So, as it says on the tin, I'm looking for some thoughts on if foreign countries intervened in the U.S. Civil War. Specifically, I was thinking the main foreign powers who would intervene would be France and the UK on the side of the Confederacy and Russia on the side of the Union. If anyone knows of any other powers who would be likely to intervene, feel free to mention them.
The point of divergence I had in mind was a more successful Confederate invasion of Maryland in 1862, starting with a victory for the South at Antietam. If any of you have any thoughts about this PoD, or have a better one in mind, feel free to say it.
First off, what were the prospects for the Union if foreign countries intervened in the U.S. Civil War? Could the Union still gain victory? How long would the war go?
I would really appreciate it if anyone had access to some good sources on the subject, such as the opinions of the different countries about the Civil War and their strengths and weaknesses. If anyone had a link to previous good AH.com Threads on this subject.
Thank you everyone!
