In the Battle of Leuthen or Lissa, fought on 5 December 1757, Frederick the Great's Prussian army used maneuver and terrain to decisively defeat a much larger Austrian army under Prince Charles of Lorraine, thus ensuring Prussian control of Silesia during the Seven Years' War.
While Frederick the Great was campaigning in central Germany, routing a combined Franco-Imperial army at the Battle of Rossbach, the Austrians had managed to slowly retake Silesia. Frederick had arrived on 28 November to find that the primary city in Silesia, Breslau (Wrocław), had just fallen to the Austrians. He arrived near Leuthen (Lutynia) to find an army that was twice his size. He realized that he must either win a great victory or suffer a horrible defeat. The commanders in charge of the Austrian army had earlier argued about whether to march out of Breslau to face Frederick, Prince Charles had won the argument. The weather was foggy, but the entire area had once been a training ground for the Prussian army, so Frederick the Great knew the terrain intimately.
