Yes pretty good The invasion was over in 5 weeks, Lodz, Krakow, Lublin etc cities not destroyed.
2 million strong German army invaded (compared to 190 thousand Russian invading Ukraine). Massive, and also some fighting on the Eastern front against the Soviets !!!!

And 50 thousand Poles killed over those five weeks. Imagine if they'd defended the cities... it would have been, who knows exactly, but perhaps a million dead (and cities destroyed)
So yes it worked out well.
Maybe you have more to add then just one line in your posts, or maybe get educated first...
