedgwick's--now Wright's--6th corps. In the morning General Sedgwick had been killed near the right of his intrenchments by rebel sharpshooters. His loss was a severe one to the Army of the Potomac and to the Nation. General H. G.
Wright succeeded him in the command of his corps.
Hancock was now, nine P.M. of the 9th of May, across the left flank of Lee's army, but separated from it, and also from the remainder of Meade's army, by the Po River. But for the lateness of the, hour and the darkness of the night he would have attempted to cross the river again at Wooden Bridge, thus bringing himself on the same side with both friend and foe.
The Po at the points where Hancock's corps crossed runs nearly due east. just below his lower crossing--the troops crossed at three points--it turns due south. and after passing under Wooden Bridge soon resumes a more easterly direction. During the night this corps built three bridges over the Po; but these were in rear.
The position assumed by Hancock's corps forced Lee to reinforce his left during the night. Accordingly on the morning of the 10th, when Hancock renewed his effort to get over the Po to his front, he found himself confronted by some of Early's command, which had been brought from the extreme right of the enemy during the night. He succeeded in effecting a crossing with one brigade, however, but finding the enemy intrenched in his front, no more were crossed.
Hancock reconnoitred his front on the morning of the 10th, with the view of forcing a crossing, if it was found that an advantage could be gained. The enemy was found strongly intrenched on the high ground overlooking the river, and commanding the Wooden Bridge with artillery. Anderson's left rested on the Po, where it turns south; therefore, for Hancock to cross over--although it would bring him to the same side of the stream with the rest of the army--would still farther isolate him from it. The stream would have to be crossed twice in the face of the enemy to unite with the main body. The idea of crossing was therefore abandoned.
Lee had weakened the other parts of his line to meet this movement of Hancock's, and I determined to take advantage of it. Accordingly in the morning, orders were issued for an attack in the afternoon on the centre by Warren's and Wright's corps, Hancock to command all the attacking force. Two of his divisions were brought to the north side of the Po. Gibbon was placed to the right of Warren, and Birney in his rear as a reserve. Barlow's division was left south of the stream, and Mott of the same corps was still to the left of Wright's corps. Burnside was ordered to reconnoitre his front in force, and, if an opportunity presented, to attack with vigor. The enemy seeing Barlow's division isolated from the rest of the army, came out and attacked with fury. Barlow repulsed the assault with great slaughter, and with considerable loss to himself. But the enemy reorganized and renewed the assault.
