ON MADISON ROAD, [August - 1862]-11.58.

[General McDOWELL:]

Last report from cavalry pickets say small force of cavalry and infantry, not certainly more than a regiment, probably less, are retiring toward Madison.

Do you wish me to go any farther from the army? I am about 2 miles distant; the cavalry battalion 1 mile farther.

With respect,

Z. B. TOWER,

Brigadier-General.

Colonel SCHRIVER, Chief of Staff:

COLONEL: There is no doubt but they (the rebels) are massing their troops toward the right. Heavy columns moved down to the right yesterday, and all their movements seem to be in that direction-down toward Fairfax.
