Major-General ORD,

Commanding Eighteenth Corps:

Your dispatch received. Can you concentrate your troops at any point, leaving a very thin line in the intrenchments, and attack if the enemy this off much more, or can you extend your line and relieve some part of Mott's corps, so that they can be sent toward the Weldon railroad? Mahone's division attacked Warren and was repulsed.
