In the summer of 2014, while Isil besieged Mossul in Iraq, “M” helped devise a secret plan presented to the Americans to rout Isil from northern Syria on the Azaz-Alep line. The plan was detailed street by street, hour by hour, and included the precise itinerary of fighters and their refuelling points. “In every village held by Daesh, knew the number of armed men, where their offices and hideouts were. We had located snipers and mines, we knew where the local emir slept, the colour of his car and even the brand. From a tactical and strategic point of view, we were ready,” he said.
