This was the accomplishment of the first step contemplated in my
instructions to Butler. He was to act from here, looking to Richmond as
his objective point. I had given him to understand that I should aim to
fight Lee between the Rapidan and Richmond if he would stand; but should
Lee fall back into Richmond I would follow up and make a junction of the
armies of the Potomac and the James on the James River. He was directed
to secure a footing as far up the south side of the river as he could at
as early a date as possible.

Butler was in position by the 6th of May and had begun intrenching, and
on the 7th he sent out his cavalry from Suffolk to cut the Weldon
Railroad. He also sent out detachments to destroy the railroad between
Petersburg and Richmond, but no great success attended these latter
efforts. He made no great effort to establish himself on that road and
neglected to attack Petersburg, which was almost defenceless. About the
11th he advanced slowly until he reached the works at Drury's Bluff,
about half way between Bermuda Hundred and Richmond. In the mean time
Beauregard had been gathering reinforcements. On the 16th he attacked
Butler with great vigor, and with such success as to limit very
materially the further usefulness of the Army of the James as a distinct
factor in the campaign. I afterward ordered a portion of it to join the
Army of the Potomac, leaving a sufficient force with Butler to man his
works, hold securely the footing he had already gained and maintain a
threatening front toward the rear of the Confederate capital.

The position which General Butler had chosen between the two rivers, the
James and Appomattox, was one of great natural strength, one where a
large area of ground might be thoroughly inclosed by means of a single
intrenched line, and that a very short one in comparison with the extent
of territory which it thoroughly protected. His right was protected by
the James River, his left by the Appomattox, and his rear by their
junction--the two streams uniting near by. The bends of the two streams
shortened the line that had been chosen for intrenchments, while it
increased the area which the line inclosed.

Previous to ordering any troops from Butler I sent my chief engineer,
General Barnard, from the Army of the Potomac to that of the James to
inspect Butler's position and ascertain whether I could again safely
make an order for General Butler's movement in co-operati
