Stanisław Gustaw Jaster, codenamed Hel (pronounced [staˈɲiswaf ˈɡustaf ˈjastɛr] ; born 1 January 1921 in Lviv, died after 12 July 1943 in Warsaw) was a Polish scout, an escapee from the Auschwitz concentration camp, and a soldier of the Home Army. He went missing under unexplained circumstances after 12 July 1943; presumably murdered by fellow conspirators. In 1968, he was accused by Aleksander Kunicki of collaborating with the Gestapo and causing the dismantling of the special unit Osa–Kosa 30, which initiated a long-standing and emotional debate. According to many historians and veterans, Jaster was innocent, and his death was the result of a tragic mistake. This case was one of the most mysterious and controversial episodes in the history of the Polish Underground State. On 25 September 2019, Jaster was posthumously awarded the Knight's Cross of the Order of Polonia Restituta, which can be seen as his symbolic rehabilitation.
