In the course of them it was revealed that Maillot’s arsenal lay buried in a tomb at the Clos Salembier cemetery. Disinterred, the weapons were smuggled by truck to Palestro on the western fringes of Kabylia, where, a few weeks later, they were to help Ouamrane perpetrate the bloodiest reverse to date on the French army itself. … Both he and Maillot have since been enshrined as “Heroes of the Revolution” by the F.L.N., but at the time grave suspicions existed that the maquis rouge might have been betrayed to Boualem’s men by the F.L.N. itself. Such suspicions have never been either allayed or confirmed; while even the circumstances of Yveton’s arrest strike a curious note. Whatever the truth, the F.L.N. undoubtedly viewed the rival maquis rouge with ill-concealed hostility, and this liquidation marked in fact the end of the P.C.A. as a separate entity. … P.C.A. members were, however, never fully trusted by the F.L.N., and were frequently detailed to undertake “suicide missions”. From this background — and the prolonged Soviet reluctance to send the F.L.N. effective arms support — stems the markedly cool relations between Algeria and the U.S.S.R. that were to continue beyond the end of the war itself.
