Operational Context:
This "EMERGENCY" signal, issued on the evening of 8 October 1942, documents the final, critical tactical repositioning of No. 21 Squadron's combat aircraft immediately before the commencement of the decisive Allied offensive. While a previous signal on the same day (A.W. 403) had directed the squadron to L.G. 98, this subsequent order makes it "absolutely imperative" that all serviceable aircraft move further forward to L.G. 99 by 07:30 hours on 9 October.
The urgency of this move to L.G. 99 reflects the Mediterranean Allied Air Forces (MAAF) strategy of concentrating light bomber forces at the closest possible proximity to the Alamein front to minimize transit time and maximize the payload and sortie frequency of the squadron's Martin Baltimore aircraft.
Strategically, this positioning was essential for the "shuttle bombing" campaign intended to paralyze Axis logistics and disrupt armored concentrations ahead of the 8th Army's ground assault. The timing—requiring a landing at first light ("0730 tomorrow")—indicates a need for these aircraft to be combat-ready and fueled at the forward strip for operations on the morning of 9 October. This document is archived as Folio 41, providing a primary record of the rapid tactical shifts required to achieve air superiority during the definitive North African campaign.
