embassy staff and others in the Kabul evacuation by air operation. The start of 1931 saw Brooke-Popham promoted to air marshal and then posted as the first RAF officer to serve as Commandant of the Imperial Defence College. Two years later in 1933, he returned to the Air Defence of Great Britain, this time in the senior post of Air Officer Commander-in-Chief. Later that year Brooke-Popham received the honorary appointment of Principal Aide-de-Camp to the King. In 1935 he left the Air Defence of Great Britain to become the Inspector-General of the RAF. This was, however, a short-lived appointment and he was posted later that year. Commander-in-Chief RAF Middle East In late 1935, Brooke-Popham took up the post of Air Officer Commander-in-Chief RAF Middle East with his headquarters in Cairo. His appointment took place not long after the outbreak of the Second Italo-Abyssinian War in October 1935 and his principal aim was to deter the Regia Aeronautica from attacking British territory in north east Africa. In 1937, Brooke-Popham relinquished his command and returned to Great Britain, retiring from the RAF on 6 March. Governor of Kenya Following Italy's occupation of Ethiopia, the British Government wanted a military man to hold the post of Governor of Kenya. Brooke-Popham was appointed Governor and Commander-in-Chief of Kenya in 1937 and his military expertise was useful in helping the colony prepare for a possible war with Italy. Under his direction, a plan was devised which concentrated defensive resources on the strategically important port of Mombasa, which was judged to be the most likely Italian target. Although this left Nairobi and the highlands with only limited defences, the barren regions of northern Kenya meant that the inland settlements were geographically protected from the Italian threat further to the north. Eventually, as the Italian occupation of Ethiopia was characterized by strife and unrest, the threat to Kenya dissipated. Brooke-Popham's governorship was also marked by improved relations with the settlers. His predecessor had sought to dominate the political and economic life of the colony which had aroused repeated opposition from some of the settlers' leaders. However, in courting settler opinion, some historians have criticized Brooke-Popham for failing to deal with those settlers who wanted to limit African and Asian freedoms in Kenya. In 1939 on the outbreak of the Second World War, Brooke-Popham ordered the internment of all Germans in Kenya, directed that all aircraft be commandeered,
