Linked to Trinquier's controversial D.P.U. with its system of block-warden informers unpleasantly reminiscent of the Third Reich, and answerable only to Colonel Godard, Léger's G.R.E. assembled a network of top-level Muslim agents, informers who, quite unbeknown to the F.L.N., had turned coat under lesser or greater degrees of coercion at the para interrogating centres. The cornering of Yacef, then of Ali la Pointe, in the final stages of the Battle of Algiers had been ultimately achieved by his bleu double agents.

XREF: Connects to broader literature on colonial reliance on local collaborators and informer networks (e.g., Vichy, anti-insurgency elsewhere). QUESTION: Worth chasing: how 'lesser or greater degrees of coercion' shaped the reliability and loyalty of these bleu agents.
