Wilmington, North Carolina, was the most important sea-coast port left to the enemy through which to get supplies from abroad, and send cotton and other products out by blockade-runners, besides being a place of great strategic value. The navy had been making strenuous exertions to seal the harbor of Wilmington, but with only partial effect. The nature of the outlet of Cape Fear River was such, that it required watching for so great a distance that, without possession of the land north of New Inlet, or Fort Fisher, it was impossible for the navy to entirely close the harbor against the entrance of blockade-runners.
To secure the possession of this land required the co-operation of a land force, which I agreed to furnish. Immediately commenced the assemblage in Hampton Roads, under Admiral D. D. Porter, of the most formidable armada ever collected for concentration upon one given point. This necessarily attracted the attention of the enemy, as well as that of the loyal North; and through the imprudence of the public press, and very likely of officers of both branches of service, the exact object of the expedition became a subject of common discussion in the newspapers both North and South. The enemy, thus warned, prepared to meet it. This caused a postponement of the expedition until the later part of November, when, being again called upon by Hon. G. V. Fox, Assistant Secretary of the Navy, I agreed to furnish the men required at once, and went myself, in company with Major-General Butler, to Hampton Roads, where we had a conference with Admiral Porter as to the force required and the time of starting. A force of six thousand five hundred men was regarded as sufficient. The time of starting was not definitely arranged, but it was thought all would be ready by the 6th of December, if not before. Learning, on the 30th of November, that Bragg had gone to Georgia, taking with him most of the forces about Wilmington, I deemed it of the utmost importance that the expedition should reach its destination before the return of Bragg, and directed General Butler to make all arrangements for the departure of Major-General Weitzel, who had been designated to command the land forces, so that the navy might not be detained one moment.
