It is possible that Queen Victoria (because she allowed Prince Albert so much active involvement in her job) and Prince Albert were responsible for the North winning the Civil War. No, this is not a joke, nor is it an attempt to taunt Warren. I think, and sincerely hope, it is on topic.
In late 1861 two Confederate envoys were travelling to London on a British mail packet out of Havanna,
Trent. US warship
San Jacinto discharged a shell across
Trent's bow and when
Trent stopped, she was boarded by an officer with a large armed guard of marines. The CSA envoys and their secretaries were removed and taken to the USA.
The full story is complicated and long, but to say the least Britain was not impressed with what had occurred, it amounting to a breach of international law. Prince Albert was very ill but also very concerned and recorded the events in his diary on 28 November 1861.
One of Prince Albert's last formal acts, if not the last, was the amending of a Draft memorandum from British Foreign Secretary, Lord Russell, to the British Ambassador in Washington, Lord Lyons, changing its wording and tone from bellicose to conciliatory, which quite likely avoided a declaration of war between Britain the and USA. Had war with the USA eventuated, Britain would have undoubtedly recognised the CSA. The USA had sought the support of France in that event, but France declined. It is likely that the USA could not have maintained a war against both Britain and the CSA, and would have ended up recognising the CSA.
Albert died two weeks after drafting the amendments, which were accepted. Victoria later wrote in the margin, "This draft was the last the beloved Prince ever wrote, he was very unwell at the time & when he brought it to the Queen he said, "I could hardly hold my pen"'.
According to Cecil Woodham-Smith in her "
Queen Victoria, Her Life and Times - Volume 1, 1819-1861" (there was to be no Volume 2), "The importance of the Prince Consort's amendments cannot be exaggerated. England and the Northern States of America were on the verge of war".
A detailed account of the
Trent Affair can be found here:
The Trent Affair: How the Prince Consort Saved the United States The article includes more quotes from Queen Victoria, including her acknowledgment that the peaceful resolution was one which "her dear Angel much wished for", and her statement to the Prime Minister in January 1862 that, "The things of this world are of no interest to the Queen, beyond the satisfaction she must experience if Peace is maintained and this country is in prosperity: for
her thoughts are
fixed above."
I don't know what HM thought about President Lincoln, but Woodham-Smith records that both Queen Victoria and Prince Albert liked President Buchanan when he was American Minister in London.
