* APPENDIX "B" CREWS AND MACHINES.

Phase 2: Technical Expansion (The "Transcriber's Notes")
Glossary of Terms
* 21 SQUADRON S.A.A.F.: No. 21 Squadron, South African Air Force. During this phase of 1941, the unit operated within the framework of the Western Desert Air Force, providing medium bombardment and long-range reconnaissance capabilities for the Mediterranean Allied Air Forces (MAAF).
* A/Sgt: Acting Sergeant.
* BA-BH (Martin Baltimore): A twin-engine medium bomber utilized by the squadron beginning in early 1942. At the time of this September 1941 operation, the unit was equipped with the Martin Maryland, as evidenced by the aircraft serial numbers listed (e.g., 1669, 1659) and corresponding squadron history.
* Hq. RAF. ME. S. I. O.: Headquarters, Royal Air Force Middle East, Squadron Intelligence Officer.
* MC/GP (Medium Capacity / General Purpose): Standard high-explosive ordnance classification. For the mission associated with this crew list, these Marylands carried a total load of 18,000 lbs of 250 lb bombs.
* MED. BOMBER WING: A higher command echelon (often identified as 258 Wing in this period) coordinating SAAF and RAF light/medium bomber units.
* METIS: Meteorological Information Services.
* W.O.P. GUNNER: Wireless Operator/Air Gunner.
Operational Context
Target File 272_5 serves as the formal aircrew and airframe manifest for Operational Report No. 2, detailing the 21 Squadron SAAF contingent that carried out the strike against Axis supply dumps North West of Bardia on 24th September 1941. The strategic importance of the mission lay in the degradation of Rommel's logistical tail—specifically motor transport (M.T.) and fuel stores—prior to the large-scale Allied offensive, Operation Crusader.
The manifest identifies 9 Martin Maryland aircraft, organized into three "Sub Flights" of three aircraft each. The lead aircraft, "A" 1669, was piloted by the Officer Commanding, Lt. Col. J.D. Pretorius, demonstrating a leadership-from-the-front doctrine typical of SAAF bomber wings during the desert campaign. The manifest also reveals the multinational character of the Mediterranean air war, listing A/Sgt. Petterson and A/Sgt. Earnshaw alongside South African personnel.
The technical breakdown of the sub-flights correlates with the tactical narrative of the attack: Flight No. 1 (Pretorius, Reid, Long-Innes) dived from 20,000 to 18,000 feet to draw flak and identify the targets, while subsequent flights maintained higher altitudes to saturate the dumps with ordnance. Despite the "fairly accurate" height-finding of Axis coastal batteries near Bardia, these crews achieved a complete return of all 9 airframes with no casualties, underscoring the technical proficiency of the Martin Maryland pilots and the defensive coordination of the air gunners against the ME. 109 interceptors encountered during the egress.

Glossary of Terms
* 21 SQUADRON S.A.A.F.: No. 21 Squadron, South African Air Force. During late 1941, the unit was based in the Western Desert of Egypt, operating under the Air Headquarters Western Desert as part of the nascent Desert Air Force.
* BA-BH (MARTIN BALTIMORE): A twin-engine medium bomber utilized by the squadron beginning in early 1942. At the time of this September 1941 encounter, the squadron was equipped with the Martin Maryland (No. 1645 "J"), the Baltimore's predecessor in SAAF service.
* ME 109: Messerschmitt Bf 109. The primary German single-engine fighter encountered during the North African campaign.
* MC/GP (MEDIUM CAPACITY / GENERAL PURPOSE): Standard Allied high-explosive ordnance. During this mission, the Marylands carried 250 lb bombs for high-level strikes against Axis supply dumps.
* MET: Meteorological section or data. The crew utilized cloud cover—a critical MET factor in this engagement—to break contact with the intercepting fighters.
* PORT QUARTER: The direction approximately 45 degrees to the left of the aircraft's tail.
Operational Context
Target File 272_6 provides a technical combat report from a single aircraft, Martin Maryland 1645 "J", during the high-level bombing raid against Axis supply dumps North West of Bardia on 24th September 1941. The strategic importance of the Bardia region centered on its role as a fortified logistical bottleneck for German and Italian forces near the Egyptian frontier.
The encounter occurred at 18,000 feet while the squadron was without fighter escort. The report, signed by 2/Lt. Long-Innes and A/Sgt. P. Rogers, details a sophisticated coordinated attack by three enemy aircraft—one identified as an ME 109 and two "unidentified" types. The tactical analysis highlights the German use of distraction; while the identified ME 109 maneuvered from the port quarter into a "stern attack" to steady for a shot at 800 yards, the two unidentified aircraft maintained a high-altitude parallel position to fix the SAAF gunners' attention.
Execution constraints for the SAAF crew involved maintaining formation while providing a stable platform for the rear gunners. The gunner's defensive fire was sufficient to deter the ME 109, which broke away without causing damage. The engagement was terminated when the Maryland pilots successfully transitioned into localized cloud cover, a tactic that underscored the reliance on environmental MET conditions for the survival of unescorted medium bombers against high-performance German interceptors during the pre-Crusader phase of the desert war.

Phase 2: Technical Expansion (The "Transcriber's Notes")
Glossary of Terms
* 21 SQUADRON S.A.A.F.: No. 21 Squadron, South African Air Force. In September 1941, the unit operated within the Desert Air Force from bases in Egypt, conducting medium bombardment against Axis logistical centers.
* BA-BH (MARTIN BALTIMORE): A twin-engine medium bomber utilized by the squadron starting in 1942. During this September 1941 encounter, the squadron was equipped with the Martin Maryland, the Baltimore's technical predecessor in SAAF service.
* BARDIA: A strategic coastal port and Axis stronghold in Libya, situated near the Egyptian frontier, which served as a primary target for Allied interdiction.
* MC/GP (MEDIUM CAPACITY / GENERAL PURPOSE): Standard Allied high-explosive ordnance. The Marylands involved in this strike were armed with 250 lb bombs.
* ME. 109: Messerschmitt Bf 109, the primary German single-engine fighter encountered during the North African campaign.
* MET: Meteorological section or data. Weather conditions (4/10 cloud) provided periodic concealment during the return flight from the target area.
* STARBOARD QUARTER: The direction approximately 45 degrees to the right of the aircraft's tail.
Operational Context
Target File 272_7 is a Combat (Bomber) Report detailing a localized aerial engagement during the high-level raid against Axis supply dumps North West of Bardia on 24th September 1941. The strategic importance of this mission centered on the systematic degradation of Axis motor transport (M.T.) and fuel stores ahead of major Allied ground operations.
The report, signed by Lt. W. Mathias, describes the defensive actions of a Martin Maryland flying at 20,000 feet without a fighter escort ("NIL"). While in the "lowest own flight" position, the aircrew identified two ME. 109 fighters positioning for a high-side attack from the starboard quarter, 1,000 feet above the formation. The technical outcome of this encounter was determined by the rapid response of the rear gunner, A/Sgt. V. Oswald, who fired a 20-round burst of defensive fire.
This preemptive fire was sufficient to deter the interceptors, which "peeled off" to the north toward the Mediterranean coast without completing their attack run. This incident illustrates the tactical reliance of unescorted SAAF medium bombers on coordinated formation fire to ward off high-performance German fighters, a critical execution constraint during the high-altitude interdiction missions of the early desert war. The report emphasizes that despite the proximity of enemy fighters, no casualties were sustained by the Maryland aircrew.
