After serving with the Royal Observer Corps during World War II, his graphic design work was largely replaced by commissioned oil paintings of new vessels. These were often produced from plans so that a painting could be completed before the vessel was launched.

To answer this new threat, Major General Edward Bailey Ashmore, a First World War pilot who had later been in command of an artillery division in Belgium, was appointed to devise improved systems of detection, communication and control. The Metropolitan Observation Service was created, covering the London area, known as the London Air Defence Area, and was soon extended to the coasts of Kent and Essex. This led to the establishment of the Observer Corps in 1925.
