D-Day and Southsea

The area's role in the Normandy invasion

Southsea and Portsmouth played a central role in the preparation and launch of the D-Day invasion of Normandy on 6 June 1944. The city was designated as one of the main embarkation points for the Allied forces, and the build-up to the invasion transformed the area into a vast military staging ground.

In the weeks before D-Day, thousands of troops were assembled on Southsea Common and in camps throughout the surrounding area. Vehicles, tanks, weapons, and supplies filled the streets and open spaces. The seafront was closed to civilians, and the area took on the character of a military zone. Troops embarked from the beaches and the nearby port of Portsmouth, heading across the Channel to the Normandy beaches.

General Eisenhower, Supreme Commander of the Allied Forces, established his forward headquarters at Southwick House, north of Portsmouth, and spent time in the area during the final planning stages. Field Marshal Montgomery was also present. The decision to launch the invasion on 6 June, despite poor weather, was made at Southwick House.

The human scale of the operation was immense. Tens of thousands of soldiers passed through Portsmouth and Southsea in June 1944, many of them spending their last nights in England on the common or in the surrounding streets. The D-Day Story museum on Clarence Esplanade now tells this story, housing the Overlord Embroidery, personal testimonies, vehicles, and interactive displays. The museum was refurbished and reopened in 2018 and is the only museum in the UK dedicated solely to the story of D-Day. Memorials and plaques around the seafront mark specific embarkation points and commemorate those who did not return.
