But due to the various concentration camp massacres following Germany's occupation of Poland, Polish casualties suddenly increased by millions.
Currently, Poland's casualties rank ahead of France and behind only Russia, the Island Nation, and Germany.
In this respect, Poland's situation is incomparable to that of Austria. As another nation fully occupied by Germany, most of Austria's population has been recognized by the German government, and the Czech Region is already Germany's second most important industrial strongpoint, naturally making massacres there unlikely.
Taking into account the military personnel numbers and casualty figures of the various nations, the ones who truly suffered terrible losses are only the fully occupied countries of Poland and Austria.
Even Russia, with the highest number of casualties, did not suffer a crippling blow in the war, but rather a flesh wound, so to speak.
