March 1 to 25.-Remained in camp near Petersburg, nothing unusual or worth of record taking place until the morning of the 25th.
March 25.-The enemy made a desperate assault on a portion of the Ninth Corps front, gaining a temporary advantage, at which time the First Division was ordered to the support of that corps, but before it arrived at the point of attack the enemy had been repulsed and the lost ground regained. As soon as its services were no longer needed the division was ordered back. In the afternoon of the same day an attack was made on the entrenched picket-line the enemy, in front of the corps, which was carried and held, some 650 prisoners being captured; not, however, without a desperate fight, in which the corps lost a considerable number of officers and men.
March 27.-Sharp picket-firing. At night the enemy regained one point of the line taken on the 25th. It was not thought advisable, however, to make any strenuous exertions to retake it.
