The deportations of Jews from Slovakia started on 25 March 1942, but halted on 20 October 1942 after a group of Jewish citizens, led by Gisi Fleischmann and Rabbi Michael Ber Weissmandl, built a coalition of concerned officials from the Vatican and the government, and, through a mix of bribery and negotiation, was able to stop the process. By then, however, some 58,000 Jews had already been deported, mostly to Auschwitz. Slovak government officials filed complaints against Germany, when it became clear that many of the previously deported Slovak Jews had been gassed in mass executions.
