Vice-Admiral John Hughes-Hallett CB DSO (1 December 1901 – 5 April 1972) was a British naval commander and politician. He was the Naval Commander during the Dieppe Raid of 1942. Early life and career Hughes-Hallett was born in December 1901, to a distinguished armed services family. His father was Colonel Wyndham Hughes-Hallett, his mother Clementina Mary Loch (25 Mar 1869 – 8 Dec 1948). They were relatively old at 56 and 31 years old, respectively, at the time of his birth. Educated at Bedford School, Hughes-Hallett had a distinguished career in the Royal Navy, beginning as a Midshipman on HMS Lion, May 1918. He was promoted to staff rank and during the Second World War served in a variety of roles. During the Norwegian campaign of 1940 he saw active service on HMS Devonshire and was mentioned in despatches. Later naval career In 1940 to 1941 Hughes-Hallett played a key role in cross-Channel raids. He assisted in planning raids under Mountbatten and was the Naval Commander during the misconceived Dieppe Raid of 1942. Although the raid itself was not successful and cost many lives, it did lead to new strategies for cross-Channel operations. The actual proposer of the idea of the Mulberry Harbour is disputed, but it is believed by some to have been Hughes-Hallett. At a meeting following the Dieppe raid, he declared that if a port could not be captured, then one should be taken across the Channel. Although this was met with derision at the time, the concept of Mulberry Harbours began to take shape when Hughes-Hallett moved to be Naval Chief of Staff to the Operation Overlord planners. Hughes-Hallett became Commodore commanding the Channel Assault Force and Naval Chief of Staff (X) from 1942 to 1943. Of the five Assault Forces, Hughes-Hallett's Force "J" started its training with a decided advantage over the other four; its nucleus having been formed as far back as October 1942, with headquarters at Cowes. On 1 May 1943, Commodore Hughes-Hallett succeeded Rear Admiral Philip Vian as the head of the Naval Branch at Supreme Allied Command. He served as Captain of HMS Jamaica from December 1943. After the war, he was in command of HMS Vernon, (1946-8). Vernon in Portsmouth was the navy's Torpedo training centre and he had to cope with the problems arising from the recent creation of the Electrical branch. Until this a ship's electrics had been
