CTNana's question prompted me to have a look around for information on Aden and the British involvement. The best site dealing with the Insurgancy is probably http://britains-smallwars.com/Aden/index.html which has masses of information. A good introduction (to better understand all the information in the above site) is: http://en.wikipedia.org/wiki/Aden_Emergency And a detailed analysis of the regional context: From Tribal Rebellions to Revolution: British Counter-Insurgency Operations in Southwest Arabia 1955-67 All fascinating stuff on a region and conflict I knew virually nothing about before. Thank you CTNana for bringing it to my attention.
