H.Q. R.A.F. M.E
Headquarters, Royal Air Force, Middle East. Operational Context: Sortie Report No. 209 documents the third consecutive night of high-intensity nocturnal interdiction conducted by No. 21 Squadron SAAF against the Mareth Line. Strategically, the mission on 25/26 February 1943 was part of the Desert Air Force’s (DAF) "road purification" strategy, designed to systematically sever Axis logistics and reinforcements between the defensive works at Mareth and the supply hub at Gabes. The "Task or Duty" identified—individual medium-level bombing of M.T. and fortifications—directly supported the broader Allied operations by maintaining constant pressure on the Afrika Korps as they consolidated behind the Wadi Zigzaou. The flight path, involving waypoints such as Castel Benito and Homs, illustrates the significant navigational distances required for strikes launched from Tripolitania into the Tunisian theater. The execution of this mission by 10 Martin Baltimores, totaling over 30 operational hours, reflects the successful application of the specialized nocturnal doctrine and "Baltimore Training" formalized by the unit earlier in the month. By operating at 3-minute intervals and bombing from altitudes between 5,000 and 7,000 feet, the squadron minimized the effectiveness of enemy anti-aircraft fire while ensuring continuous coverage of the target area. This archival entry, recorded as Folio 113, documents the unit's finalized tactical alignment immediately prior to the definitive Allied assault on the Tunisian frontier. 138
WADI ZIGZAOU
A steep-sided dry riverbed forming the primary natural anti-tank obstacle and the main defensive barrier of the Axis Mareth system in southern Tunisia.

R.A.F. Form 441 A: The standardized Royal Air Force form used to document individual aircraft sorties and mission narratives.

MARETH -ZARET-ZIGZAOU area: The primary defensive sector of the Mareth Line in southern Tunisia, anchored by the Wadi Zigzaou.

Beacon N (TE 6387): A navigational radio or visual beacon used to orient aircraft toward the target area.

G.P. with 6" rods 43 det.: General Purpose bombs fitted with No. 43 Detonators and 6-inch extended nose fuzes (rods). These "daisy cutters" were designed to trigger the explosion just above ground level to maximize lateral fragmentation against unarmored targets like M.T. and personnel.

long stick: A bombing method where bombs are released in a timed sequence to create a linear impact pattern across a target area.
