Penhale Camp was established in 1939, to the north of the dunes, as a World War II emergency measure to train anti-aircraft gunners. There still remains evidence of the gun sites, searchlight batteries and defensive positions such as pillboxes and trenches. On 7 June 1940 the camp was bombed by a single German bomber, probably looking for the nearby St Eval airfield; twenty-two British soldiers were killed in the raid, most were subsequently buried in nearby Perranporth.In 1943 the camp was occupied by the United States Army Corps of Engineers as part of the buildup to Operation Overlord, the D-Day landings. The engineers built the fourteen Nissen huts on the Camp; still used today as accommodation for training units. In 1955, three Royal Artillery men drowned while swimming in the sea at Perran Corner. These dangerous waters, with treacherous rip tides, have also claimed the lives of at least two civilians. In April 2010, the camp was closed by the Ministry of Defence and was sold in September that year for £1.5million. However, the area is still governed by Ministry of Defence Byelaws. Today, Penhale Camp and the associated training area are available to all Arms and Services wishing to carry out low level infantry skills training, cadre courses, communications and CPX training. The surrounding area provides opportunities for all recognised adventurous training activities and the newer extreme sports such as power kiting and coasteering. Now established in Penhale Camp is EBO Adventure Centre which provides a diverse range of training activities including Military Resettlement.
