This document is an official reprint from a commemorative series that provides an interim report on the Allied airborne assault in Holland during World War II. It describes how U.S. and British airborne forces, including paratroopers and glider-borne troops, were organized to seize vital bridges over the Maas, Waal, and Neder Rijn rivers, thereby aiming to flank the German Siegfried Line defenses. The report details the meticulous planning behind the operation, including the selection of staging airfields, routing of troop carrier aircraft, precise timing schedules, altitude specifications for safe drops and landings, and the placement of navigational aids such as Eureka beacons and marker boats. It also covers challenges encountered from heavy enemy flak, counterattacks by German fighters, and adverse weather conditions that affected resupply and reinforcement missions. Furthermore, the document highlights the role of fighter escorts, air-sea rescue services, and the significant logistical efforts that, despite some losses, resulted in a successful concentration of forces and provided critical support to the ground advance in the campaign.
