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.
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.
[3] On 12 June 1940, Green and his brigade were captured at St. Valery-en-Caux,[5] after Major General Victor Fortune and French troops surrendered to Erwin Rommel.
He travelled from camp to camp—staying at Blechhammer, Lamsdorf, Sandbostel, Westertimke, and Heyderbreck—providing dental work for both German troops and fellow prisoners of war, and eventually ended up at Colditz Castle.
Letters he sent to his family in Dunfermline between 1941 and 1944 would contain lines that were, to native speakers, effectively nonsense; however, these were coded messages to be decrypted by Intelligence staff in London.
[9][13] A collection of forty letters sent to and from Colditz, as well as photographs and imagery of Green and other PoWs, were auctioned by Bonhams in Knightsbridge, London, on 18 June 2014, with an estimated sale price of between £4,000 and £6,000.
