In 1914, during World War I, at the age of 17, Edwin William Conquest Flavell enlisted in the East Surrey Regiment and was commissioned as a second lieutenant five months later.

In 1916 he transferred to the newly formed Machine Gun Corps, and in 1917 he was believed to be the youngest major serving in the Flanders area at the age of 20.

[1] During the interwar period Flavell remained on the active list of the East Surrey Regiment, but became involved in the shipping industry with a business partner from the United States.

When the Second World War broke out in September 1939, Flavell was recalled to the British Army and subsequently given command of the 2/7th Middlesex Regiment.

[1] His adjutant was Captain John D. Frost, who would later become famous for commanding the battalion during the Battle of Arnhem; both men qualified as parachutists in October 1941.

[1] In the spring of 1942 Gale was promoted to deputy director of Staff Duties at the War Office,[18] and he passed command of the brigade over to Flavell.

[19] Flavell, promoted to brigadier,[20] transferred command of 2nd Parachute Battalion to Major Gofton-Salmond,[21] and in the beginning of November the brigade was sent to North Africa as part of Operation Torch.

[26][28] The brigade ended its operations in North Africa in mid-April 1943, and Flavell left for England in June to take up a new command.

[1] On the night of 5 June the division conducted Operation Tonga, the British airborne portion of the Allied invasion of Normandy.

He was then appointed as Deputy Chief of Staff HQ in First Allied Airborne Army, and subsequently made an Officer of the American Legion of Merit.

In the 1945 general election, Flavell stood as the Conservative candidate for Hendon North in Middlesex, but was defeated by a slim margin.
