Operational Context:
OPREP No. 215 documents the continued tactical consolidation of No. 21 Squadron S.A.A.F. in early March 1943. Strategically, the squadron remained based at forward Landing Grounds in the Tripolitania sector of Libya following the capture of Tripoli in late January. During this period, the Mediterranean Allied Air Forces (MAAF) were utilizing the Desert Air Force (D.A.F.) to build up logistical and technical strength for the definitive drive against the Afrika Korps entrenched in the Mareth Line in southern Tunisia.
The "NIL" combat entry follows a significant period of high-intensity nocturnal "road purification" strikes against enemy Mechanical Transport (M.T.) and fortifications conducted in late February. The 5 hours and 30 minutes of Communication flight by a single Baltimore represents a substantial ferry mission, likely involving the transport of technical specialists or critical spare parts between forward airfields and rear maintenance hubs.
This administrative stasis provided an essential interval for the technical echelon to perform airframe maintenance and for the squadron to finalize the training of its 29 aircrews for the upcoming nocturnal interdiction phase of the Tunisian Campaign. This document, archived as Folio 122 in the AIR 27/274 series, represents the unit's operational status immediately prior to returning to sustained tactical bombing operations against Axis supply lines.
