Siege of Przemyśl
The siege of Przemyśl was the longest siege in Europe during the First World War. The siege was a crushing defeat for the Austro-Hungarian Army against the Russian Army. Przemyśl (German: "Premissel") was a fortress-town and stronghold on the River San in what is now southeastern Poland. The investment of Przemyśl began on 16 September 1914 and was briefly suspended on 11 October, due to an Austro-Hungarian offensive. The siege resumed again on 9 November and the Austro-Hungarian garrison surrendered on 22 March 1915, after holding out for a total of 133 days.
