The Battle of Prague, also known as Battle of Štěrboholy, was fought on 6 May 1757, during the Third Silesian War and the broader Seven Years' War, between the Kingdom of Prussia and Habsburg Austria. Although Frederick the Great's army of 64,000 Prussians forced 60,000 Austrians to retreat, he lost 14,300 men and decided he was not strong enough to attack Prague. The battle is mentioned in the famous German ballad Lenore written in 1773 by Gottfried August Bürger.
