 A major success was the conversion of Jacques Soustelle, who went to Algeria as governor general in January 1955 determined to restore peace.Soustelle, a one-time leftist and by 1955 an ardent Gaullist, began an ambitious reform program (the Soustelle Plan) aimed at improving economic conditions among the Muslim population.The FLN adopted tactics similar to those of nationalist groups in Asia, and the French did not realize the seriousness of the challenge they faced until 1955, when the FLN moved into urbanized areas.
