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 it. The British Royal Marines went on alert and the British authorities ordered Roy Bates to surrender. He and his son were arrested and charged, but the court threw out the case as it did not have jurisdiction over international affairs: Roughs Tower lay beyond the territorial waters of Britain. Bates took this as "de facto" recognition of his country and seven years later issued a constitution, flag, and national anthem, among other things, for the Principality of Sealand (founded on 2 September 1967).
