David Bomberg's experiences of mechanized slaughter and the death of his brother in the trenches - as well as those of his friend Isaac Rosenberg and his supporter T. E. Hulme - permanently destroyed his faith in the aesthetics of the machine age. This can be seen most clearly in his commission for the Canadian War Memorials Fund, Sappers at Work (1918–1919): his first version of the painting was dismissed as a "futurist abortion" and was replaced by a second far more representational version.
