...to rise up against the Germans. So no, don't tell me they were simply "having" to go through Poland to reach Germany.
Those two actions were not mutually exclusive. The Red Army would, of course, benefit from an uprising that is coordinated with them.
They were smart enough to know that the WU was coordinated against
them and militarily stupid. There is a simple rule in life: never yell at a perp who is ready to run away. AK violated this rule and made the Soviets unhappy. So they said, fu*ck you, a-holes. Have it your way. Your way turned out to be 200,000 dead Poles.
That's my point of view. What is yours? That AK wanted to assist the Soviets in killing Germans or, maybe, to be first as a political move.
You probably also ignorant of the fact there were far more NKVD divisions operating in post-ww2 Poland then eastern Germany.
I am happy to admit that we didn't see any NKVD or Red Army guys in my entire life in Poland till I left in 1966.
How many NKVD "divisions" were there in Poland at the peak? Where did they stay? Were they free to mingle?
A division is 10,000 men, as far as I know.
