Mörner and Stenbock were ordered to bring their 4,000 troops from Vilnius to Warsaw. The march across central Poland was obstructed by skirmishes against Wiśniowiecki's troops and wide rivers. On several occasions Stenbock used his engineering skills to build bridges, and the Dalarna Regiment served as sappers both in Stenbock's and Charles XII's marches. In July 1702 Charles XII and his main army caught up with Augustus II at the village of Kliszów, northeast of Kraków. Mörner and Stenbock reunited with the main army on the evening of 8 July. On the following morning Charles XII and the main army attacked Augustus II's Saxon and Polish troops. Stenbock was stationed with the infantry on the center of the first line of attack, under the command of lieutenant general Bernhard von Liewen. When Saxon and Polish cavalry attacked the Swedish left wing, Charles XII reinforced it with some cavalry squadrons and with Stenbock and the Dalarna Regiment. The cavalry attack was repulsed, and the Swedish main forces advanced into the Saxon camp, took control of the Saxon artillery, and threatened to encircle the Saxon center. Augustus II was forced to retreat, and lost about 4,000 men, while the Swedish losses were estimated at 1,100 men. Later, Stenbock recalled the battle as the most difficult he had ever experienced.
