AUGUST 1, 1863-2. 40 pm.

Major-General Howard,

Commanding Eleventh Corps:

I am instructed by the major-general commanding to say that you have misapprehended the order of yesterday; that it was designed you should occupy the four points named with about a regiment each, from which several small detachments could be thrown out, and so posted that patrols between them could be made with sufficient frequency to deter bushwhackers and others from passing between them; that it was intended yo should still hold the points on the railroad heretofore held by you, the main force of the corps being posted in the vicinity of Warrenton Junction. j His disposition of your corps the major-general commanding still desires you to make.

Very respectfully, your obedient servant,

A. A. Humphreys,

Major-General, Chief of Staff.
