At the decrease of WW II, Mary Churchill, daughter of the British prime minister, was a devotee of a British all-women anti-aircraft battery 481 that was stationed at Huldenberg for three months. She was entertained by the then burgomaster of Huldenberg, Count Thierry de Limburg Stirum and his wife Marie, née Princess of Croÿ. She noted that she found the local people very kind and long-suffering and stated (“somewhat priggishly” she admitted) “…the flouting by everything of and sundry of whatever regulations existed here, and the wide-spread use of the flourishing ‘black market’. This had been regarded as something like a ‘patriotic duty’ during the occupation, but it was still going upon now – apparently unrestrained.”
