The siege of Pirna took place in 1756 as part of the Prussian invasion of Saxony during the Third Silesian War.
Siege of Pirna
The Third Silesian War was a war between Prussia and Austria that lasted from 1756 to 1763 and confirmed Prussia's control of the region of Silesia. The war was fought mainly in Silesia, Bohemia and Upper Saxony and formed one theatre of the Seven Years' War. It was the last of three Silesian Wars fought between Frederick the Great's Prussia and Maria Theresa's Austria in the mid-18th century, all three of which ended in Prussian control of Silesia.
