There was a diverse array of intelligence streams during the Emergency—including material generated in cordon searches, documents, surrendered or captured insurgents, human intelligence from agents and sources, visual and photographic intelligence. All these streams of intelligence coordination if they were to be used profitably. This chapter traces the difficult process of moving from the infirm post-war organisational structures to creating an intelligence apparatus suitable for fighting an insurgency. The apparatus consisted of numerous different organisations and varied over time. The process of creating an intelligence suitable for counterinsurgency operations was fraught with difficult and false starts, and it was not until just prior to Malayan independence that the apparatus matured and became effective.
