By the 11th, Napoleon's corps were spread out in a wide net to snare Mack's army. Nicolas Soult's IV Corps reached Landsberg am Lech and turned east to cut off Mack from Tyrol. Jean-Baptiste Bernadotte's I Corps and Louis Nicolas Davout's III Corps converged on Munich. Auguste Marmont's II Corps was at Augsburg. Murat, Ney, Lannes, and the Imperial Guard began closing in on Ulm. Mack ordered the corps of Franz von Werneck to march northeast, while Johann Sigismund Riesch covered its right flank at Elchingen. The Austrian commander sent Franz Jellacic's corps south toward Tyrol and held the remainder of his army at Ulm.
