I agree any land taken away from Germany will suffer population transfer. That is sadly unavoidable and still seen acceptable in that era.
Yep. There are things I've really hated writing about in this (e.g. Operation Reinhardt), but there just isn't any way to write this sort of story without including them.
Another question about the lands that Poland will take from Germany... iOTL, I believe that Stalin was fine with Poles (Catholics only???) who had lived in pre-war Polish area East of the Curzon line moving to the lands that Poland took from Germany. This greatly reduced the number of Poles in the Soviet Union and they moved to a nation was a fellow Communist state. What does Stalin do with them iTTL.
I've not decided what to do with them yet - so far I've just handwaved it as being the same as happened during 1940-41 in OTL. Postwar I'll have to come up with something though.
Unless Hungary's getting to keep its annexations there's little reason for the allies to even consider giving the land to the Czechs rather than Poland.
My assumption is that we're going to see some hybrid of the 1814 Congress of Vienna and 1948 Hague Congress to thrash out what to do with e.g. the Hungarian annexations. They aren't going to be allowed to just stand, but at the same time the Entente trying to reverse them by main force isn't going to fly.
I am pretty sure Poland is guaranteed to get East Prussia (the fig leaf above is more than enough at the now, though Poland becoming a constitutional monarchy again would be interesting) and at least a chunk of upper Silesia. In my previous post, which I clearly was not so clear in, I was more suggesting that since the Czech historic claim to Silesia is much stronger, if Poland is getting a piece it makes a certain amount of sense that the Czechs do as well. I did not intend to suggest that all of Silesia go to the Czechs. I had not considered the issue of mountains, admittedly.
I don't think they even care about the fig leaf. Germany has been the cause of Poland losing vast amounts of territory and has murdered millions of Polish citizens, in the circumstances compensating Poland with formerly German territory will be seen as natural justice.
Making my way slowly through original thread. While I like the idea... the execution is not best. Complete reliance on "its all that bumbling Hitler's fault" excuse. Germans being so dumb and incapable of learning and repeating the same mistake over and over like caricatures of Red Army in '41 and '42. Huge percentage of TL being dedicated to British military procurement
<shrugs> I'm a professional engineer (CEng FIMechE), not a professional writer - so I make no apologies for my areas of interest bleeding over into the writing. If you want an enormous WW2 timeline which focuses on something else, feel free to go and write it - I'd be interested to read it.
I would also note that while at a tactical level the Germans were pretty competent, at an operational level they were not (getting incredibly lucky on a number of occasions - something I haven't allowed them to be here) and at a strategic level they couldn't find their arse with both hands and a map. What happened here is essentially what the Generalstab was expecting as of early 1940 - they knew that the invasion of France was a massive gamble and also their only chance to win.
I know that isn't everyone's cup of tea but considering the thread's deducted to different fighting vehicles, equipment etc I have to disagree this is a design fault with the author but a matter of your personal taste.
It's also a case of writing what you know. If I tried to write something else I suspect it would be far worse, and I'd certainly have far less interest in writing it.
