GENERAL ORDERS,
U. S. MISSISSIPPI SQUADRON, FLAG-SHIP BLACK HAWK, Numbers 197.
Off Mounth Red River, May 20, 1864.

The late order of the Secretary of the Treasury permits persons to bring cotton from within the lines of the enemy, but does not give permission to land more than a limited quantity of family supplies. All officers are directed not to interfere with the cotton trade, but to afford protection to vessels getting it off. No vessel will, however, be sent up any river, bayou, or creek for the purpose of aiding any cotton dealers, who, if they land in such places, do it at their own risk. All that will be required of commanders will be to see that no articles contraband of war are landed, and that steamers do not carry persons away from landing places without permits or passes either from naval officers or from military commanders.
