"The news sounds unbelievable, but my sources are good. According to reports I have received, there is terrible grief in numerous Dutch Jewish families, in Amsterdam and other cities, where they mourn their sons who have met a horrifying death. Four hundred young Dutch Jews have been deported to Germany, to be used as guinea-pigs in experiments with poison gas. The virulence of this method of waging war, chivalrous and essentially German, a real Siegfried weapon, has proved itself against these young men, members of an inferior race. They are dead, killed for the sake of the New Order and to prove the skill of the master race in waging war. They were just about good enough for that purpose: they were Jews."As I said, this story sounds incredible, and over the whole world, people will have difficulty in believing it. [...] The tendency ... not to mention the inclination to regard such accounts as invented horror stories is widely diffused, and acts to the advantage of the enemy. But they are not mere stories—they are history. [...] "
In my opinion it is incorrect to describe Polish information regarding German atrocities as "trustworthy". The Poles, and to a far greater extent the Jews, tend to exaggerate German atrocities in order to stoke us up. They seem to have succeeded.Mr. Allen and myself have both followed German atrocities quite closely. I do not believe that there is any evidence which would be accepted in a Law Court that Polish children have been killed on the spot by Germans when their parents were being deported to work in Germany, nor that Polish children have been sold to German settlers. As regards putting Poles to death in gas chambers, I do not believe there is any evidence that this has been done. There may have been stories to this effect, and we have played them up in P.W.E. (Political Warfare Executive) rumours without believing that they had any foundation. At any rate there is far less evidence than exists for the mass murder of Polish officers by the Russians at Katyn. On the other hand we do know that the Germans are out to destroy the Jews of any age unless they are fit for manual labour.I think that we weaken our case against the Germans by publicly giving credence to atrocity stories for which we have no evidence. These mass executions in gas chambers remind me of the story of employment of human corpses during the last war for the manufacture of fat, which was a grotesque lie and led to true stories of German enormities being brushed aside as being mere propaganda.
