For nine months Guillet launched a series of guerrilla actions against British troops, plundering convoys and shooting up guard posts. At his side was his mistress, Khadija, an Ethiopian Muslim, for he never believed he would ever see Italy or Beatrice again. Two curious British intelligence officers pursued him: Major Max Harrari, later an urbane art dealer who would become Guillet's close friend, and the driven intellectual Captain Sigismund Reich, of the Jewish Brigade, who was eager to get on with the task of killing Germans.
