Gouverneur K. Warren to Andrew A. Humphreys, July 29, 1864
July 29, 1864—4 p. m. Major-General HUMPHREYS Chief of Staff: GENERAL: I have received the programme order for operations tomorrow. I think the minimum of troops that I can depend upon holding my front line with is Griffin’s division, which forms a single line of battle, with one brigade of General Cutler’s. This will leave me one brigade of General Cutler’s, and General Ayres’ division, at least, to support General Burnside. If I can withdraw the most of my picketline, and abandon the southernmost redoubt on the plank road I can also have two brigades of General Crawford to aid General Burnside. I would like special instructions on this point. In the event of success the division of Crawford would be well posted to follow up along the plankroad. I am going to consult with General Burnside as to the cooperation he wishes me to give.
Respectfully,
Major-General.
HEADQUARTERS ARMY OF THE Potomac,
July 29, 1864—5.40 p. m.
Your dispatch of 4 p. m. received, and the commanding general directs the withdrawal of your troops to-night from the southernmost
redoubt and beyond, south of the large redoubt on the plank road. The
pickets should remain, and, if forced back, might occupy the works
