Chanced across the article below on the Association of Jewish Refugees website, it reveals that a Jewish soldier named Hanns Alexander was involved in the capture of former Auschwitz commandant Rudolf Hoess on the night of March 11th/12th 1946 in Gottrupel, near to the German/Danish border.
Alexander had left Germany for Britain in 1937 aged 19, and by the end of WW2 was a member of a British army intelligence unit. This article claims that Hanns Alexander was in charge of Hoess' capture.
Hanns Alexander's presence at the capture of of Hoess isn't mentioned in The Commandant (Maverick, 2008), by British historian Ian Baxter. It's the latest authoritative account of Hoess' capture and interrogation, although Baxter also neglected to mention the role of Vera Atkins, and even Gerald Draper in Hoess' interrogation. Baxter does confirm a "Captain Alexander of the No.1 War Crimes Investigation team" took charge of Hoess on March 15th, and transported him from Heide to Minden ("camp Tomato" is a new term though), where on March 16th, following more physical abuse, Hoess signed a confession written in English. A language, Baxter claims—contradicting Holocaust lore, i.e. Hoess' memoirs, Robert Jan van Pelt, and Prof. Richard Evans—Hoess didn't understand (p.180).
