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 Guards (Poland)
The earliest mentioned document or decree referring to the Royal Guards of Poland dates back to the reign of King John II Casimir. In 1650, the newly established regiment under the command of foreign mercenaries and military commanders was entirely incorporated into the regular, main forces of the Crown over which the monarch or ruler was personally responsible and accountable for. The guards served at the royal courts of Michał Korybut Wiśniowiecki (reigned as Michael I), John III Sobieski, Augustus II the Strong, Augustus III and the last king of Poland Stanisław II Augustus. The first commander-in-chief of the modern regiment was Field Marshal Jakub Henryk Fleming, who held this post between 1717 and 1732.
