Mulberry Harbours WW2: Disaster at Dieppe led to D-Day success - IWM > .

Two years before D-Day and Operation Overlord, the Allies mounted a daring rehearsal raid on the French port of Dieppe. The attack ended in disaster, but out of its ashes came one of the greatest unsung inventions of the Second World War, one that would keep the Allies in the fight when they returned to invade Normandy: the Mulberry Harbours. 

Unable to capture a French port, the Allies decided to build their own, float them across the channel and built them on the French coast. Together, the Mulberry Harbours brought in the millions of tonnes of supplies needed to help the Allies break out of Normandy and into Germany itself.

After D-Day, the Allies needed to continually build up reinforcements of men and supplies in Normandy to sustain the invasion's momentum. Previous experience taught the Allies hard but important lessons about the need to secure harbours and ports - harbours to provide protection from bad weather and rough seas, and ports to provide a place to ferry men and cargo. The planners responsible for 'Overlord' proposed creating two artificial harbours - codenamed 'Mulberries' - by sinking outdated ships ('Corncobs') and large concrete structures ('Phoenixes'). Adding floating roadways and piers (codenamed 'Whales') would allow them to use the beachhead as an improvised port.
