APRIL 5, 1865-6.40 p.m.

Major-General WARREN,

Petersburg:

I was coming over to see you in the morning by the railroad. I think it must be General Collis' infantry brigade that is to be relieved here. My command, besides the defenses, is the Engineer Brigade and field depot of the Army of the Potomac, which will not include General Hartsuff's command. Is it not so?

H. W. BENHAM.

PETERSBURG, April 5, 1865.

General BENHAM:

General Warren desires me to say that you will be under the orders of General Meade, and not under the orders of General Hartsuff.

Respectfully,

E. B. COPE,

Major and Aide-de-Camp.
