Colonel G. M. L. JOHNSON,
Thirteenth Indiana Cavalry, Commanding Cavalry Brigade:

COLONEL: You will establish the camp of your brigade at Starke's Landing, and will concentrate at that place as soon as possible all the detachments that are now absent. The camp should be established at least a mile in front (east) of the landing, leaving sufficient room on your right for the remainder of General Knipe's division, and on your left for the command of General Lucas (about 2,500 strong), which may be expected this evening or to-morrow morning. You will cover the front of your lines by pickets so far advanced as to give you timely notice of the approach of any rebel force. In addition to this, you will keep the country between the bay and Perdido River clear of all scouting or raiding parties of the enemy. I inclose a sketch of the country between the Escambia and Mobile Bay and a military map of Alabama and West Florida.
