At the end of January 1958 Hani Mohamed and Safy-le-Pur made a rendezvous at the zone's headquarters outside Bordj-Menaiel, on the western approaches of Kabylia. With them came Léger, disguised in a cachabia, Surcouf and several other members of the G.R.E. The F.L.N. leaders were completely deceived; by the following dawn the zone's entire general staff was aboard helicopters bound for French prisons; a large bomb factory and arms depot had been captured, as well as quantities of incriminating documents that would lead to the mounting of further deadly bleu operations.

XREF: Relates to the broader 'bleu de chauffe' counterinsurgency operations discussed in the surrounding text (FALN/FLN betrayal operations).
