The leadership of the French Communist Party in the period between the occupation of France and the German invasion of Russia on 22 June 1941 was divided between three locations. Secretary-general Maurice Thorez was in Moscow with André Marty. In Paris the clandestine party was directed by Benoît Frachon, aided by Arthur Dallidet. In hiding in Brussels were Jacques Duclos, who became the political leader of the party, and later the leader of the Communist Resistance, Maurice Tréand and Eugen Fried.
