The D.P.U. block-warden system produced intelligence but destroyed Muslim loyalists

Evidence

But in the long run it was to place the “loyal” Muslim block-wardens in a thoroughly invidious position, often resulting either in their assassination or in the end of their loyalty to France. — Horne, Alistair, A Savage War of Peace- Algeria 1954-1962, 588 (#corroborates, via linked claim)

Massu’s system of quadrillage and the rifling of the police dossiers was augmented by the work of a new body called the Dispositif de Protection Urbaine (D.P.U.). Created by order of Lacoste and placed under the control of that Indo-China expert on subversive warfare, Colonel Roger Trinquier, in its operation the D.P.U. carried with it sinister undertones that also could not help but recall French experiences under the Third Reich. It divided the city up into sectors, sub-sectors, blocks and buildings, each bearing a number or letter (even today the hieroglyphs can still be found painted on the fronts of houses in the Casbah). To each block was nominated a responsable, generally a Muslim ancien combattant considered trustworthy, and to this block-warden fell the duty of reporting all suspicious activities occurring within his territory. — Horne, Alistair, A Savage War of Peace- Algeria 1954-1962, 588 (#expands, via linked claim)
