When he was 14, Delon left school. He then worked for at his stepfather's butcher shop for some time. He joined the French Navy three years later. In 1953 and 54 he served as a "fusilier marin" in the First Indochina War. Delon has said that out of his four years of military service he spent eleven months in prison for being "undisciplined", meaning that his bad behaviour ended up getting him jailed. In 1956, he returned to France after being dishonourably discharged from the navy. He did not have any money, and lived on whatever money he could find.
