Just at this time Seward was engaged in forwarding a measure no doubt intended to secure British anti-slavery sympathy for the North, yet also truly indicative of a Northern temper toward the South and its “domestic institution.” This was the negotiation of a Slave-Trade treaty with Great Britain, by which America joined, at last, the nations agreeing to unite their efforts in suppression of the African Slave Trade. The treaty was signed by Seward and Lyons at Washington on April 7. On the next day Seward wrote to Adams that had such a treaty been ratified “in 1808, there would now have been no sedition here, and no disagreement between the United States and foreign nations[584],” a melancholy reflection intended to suggest that the South alone had been responsible for the long delay of American participation in a world humanitarian movement. But the real purpose of the treaty, Lyons thought, was “to save the credit of the President with the Party which elected him if he should make concessions to the South, with a view of reconstructing the Union[585]”—an erroneous view evincing a misconception of the intensity of both Northern and Southern feeling if regarded from our present knowledge, but a view natural enough to the foreign observer at the moment. Lyons, in this letter, correctly stated the rising determination of the North to restore the Union, but underestimated the rapid growth of an equal determination against a restoration with slavery. The real motive for Seward’s eagerness to sign the Slave Trade treaty was the thought of its influence on foreign, not domestic, affairs. Lyons, being confident that Russell would approve, had taken “the risk of going a little faster” than his instructions had indicated[586].
