Julius Green

Captain Julius Morris Green (1912–1990) was a British prisoner of war who worked as a spy for MI9 during his time at Colditz Castle. Born in Ireland to a Jewish family, Green moved to Dunfermline at a young age and studied to become a dentist in Edinburgh. He moved to Glasgow following his graduation to work as a dentist, before joining the Territorial Army upon the start of the Second World War.

Green's brigade was captured in June 1940 at St. Valéry-en-Caux, and he spent months travelling between Prisoner-of-war camps providing dental work for fellow prisoners-of-war as well as German troops. Eventually, British intelligence agency MI9 recruited him as a spy to relay information from these camps to assist in rescue efforts and strategic operations. He would write coded letters to his family and friends in Scotland, which would then be analysed by MI9 for secret messages informing them of goings-on within the camps.

After the war, Green married and moved back to Glasgow and worked as a businessman then, later, as a dentist. He wrote a best-selling book about his experiences titled From Colditz In Code (1971). Green's letters were auctioned as part of a mixed lot in June 2015, along with photographs from his camp, and sold for £6,500. Green died in September 1990 at the age of 77.
