No Evidence Of Genocide
One of the most important aspects of the Red Cross Report is that it clarifies the true cause of those deaths that undoubtedly occurred in the camps toward the end of the war. Says the Report: "In the chaotic condition of Germany after the invasion during the final months of the war, the camps received no food supplies at all and starvation claimed an increasing number of victims. Itself alarmed by this situation, the German Government at last informed the ICRC on February 1st, 1945 ... In March 1945, discussions between the President of the ICRC and General of the S.S. Kaltenbrunner gave even more decisive results. Relief could henceforth be distributed by the ICRC, and one delegate was authorised to stay in each camp ..." (Vol. III, p. 83).
Clearly, the German authorities were at pains to relieve the dire situation as far as they were able. The Red Cross are quite explicit in stating that food supplies ceased at this time due to the Allied bombing of German transportation, and in the interests of interned Jews they had protested on March 15th, 1944 against "the barbarous aerial warfare of the Allies" (Inter Arma Caritas, p. 78). By October 2nd, 1944, the ICRC warned the German Foreign Office of the impending collapse of the German transportation system, declaring that starvation conditions for people throughout Germany were becoming inevitable.
In dealing with this comprehensive, three-volume Report, it is important to stress that the delegates of the International Red Cross found no evidence whatever at the camps in Axis occupied Europe of a deliberate policy to exterminate the Jews. In all its 1,600 pages the Report does not even mention such a thing as a gas chamber. It admits that Jews, like many other wartime nationalities, suffered rigours and privations, but its complete silence on the subject of planned extermination is ample refutation of the Six Million legend. Like the Vatican representatives with whom they worked, the Red Cross found itself unable to indulge in the irresponsible charges of genocide which had become the order of the day. So far as the genuine mortality rate is concerned, the Report points out that most of the Jewish doctors from the camps were being used to combat typhus on the eastern front, so that they were unavailable when the typhus epidemics of 1945 broke out in the camps (Vol. I, p. 204 ff) - Incidentally, it is frequently claimed that mass executions were carried out in gas chambers cunningly disguised as shower facilities. Again the Report makes nonsense of this allegation. "Not only the washing places, but installations for baths, showers and laundry were inspected by the delegates. They had often to take action to have fixtures made less primitive, and to get them repaired or enlarged" (Vol. III, p. 594).
