 When war came, Davis, against Benjamin's advice, imposed an embargo on exports of cotton to nations that had not recognized the Confederate government, hoping to force such relations, especially with Britain and France. As the Union was attempting to prevent cotton from being exported from Confederate ports by a blockade and other means, this played to a certain extent into the hands of Lincoln and his Secretary of State, William H. Seward. Additionally, when the war began, Britain had a large surplus of cotton in warehouses, enough to keep the mills running at least part-time for a year or so. Although many prominent Britons believed the South would prevail, there was a reluctance to recognize Richmond until it had gained the military victories to put its foe at bay. Much of this was due to hatred of slavery, though part of it stemmed from a desire to remain on good terms with the U.S. government — due to a drought in 1862, Britain was forced to import large quantities of wheat and flour from the United States. Also, Britain feared the expansionist Americans might invade the vulnerable Canadian colonies, as Seward hinted they might.
