The Siege of Weissenstein took place between May 31 and September 30, 1602, during the Polish–Swedish War (1600–11). Two weeks after the capture of Fellin, Grand Crown Hetman Jan Zamoyski led the Polish-Lithuanian army of 2,000 troops to besiege Weissenstein (now known as Paide in Estonia). Weissenstein, a major transportation hub in Estonia, was a site of strategic importance to both Poland and Sweden.
