Prince Charles, Count of Flanders, Prince of Belgium was the second son of Albert I, King of the Belgians and Duchess Elisabeth in Bavaria. Born in Brussels, he served in lieu of his older brother King Leopold III from 1944 until 1950 as Prince Regent until Leopold could return to Belgium and resume his monarchial duties. Shortly after however, Leopold abdicated in favour of his heir apparent, his son Baudouin.
Charles was known as General Du Boc during World War II in order to hide his identity for security reasons. He had an association with RAF Hullavington where many top officers from allied nations were based or transported to and from.
