At the start of the Second World War, Worsley joined the Royal Navy. His drawings of life at sea caught the attention of the War Artists’ Advisory Committee, and he was appointed as a full-time war artist.
In 1943 Worsley was captured by the Germans and detained at Marlag ‘O’, a prisoner-of-war camp. He continued to paint at the camp, documenting prison life using materials provided by the Red Cross. These parcels contained food and other supplies, reminding the men that they had not been forgotten. The tin cans were re-used for a variety of purposes, in Worsley’s case to safely carry his pictures to freedom in April 1945.
His skills as an artist were employed to forge identity papers. He also made a life-sized mannequin called Albert during an ingenious escape attempt, which in 1953 was made into a film, Albert R.N.
