HM Fort Roughs

HM Fort Roughs was one of several World War II installations, that were designed by Guy Maunsell and known collectively as His Majesty's Forts or as Maunsell Sea Forts, and its purpose was to guard the port of Harwich, Essex. The naval fort is situated on Rough Sands, a sandbar located approximately six miles from the coast of Suffolk and eight miles from the coast of Essex.

It later became a self-proclaimed, unrecognised state called the Principality of Sealand.

History of HM Fort Roughs

1943: Dry dock construction

Fort Roughs was constructed in 1942. It comprised a floating pontoon base with a superstructure of two hollow towers joined by a deck upon which other structures could be added. The pontoon was reinforced concrete measuring 168 by 88 feet. The fort was topped by a gun deck, an upper deck and a central tower unit which housed the radar equipment. The twin towers were divided into seven floors that provided dining and sleeping accommodation and storage areas for generators and munitions. There was a steel framework at one end supporting a landing jetty and crane which was used to hoist supplies aboard. Electricity needs were met by several generators.

On February 11 1943 the fort was towed by three tugs to a location on Rough Sands where its base was intentionally flooded so that it sank to a resting place on the sandbar. At that time Rough Sands were situated in international waters. The superstructure of the vessel above the waterline remained visible from the coastline of England. HMS Roughs was in operation within 30 minutes of being launched. The crew had been aboard during the fitting out in harbour and were well acquainted with the fort's equipment. Approximately 100 men were assigned to the barge before deployment on Rough Sands, and the facility was occupied by 150-300 Royal Navy personnel throughout WWII. At the conclusion of hostilities all original personnel were evacuated from HMS Fort Rough. The armament consisted of 3.75 inch AA guns and Bofors 40 mm guns - the standard medium and light anti-aircraft weaponry of the British and Commonwealth forces.

1956: Removal of full-time HMG personnel from Rough Tower

British government official entities used Rough Tower for a variety of purposes until 1956 when all full-time personnel were finally removed. Rough Tower remained identified by name on buoys placed in position by the Ministry of Defence which are maintained under an arrangement with Trinity House. Their purpose is to warn vessels of this obstacle, especially in time of fog because busy shipping lanes criss-crossed the area with vessels going to and from the container Port of Felixstowe, Suffolk, and the Port of Harwich, Essex. UK Ordnance Survey now identify the former sea barge fort as Rough Tower on their charts.

1966: Occupation

In 1966 Paddy Roy Bates who operated Radio Essex and Ronan O'Rahilly who operated Radio Caroline landed on Fort Roughs and occupied it. However, after disagreements, Roy Bates seized the tower as his own. O'Rahilly attempted to storm the fort in 1967, but Roy Bates defended the fort with guns and petrol bombs and continued to occupy the fort. The British Royal Marines went on alert and the British Authorities ordered Roy Bates to surrender. In his refusal, Roy Bates founded the Principality of Sealand on 2 September 1967.
