On 7 September Gingembre — his briefcase stuffed with incriminating documents — flew from Paris to Algiers. With him on the plane was Colonel Debrosse himself, the head of the Algiers gendarmerie, whose men had suffered so appallingly at the hands of “ultra” sharpshooters on that “bloody Sunday” of 24 January 1960. Debrosse settled an old score by arresting Gingembre, who, says Susini, “immediately began to talk at the top of his voice”. On the resultant information, police in France swooped to arrest a number of senior French army officers.
