HEADQUARTERS THIRD DIVISION, CAVALRY CORPS, Summit Point, August 18, 1864-10.45 a.m.

Brigadier-General McINTOSH,
Commanding First Brigade:

GENERAL: According to directions of the chief of cavalry, if you have not already done so, you will without delay strengthen your picket at the stone church on the road over which we advanced this morning, to a full regiment, under a good and responsible officer, and will advance it to the crossing of the Opequon Creek. Having arrived there it will post itself in a most advantageous manner for the purpose of holding that place. The commanding officer will keep pickets out well beyond the crossing and be instructed to communicate frequently with these headquarters; he must also hold his position as long as possible.

By command of Brigadier-General Wilson:

L. SIEBERT,
