Series 271 contains the historical operational files for 21 Squadron SAAF. * ANTI-FLAK: Tactical designation for aircraft assigned to suppress enemy anti-aircraft ground batteries during the bomb run. In this mission, aircraft S.566 and G.519 were tasked with this role. * BA-BH (Martin Baltimore): The primary twin-engine tactical medium bomber (Marks IV and V) operated by 21 Squadron SAAF during the Italian Campaign. While not explicitly labeled on this crew list, aircraft callsigns (U, R, C, T, etc.) and numbers (557, 471, 550) denote specific Baltimore airframes. * MC/GP (Medium Capacity / General Purpose): Standard high-explosive ordnance (typically 250lb or 500lb) carried by Baltimore crews for the destruction of logistical infrastructure. * MET (Meteorological Report): Critical weather data required by SAAF crews for navigating trans-Apennine routes between Central Italy and the Po Valley. * OPREP: Operational Report. OPREP No. 970 details the administrative and tactical outcome of Operation 172/21S/M. Operational Context This document catalogs a major 13-aircraft formation strike on March 19, 1945—the second raid of the day—targeting an ammunition dump at coordinates pp C. 186092. By the spring of 1945, 21 Squadron SAAF was a key tactical instrument of Operation Bingo, the strategic aerial campaign designed to achieve total logistical paralysis of German Heeresgruppe C in Northern Italy. The strategic necessity of destroying ammunition reserves follows a pattern of tactical isolation established earlier in the campaign. In November 1943, for instance, 21 Squadron conducted precision strikes on bottlenecks such as location H055630 to maintain pressure on the Bernhardt and Gustav Lines. While those 1943 sorties focused on fracturing immediate front-line logistics, the March 1945 strikes were aimed at systematically neutralizing the enemy's remaining material depth to prevent a coherent fighting withdrawal toward the Alpine passes. The mission was led by senior leadership, with Major Dieu in aircraft U.557. The inclusion of two "ANTI-FLAK" aircraft (S.566 and G.519) indicates an anticipation of concentrated ground defenses protecting the dump. The recorded mission time was 2 hours and 45 minutes for the main formation, with the anti-flak elements logging 2 hours and 30 minutes, likely due to specialized entry/exit profiles. This raid occurred amidst an intense psychological warfare environment, where "Nickel" propaganda sorties informed isolated Axis troops of the ongoing disintegration of the Reich’s domestic defenses. 120 Phase 1: Verification & Extraction Identity Check: 19th MARCH 1945
