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
