Stanisław Żółkiewski
In June 1610, De la Gardie and Dmitry Shuisky departed from Moscow in order to lift the Polish–Lithuanian Siege of Smolensk. The campaign ended with most of De la Gardie's forces defecting to the Polish hetman Stanisław Żółkiewski at the Battle of Klushino in 1610. After this, De la Gardie's remaining army during that summer returned to Vyborg, Finland (then part of Sweden).
