Today, we commemorate the 75th anniversary of ‘D-Day’, the largest seaborne invasion in history. Codenamed Operation Neptune, this Allied invasion of Normandy commenced on 6 June 1944 as part of Operation Overlord, during World War II. The operation began the liberation of German-occupied France (and later Europe) from Nazi control, and laid the foundations of the Allied victory on the Western Front.We will take a look at Southampton’s role in the operations through the papers and photographs collected by American Colonel James O’Donald Mays [MS 379/3 A4024], whose Army Port unit was assigned to Southampton to direct American military activities for the preparation for D-Day and its follow-up. He later worked as a diplomat, journalist and author.
During the ensuing summer days and nights, Southampton witnessed a sight unparalleled in all its long momentous history. The military traffic, chiefly U.S.A., roared on in an unending torrent.
Almost every road and street carried its weight of vehicles, two and sometimes three a breast; trucks swept by loaded with soldiers, huge petrol tanks, jeeps, searchlights, DUKWs, great guns, tank-transporters and tanks without number, the giant Shermans roaring and grinding past, shaking the houses as they went.
Local historian Elsie M.Sandell writing for a 40th anniversary commemorative magazine produced by the Evening Echo, June 1984
Southampton was all but taken over by the military in the lead up to D-Day. Southampton Common accommodated large numbers of Allied troops and the foundations of their huts are still visible after long spells of dry weather. The Bargate in the shopping centre was a Military Police post.
Southampton was chosen as the chief supply and troop movement centre for the American army, known as the 14th Major Port of the US Army Transportation Corps. It was the centre of marine operations as the first shipment point for American men and supplies from the UK to the Continent. Southampton was essential in discharging of cargo before D-Day, loading of landing craft and other assault vessels for the European invasion and build up, and shipping of United states-bound troops under the re-deployment programme.The 14th Port staff arrived in the United Kingdom on 16 July 1943 and three days later began operations at London, Southampton and Plymouth. Up to 1 February 1944, Port Headquarters were in London. When Allied strategists selected Southampton as the chief loading point for troops and war materials for the invasion, headquarters were moved to Southampton Civic Centre; offices were later relocated to Houndwell Park.
The port of Southampton was selected because of its strategic location. The “double tide” effected by the position of the Isle of Wight at the bottom of The Solent meant the port was perfectly suited for mass loading and sailing of vessels. It also benefited from a huge anchorage space off Cowes as well as deep water docking facilities and spacious loading sheds.Some impressive statistics for the period include that 8,300 ships passed through the harbour. Approximately 2,500,000 men were transported to and from the Continent and the United States and 3,000,000 tons of goods were carried to European ports and beaches.
The operation naturally had a huge impact on the city and its civilian population. Three Southampton schools were used as billets for United States Army troops. Swaythling Infant (Mayfield), Taunton’s and Ascupart Road.This huge flow of men and vehicles required co-ordination. Military police escorts were required and checkpoints established and a checking system was instigated to help prevent congestion in Southampton’s streets. Routes were planned to interfere as little as possible with civilian transport.
The Army Transportation Corps Harbour Craft Companies were attached to the 14th Port and it was their job to operate the hundreds of small tug-boats, floating cranes and other harbour craft assigned to the Port. One of the key vessels was the LST – Landing Ship Tank – a “lifeline” to supply Europe. It was capable of carrying 50 to 75 vehicles; 2,539 LSTs were loaded at Southampton.
D-Day marked a key victory in the Second World War: it prevented Hitler launching his new V-weapons against British cities in a last-minute effort to save Germany. For more on Southampton’s role in this momentous event, see the Library’s Cope Collection for additional resources.
