...The liquidation of the Jews in the Government-General began at Passover 1942. The first victims were the Jews of the city of Lublin, and shortly after that the Jews of the whole District of Lublin. They were evacuated to Belzec, and there they were killed in new gas-chambers that had been built specially for this purpose. The Jewish Underground newspapers gave detailed descriptions of this mass slaughter. But [the Jews of] Warsaw did not believe it! Common human sense could not understand that it was possible to exterminate tens and hundreds of thousands of Jews. They decided that the Jews were being transported for agricultural work in the parts of Russia occupied by the Germans. Theories were heard that the Germans had begun on the productivization of the Jewish lower-level bourgeoisie! The Jewish press was denounced and charged with causing panic, although the descriptions of the "rooting out" of the population corresponded accurately to the reality. Not only abroad were the crimes of the Germans received with disbelief, but even here, close by Ponary, Chelmno, Belzec and Treblinka, did this information get no hearing! This unjustified optimism developed together with the lack of information, which was the result of total isolation from the outside world and the experience of the past. Had not the Germans for two and a half years carried out many deportations of Jews from Cracow, from Lublin, from the Warsaw District and from the "Reich?" Certainly there had been not a few victims and blood had been shed during these deportations, but total extermination?
There were some people who believed it, however. The events at Ponary and Chelmno were a fact, but it was said "that was just a capricious act of the local authorities." For, after all, the German authorities in the Government-General did not have the same attitude to the ghettoes in the cities and the small towns, not until death brought an equal fate to all. More than once, in various places, the reaction to the information we had about the liquidation of the Jews was: "That cannot happen to us here.”
It was of course the Germans themselves who created these optimistic attitudes. Through two and a half years they prepared the work of exterminating the three and a half million Jews of Poland with German thoroughness. They rendered the Jewish masses helpless with the aid of individual killings, oppression and starvation, with the aid of ghettos and deportations. In years of unceasing experiments the Germans perfected their extermination methods. In Vilna they had needed several days to murder a thousand Jews, in Chelmno half an hour was enough to kill a hundred, and at Treblinka ten thousand were murdered every day!…
