now I understand, there were no Russians or Germans involved, only communists and Nazi (probably Polish nazi and communists, he?)
everything sorted out.
Well... as I'm Russian, I would rather try to advocate the Germans. I suggest that you read "the Coming of 3rd Reich" by R. Evans. As you read the book, it sometimes seems as if there was something supernatural that enthroned Hitler for practically nothing spelled troubles.
Ironically the commies were the only tangible counterbalance for the nazies within the Germany.
I just want to say that most of the time there're certain people to blame, not folks.
What about the Palace`s art?
It's not bad, ressembles that of Moscow metro... but... it's Soviet. It's just beyond my grasp how pious Poles could exchange godly art to the atheistic one.
Of course, you do realise, if they had been preserved till today, they would be run as Catholic churches.
It'd been Catholic for about three years when Germans entered the town in 1915. I don't honestly care for I don't make disctinctions between the two branches of Christianity. That's perhaps cause I'm quite cold towards the Church.
