Battle of Breitenfeld
The sudden death of Banér in May 1641 recalled Torstensson to Germany as generalissimo of the Swedish forces and Governor General of Pomerania. He was at the same time promoted to the rank of Field Marshal. In 1642 he marched through Brandenburg and Silesia into Moravia, taking all the principal fortresses on his way. On returning through Saxony he crushed the imperial army at the second Battle of Breitenfeld on 23 October 1642.
