Phase 2: Technical Expansion (Transcriber's Notes)
Glossary of Terms:
* APPENDIX "A": A standardized supplemental sheet to the Operations Record Book (ORB) used to list detailed personnel and equipment data for a specific sortie.
* OPERATION NO. 80: The specific mission reference number assigned by the squadron for the raid conducted on January 8, 1942.
* Machine No.: The individual aircraft identification, consisting of a squadron code letter (e.g., "L", "A", "E") and the military serial number (e.g., 1668, 1669, 336).
* Pilot/Observer/W.Op. Gunner/Gunner: The standard four-man crew complement for a Martin Maryland light bomber; "W.Op. Gunner" denotes the Wireless Operator/Gunner.
* Sub Flight: A tactical subdivision of the squadron formation, typically consisting of three aircraft flying in a "V" or vic formation for mutual defense and bombing concentration.
Operational Context:
This document serves as the personnel and airframe annex for Operation No. 80, conducted on 8 January 1942. Historically, this operation targeted Marble Arch Landing Ground and Ras-el-Ghrabigh. During this period, the Eighth Army was maintaining pressure on the retreating Axis forces near the El Agheila position. The use of eight aircraft—organized into two full sub-flights and one partial sub-flight—indicates a significant commitment of 21 Squadron's operational strength for this mission.
The crew lists show a mixture of experienced officers and non-commissioned officers, including Major Thackwray leading the 1st Sub Flight in aircraft 1668 ("L"). The presence of serial numbers such as 1668, 1669, and 1652 identifies these machines as Martin Marylands, which were the primary tactical strike aircraft for 21 Squadron SAAF during the Cyrenaican campaign before their eventual transition to the Martin Baltimore. The meticulous recording of these crews was essential for casualty tracking and assessing squadron operational readiness during the high-intensity interdiction missions characteristic of the Western Desert air war.

* S.I.O.: Senior Intelligence Officer, located at both H.Q. R.A.F. M.E. and A.H.Q. W.D.
* H.Q. R.A.F. M.E.: Headquarters, Royal Air Force Middle East.
* A.H.Q. W.D.: Air Headquarters, Western Desert.
* OPS.: Operations section at Air Headquarters, Western Desert.
* 3 (S.A.) Wing: No. 3 (South African) Wing, the administrative and tactical formation overseeing 21 Squadron.
Operational Context:
This Postagram, recorded under Originator's Reference No. OP. 81, documents a tactical strike on 9 January 1942, a pivotal moment following the conclusion of Operation Crusader. As the Axis forces under General Rommel retreated toward the defensive bottleneck at El Agheila, the primary objective of the Desert Air Force was the interdiction of retreating Motor Transport (M.T.) and the disruption of logistical consolidation.
The location "East of El-Agheila 3775" represents a critical concentration point for the Panzergruppe Afrika as they transitioned from Cyrenaica into the more defensible positions of Tripolitania. The deployment of seven Marylands dropping 14,000 lbs of ordnance from 9,000 feet indicates a concentrated effort to exploit the vulnerability of the ± 250 vehicles identified in the target area. The report of "1 direct hit vehicle" and all bombs landing within the target area suggests successful implementation of high-level bombing tactics despite hazy conditions. The observation that only a "few M.T." were heading West along the road at that specific time provides significant intelligence regarding the pace of the German withdrawal and the effectiveness of Allied pressure on their lines of communication.
