To their horror, sometimes the Sonderkommando inductees would discover members of their own family amid the bodies.[5] They had no way to refuse or resign other than by committing suicide.[6] In some places and environments, the Sonderkommandos might be euphemistically connoted as Arbeitsjuden (Jews for work).[7] Other times, Sonderkommandos were called Hilflinge (helpers).[8] At Birkenau the Sonderkommandos reached up to 400 people by 1943, and when Hungarian Jews were deported there in 1944, their number swelled to over 900 persons to accommodate the increased rounds of murder and extermination.[9]
