Siege of Wolmar

The Siege of Wolmar occurred during the Polish–Swedish War (1600–1611), between October 18 and December 18, 1601. Polish forces, numbering around 15,000, with 50 pieces of artillery, led by the Grand Crown Hetman Jan Zamoyski besieged the city (present day Valmiera) defended by about 1,000 infantry under Jacob De la Gardie and Carl Carlsson Gyllenhielm. Other notable commanders on the Polish side included the Field Crown Hetman Stanisław Żółkiewski and the field marshal Jürgen von Farensbach (Jerzy Farensbach). The king of Poland, Sigismund III Vasa, was initially present at the siege, but left for Wilno on December 5th. At first the Swedish artillery managed to hold back the Poles who did not intend to storm Wolmar without proper siege cannons. However, on December 8th such pieces arrived and an intense bombardment of Wolmar was executed which continued for ten days. Finally on December 18th, when the cannons had breached two entrances in the walls, the Polish troops managed to storm the defenses and entered the city. The Swedish garrison withdrew to the town's castle where they defended themselves and held back the Poles for a while. Later, when the situation became particularly disadvantageous, they asked for conditions of surrender. Subsequently, after capitulation, the Swedish officers were taken prisoner by the Poles while the rank and file soldiers were allowed to leave after swearing an oath that they would not continue to fight against the Polish-Lithuanian Commonwealth. The captured Swedish generals Pontus De la Gardie and Carl Carlsson Gyllenhielm were treated very well until they were transferred to the king. Sigismund decided to lock them in the castle of Rawa. Conditions there became very tough. De la Gardie was exchanged and returned to the Swedish army in 1605. Gyllenhielm was held captive until 1613.
