Now this is NOT ASB.
King Mongkut of Siam sent a letter to President James Buchanan, offering to send domesticated Elephants to The United States to use for transportaion and to help move large objects in construction/travel etc. The letter took so long to arrive that by the time it got there, Abraham Lincoln was in office. Lincoln sent a reply explaining that the steam engine could do the work that an elephant could, and thus no elephants were needed.
There is also a legend that states that the letter also offered war elephants in case The USA ever needs them.
So here is my POD. The British and The French come to the aid of The CSA (similar to TL 191). Lincoln then sends a reply accepting the offer. So just when the USA is on the edge of defeat, the Elephants arrive. So the British bring in Elephants from India and The French from Indo-China. So basically the US Civil War becomes The Great Elephant Wars.
So is this idea plausable? And if it is, who will win the war. The US-Siamese or the CS-British-French? And how would this affect history?
