section of the book and independently published her own conclusions, reiterating the points she had made five years before. These can be summarised as follows: KL Warschau started its operation in October 1942, just after Himmler's first order (see Creation section); The Warsaw concentration camp was, according to Trzcińska, an extensive complex consisting of five subcamps: the main camp, which purportedly had previously served as a POW camp for the Polish Army soldiers detained after September 1939, was located in a small forest in the neighbourhood of Koło called ; two were located in the former ghetto (one on Gęsia street, which is the generally recognised location, and another on street); and two were located near the Warszawa Zachodnia station. These are said to have extended over an area of around , containing 119 barracks capable of housing 41,000 inmates. KL Warschau, as Trzcińska purported, operated as an extermination camp for Poles. Around 200,000 people, mostly ethnic Poles, were said to have been exterminated by gassing and mass shootings. A road tunnel under the railway line, which is today part of (then part of ), was allegedly converted into a gas chamber, which she claimed played a central role in that extermination. The Polish People's Republic authorities were loath to study the history of the Warsaw concentration camp or commemorate its victims, as they were afraid of disclosing the information about the functioning of Soviet NKVD and Polish Communist MBP administrations in KL Warschau. Refutation The contentions, in addition to not being confirmed by Bogusław Kopka, have also been refuted by the IPN in a later analysis by . The findings were also cast in doubt by other historians, including Władysław Bartoszewski, Tomasz Szarota, Andreas Mix and Jan Żaryn. In particular, they say that: no credible evidence exists for the assertion that KL Warschau had more camps than the one at Gęsia street. There is no testimony whatsoever about the existence of the camp at Bonifraterska street; as for three other camps which supposedly existed, available testimony is scarce, is contradictory and contains few details. There is also no evidence for a POW camp in Koło neighbourhood that had allegedly existed before KL Warschau, or in general of any spatially separated camps; there is no credible evidence for the hypothesis that KL Warschau was an extermination camp, or that it featured a giant gas chamber under the railway tracks.
