HEADQUARTERS ARMY OF THE POTOMAC, PROVOST-MARSHAL-GENERAL'S DEPARTMENT,

August 7, 1864.

Major-General HUMPHREYS:

Three citizen refugees were forwarded to these headquarters this morning, who left Petersburg last evening at 6 o'clock. One of them was a miller, another a railroad employe, and the third a grocer-all citizens of the town. They left the city on a hand-car, going down the railroad as far as Reams' Station, where they were piloted into our lines by a negro. We think they are all right. They give but little information. They state that the Danville road has been in operation about two weeks, but that very little freight is received on it. On the Weldon road they have lately been bringing up large supplies of corn and bacon. They believe all three corps of the enemy to be her. What portion of them is on the north side of the Appomattox they are unable to say. They are not informed that any force has been sent away from here either to Early or to Georgia. Petersburg is nearly deserted,
