Political mistakes by military or others.
It’s a long time I thought about this one.
I explain. In 1781, Rochambeau and Washington won the battle of Yorktown. Cornwallis, British General, offered his sword to Rochambeau, who declined, showing Washington.
Politically, the gesture was clear for both sides: The English surrendering to the French, quiet normal, one time I win, one time I loose, so a French victory implication is negation of the American troops, considered as auxiliaries.
For the French side, it implicated a clear recognition of the USA (future) as a new state, so the biggest lost of territory at the time for England.
In 1782, November, the Treaty of Paris made USA independent from UK.
However, the original French-American treaty of alliance stated that the two countries would not negotiate for peace separately. Against all pre-agreement not to do it, the American did and signed separate peace with the UK.
So the French couldn’t recover Canada, and even perhaps pats of India lost by Dupleix.
Now, if Rochambeau would have accepted the Cornwallis’ sword, Yorktown would have been a French victory, and then perhaps all history and geography would have been change. USA would have existed, by smaller, with Canada and Louisiana France should have been a major player (remember Louisiana went from Canadian’s borders to the coast and to the west, so no rush to west for gold, or under French or Spanish/Mexican control).
And perhaps no French Revolution, Louis the XVI would need to raise taxes, so to gather the Assemblee and to start the process which ended for him on the guillotine.
Do you guys have something similar, somewhere, in your history?
