According to Raul Hilberg's final scholarly work on Auschwitz: up to 175,000 Jews, including 38,571 from the Netherlands, were deported to Auschwitz up until December 31, 1942.1 The Germans had supposedly been gassing Jews there since January 1942, initially in the modified morgue in Auschwitz I, but by the middle of the year operations had switched to two modified peasant cottages in Birkenau which "were the sites of systematic and unceasing murder of Jews who were brought in mass transports from various German-occupied European countries."2
As early as January 1942, the BBC had been broadcasting to Continental Europe radio programmes recorded in the United States by Thomas Mann in which he mentioned the experimental gassings of 400 Jews deported from the Netherlands.3 By June "the BBC began to refer to the gassings in Poland," and the 6pm news on BBC Home Service on July 9, 1942 stated: "Jews are regularly killed by machine-gun fire, hand grenades—and even poisoned by gas." Anne Frank supposedly mentioned hearing on the English radio that Jews were being gassed whilst writing about the rounding-up and deportation of Dutch Jews in an October 9 diary entry.4
Despite all of that, the German Foreign Ministry's representative in the Hague: Otto Bene, wrote in a November 16, 1942 report:"The Dutch population are used to the deportation of the Jews. They are making no trouble whatsoever. Reports from Rauschwitz [recte Auschwitz] camp sound favorable. Therefore the Jews have abandoned their doubts and more or less voluntarily come to the collecting points."5

Pomerans et. al., The Diary of Anne Frank: The Revised Critical Edition, NY: Doubleday, 2003, p.290; British revisionist Simon Sheppard argues that: "the published Diary of Anne Frank, covering the period 12 June 1942 to 1 August 1944, was actually written between 20 May 1944 and 1 August 1944. It consists of a substantially revised compilation of her earlier diary and was described by her as a novel" in "On the Book of Frank" by S.
