to Auschwitz, where most were murdered. Einsatzgruppe H reported that some Jews were able to escape because of insufficient personnel, but that both Germans and Slovaks generally supported the roundups and helped track down evaders. After the defeat of the uprising, the German forces also hunted the Jews hiding in the mountains. Although most victims were arrested during the first two months of occupation, the hunt for the Jews continued until 30 March 1945, when a Jewish prisoner was taken to Sereď just three days before the camp was liberated. Some Jews had been arrested in Bratislava by 20 September. The largest roundup was carried out in the city during the night of 28/29 September by Einsatzkommando 29, aided by 600 HS and POHG collaborators and a Luftwaffe unit that guarded the streets: around 1,600 Jews were arrested and taken to Sereď. Some 300 Jews with foreign citizenship were temporarily housed in a castle in Marianka. Brunner raided the castle on 11 October; all but three of the prisoners were taken to Sereď and deported to Auschwitz on 17 October. In mid-October, an office was established at the former Jewish Center to hunt down Jews in hiding, which tortured captured Jews into revealing the names and addresses of other Jews. The one to two thousand Jews left in Bratislava were ordered to turn themselves in on 20 November or face imprisonment, but few did so. Half of the Jews arrested after 19 November were in Bratislava, most in hiding with false papers. Henri Dunand of the Red Cross provided funding for a clandestine group led by Arnold Lazar, which provided money, food, and clothing to Jews in hiding in Bratislava. Deportation Sereď concentration camp was the primary facility for interning Jews before their deportation. Although there were no transports until the end of September, the Jews experienced harsh treatment (including rape and murder) and severe overcrowding as the population swelled to 3,000 – more than twice the intended capacity. Brunner took over the camp's administration from the Slovak government at the end of September. About 11,700 people were deported on eleven transports; the first five (from 30 September to 17 October) went to Auschwitz, where most of the victims were gassed. The final transport to Auschwitz, on 2 November, arrived after the gas chambers were shut down. Later transports left for Sachsenhausen, Bergen-Belsen, Ravensbrück, and Theresienstadt. Two small transports left
