Operational Context This document catalogs an 11-aircraft formation strike on March 16, 1945, targeting the Gorizia Marshalling Yards. Gorizia, located near the Yugoslav border, was a critical junction on the rail network supporting German forces in North-East Italy and those retreating from the Balkans. Its interdiction was a core objective of Operation Bingo, the strategic aerial campaign intended to achieve total logistical paralysis of German Heeresgruppe C. The strategic methodology employed at Gorizia reflects the tactical evolution of 21 Squadron since its earlier operations against the Bernhardt and Gustav Lines. During November 1943, the squadron conducted high-precision strikes on specific bottlenecks, such as location H055630, to fracture German defensive coherence and prevent reserves from reaching the front. By March 1945, the tactical focus shifted from breaching defensive lines to the systematic destruction of the enemy's logistical depth in the rear. The mission was led by the Squadron Commander, Lt. Col. D. Ord, in aircraft 513 Hv. Notably, aircraft 475 P, piloted by Lt. Isted, was designated as the "Wind Finding A/C," reflecting the requirement for high-altitude bombing precision in the Alpine approaches. The handwritten marginalia, such as "HARLE," "du Plessis," and "CERONIO" replacing struck-through names, indicate the administrative tracking of last-minute crew substitutions. This raid took place as Allied air forces maintained crushing pressure on German transport, while "Nickel" propaganda sorties informed isolated Axis troops of the ongoing disintegration of the Reich’s domestic defenses. 117 Phase 1: Verification & Extraction Identity Check: 18th MARCH, 1945
