The Military Intelligence Museum Archives hold a wealth of original and facsimile documents from the period, including this notebook from the collection of Major H.F Coleridge, whose hollowed-out bullets, used for carrying messages covertly, appear elsewhere in this topic.
Coleridge’s documents, maps and photographs record a wide variety of information of relevance in a time before electronic, password-protected recording devices. The protection of such written documents was always important as their capture could reveal much to an enemy commander.
Gleaning intelligence from the papers and objects found on captured or killed enemy personnel has always provided a rich stream of data.
Collecting information in this way continues to this day with 2nd Military Intelligence Battalion fulfilling the role of ‘Exploitation’, the analysis of anything and everything found in the battlespace that might assist in developing the intelligence picture.
