Germany Thought D-Day Would Fail - Then the Allies Brought Their Own Port

German commanders knew the D-Day invasion was coming, but they believed one thing would stop it: logistics. Without a captured deep-water port, they expected the Allied armies in Normandy to run out of fuel, ammunition, and heavy equipment within days. Instead, Operation Overlord unleashed an engineering machine Germany had never prepared for - Mulberry artificial harbors, amphibious DUKW trucks, beach-landing LSTs, DD “swimming” Sherman tanks, specialized engineering vehicles, and an industrial supply system capable of turning open beaches into functioning highways and ports. This documentary explores how Allied technology and overwhelming logistical power shattered German assumptions, transformed the Normandy beachhead, and helped redefine modern warfare.
