LONDON--Gen. Charles De Gaulle, leader of the Fighting French, announced by radio tonight that the moment has come for French patriots to "revolt against their leaders of treason" and he urged those in the homeland to begin by resisting attempts to force them into German labor service.

He spoke less than two hours after Pierre Laval had appealed by radio from Vichy for skilled French workers to cowerate with the Germans so that "France won't be the victim of a German victory."
