Achna setting up a new village (Dasaki Achnas or Achna Forest) which is still in the Dhekelia Sovereign Base Area. The Turkish advance halted when it reached the edge of the Dhekelia Sovereign Base Area to avoid military conflict with the United Kingdom. In the Akrotiri Sovereign Base Area a tented refugee camp was set up at "Happy Valley" (part of the Episkopi Cantonment) to house Turkish Cypriots fleeing from Limassol and the villages surrounding the Area, until in 1975 they were flown out of RAF Akrotiri via Turkey to northern Cyprus. Some Greek Cypriot refugees remain housed on land in the parts of Trachoni and Kolossi villages that fall within the Akrotiri Sovereign Base Area. In 1974, the British government decided that British forces would be entirely withdrawn from Cyprus, because the sprawling bases had become undefendable in the light of increasing troop demands in Northern Ireland, and because of pressure on the defence budget. The U.S. very strongly objected to any British withdrawal that would result in the United States losing access to GCHQ signals intelligence from Cyprus, since it had lost access to its many signals intelligence bases in Turkey due to its political dispute with Turkey following the invasion of Cyprus. The U.S. agreed to contribute to base costs, and the British cancelled the closure plan. U.S. use of the base increased, such as Lockheed U-2 spy flights on Syria, though flights were generally at night "to avoid local curiosity". Politics Current status The territory is composed of two base areas. One is Akrotiri ( ; ), or the Western Sovereign Base Area (WSBA), which includes two main bases at RAF Akrotiri and Episkopi Cantonment, plus all of Akrotiri Village's district (including Limassol Salt Lake) and parts of eleven other village districts. The other area is Dhekelia Cantonment ( ; ), or the Eastern Sovereign Base Area (ESBA), which includes a base at Ayios Nikolaos plus parts of twelve village districts. As of 2022, based units include: RAF Akrotiri and Episkopi Cantonment: No. 903 Expeditionary Air Wing RAF No. 84 Squadron RAF 2nd Battalion, The Yorkshire Regiment Dhekelia Cantonment: 1st Battalion, Princess of Wales’ Royal Regiment Ayios Nikolaos Station, in the ESBA, is an ELINT (electronic intelligence) listening station of the UKUSA Agreement intelligence network. The UKUSA signals intelligence system is sometimes known as "ECHELON". Governance The SBAs were retained in 1960 to keep military bases
