Well, Derleth- I disagree about the Brit navy- the Ironclads would have blown the entire 'wooden wall" away with a minimum of fuss, and a large # of “jack tars” meeting Davey Jones. Remember, we didn’t just have the Monitor, we had dozens & dzoens of Ironclads- of which the Monitor was one of the first and the weakest. The “double-turrented” monitors were espec powerful. The Virginia, which was poorly built, had a field day against the Union wood navy.
Note also- there is really no way the “South could have won the War”- militarily that is. If Lincoln had not been Prez, maybe a diplomatic compromise might have been reached- but I think that would have had the South re-joinig the Union, but with Slavery guarenteed.
Bryan makes a good point- there are literally thousands of 'what if the South had won" stories out there- but few “what if the North had won a fast clean victory”? - which was FAR more likely, and hasn’t been discussed much.
Rex- phrases like “universally considered the greatest book on Slavery, written by the greatest historian of the period to draw breath”- absolutely cry out to be challenged- especially as I have not heard of either, and I am quite well read. Esp since the author is a “marxist”, you might think that some of the dudes on the right, or some of the Southern Apologist critics & historians, might just disagree a mite.
I am afraid Mr Turteldove, being somewhat of a Southern Apologist, is wrong about Slavery ending soon after. It was in their damn Consitution for gods sake. If the Confederate Central Government had tried it- many of the Southern States would have seceded from the Confederacy.
IMHO, what would have happened, some 2.3 generations after the War, was a law that kept all current slaves in place, but made all new children free, and possibly stopped the buying & selling of slaves. So, around WWI, slavery would have been starting to be phased out, with most of the “peculiar institution” gone by WWII. Note that then -IMHO- there might not have been a WWII (as we know it), as the French terms of Victory in WWI mostly led to WWII, and the vast change in American involvement would have had WWI end in a bloody draw. Here, I agree with Turtledove- this might have forced the North into the Kaisers camp.
Of course, there might well have been some sort of “WWII”, but the players would have been different. I surmise a Pacific war with Japan against the French, Dutch, & Brits- which Japan would have won. In the general confusion, there could well have been some wars break out in Central Europe, also.
