This booklet is a reprint of the various short reports that the American Army sent home on Dachau concentration camp when they liberated it in 1945. As a source, it is very interesting; how did the liberators react to the camp they found? What was their impression of the Germans who lived in the town of Dachau?
As can be expected from a report written early after the war, there are many mistakes in the reports. This would not have been a problem if the book had been properly edited. Unfortunately, someone who is not very knowledgeable on the subject edited the book. There are many mistakes in the German quotations. The camp is also wrongly referred to as a death camp. Death camps differed from concentration camps in that people did not work there, but were killed immediately after arrival. These camps only existed in Poland. The Dachau gas chamber is described but it is now widely accepted that this chamber was hardly (possibly never) used to kill people. That the editor fails to point this out is not just negligent, but it also gives ammunition to the so-called revisionists or holocaust deniers who claim that gas chambers were never in use. They often use Dachau as an illustration of the "false" impression that there were gas chambers.
There are other illustrations of the lack of insight of the editor. For instance, the report of the former mistress of Rudolf Hoess camp commandant of Auschwitz. Her name is only given abbreviated, while there are other reports on her, giving her name as Eleonore Hodys, for instance Hermann Langbeins book People in Auschwitz. This book also offers more information on the affair. Without a further introduction, Hodys' testimony makes little sense at it is on Auschwitz concentration camp.
For the professional historian it can be a valuable source of information, but general readers should avoid this book. It is a bad introduction on concentration camps for the non-professional. Many other books offer more accurate information on Dachau and other concentration camps.
