APPENDIX "B" CREWS AND MACHINES.

Phase 2: Technical Expansion (The "Transcriber's Notes")
Glossary of Terms
* H. Q. RAF. ME. S. I. O.: Headquarters, Royal Air Force Middle East, Squadron Intelligence Officer.
* MACHINE NO. (Serial Numbers): The aircraft designated (e.g., 1664, 1669, 1667) are Martin Maryland medium bombers. These American-built twin-engine bombers were the primary equipment for No. 21 Squadron SAAF during the late 1941 desert campaign, preceding the introduction of the Martin Baltimore.
* OP. GUNNER: Operator Gunner. This crew position combined the responsibilities of a wireless telegraphy operator (radio) and a defensive air gunner.
* SUB FLIGHT: A tactical subdivision of the squadron formation; for this mission, nine Marylands were organized into three mutual-support sub-flights of three aircraft each.
Operational Context
Target File 272_75 provides the comprehensive aircrew and airframe manifest for Operational Report No. 9, detailing the 21 Squadron SAAF contingent that conducted a strike on 5 October 1941. The target was a strategic Axis logistical node at grid 494407, situated just north of the Tobruk-Bardia road. This location functioned as a critical "dispersed dump" for fuel and motor transport recently offloaded from maritime vessels at Bardia.
This sortie was the third consecutive attack on this specific bottleneck, part of a concentrated effort by the Mediterranean Allied Air Forces (MAAF) to neutralize German and Italian mobile reserves ahead of the planned winter offensive, Operation Crusader. The presence of senior leadership in this manifest, including Maj. Fowler and Maj. Stewart leading the 1st and 2nd Sub Flights, underscores the mission's tactical priority.
Execution Constraints
The mission was executed as a high-level horizontal bombing run from staggered altitudes of 12,000 ft, 12,500 ft, and 13,000 ft. A significant tactical constraint noted in the main report was the observed take-off of nine Axis fighters from Bir - El - Baheira as the formation operated in the sector.
While no anti-aircraft (A/A) fire was encountered during the target run, the aircrews listed in this manifest delivered 18,000 lbs of ordnance, with the second and third flights achieving a 70% concentration in the main dump area. The document, signed by Intelligence Officer Lt. L. Saunders, records a successful recovery and return of all nine airframes to base after a cumulative flight time of 23 hours. These crews provided essential visual and photographic reconnaissance on secondary targets, including active motor transport movement and Axis landing ground status at Sidi Aziz and Capuzzo North.
