This done, he deemed it prudent to
retire to Hanovertown. The next morning he again marched to Hanover
Station, and there ascertained that a strong force of the enemy,
consisting of infantry, cavalry, and artillery, was posted at the
South Anna bridges. These troops had gone there from Richmond en
route to reinforce Lee. In the face of this impediment Custer's
mission could not be executed fully, so he returned to Baltimore
crossroads.

The whole command was drawn in by noon of the 22d, and that day it
crossed the Pamunkey by Merritt's reconstructed bridge, marching to
Ayletts, on the Mattapony River, the same night. Here I learned from
citizens, and from prisoners taken during the day by scouting parties
sent toward Hanover Court House, that Lee had been, forced from his
position near Spottsylvania Court House and compelled to retire to
the line of the North Anna. I then determined to rejoin the Army of
the Potomac at the earliest moment, which I did by making for
Chesterfield Station, where I reported to General Meade on the 24th
of May.

Our return to Chesterfield ended the first independent expedition the
Cavalry Corps had undertaken since coming under my command, and our
success was commended highly by Generals Grant and Meade, both
realizing that our operations in the rear of Lee had disconcerted and
alarmed that general so much as to aid materially in forcing his
retrograde march, and both acknowledged that, by drawing off the
enemy's cavalry during the past fortnight, we had enabled them to
move the Army of the Potomac and its enormous trains without
molestation in the manoeuvres that had carried it to the North Anna.
Then, too, great quantities of provisions and munitions of war had
been destroyed--stores that the enemy had accumulated at sub-depots
from strained resources and by difficult means; the railroads that
connected Lee with Richmond broken, the most successful cavalry
leader of the South killed, and in addition to all this there had
been inflicted on the Confederate mounted troops the most thorough
defeat that had yet befallen them in Virginia.

When the expedition set out the Confederate authorities in Richmond
were impressed, and indeed convinced, that my designs contemplated
the capture of that city, and notwithstanding the loss they sustained
in the defeat and death of Stuart, and their repulse the succeeding
day, they drew much comfort from the fact that I had not entered
their capital
