Mulberry Harbour construction site and troop embarkation point, Stokes Bay

This site was used for the construction of Phoenix caissons, which were part of the Mulberry Harbours (artificial harbours) – as well as for the embarkation of large numbers of troops.

The use of Mulberry Harbours was vital to the success of D-Day as they allowed thousands of tonnes of vehicles and goods to be unloaded onto the Normandy beaches each day. Tugboats towed construction components for these floating harbours across the Channel before being assembled off the Normandy coast. Two harbours were built in total: ‘Mulberry A’ was constructed at Omaha Beach and ‘Mulberry B’ at Gold. Each harbour required a vast 140,000 tonnes of concrete.

A key part of the Mulberry Harbours was the outer breakwater. To create the breakwater, old ships and concrete Phoenix caissons were sunk in lines to create the breakwater. The Phoenixes were large concrete structures, with hollow chambers inside. They could be floated in order to move them, but when water was let into the internal chambers they would sink onto the sea bottom. These caissons were towed to the harbour site and then sunk in a controlled manner to eventually provide 6 miles of breakwater protection.

Fourteen of these vast caissons were constructed at Stokes Bay, Gosport. Between November 1943 and April 1944, 1,600 men worked day and night under extreme pressure and in dangerous conditions. On one occasion, as a caisson was being launched, it toppled killing three workers.

The beach at Stokes Bay also functioned as an embarkation point, with concrete slabs laid directly onto the beach, creating embarkation ‘hards’ that allowed for lorries and armored vehicles to embark onto landing craft without getting bogged down on the beach.
