A WoTR review by Mark Stout onEmpire of Secrets: British Intelligence, the Cold War and the Twilight of Empireby Calder Walton:
It views the process of decolonization during the 1940s, 1950s, and 1960s through the lens of British intelligence operations. Walton’s main message is that “one of the most important ways in which British governments prepared for, and smoothed, the end of colonial rule was with intelligence.”

(Slight snag) The repeated use of, and problems with, pseudo-gangs highlight another important point that Walton brings out: the British intelligence services, unlike the British military, had no mechanism for recording and promulgating lessons learned in the various wars of the period. Instead, MI5 and the Special Branches had to make it all up from scratch in each conflict with the inevitable inefficiencies, failures, and mistakes that happen in the steep part of the learning curve.
