[1] The 1943 estimates of how many Jews have died in General Government, are based on data collected while the Holocaust was still in progress, mostly from the preceding year.[1][pp.
[1][3] The Report correctly identified Treblinka, Bełżec, and Sobibór, as extermination camps where prisoners were murdered by means of poison gas, but the fate of the Nazi ghetto deportees was not as clearly defined: About 25,000 Jews were deported from Lublin in sealed railway cars to an unknown destination and all trace of them was lost" [and] "of the 250,000 Jews deported from the Warsaw Ghetto up to September 1, 1942, only two small transports, numbering about 4,000 people, are known to have been sent eastwards in the direction of Brzesc and Malachowicze, allegedly to be employed on work behind the front lines.
[4] The report documented with high accuracy the progress of the Holocaust by bullets in the east as far as localities, but the number of victims was underestimated, with significant percentage of deaths unaccounted for by year's end: In many places the Jews were deported to an unknown destination and killed in neighboring woods.
The same things happened at Zborow, Kolomyja, Sambor, Stryj, Drohobycz, Zbaraz, Przemyslany, Kuty, Sniatyn, Zaleszczyki, Brody, Przemysl, Rawa-Ruska, etc.
[5]According to Michael Fleming, neither the editor, Jacob Apenszlak, nor his collaborators, stated the true scale and manner of the Holocaust in Poland, seeking to elicit empathy from an American public which at that time "was marked by a high level of antisemitism".
