In the lead up to the Second World War, Department EH (after its headquarters, Electra House), a war propaganda unit, a section of The Secret Intelligence Service (MI6) called Section D, and a third unit renamed from GS(R) to MI R, were all engaged in related covert operations and research. Operations were co-ordinated and combined to form The Special Operations Executive in 1940. Its main purposes was to carry out espionage, sabotage and reconnaissance in the occupied areas of Europe and to help resistance movements on those and other countries, during the fight against Germany and its allies during the Second World War. It was a Top Secret section of the war effort and the few that knew of its existence referred to it as ‘The Baker Street Irregulars’, ‘Churchill’s Secret Army’, or the ‘Ministry of Ungentlemanly Warfare’. Its activities often took place under more mundane descriptive operational titles such as ‘The Joint Technical Board’ and the ‘Inter Service Research Bureau’. The organisation had 13,000 men and women under its command and helped supply or supported up to a million during the conflict.
