the question of whether SOE should remain a separate body or co-ordinate its operations with those of the British Army in several theatres of war. Hambro felt that any loss of autonomy would cause a number of problems for SOE in the future. At the same time, Hambro was found to have failed to pass on vital information to Selborne. He was dismissed as director, and became head of a raw materials purchasing commission in Washington, D.C., which was involved in the exchange of nuclear information. As part of the subsequent closer ties between the Imperial General Staff and SOE (although SOE had no representation on the Chiefs of Staff Committee), Hambro's replacement as director from September 1943 was Gubbins, who had been promoted to Major-general. Gubbins had wide experience of commando and clandestine operations and had played a major part in MI(R)'s and SOE's early operations. He also put into practice many of the lessons he learned from the IRA during the Irish War of Independence. Organisation Headquarters The organisation of SOE continually evolved and changed during the war. Initially, it consisted of three broad departments: SO1 (formerly Department EH, which dealt with propaganda); SO2 (formerly Section D, operations); and SO3 (formerly MI R, research). SO3 was quickly overloaded with paperwork and was merged into SO2. In August 1941, following quarrels between the Ministry of Economic Warfare and the Ministry of Information over their relative responsibilities, SO1 was removed from SOE and became an independent organisation, the Political Warfare Executive. Thereafter, a single, broad "Operations" department controlled the Sections operating into enemy and sometimes neutral territory, and the selection and training of agents. Sections, usually referred to by code letters or groups of letters, were assigned to a single country. Some enemy-occupied countries had two or more sections assigned to deal with politically disparate resistance movements. (France had no less than six). For security purposes, each section had its own headquarters and training establishments. This strict compartmentalisation was so effective that in mid-1942 five governments in exile jointly suggested that a single sabotage organisation be created, and were startled to learn that SOE had been in existence for two years. Four departments and some smaller groups were controlled by the director of scientific research, Professor Dudley Maurice Newitt, and were concerned with the development or acquisition and production of special equipment. A few other sections were involved with finance,
