Coxon was contacted by the Committee in March 1940. After a meeting, Coxon suggested a picture of "the Potteries with the Skelton Iron and Steel works", or to go to Palestine as an official artist, having served in the cavalry there during the First World War. However, the Committee preferred the suggestion of army subjects at home, and Coxon was commissioned to paint two Horse Guards subjects for £50. By June, he had still not started, having had problems getting the necessary permits.
The first picture Coxon submitted, in September 1942, was not liked by the Committee, but two further works, LD 283 and 683, were accepted in November, although two others were declined at that time.
No further official commissions were made, but Coxon submitted works, as did his wife, Eva Ginesi, and some of Coxon's were accepted: LD 1830 in February 1942 for 30 guineas (25-25); IWM:ART LD 2161 in June 1942 for 20 guineas (31); LD 2466 in September 1942 for 10 guineas, Coxon having negotiated the price up from 7 guineas (34ff); and IWM:ART LD 3266 in January 1944 for 25 guineas (46).
