Westphalia, Hesse and Lower Saxony Electoral Saxony Brandenburg Silesia East Prussia Pomerania Iberian Peninsula Naval Operations The siege of Glatz took place in 1760 during the Third Silesian War (part of the Seven Years' War) when an Austrian force led by General von Laudon laid siege to and successfully stormed the fortress of Glatz (Czech: Kladsko, Polish: Kłodzko) from its Prussian garrison.

On 6 June Laudon surrounded Glatz, but he had to wait until heavy artillery was brought from Olmütz (Olomouc) in neighbouring Moravia.

The arrival of his heavy artillery had allowed the siege to properly begin on 20 July and a trench had been dug.

Once the guns had weakened the defences Laudon was able to organise volunteers to storm the city, opening the gates and allowing the remainder of the Austrian army to enter.

[2] Following a series of extensive manoeuvres and several heavy battles during 1760 Glatz ultimately remained the only territory captured by the Austrian and their allies leaving the situation almost unchanged since a year before.
