The Holocaust Hoax Exposed
and other misguided works misrepresent the truth.
A Red Cross report on deaths at the hands of Nazis in 1946 states only 200,000-300,000 died.
Ignoring the fact that this still shows Germans to be murderers, the actual findings are misrepresented by Holocaust deniers.
Wiki has an extensive discussion on this:
Holocaust deniers misrepresent and omit information contained in ICRC reports that contradict their claims. Critics argue that Richard Harwood in his "Did Six Million Really Die?" pamphlet could only claim that the ICRC had found no evidence of a policy to exterminate Jews by ignoring key sections of the 1948 report, where the ICRC explicitly states that the systematic extermination of Jews was Nazi policy.
Harwood disputed the notion that homicidal gas chambers were disguised as shower facilities by citing references in the report where ICRC officials inspected bathing facilities. He used their responses to argue that showers functioned as showers and were not part of a killing installation. However this is considered misrepresentation by critics, as the passage Harwood cited is in reference to Allied camps for civilians in Egypt and thus had nothing to do with Nazi concentration camps.
A letter from the Bad Arolsen International Tracing Service regarding only registered deaths at Nazi concentration camps. This and similar correspondence is frequently misrepresented as the absolute death toll of the Holocaust by deniers.
Harwood also claimed that Die Tat, a Swiss tabloid newspaper, published statistics that concluded the number of people who died in Nazi prisons and camps from 1939 to 1945 based on ICRC statistics was "300,000, not all of whom were Jews". The January 19, 1955 edition of Die Tat did indeed give a 300,000 figure, but this was only in reference to "Germans and German Jews" and not nationals of other countries. In a 1979 response to this pamphlet, the ICRC said that they have "never tried to compile statistics on the victims of the war", nor "certified the accuracy of the statistics produced by a third party", and state that the authors of such material have "falsified" both claims that the document originates from the ICRC and refers exclusively to Jews.
As well as in personal correspondence, the ICRC has also addressed this misrepresentation by several other means. In 1975, the ICRC wrote to the Board of Deputies of British Jews in London regarding Harwood's citations, stating:
The figures cited by the author of the booklet are based upon statistics falsely attributed to us, evidently for the purpose of giving them credibility, despite the fact that we never publish information of this kind.
