I just reviewed the subject site. Obviously, I was curious to find what info could be found about participation of Poland. It is hard to say if the site is an example of Anti-polonism, ignorance of history or just a slappy job done by half-wits who pretend to be "experts". I looked for mentioning of Polish forces in the west in France, Africa or Italy. I found big Zero. To make up for this ommission, I found elaborate description of "volunteers" to the Vermacht as Volksdeutschers. There was no mention that thousands of Poles residing in the territory anexed to the Reich were forced to German army against their will. Omission of our contribution to the war is compensated by an elaborate description of French resistance.
There is some space devoted to the Warsaw Uprising and in the table giving losses in population, it is stated that Poland lost over 19 percent. I tried to find the address where I could respond to this but I couldn't.
