Operational Context:
OPREP No. 217 documents a state of continued tactical stasis for No. 21 Squadron S.A.A.F. as of 6 March 1943. Strategically, the squadron was finalizing its reorganization in the Tripolitania sector of Libya following the liberation of Tripoli in late January. During this interval, the Mediterranean Allied Air Forces (MAAF) were utilizing the Desert Air Force (D.A.F.) to transition assets forward to support the imminent Allied offensive against the Afrika Korps entrenched in the Mareth Line defenses in southern Tunisia.
The "NIL" activity for combat and communication flights follows a week characterized by high-intensity nocturnal "road purification" strikes conducted in late February against enemy Mechanical Transport (M.T.) and fortifications in the Mareth-Zaret-Wadi Zigzaou sector. This operational pause was essential for sustaining the squadron's 86% serviceability rate and managing the logistical complexities of moving nearly 40% of the unit’s 579-man strength—the "Advance Party"—forward to new Landing Grounds closer to the Tunisian frontier.
The focus during this period remained on finalized human and mechanical readiness, including the administration of the new "service anywhere" oath (Form DD88BR) and rigorous inspections of personal field equipment. This document, archived as Folio 126 in the AIR 27/274 series, represents the unit's operational status immediately prior to returning to sustained tactical bombing operations to breach the Axis fortifications at the Tunisian frontier.
