w before dark, and after night-fall Hancock's
corps passed me and began crossing the pontoon-bridge about 2 o'clock
in the morning.

By daylight Hancock was across, the cavalry following. Soon a
portion of his corps attacked the enemy's works on the east side of
Bailey's Creek, and, aided by the cavalry moving on its right,
captured four pieces of artillery. This opened the way for Hancock
to push out his whole corps, and as he advanced by a wheel, with his
left as a pivot, the cavalry joined in the movement, pressing forward
on the New Market and Central or Charles City roads.

We did not go far before we found the enemy's infantry posted across
these two roads behind a strong line of intrenchments on the west
bank of Bailey's Creek. His videttes in front of Ruffin's house on
the New Market road were soon driven in on their main line, and the
high ground before the house was immediately occupied by Torbert and
Gregg, supported by Kautz's division. By the time the cavalry line
was formed the Confederate General Kershaw, with his own division of
infantry and those of Wilcox and Heath, advanced to attack us.
Directing the most of his troops against the cavalry, which was still
mounted, Kershaw drove it back some distance over the high ground.
When it reached the eastern face of the ridge, however, it was
quickly dismounted, and the men directed to lie down in line of
battle about fifteen yards from the crest, and here the onset of the
enemy was awaited. When Kershaw's men reached the crest such a
severe fire was opened on them, and at such close quarters, that they
could not withstand it, and gave way in disorder. They were followed
across the plain by the cavalry, and lost about two hundred and fifty
prisoners and two battle-flags. The counter attack against the
infantry by Torbert and Gregg re-established our line and gave us the
victory of Darbytown, but it also demonstrated the fact that General
Lee had anticipated the movement around his left flank by
transferring to the north side of the James a large portion of his
infantry and W. H. F. Lee's division of cavalry.

This development rendered useless any further effort on Hancock's
part or mine to carry out the plan of the expedition, for General
Grant did not intend Hancock to assault the enemy's works unless
there should be found in them but a very thin line of infantry which
could be surprised. In such event, Hancock was to operate so that
the cavalry m
