Operational Context
This document serves as the formal title page for the Permanent Historical Record of the Mediterranean Allied Air Forces (MAAF) operations during the North African and Italian campaigns. Specifically, the file series AIR 27/275 contains the Operations Record Book Appendices for No. 21 Squadron, South African Air Force (SAAF), among others.
The strategic importance of these records lies in their meticulous documentation of tactical operations during the pursuit phase of the Tunisian campaign in early 1943. While squadrons like No. 21 SAAF—operating Martin Baltimore Mk. III aircraft—carried out strikes against Axis Motor Transport (MT) and Landing Grounds (LGs) at Sfax and Gabes, the Headquarters echelons collated these appendices to provide a comprehensive tactical landscape of the Desert Air Force's (DAF) effectiveness. These documents allow historians to connect individual raids, such as the suppression of Axis anti-tank screens at the Tebaga Gap, to the broader Allied objective of collapsing the German and Italian bridgehead in North Africa. The preservation of these "Appendices" by the Air Historical Branch ensures the verbatim survival of intelligence summaries and sortie reports that defined the MAAF's air-land doctrine.
