Operational Context:
OPREP No. 220 documents the immediate tactical aftermath of the squadron's forward relocation. On the preceding day, 8 March 1943, No. 21 Squadron S.A.A.F. completed a significant move of its flight echelon from Landing Ground (L.G.) Sertan in Tripolitania to L.G. El Assa. Strategically, this move by the Mediterranean Allied Air Forces (MAAF) positioned the unit just 20 miles from the Tunisian frontier, a critical requirement for the Desert Air Force (D.A.F.) as it prepared to support the British Eighth Army's assault on the Mareth Line.
The "NIL" activity recorded for 9 March represents an essential period of operational consolidation at the new forward base. Following the 24 hours and 30 minutes of cumulative flight time required for the move, the technical echelons—specifically the 147 Air Mechanics and 4 Leading Air Mechanics—prioritized the inspection and servicing of the Martin Baltimore fleet. This maintenance was vital to ensure the 86% serviceability rate was maintained despite the primitive conditions of the new desert landing ground.
The transition from Sertan to El Assa significantly reduced the ferry time required for the squadron's primary role: nocturnal "road purification" strikes against Axis Mechanical Transport (M.T.) and fortifications in the Mareth-Zaret-Wadi Zigzaou sector. With the 217 personnel of the "Advance Party" already in place and the air echelon consolidated, the unit was in its final state of readiness to return to high-intensity tactical bombing operations. This archival entry, recorded as Folio 129 in the AIR 27/274 series, represents the unit's final operational stasis immediately prior to the resumption of the Tunisian air offensive.
