His younger brother Admiral Sir Reginald Portal ( 1894 – 1983 ) joined the Royal Navy and also had a distinguished career . The Portals had Huguenot origins , having arrived in England in the 17th century . Charles Portal , or " Peter " as he was nicknamed , was educated at Winchester College and Christ Church , Oxford . Portal had intended to become a barrister but he did not finish his degree and he left undergraduate life to enlist as a private soldier in 1914 . First World War . At the beginning of the First World War , Portal joined the British Army and served as a dispatch rider in the motorcycle section of the Royal Engineers on the Western Front . Portal was made a corporal very soon after joining the Army and he was commissioned as a second lieutenant only weeks later . Around the same time , Portal was commended in Sir John French ' s first despatch of September 1914 . In December 1914 , Portal was given command of all riders in the 1st Corps Headquarters Signals Company . In July 1915 , with the need for dispatch riders reducing , Portal transferred to the Royal Flying Corps ( RFC ) . He served first as an observer and then , from November 1915 , as a flying officer . He graduated as a pilot in April 1916 , and joined No . 60 Squadron flying Morane biplanes on the Western Front . He became a flight commander with No . 3 Squadron flying BE2c aircraft on the Western Front on 16 July 1916 . Portal was promoted to temporary major in June 1917 and given command of No . 16 Squadron flying RE8 aircraft on the Western Front at the same time . He was promoted to temporary lieutenant - colonel on 17 June 1918 and given command of No . 24 ( Training ) Wing at RAF Grantham in August 1918 . Portal was awarded the Military Cross in January 1917 , the Distinguished Service Order on 18 July 1917 and a Bar to his DSO on 18 July 1918 . Inter - war years . In August 1919 Portal was appointed to a permanent commission in the Royal Air Force in the rank of major ( shortly afterwards redesignated as a squadron leader ) . He became a chief flying instructor at the Royal Air Force College Cranwell in November 1919 and then attended RAF Staff College in 1922 , before joining the air staff conducting flying operations in the home sector in April 1923 . Promoted to wing commander on 1 July 1925 , he attended the senior officers ' war course at the Royal Naval College , Greenwich , in 1926 before taking over No . 7 Squadron flying Vickers Virginia bombers from RAF Worthy Down in March 1927 and concentrated on improving bombing accuracy . He attended the Imperial Defence College in 1929 and then became Deputy Director of Plans in the Directorate of Operations & Intelligence at the Air Ministry in December 1930 .

Portal was promoted to air vice marshal on 1 July 1937 before being appointed Director of Organization at the Air Ministry on 1 September 1937 . Second World War . Appointed a Companion of the Order of the Bath in the 1939 New Year Honours , Portal became Air Member for Personnel on the Air Council on 1 February 1939 . He was promoted to the acting rank of air marshal on 3 September 1939 , appointed commander - in - chief of Bomber Command in April 1940 and promoted to the substantive rank of air marshal on 1 July 1940 . Portal advocated strategic area bombing against German industrial areas , the same sort of targets that the Luftwaffe was already targeting in the United Kingdom . He was advanced to Knight Commander of the Order of the Bath in the 1940 Birthday Honours . On 25 October 1940 , Portal was appointed as Chief of the Air Staff with the temporary rank of air chief marshal ( made permanent in April 1942 ) . He continued in this capacity for the remainder of the war . The first issue he had to resolve was an attempt by the Royal Navy to take over RAF Coastal Command as well as an attempt by the British Army to establish their own Army Air Arm . Portal successfully persuaded both the Army and the Navy that the RAF could adequately look after their needs . The second issue Portal had to resolve was the need for a renewed strategic bombing offensive . In August 1941 he received a report on the relative inefficiency of RAF daytime raids and proposals for area bombing by night : to implement the proposals he determined that a new leader was required and replaced the chief of bomber command , Air Chief Marshal Richard Peirse , with Arthur Harris . He was advanced to Knight Grand Cross of the Order of the Bath in the 1942 Birthday Honours . Portal accompanied Churchill to all the great conferences and made a good impression on Americans . In January 1943 , at the Casablanca Conference , the Combined Chiefs of Staff selected him to coordinate the bomber forces of both the United States and Britain in a combined bomber offensive over Germany . The forces were transferred to U . S . General Dwight D . Eisenhower for the duration of Operation " Overlord " ; but when their control reverted to the Combined Chiefs , Portal still advocated area bombing of German cities instead of specific targets . He was promoted to Marshal of the Royal Air Force on 1 January 1944 . In early 1944 , Portal ' s view of strategic bombing changed ; he felt that bombers could also play a more auxiliary role in the allied offensive . ( Much of what is known about Portal ' s thinking is based on memoranda he wrote . ) He argued for the new approach on the basis of the huge increase in the size of the bomber force , which would carry out not just precision bombing but also indiscriminate area bombing by night of all German cities with populations exceeding 100 , 000 . Portal thought that the resulting damage to the German war effort and civilian morale would lead to victory within six months . A second memorandum in 1945 made a similar argument . In March 1945 , Churchill gave the final order to stop Portal ' s strategy of area bombing , after the firestorm of Dresden a few weeks earlier . Churchill subsequently distanced himself from the bombing writing that " the destruction of Dresden remains a serious query against the conduct of Allied Bombing " . Post - war . In 1945 , after the war ' s end , Portal retired from the RAF and on 12 October 1945 he was raised to the peerage as Baron Portal of Hungerford , of Hungerford in the County of Berkshire , with remainder , failing male issue of his own , to his daughters and their male heirs . On 8 February 1946 he was further honoured when he was made Viscount Portal of Hungerford , of Hungerford in the County of Berkshire , with normal remainder to his heirs male . He was made a member of the Order of Merit on 1 January 1946 . He was also awarded the American Distinguished Service Medal on 15 March 1946 and appointed a Knight Grand Cross of the Dutch Order of Orange - Nassau on 18 November 1947 . He was also appointed a Knight Grand Cross of the Belgium Order of the Crown with Palm and awarded the Belgian Croix de Guerre , 1940 , with Palm on 27 August 1948 . From 1946 to 1951 , Portal was Controller of Production ( Atomic Energy ) at the Ministry of Supply . He attended the funeral of King George VI in February 1952 and the coronation of Queen Elizabeth II in June 1953 . Portal was elected Chairman of British Aluminium and in 1958 / 1959 he fought in the City of London ' s " Aluminium War " against a hostile takeover bid by Sir Ivan Stedeford , Chairman and Chief Executive of Tube Investments . T . I . along with its ally Reynolds Metals of the US , won the takeover battle , and in the process , rewrote the way the City of London conducted its business in relation to shareholders and investors . Stedeford replaced Portal as Chairman of British Aluminium . In 1960 Portal was elected chairman of the British Aircraft Corporation . Portal died from cancer at his home at West Ashling near near Chichester on 22 April 1971 . Family . In July 1919 , Portal married Joan Margaret Welby ; they had a son ( who died at birth ) and two daughters .
