One of the greatest “what ifs” in human history involves the “Trent Affair” of the American Civil War. As you might know, the Confederate states were eager to get official recognition from European countries. This would not only give the Confederate states a huge prestige boost, it would also have given them access to loans of money, war materiel and possibly even troops to fight the Northern states. To help secure this recognition, the CSA dispatched James M. Mason of Virginia and John Slidell of Louisiana to Havana, Cuba, where they boarded the British ship R.M.S. Trent en route to meetings with British and French authorities respectively. However, on November 8, 1861 the Trent was boarded by sailors from the USS San Jacinto. The two Confederate diplomats were arrested and taken to Boston while the Trent was allowed to continue to Britain.
Not surprisingly, this action set off a firestorm of controversy in the United Kingdom. British Prime Minister Lord Palmerston is alleged to have begun an emergency cabinet meeting about the affair by throwing his hat on the table and declaring, “I don’t know whether you are going to stand this, but I’ll be damned if I do”. Public opinion in the UK tended to favor the South over the North in the conflict, and support for the Confederacy was even greater amongst the people that had the means of making their opinion count: the gentry and aristocracy. As you probably know, one of Britain’s key industries at this time was the export of cotton and wool fabric, and the overwhelming majority of the raw cotton sent through British looms came from the American South. Not surprisingly then, support for the Confederate states was nearly unanimous within this key British constituency. A letter was therefore quickly dispatched to the American Secretary of State demanding the release of the Confederate diplomats as well as an apology to Britain for this blatant disregard for maritime law. The British also began ramping up on war materiel such as boats, guns and ammunition, and they also began moving troops to areas where they could be quickly dispatched… to go to war against the United States.
