In May 1809, Major Franz Hackher zu Hart received orders to defend the Schlossberg against Napoleon's troops. Together with 17 officers and 896 soldiers he held the fortress against the mighty foe. The French totalled 3000 men and launched eight unsuccessful assaults. Only after an armistice had been arranged did Hackher withdraw with his men. A monument was erected in honour this heroic defender in 1909 - the "Hackher Lion".
