Dennis Wheatley described Bevan as “a rather frail-looking man of medium build with sleepy pale blue eyes and thin fair hair which turned gray from the strain of the remarkable work he accomplished”.

Upon his arrival the LCS was struggling to maintain its authority against the armed forces establishment. Bevan and his deputy, Dennis Wheatley, used their social connections (and a broad charter from high command) to enable the department to put plans into operation. In 1943 Bevan helped establish Ops (B) (a deception department within COSSAC) and plan Operation Cockade. Intended to tie up German forces in western Europe, the operation was not a success. However, building on the lessons learned from Cockade (and from Dudley Clarke in the Mediterranean) Bevan created Operation Bodyguard, which historians agree contributed to the success of the Operation Overlord landings in 1944.
