Operational Context:
OPREP No. 223 documents a continued state of tactical consolidation for No. 21 Squadron S.A.A.F. following its rapid forward relocation across Tripolitania. Strategically, the squadron had recently completed two major moves within 48 hours, shifting from Landing Ground (L.G.) Sertan to El Assa on 8 March, and then to L.G. Zuara on 10 March. These movements were mandated by the Mediterranean Allied Air Forces (MAAF) to keep the Desert Air Force (D.A.F.) in close proximity to the British Eighth Army as it finalized preparations for the assault on the Mareth Line in southern Tunisia.
The "Nil" combat activity for 12 March reflects an essential period for the technical echelon—comprising 147 Air Mechanics and 4 Leading Air Mechanics—to stabilize operations and perform maintenance at the new forward base. Sustaining the unit's 86% serviceability rate was critical given the primitive conditions of forward desert airfields and the high-intensity interdiction raids conducted earlier in the month.
The 1 hour of Communication flight recorded represents a brief logistical or ferry mission, likely supporting the final coordination of the "Advance Party" infrastructure now established at Zuara. With 29 fully trained aircrews available and the unit now positioned just miles from the Tunisian frontier, the squadron was in a high state of readiness to resume "road purification" nocturnal strikes against Axis Mechanical Transport (M.T.) and fortifications. This archival entry, recorded as Folio 132 in the AIR 27/274 series, represents the unit's final operational stasis immediately prior to returning to sustained tactical bombing operations.
