y then
proceeded to envelop Petersburg towards the South Side Railroad as far
as possible without attacking fortifications.

On the 16th the enemy, to reinforce Petersburg, withdrew from a part of
his intrenchment in front of Bermuda Hundred, expecting, no doubt, to
get troops from north of the James to take the place of those withdrawn
before we could discover it. General Butler, taking advantage of this,
at once moved a force on the railroad between Petersburg and Richmond.
As soon as I was apprised of the advantage thus gained, to retain it I
ordered two divisions of the 6th corps, General Wright commanding, that
were embarking at Wilcox's Landing, under orders for City Point, to
report to General Butler at Bermuda Hundred, of which General Butler was
notified, and the importance of holding a position in advance of his
present line urged upon him.

About two o'clock in the afternoon General Butler was forced back to the
line the enemy had withdrawn from in the morning. General Wright, with
his two divisions, joined General Butler on the forenoon of the 17th,
the latter still holding with a strong picket-line the enemy's works.
But instead of putting these divisions into the enemy's works to hold
them, he permitted them to halt and rest some distance in the rear of
his own line. Between four and five o'clock in the afternoon the enemy
attacked and drove in his pickets and re-occupied his old line.

On the night of the 20th and morning of the 21st a lodgment was effected
by General Butler, with one brigade of infantry, on the north bank of
the James, at Deep Bottom, and connected by pontoon-bridge with Bermuda
Hundred.

On the 19th, General Sheridan, on his return from his expedition against
the Virginia Central Railroad, arrived at the White House just as the
enemy's cavalry was about to attack it, and compelled it to retire. The
result of this expedition was, that General Sheridan met the enemy's
cavalry near Trevilian Station, on the morning of the 11th of June, whom
he attacked, and after an obstinate contest drove from the field in
complete rout. He left his dead and nearly all his wounded in our
hands, and about four hundred prisoners and several hundred horses. On
the 12th he destroyed the railroad from Trevilian Station to Louisa
Court House. This occupied until three o'clock P.M., when he advanced
in the direction of Gordonsville. He found the enemy reinforced by
infantry, behind well-constructed rif
