Signals intelligence in India

In May 1945, as France celebrated the end of the Second World War in Europe, its foremost overseas dependency, Algeria, erupted into rebellion. Revisiting the roles and responses of the colonial security forces to what came to be known as the Sétif uprising, this article suggests two things. One is that the intensity of repressive violence pursued becomes more explicable once we consider the part played by political intelligence gathering in the operation of French colonial government in Algeria. The other is that the decision to use the political intelligence amassed before, during, and after the rebellion to coerce the Algerian population at the rebellion's epicentre signified a fundamental shift in the nature of the French colonial state in Algeria. Intelligence-led security policing, much of it later adopted by police agencies in metropolitan France at the height of the Algerian War, became more repressive, less selective, and highly violent.
