Major-General WARREN,

Commanding Fifth Corps:

It may become necessary, in connection with the expected attack on Wright, to occupy strongly a line along the Jerusalem plank road. The commanding general directs that you make preparations at once to put your available batteries in position to silence the enemy's batteries near the Gregory house, which enfilade the plank road.

HEADQUARTERS FIFTH ARMY CORPS,
June 23, 1864.-4.40 p.m.

Major-General HUMPHREYS:

There are twenty-eight guns now that can fire at the vicinity of the Gregory house posted along my front. Twelve of these belong to the Second Corps, which I will replace with mine at dark this evening, if they will withdraw them. I can get eight more guns in positions without much danger to-night, or sooner, if necessary, and take the musketry which they will draw on them in doing it. I think twenty-eight guns will silence the enemy if it can be done, but I doubt if we can do it on our front, for I think the battery is located over the ridge in a hollow on the west side and hard for us to see or reach.

G. K. WARREN,

Major-General of Volunteers.
