Yet, as Servan-Schreiber notes, there was a “symbiosis” gradually growing up between the regulars and the pieds noirs, based on accepting each other’s policy — because there was no other. That policy was, simply, the waging of war à outrance against the rebels. But, in the policy of common interest, each had different objectives that, at the very end, would bring them into tragic conflict; for one, it was to survive in the order of things as before; for the other, chiefly to win a military victory.
