During World War II, on 10 May 1940, at the time when Belgium was being invaded, Prince Albert, his elder sister Princess Joséphine-Charlotte and his elder brother Prince Baudouin, left the country for France and later Spain. The Prince and the Princess returned to Belgium on 2 August 1940. They continued their studies until 1944, either at Laeken, or at the Castle of Ciergnon in the Ardennes. In June 1944, at the time of the Allied landings, King Leopold, his wife Princess Lilian and the royal children were deported by the Germans to Hirschstein, Germany, and later to Strobl, Austria, where they were liberated by the American Army on 7 May 1945. Owing to the political situation in Belgium, King Leopold and his family moved to the villa "Le Reposoir" in Pregny, Switzerland, when they left Austria in October 1945 and stayed until July 1950. During that time, Prince Albert would continue his education in a secondary school in Geneva. King Leopold III, accompanied by Prince Baudouin and Prince Albert, returned to Belgium on 22 July 1950.
