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.
Royal Horse Guards
Wellington was the first Blues Gold Stick and was colonel of The Blues until 1827. This put the regiment on a similar parity with Life Guards in terms of access to the king. The Duke, however, did not believe in bucking the chain of command, and declined to exercise extraordinary influence outside the fact that The Blues had become part of the Household Cavalry on 29 January 1820. Wellington did approve of the appointment of Lord Combermere to the Life Guards, but when the Duke of York died in 1827, the Iron Duke was finally made commander-in-chief. When Wellington became colonel of the Grenadier Guards (previously 1st Foot Guards) he was made to give up the Gold Stick. His successor was Ernest, Duke of Cumberland. The royal Duke believed the Gold Sticks-in-waiting should have absolute authority over their regiments. But the old Duke of Northumberland had resigned over this very issue and the new King William IV had the last word. He ruled that in all operational matters beyond ceremonial duties, the Household Cavalry would fall into the Commander-in-chief's care and command. Cumberland angrily resigned in a huff.
