How fewer than 800 defenders stopped an Ottoman army of over 100,000 soldiers
In 1532, Sultan Suleiman the Magnificent marched toward Vienna with a massive force. Standing in his way was Kőszeg, a minor border fort defended by fewer than 50 soldiers and 700 villagers. Against all odds, this tiny garrison held out for nearly four weeks, effectively saving the Austrian capital from siege.
The Siege of Kőszeg occurred during the 'Little War,' a series of conflicts between the Habsburg monarchy and the Ottoman Empire. Following his failed 1529 attempt to capture Vienna, Suleiman launched a fifth imperial campaign in 1532. While his stated goal was to confront Holy Roman Emperor Charles V, Suleiman diverted his army of over 120,000 troops toward the small, strategically insignificant town of Kőszeg.
Commanded by Croatian diplomat Nikola Jurišić, the defenders faced nineteen full-scale assaults and constant bombardment. Despite lacking artillery and having only a few guns, the garrison utilized countermines to neutralize Ottoman tunneling efforts. The Ottomans, led by Suleiman and Pargalı Ibrahim Pasha, expected a quick victory but were stalled for nearly four weeks. This delay proved fatal to the Sultan's broader ambitions; by the time he considered moving on to Vienna, the August rains had arrived and a formidable imperial army had assembled in the capital.
The exact conclusion of the siege remains debated. Some accounts suggest Jurišić rejected surrender terms, while others claim a nominal surrender occurred, allowing a token Ottoman force to raise their flag. Regardless, the outcome was a strategic victory for the defenders. Suleiman withdrew toward home, avoiding a direct confrontation with the reinforced imperial forces. Although the 1533 Treaty of Constantinople later formalized territorial claims between Ferdinand I and John Zápolya, the defense of Kőszeg remains a remarkable instance where a seemingly inconsequential obstacle halted the expansion of a superpower.
