Following the outbreak of the Second World War, the British jockey Charlie Elliott returned to England, giving up his job as the first jockey for the Marcel Boussac the dominant owner-breeder of his time. Semblat replaced Elliott and rode for Boussac with considerable success and soon took over the role of trainer. In 1944 Semblat sustained serious injuries in a fall which forced him to retire from riding.
