It damn well should be possible, if Lincoln leaves someone smarter in charge there then they can hold it with even a reduced amount of troops given the shitty CSA logistics in the area, as long as the Union can put up a moderate amount of fighting Bragg cannot take KentuckyWhat if the Union had been able to hold onto Kentucky after the War of Secession. Is it possible, how would it change the 2nd Mexican War and both Great Wars? Would it be worth it?
Definitely, Braggs logistics sucked, as long as they can last a week or so without being destroyed Bragg has to turn back to keep his army in munitionsLet's say that either Grant or Sherman are able to keep Bragg from taking Kentucky. Is that possible? Would Grant not end up a drunk, like in How few remain?
Honestly I don't see the US winning the Second Mexican War, even with someone competent in charge the US Army is still going to be small and funds starved, same with the Navy, that's politics, the British and French will still sweep the seas and start burning the coasts, so the US will still lose, on the other hand this time I see the USA still keeping Northern Maine so it will be a minor lossHow would the 2nd Mexican war be handled if Kentucky was still a U.S. State and their was someone competent in charge of the army. I think the north would have pushed the confederate army all the way to the Tennessee Georgia state line, before England and France joined the war. I think this would won the war for the North.
That might have saved the Republican party, but what it would have done to the relations between the U.S. and the C.S.A. Would the north consider that they have avenged themselves for the disaster 20 years earlier, would the C.S.A. be angry at England and France for not entering the war sooner, what about slavery, would the C.S.A. still have slavery? Would the south join the other side in the Great War or would they still fight alongside England and France? What about the north with a victory in the 2nd Mexican War, would they still join Germany in the Great War, or would they fight alongside C.S.A., England, and France, or would they remain neutral?
