To Count Coutu

Nice that your handle has changed.
If you are interested in history, have a look at the Warsaw uprising of 1944. In 2 months, the Waffen SS killed 165,000 Polish civilians (not Jews, they'd all been killed a few years earlier). That's 3x the US losses in Vietnam, so imagine a wall of Polish names 3 times the size of the US memorial wall in Washington. Now, that wasn't the biggest crime of the Waffen SS by a long way.
To make life easy, you don't need a book, go to Google Images and type in "waffen SS warsaw uprising".
