Royal Observer Corps
In 1929 the control of the Observer Corps passed from the county police forces to the Air Ministry, although Chief Constables retained responsibility for personnel and recruitment matters. 1 March 1929 saw the establishment of the new "Headquarters of the Observer Corps" at Hillingdon House, RAF Uxbridge in the west of London, and Air Commodore Edward A D Masterman CB CMG CBE AFC RAF (Rtd) was appointed as the first commandant of the Observer Corps. "Air Cdre" Masterman held this appointment until his retirement on 1 March 1936, and was succeeded by Air Commodore Alfred Warrington-Morris CG CMG OBE AFC RAF (Rtd), who would lead the Observer Corps through the critical period during the Second World War which saw the RAF emerge bruised but victorious following the Battle of Britain of 1940.
Archduke Charles, Duke of Teschen
When Karl Mack von Leiberich became chief of staff of the army under Prince Josias of Saxe-Coburg-Saalfeld in the Netherlands, he issued the "Instruktionspunkte fur die gesamte Herren Generals", the last of 19 points setting out the roles of staff officers, dealing with offensive and defensive operations, while helping the Commander-in-chief. In 1796, Archduke Charles augmented these with his own "Observationspunkte", writing of the Chief of Staff: “he is duty bound to consider all possibilities related to operations and not view himself as merely carrying out those instructions”. On 20 March 1801, Feldmarschalleutnant Duka became the world's first peacetime "Generalquartiermeister" at the head of the staff and the wartime role of the Chief of Staff was now focused on planning and operations to assist the Commander. Archduke Charles produced a new Dienstvorschrift on 1 September 1805, which divided the staff into three: 1) Political Correspondence; 2) the Operations Directorate, dealing with planning and intelligence; 3) the Service Directorate, dealing with administration, supply and military justice. The Archduke set out the position of a modern Chief of Staff: “The Chief of Staff stands at the side of the Commander-in-Chief and is completely at his disposal. His sphere of work connects him with no specific unit”. “The Commander-in-Chief decides what should happen and how; his chief assistant works out these decisions, so that each subordinate understands his allotted task”. With the creation of the Korps in 1809, each had a staff, whose chief was responsible for directing operations and executing the overall headquarters plan.
