During World War II (1939–45) when the Germans occupied France Pujo stayed with Maurras in Lyon. After Léon Daudet died in 1942 Pujo was made co-director of the daily "Action Française". He was imprisoned by the Gestapo for three weeks in June 1944. In January 1945 Pujo and Maurras were tried for collaboration and Pujo was sentenced to five years in prison. He was released in October 1947. He then became political director of "Aspects de la France" until his death on 6 September 1955. Pujo has been called "a kind of exalted flunky and right-hand man for Maurras."
