|Sir Reginald Henderson|
|Commands held||HMS Erin|
|Battles/wars||World War I|
|Awards||Knight Grand Cross of the Order of the Bath|
Henderson was confirmed as a sub-lieutenant in the Royal Navy in 1902, and posted to HMS Syren in April that year. He took part in the Naval Mission to Greece in 1913. He served in World War I as commanding officer of the battleship HMS Erin in 1914 and took part in the Battle of Jutland in 1916.
In 1917, as a commander involved in anti-submarine warfare, he quietly opposed the Admiralty's official position that the volume of merchant shipping was too great to be protected by warships. Henderson demonstrated that the vast majority of the 2,500 ships completing voyages each week were in fact coastal voyages, and only between 120 and 140 ocean-going. Hankey's biographer Stephen Roskill suggested that Henderson's contribution to the introduction of convoys (in particular to Hankey's memorandum of February 1917) was not acknowledged on paper at the time in order to avoid imperilling the younger officer's career.
Henderson later promoted the Fleet Air Arm and the construction of aircraft carriers. He was given command of the aircraft carrier HMS Furious in 1926 and became Naval Aide-de-Camp to King George V in 1928. He was appointed Rear Admiral commanding aircraft carriers in 1931 and Third Sea Lord and Controller of the Navy in 1934 before his death in 1939.
In 1911 he married Islay Campbell.
