While the Sumter expedition was being got ready, still without sailing orders, a supplemental expedition was also preparing for the relief of Pickens. This was the business that Seward was contriving, that Lincoln would not explain, on April first. The order interfering with the Navy Department was designed to checkmate the titular head of the department. Furthermore, Seward had had the amazing coolness to assume that Lincoln would certainly accept his Thoughts and that the simple President need not hereinafter be consulted about details. He aimed to circumvent Welles and to make sure that the Sumter expedition, whether sailing orders were issued or not, should be rendered innocuous. The warship Powhatan, which was being got ready for sea at the Brooklyn Navy Yard, was intended by Welles for the Sumter expedition. One of those unread despatches signed by Lincoln, assigned it to the Pickens expedition. When the sailing orders from Welles were received, the commander of the Sumter fleet claimed the Powhatan. The Pickens commander refused to give it up. The latter telegraphed Seward that his expedition was "being retarded and embarrassed" by "conflicting" orders from Welles. The result was a stormy conference between Seward and Welles which was adjourned to the White House and became a conference with Lincoln. And then the whole story came out. Lincoln played the scapegoat, "took the whole blame upon himself, said it was carelessness, heedlessness on his part; he ought to have been more careful and attentive." But he insisted on immediate correction of his error, on the restoration of the Powhatan to the Sumter fleet. Seward struggled hard for his plan. Lincoln was inflexible. As Seward had directed the preparation of the Pickens expedition, Lincoln required him to telegraph to Brooklyn the change in orders. Seward, beaten by his enemy Welles, was deeply chagrined. In his agitation he forgot to be formal, forgot that the previous order had gone out in the President's name, and wired curtly, "Give up the Powhatan. Seward." This despatch was received just as the Pickens expedition was sailing. The commander of the Powhatan had now before him, three orders. Naturally, he held that the one signed by the President took precedence over the others. He went on his way, with his great warship, to Florida. The Sumter expedition sailed without any powerful ship of war. In this strange fashion, chance executed Seward's design.
