Before D-Day, German engineers were confident the Allied invasion would fail. Without capturing a major port, they believed, no army could survive on the beaches of Normandy. When Allied intelligence reports mentioned “floating harbors,” Nazi planners dismissed the idea as fantasy.
Then, just days after June 6, 1944, the impossible appeared. Massive concrete caissons, floating roadways, and anchored piers rose from the English Channel. The Mulberry Harbors began unloading thousands of tanks, trucks, and soldiers every single day, even under artillery fire and stormy seas. German commanders watched in disbelief as the invasion not only survived—but became unstoppable.
In this 12-minute documentary, discover how one of the boldest engineering feats in history shattered German expectations and ensured the success of D-Day.
