I've published my official review of R. J. Rummel's Democide: Nazi Genocide and Mass Murder.

This book gives a detailed analysis of estimates available for the killing of civilians by Nazi Germany. It breaks it all down by targeted groups and country citing every source used. I highly recommend this book to anyone trying to get a better understanding of Hitler and Nazi Germany.

Interesting book. If it came out in 1992, I wonder why I've never heard of it.

You mentioned "murdered hostages". Does this include POWs that were killed by the Nazis? If so, what does kind of estimates does the author give for America POWs killed by the Nazis?

That does include POWs. He gives an estimate of 2,038 US POWs killed by Nazi Germany.

Curious, why the interest?
