The siege of Dresden took place in July 1760 during the Third Silesian War (part of the Seven Years' War) when a Prussian force led by Frederick the Great unsuccessfully besieged the city of Dresden in Saxony.
Frederick had previously occupied Dresden in 1756 during his Invasion of Saxony, which had triggered the outbreak of war. In 1759 it had been taken back by Austria-led forces. Frederick now targeted it in an attempt to reassert control over Saxony where he had expansionist territorial ambitions. The Prussian army reached the outskirts of Dresden on 13 July followed closely by a corps of Austrian troops under Count von Lacy. Frederick's forces crossed the River Elbe and overran the suburbs of the city bringing up heavy guns to target inside the city walls.
