Unknown to Joseph E. Johnston, July 20, 1861

General JosEPH EH. JOHNSTON, Manassas Junction, Va. :

GENERAL: You are a general in the Confederate Army, possessed of the power attaching to that rank. You will know how to make the exact knowledge of Brigadier-General Beauregard, as well of the ground as of the troops and preparation, avail for the success of the object in which you co-operate. The zeal of both assures me of harmonious action.
