ANNEX B. Security Lessons from Operation "Torch" Extracts from Lt.Col. S.S. Hill-Dillon's (G.S.O.1.I (b), AI Report dated 6 March, 1943. It is essential that a security staff officer with considerable experience should be attached to the planning staff to keep a constant watch on the security situation. To assist him in carrying out necessary measures, security personnel must be available. This latter work can be carried out most efficiently by Field Security Section. Some fifty serious cases of violation of security were investigated during the planning stage of "Torch", some so serious that Courts Martial were necessary and the publication of their findings had considerable effect.
