When the Second World War broke out in September 1939 Manouchian, as a foreigner, was evacuated from Paris. He found work in the Rouen area, again as a lathe-operator. After the defeat of June 1940, he returned to Paris to find that his militant activities had become illegal. (French authorities had banned the Communist Party as early as September 1939.) On 22 June 1941, when the invasion of the Soviet Union by the Nazis began, Manouchian was arrested by the occupying Germans in an anti-communist round-up in Paris. Interned in a prison camp at Compiègne, by the efforts of his wife Mélinée Assadourian, he was released after a few weeks without being charged.
