Thanks for the interesting walk.
I would like to make some small clarifications
The occupation began with the invasion of Polish territory by German troops on September 1, 1939, and ended in 1945, when the Red Army, after lengthy battles, drove the German occupiers out of Poland.
The Germans captured Poland in less than three months; Soviet troops would not have had time to help even if they wanted to.
