H.Q. R.A.F. M.E

Headquarters, Royal Air Force, Middle East. Operational Context: Sortie Report No. 207 documents the return of No. 21 Squadron S.A.A.F. to high-intensity nocturnal interdiction operations during the transition into the Tunisian Campaign. Strategically, the period of 23/24 February 1943 marks a pivotal shift after the operational pause in Tripolitania. The Mediterranean Allied Air Forces (MAAF) were now directing the Desert Air Force (D.A.F.) to launch focused strikes against the Mareth Line, the formidable Axis defensive system in southern Tunisia where the Afrika Korps had consolidated. The "Task or Duty" identified—individual medium-level bombing of M.T. and fortifications—was part of the "road purification" strategy designed to sever Axis logistics and disrupt the defensive works at Wadi Zigzaou. This specific raid targeted the ROAD MARETH-ZARET, a vital artery for enemy reinforcements. This mission serves as the practical application of the specialized "Baltimore Training" formalized by the squadron on 21 February 1943. The successful navigation from Sertan through multiple waypoints at 8,000 feet and the delivery of a "long stick" of bombs on the Mareth defenses validates the squadron's nocturnal interdiction doctrine. This archival entry represents the unit's decisive reentry into the tactical landscape of the Tunisian theater. 130

S/L

Searchlight. Operational Context: This Part "B" report details the tactical execution and results of Sortie No. 207, flown on the night of 23/24 February 1943. Strategically, the raid represents the resumption of high-intensity nocturnal interdiction by No. 21 Squadron S.A.A.F. against the Mareth Line following the operational pause in Tripolitania. This "road purification" mission was critical to the broader Allied strategy of isolating the Afrika Korps by disrupting reinforcements and logistics between Mareth and Gabes. The focus on the "WADI ZIGZAOU area" highlights the tactical importance of this sector, which was the lynchpin of the Axis defenses in southern Tunisia. The use of 250 lb G.P. bombs with "Rods" indicates a specific intent to clear enemy personnel and soft-skinned vehicles from the roads and fortifications. Despite the reported "Fairly intense" L.A.A. and H.A.A. fire and the use of searchlights, the squadron successfully delivered its "long sticks," claiming direct hits on fortifications and enemy transport. The technical note regarding oxygen—"Used in 3 A/C only. Not available for other A/C"—underscores the logistical constraints faced by the Desert Air Force during this advance. Operating at 9,000 feet without supplemental oxygen increased aircrew fatigue, yet the mission validated the nocturnal doctrine formalized during the February training phase. This archival entry documents the unit's active role in the attrition of Axis defensive strength immediately prior to the primary Allied assault on the Tunisian frontier. 131 Phase 1: Verification & Extraction Identity Check: Night 23/24 February 1943.
