In the uprising of 1830 led by revolutionary army cadets, the target was Grand Duke Constantine, Poland's Governor-General. Count Moritz Hauke was on his way to the Grand Duke who managed to escape, but Hauke was shot to death by the cadets on the street of Warsaw before the eyes of his wife, Sophie Lafontaine (daughter of Franz Leopold Lafontaine), and his three younger children. He was riding on a horse beside the carriage of his wife and having met a group of rebels who shouted: "Be our leader, General!" Hauke reprimanded them and told them to go back to their quarters, whereupon they opened fire and killed him. His wife died shortly afterward, and their younger children were made wards of the Tsar, while three elder sons joined the uprising and one of them, Maurice Leopold, fell during the battle of Ostrołęka in 1831 only 27 years old. After his victory over the Poles, the Tsar raised in 1841 an enormous obelisk in Warsaw, which was dedicated to the memory of Hauke and five other Polish generals who "preserved their fidelity to their Monarch". Detested by the inhabitants of the Polish capital, the obelisk was pulled down in 1917.
