The Nokmim
In the aftermath of the war, Holocaust survivors led by former members of Jewish resistance groups, banded together. Calling themselves Nokmim (Hebrew for "avengers"), they tracked down and executed former Nazis who took part in the Holocaust. They killed an unknown number of Nazis, and their efforts are believed to have progressed into the 1950s. The Nazis were often kidnapped and killed by hanging or strangulation, others were killed by hit-and-run attacks, and a former high-ranking Gestapo officer died when kerosene was injected into his bloodstream while he was in hospital awaiting an operation. It is possible that some of the most successful Nokmim were veterans of the Jewish Brigade, who had access to military intelligence, transport, and the right to freely travel across Europe.
Nokmim also traveled to places such as Latin America, Canada, and Spain. to track down and kill Nazis who had settled there. In one instance, they are believed to have confronted Aleksander Laak, responsible for killing 8,500 Jews at Jägala concentration camp, at his suburban Winnipeg home, and after telling him that they intended to kill him, allowed him to commit suicide.
In 1946, the Nokmim carried out a mass poisoning attack against former SS members imprisoned at Stalag 13, lacing their bread rations with arsenic at the bakery which supplied it. Some 1,900 inmates fell ill, and it is thought that several hundred to a thousand died.
