War loomed in late 1861 between the US and Britain over the
Affair, which began when US Navy personnel boarded the British ship
and seized two Confederate diplomats. However, London and Washington smoothed this over after Lincoln released the two men.
Prince Albert left his deathbed to
issue diplomatic instructions to
Lord Lyons during the
Trent Affair. His request was honored, and, as a result, the British response to the US was toned down, helping avert war. In 1862, the British government considered mediating between the Union and Confederacy, though such an offer would have risked war with the US. British prime minister
Lord Palmerston reportedly read
Uncle Tom's Cabin three times when deciding what his decision would be.
