 The Eichmann Sonderkommando was a task force headed by Adolf Eichmann that arrived in Budapest on 19 March 1944, the same day that Axis forces invaded Hungary. Their task was to take a direct role in the deportation of Hungarian Jews to Auschwitz. The SS-Sonderkommandos enlisted the aide of antisemitic elements from the Hungarian gendarmerie and pro-German administrators from within the Hungarian Interior Ministry. Round-ups began on 16 April, and from 14 May, four trains of 3,000 Jews per day left Hungary and travelled to the camp at Auschwitz II-Birkenau, arriving along a newly built spur line that terminated a few hundred metres from the gas chambers. Between 10 and 25 percent of the people on each train were chosen as forced laborers; the rest were killed within hours of arrival. Under international pressure, the Hungarian government halted deportations on 6 July 1944, by which time over 437,000 of Hungary's 725,000 Jews had died.
