 During the war , the German airforce bombed Royal Arthur 52 times , including one incident on 21 August 1940 when an attack led to damage or demolition of 900 small buildings . By the end of the conflict however , the camp 's condition was good enough that it took only 6 weeks for Butlin to repair the wartime damage and reopen the camp to the public on 11 May 1946 . After reopening , some signs of military occupation remained with one observer noting that the blankets supplied to campers retained the insignia of HMS Royal Arthur .
