It has been generally asserted and believed that the ball was given by the duchess in the grand hall of the stately Hôtel de Ville in the Grande Place, and when in Brussels I heard the assertion repeated by many people, though denied by others. One old citizen, who remembered the battle well, affirmed it to have been at the Hôtel de Ville, which he saw brilliantly lighted up for the occasion, and passed among the crowd of equipages that filled the Grande Place, when setting down and taking up the ladies who graced the assembly with their presence. Another equally old and trustworthy inhabitant declared that to his personal knowledge the ball was given in the “Palais d’Aes,” a large building that adjoins the palace of the King of the Belgians, and is now used as a barrack; while a third affirmed it to have been held in the handsome hotel, adjoining the Chamber of Deputies, which was formerly occupied by Sir Charles Bagot, the British Ambassador to Brussels and the Hague in 1830. Thinking there could be no better authority than one who was present on the occasion, one, moreover, who was so nearly allied to the giver of the entertainment, I asked Lord William to decide the point. He replied at once that all these assertions were unfounded. His father, the Duke, took a large house in a back street, called the “Rue de la Blanchisserie” (street of the laundry), abutting on the boulevard, opposite the present Botanic Garden, and that the ball took place in the not extraordinarily spacious drawing-room of that mansion. He said, moreover, that the lines— Within the window’d niche of that high hall Sat Brunswick’s fated chieftain, conveyed an idea of magnitude which the so-called “high hall” did not in reality possess. Archbishop Whately here said: “If we may be permitted without breach of good manners to speak of Waterloo in the presence of Prince Napoleon, I may remark that the correction of the very minor error just made by Lord William, though exceedingly interesting is not of great importance. Though contradicted again and again, the report still circulates, and is still believed, that the Duke of Wellington was surprised on the eve of the battle of Waterloo by the rapid march of the emperor, and was thus taken at a disadvantage.” “I never believed the report,” said the Prince, “though I have my own views about the battle. I visited Waterloo in the winter of 1832, with what feelings you may imagine.”
