He did not enjoy the work and in 1886 began to take evening classes at the City and Guilds of London Institute in Finsbury before studying full-time at the Westminster School of Art.
At the first Allied Artist's Association exhibition Bayes met Walter Sickert, who invited him to attend the regular weekly meetings of the Fitzroy Street Group.
[7] During World War I, Bayes continued to teach at the Camberwell School of Arts and Crafts, which was close to the Elephant & Castle tube station on the London Underground.
The scale and composition reflects Bayes's pre-war work as a theatre designer and creates the impression that the viewer is passing through the station, and past the cast of characters on the platform, as if on a train.
[11] In May 1942, however WAAC offered Bayes a short commission to produce a large oil painting on the subject of the air raids that had resulted in damage to parts of Buckingham Palace in 1940 and 1941.
The resulting painting, Battle of Britain: Parachutists from an enemy aircraft brought down in an apparent attempt to bomb Buckingham Palace, led to further war-time commissions.
[12] During the war Bayes was a prolific contributor to the Recording Britain scheme, producing numerous views of interior locations that often focused on leisure activities and people eating and drinking.
