History of Mulberry Harbour in the UK
In 1940, with the Second World War in full swing, the United Kingdom found itself in a precarious situation, with the possibility of a German invasion looming over the horizon. The UK’s leaders devised a plan to build artificial harbours to support the Allied forces’ landing in Normandy by scaling the heights of the infamous cliffs of Normandy. Winston Churchill visited the site to oversee the construction of this engineering marvel, known as the Mulberry Harbour.
- The construction of the Mulberry Harbour was a feat of remarkable proportions. The Mulberry Harbour was made up of two artificial harbours – Mulberry A and Mulberry B – that were constructed off the coast of Normandy, France, in 1944.
- The Mulberry Harbour consisted of concrete caissons, also called Phoenix units, that were towed across the English Channel and assembled at the build site to form breakwaters. These breakwaters were then anchored to the seabed to secure them.
- The Mulberry Harbours’ most innovative feature was their ‘floating roadways’ made of panels of reinforced concrete, known as ‘Whale’ units. These roadways could withstand severe weather conditions and enabled troops and equipment to move between the shore and the ships.
The Mulberry Harbours played a pivotal role in the success of the D-Day landings and helped reinforce the Allies’ position in France. The Mulberry Harbours remained operational until November 1944, when severe storms wreaked havoc and destroyed much of the infrastructure. The remnants of Mulberry A can still be found in the sea off Arromanches, while some of the Phoenix units have been repurposed to create harbours in England and Wales, such as one in Caernarfon, North Wales.
Importance of Mulberry Harbour during WWII
The Mulberry Harbour was a remarkable engineering project during World War II that played a crucial role in the success of the Allied invasion of Normandy. The Mulberry Harbours were artificial ports constructed on the coast of France, consisting of floating concrete breakwaters, sunken concrete caissons, and floating piers. The aim was to establish temporary harbours where vessels could unload men, machines, and supplies to support the invasion. Here is the importance of Mulberry Harbour during WWII:
- Enabling supply lines: The Mulberry Harbours enabled the Allies to establish a steady stream of supplies from the United Kingdom to troops operating in the European Continent. It ensured that the Allied invasion forces had adequate ammunition, food, fuel, and materials to continue the fight against the German Army.
- Protecting shipping convoys: One of the primary objectives of the Mulberry Harbours was to protect shipping convoys from the furious stormy weather in the English Channel. This feat was accomplished by the use of floating breakwaters, which shielded the harbour from the tidal waves and wind, ensuring smooth operations.
- Reduced dependency on French ports: Before the establishment of the Mulberry Harbours, the Allied forces depended on French ports, which were far from the Normandy beaches and vulnerable to German air raids. The Mulberry Harbours significantly decreased the dependency on French ports, enabling the Allied forces to maintain a strategic foothold in Normandy, even after the operations extended deep into Europe.
Overall, the Mulberry Harbour project was an innovative and ambitious engineering feat that played a crucial role in the Allied victory in World War II. Without the Mulberry Harbours, the Allies would have faced significant logistical challenges, making the success of Operation Overlord, the largest amphibious invasion in history, far less likely.
Here is a table summarizing the Mulberry Harbour project’s scale and resources:
