The Portland Mulberry Harbour Phoenix Units are two reinforced concrete caissons, built as part of the artificial Mulberry harbours that were assembled as part of the follow-up to the Normandy landings during World War II. Out of a total of 213 (212 floated) produced units, two units still remain at the Isle of Portland, in Dorset, southern England. They are located at Portland Harbour, close to Queen's Pier. [1] The two units became Grade II Listed in 1993. [2]
When planning the invasion of France the allies knew they needed to supply the troops who were ashore. The only reliable method of landing resources was through a major port. As the German army held all of France's harbours, the solution was the Mulberry harbours. A building program followed, creating two operational harbours within two weeks. [3] The Mulberry harbours were considered a success in their supporting role of Allied troops. [4]
Following the war, ten units were towed to Portland Harbour. [5] Eight of these were later sent to the Netherlands to block breaches in the dykes after the great storm of 31 January 1953. [3] The two units left behind are now used as a wind break, helping ships berth at Queen's Pier. [3] In 2017, six statues were installed on the tops of the units, representing two British Sailors, two American GIs and two Dock workers. [6]
The Mulberry harbours were two temporary portable harbours developed by the British Admiralty and War Office during the Second World War to facilitate the rapid offloading of cargo onto beaches during the Allied invasion of Normandy in June 1944. They were designed in 1942 then built in under a year in great secrecy; within hours of the Allies creating beachheads after D-Day, sections of the two prefabricated harbours were towed across the English Channel from southern England and placed in position off Omaha Beach and Gold Beach, along with old ships to be sunk as breakwaters.
Portland Harbour is beside the Isle of Portland, Dorset, on the south coast of England. Construction of the harbour began in 1849; when completed in 1872, its 520-hectare (1,300-acre) surface area made it the largest human-made harbour in the world, and it remains one of the largest in the world today. It is naturally sheltered by Portland to the south, Chesil Beach to the west and mainland Dorset to the north. It consists of four breakwaters: two southern and two northern. These have a total length of 4.57 km (2.84 mi) and enclose approximately 1,000 ha of water.
Arromanches-les-Bains is a commune in the Calvados department in the Normandy region of north-western France.
Fortuneswell is a village in Underhill on the Isle of Portland, in Dorset, England. It lies on steeply sloping land on the northern edge of the island, known as Underhill, where Chesil Beach connects the island to the mainland. Adjoining Fortuneswell are Chiswell to the west and Castletown to the north. Fortuneswell occupies the steeper land above sea level, whereas Chiswell and Castletown occupy flat land close to sea level, next to Chesil Beach and Portland Harbour respectively. Fortuneswell has a main shopping street, and along with Easton, is the main hub of the island's activities.
Amphibious warfare is a type of offensive military operation that today uses naval ships to project ground and air power onto a hostile or potentially hostile shore at a designated landing beach. Through history the operations were conducted using ship's boats as the primary method of delivering troops to shore. Since the Gallipoli Campaign, specialised watercraft were increasingly designed for landing troops, material and vehicles, including by landing craft and for insertion of commandos, by fast patrol boats, zodiacs and from mini-submersibles. The term amphibious first emerged in the United Kingdom and the United States during the 1930s with introduction of vehicles such as Vickers-Carden-Loyd Light Amphibious Tank or the Landing Vehicle Tracked.
The Phoenix breakwaters were a set of reinforced concrete caissons built as part of the artificial Mulberry harbours that were assembled as part of the preparations for the Normandy landings during World War II. A total of 213 were built, with 212 floated or side-launched. They were constructed by civil engineering contractors around the coast of Britain. They were collected at Dungeness and Selsey, and then towed by tugboats across the English Channel and sunk to form the Mulberry harbour breakwaters replacing the initial "Gooseberry" block ships. Caissons were added in the autumn of 1944 to reinforce the existing structure to cope with the harbour continuing in use longer than planned.
A mole is a massive structure, usually of stone, used as a pier, breakwater, or a causeway separating two bodies of water. A mole may have a wooden structure built on top of it that resembles a wooden pier. The defining feature of a mole, however, is that water cannot freely flow underneath it, unlike a true pier. The oldest known mole is at Wadi al-Jarf, an ancient Egyptian harbor complex on the Red Sea, constructed ca. 2500 BCE.

Operation Overlord was the codename for the Battle of Normandy, the Allied operation that launched the successful liberation of German-occupied Western Europe during World War II. The operation was launched on 6 June 1944 (D-Day) with the Normandy landings. A 1,200-plane airborne assault preceded an amphibious assault involving more than 5,000 vessels. Nearly 160,000 troops crossed the English Channel on 6 June, and more than two million Allied troops were in France by the end of August.
PS Ryde is a paddle steamer that was commissioned and run by Southern Railway as a passenger ferry between mainland England and the Isle of Wight from 1937 to 1969, with an interlude during the Second World War where she served as a minesweeper and then an anti-aircraft ship, seeing action at D-Day. After many years abandoned on moorings at Island Harbour Marina on the River Medina, she was purchased by the PS Ryde Trust in late 2018, with the intention of raising money for her restoration. That project was abandoned in January 2019.

British logistics played a key role in the success of Operation Overlord, the Allied invasion of France in June 1944. The objective of the campaign was to secure a lodgement on the mainland of Europe for further operations. The Allies had to land sufficient forces to overcome the initial opposition and build them up faster than the Germans could respond. Planning for this operation had begun in 1942. The Anglo-Canadian force, the 21st Army Group, consisted of the British Second Army and Canadian First Army. Between them, they had six armoured divisions, ten infantry divisions, two airborne divisions, nine independent armoured brigades and two commando brigades. Logistical units included six supply unit headquarters, 25 Base Supply Depots (BSDs), 83 Detail Issue Depots (DIDs), 25 field bakeries, 14 field butcheries and 18 port detachments. The army group was supported over the beaches and through the Mulberry artificial port specially constructed for the purpose.
There are many Grade II listed buildings in the county of Dorset. This is a list of them.
