It required until that time for the 9th corps to get up and into position.

The attack was made as ordered, and the fighting continued with but little intermission until six o'clock the next morning, and resulted in our carrying the advance and some of the main works of the enemy to the right (our left) of those previously captured by General Smith, several pieces of artillery, and over four hundred prisoners.
The 5th corps having got up, the attacks were renewed and persisted in with great vigor on the 17th and 18th, but only resulted in forcing the enemy into an interior line, from which he could not be dislodged.

The advantages of position gained by us were very great.

The army 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in front of Bermuda Hundred, expecting, no doubt, to get troops from north of the James to take the place of those withdrawn before we could discover it.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About two o'clock in the afternoon General Butler was forced back to the line the enemy had withdrawn from in the morning.
