HEADQUARTERS ARMY OF THE POTOMAC,
OFFICE OF PROVOST-MARSHAL-GENERAL,

June 21, 1864.

General HUMPHREYS:

Five prisoners, captured by General Hancock's staff who were out riding along the left of our line, had gone to a house opposite their position in line of battle, and are from Perrin's (Alabama) brigade, Anderson's division. They only make certain our knowledge of the arrival of A. P. Hill's and Longstreet's corps on our front on Saturday last. From certain facts which they tell me, it is quite sure that Heth's division is here, from which we have as yet had no prisoners; also Field's division, of Longstreet's corps, which they say is in reserve, and that Pickett's division lies between the Appomattox and the James Rivers. McLaws' division they cannot account for. they agree that Ewell's corps is nowhere near them, but say that it left them at Cold Harbor, and they have not sen it since. They think from all they have heard it has gone to Western Virginia. Anderson has been made a lieutenant-general, and now commands Longstreet's corps; and upon the return of Longstreet it is understood that Anderson will have a corps to be made up of Hoke's division, breckinridge's division, and one other not yet formed.

Very respectfully,

GEORGE H. SHARPE,

Colonel, &c.
