HEADQUARTERS U. S. TRANSPORT SHIP ATLANTIC,
April 11, 1861.
Lieut. J. ST. C. MORTON, Fort Jefferson, Tortugas:
SIR: You will act in concert with Major Arnold, commanding the harbor of the Tortugas, in preparing with the least possible delay projects for the complete temporary defense and occupation of the whole harbor of the Tortugas. The orders issued to Major Arnold, which he will exhibit to you, will impress you of the general project. Requisitions have been made upon the Ordnance Department for twenty to twenty-four heavy guns with barbette carriages and platforms of timber for these batteries. If these arrive they will be used. If ships arrive before them, the guns from the ships will be landed for this use, to be replaced by the Army pieces when received.
Orders have been issued to the commander of Fort Taylor to clear the brush and timber from a certain portion of the island of Key West. This brushwood will be used to make fascines, and will be transferred to the Tortugas upon requisition.
Relying upon your resources, energy, and intelligence for official professional aid in this matter,
I am, respectfully, your obedient servant,
HARVEY BROWN,
Colonel, Commanding.
