LieutenantJohn Steel "Jock" Lewes (21 December 1913 – 30 December 1941) was a British Army officer prominent during the Second World War. He was the founding principal training officer of the Special Air Service.[1] Its founding commander, David Stirling, said later of Lewes, "Jock could far more genuinely claim to be founder of the SAS than I."[2] Lewes also invented an explosive device for use by the SAS, the eponymousLewes bomb.
A younger brother, David Steel Lewes, was later prominent as a cardiologist in the United Kingdom and was a Royal Air Force medical officer during the war.[8]
At the time of his death, Lewes was engaged to marry Mirren Barford, an Oxford undergraduate. Their love letters were collected and published by Barford's son in 1995.[9]
In 1941, Lewes was in a group of volunteers assembled by David Stirling to form a unit dedicated to raiding missions against the lines of communication of Axis forces in North Africa. For military deception and counterespionage purposes, this platoon-sized group was at first officially known as "L" Detachment, Special Air Service Brigade.[13]
To destroy Axis vehicles, members of the SAS surreptitiously attached small explosive charges. Lewes noticed the respective weaknesses of conventional blast and incendiaries, as well as their failure to destroy vehicles in some cases. He improvised a new, combined charge out of plastic explosive, diesel and thermite. The Lewes bomb was used throughout the Second World War.[5]
In late December 1941, Lewes was involved in an SAS/Long Range Desert Group raid on Axis airfields in Libya. As the raiders returned to Allied lines, their vehicles were repeatedly attacked by Italian and German aircraft. While returning fire on 30 December, near "Marble Arch" (El Gaus; Arco dei Fileni),[14] Lewes was reportedly hit in the thigh by a 20 mm cannon round and died at the scene of the attack.[15] He is commemorated on the Alamein Memorial.[6]
