Tilly was then crushed at Breitenfeld in 1631 by the Swedish army of King Gustavus Adolphus. A Swedish arquebus bullet wounded him severely at the Battle of Rain, and he died two weeks later in Ingolstadt. Along with Duke Albrecht von Wallenstein of Friedland and Mecklenburg, he was one of two chief commanders of the Holy Roman Empire’s forces in the first half of the war.
