In short, I originally had no intention of writing it, and I'm not even remotely an expert on the topic. I had some inkling of the conflicts, but when I started thinking about it, I became curious and did a bit of reading which resulted in that post.
What I'm now curious about is if in my ignorance and attempt at brevity and levity I missed any critical bits of Polish history, especially as relations and conflicts with Russia are concerned.
Any informed comments appreciated.
I mean, you could've added a bit about the Soviets totally fucking over the Polish with regards to the whole "invading" thing. You completely left out the fact that they had already secretly divided up Poland through the Molotov-Ribbentrop pact, and were planning to invade a week in advance without any reason to do so. Here's some background on that.
It all started with the Molotov-Ribbentrop Pact of 1939. Under a secret article of it, this was written in:
Article II. In the event of a territorial and political rearrangement of the areas belonging to the Polish state, the spheres of influence of Germany and the U.S.S.R. shall be bounded approximately by the line of the rivers Narev, Vistula and San.
What this means is, the Germans and Soviets would work together and had already divided up Poland, in the event that Poland was invaded by either power. Which, of course, it was going to be that same year...well, within about a week. It also included the non-aggression pact, of course.
Anyways, what happened was not just the Soviets refusing to aid the Polish. They invaded Poland from the east themselves, about 2 and a half weeks after the Germans did. By this point, the Polish defenses were considered pretty inconsequential, because the Soviet choice to invade Poland rather than assist it made it pretty clear where the loyalties lay.
One other thing: I think characterizing the Warsaw uprising as the largest resistance movement is a misrepresentation even of what Wikipedia is saying (where it seems you got the idea). It says:
The Uprising was the largest single military effort taken by any European resistance movement of World War II.
However, I think that's just single military efforts. I don't think it compares to the French Resistance Movement on the whole. The Wikipedia page on the subject estimates 9,000 wounded, 2,000 taken prisoner, and around 16,000 killed or missing (from German forces). At most, initially, only 50,000 were in the Polish resistance fighting. The Free French Forces according to Wikipedia had over 550,000 in 1944, which is the same year as the Warsaw Uprising. They had 400,000 or so before the Normandy landings, according to that article, and were definitely a resistance movement. I think they weren't a resistance movement in the sense of being an "uprising from within", but that doesn't detach from their being a resistance movement.
Not trying to diminish the Polish accomplishments; it does appear to be the single largest undertaking by a purely resistance movement that I know of, but to call it the largest resistance movement on the whole would be a little bit of an overstatement.
But that's all I've got; don't know enough about the rest, and no time for more research.
