Wilson preceded the Fifth Corps to Germania ford, and when it reached the river he made the crossing and moved rapidly by Wilderness Tavern, as far as Parker's Store, from which point he sent a heavy reconnoissance toward Mine Run, the rest of his division bivouacking in a strong position. I myself proceeded to Chancellorsville and fixed my headquarters at that place, whereon the 5th I was joined by Torbert's division.
Meanwhile, General Meade had crossed the Rapidan and established his headquarters not far from Germania ford. From that point he was in direct communication with Wilson, whose original instructions from me carried him only as far as Parker's Store, but it being found, during the night of the 4th, that the enemy was apparently unacquainted with the occurrences of the day, Meade directed Wilson to advance in the direction of Craig's Meeting House; leaving one regiment to hold Parker's Store. Wilson with the second brigade encountered Rosser's brigade of cavalry just beyond the Meeting House, and drove it back rapidly a distance of about two miles, holding it there till noon, while his first brigade was halted on the north side of Robinson's Run near the junction of the Catharpen and Parker's Store roads.
Up to this time Wilson had heard nothing of the approach of the Fifth Corps, and the situation becoming threatening, he withdrew the second brigade to the position occupied by the first, but scarcely had he done so when he learned that at an early hour in the forenoon the enemy's infantry had appeared in his rear at Parker's Store and cut off his communication with General Meade. Surprised at this, he determined to withdraw to Todd's Tavern, but before his resolution could be put into execution the Confederates attacked him with a heavy force, and at the same time began pushing troops down the Catharpen road. Wilson was now in a perplexing situation, sandwiched between the Confederates who had cut him off in the rear at Parker's store and those occupying the Catharpen road, but he extricated his command by passing it around the latter force, and reached Todd's Tavern by crossing the Po River at Corbin's bridge. General Meade discovering that the enemy had interposed at Parker's store between Wilson and the Fifth Corps, sent me word to go to Wilson's relief, and this was the first intimation I received that Wilson had been pushed out so far, but, surmising that he would retire in the direction of Todd's Tavern I immediately despatched Gregg's division there to his relief. Just beyond Todd's Tavern Gregg met Wilson, who was now being followed by the enemy's cavalry. The pursuing force was soon checked, and then driven back to Shady Grove Church, while Wilson's troops fell in behind Gregg's line, somewhat the worse for their morning's adventure.
When the Army of the Potomac commenced crossing the Rapidan on the 4th, General J. E. B. Stuart, commanding the Confederate cavalry, began concentrating his command on the right of Lee's infantry, bringing it from Hamilton's crossing and other points where it had been wintering. Stuart's force at this date was a little more than eight thousand men, organized in two divisions, commanded by Generals Wade Hampton and Fitzhugh Lee. Hampton's division was composed of three brigades, commanded by Generals Cordon, Young, and Rosser;
Fitzhugh Lee's division comprised three brigades also, Generals W. H.
F. Lee, Lomax, and Wickham commanding them.
Information of this concentration, and of the additional fact that the enemy's cavalry about Hamilton's crossing was all being drawn in, reached me on the 5th, which obviated all necessity for my moving on that point as I intended at the onset of the campaign. The responsibility for the safety of our trains and of the left flank of the army still continued, however, so I made such dispositions of my troops as to secure these objects by holding the line of the Brock road beyond the Furnaces, and thence around to Todd's Tavern and Piney Branch Church. On the 6th, through some false information, General Meade became alarmed about his left flank, and sent me the following note:
"HEADQUARTERS ARMY OF THE POTOMAC, "May 6, 1864.--1 o'clock P. M.
"MAJOR-GENERAL SHERIDAN, "Commanding Cavalry Corps "Your despatch of 11.45 a.m., received. General Hancock has been heavily pressed, and his left turned. The major-general commanding thinks that you had better draw in your cavalry, so as to secure the protection of the trains. The order requiring an escort for the wagons to-night has been rescinded.
"A. A. HUMPHREYS, "Major-General, Chief-of-Staff."
On the morning of the 6th Custer's and Devin's brigades had been severely engaged at the Furnaces before I received the above note.
They had been most successful in repulsing the enemy's attacks, however, and I felt that the line taken up could be held; but the despatch from General Humphreys was alarming, so I drew all the cavalry close in toward Chancellorsville. It was found later that Hancock's left had not been turned, and the points thus abandoned had to be regained at a heavy cost in killed and wounded, to both the cavalry and the infantry.
On the 7th of May, under directions from headquarters, Army of the Potomac, the trains were put in motion to go into park at Piney Branch Church, in anticipation of the movement that was about to be made for the possession of Spottsylvania Court House. I felt confident that the order to move the trains there had been given without a full understanding of the situation, for Piney Branch Church was now held by the enemy, a condition which had resulted from the order withdrawing the cavalry on account of the supposed disaster to Hancock's left the day before; but I thought the best way to remedy matters was to hold the trains in the vicinity of Aldrich's till the ground on which it was intended to park them should be regained.
