Michel Ney's VI Corps smashed Riesch on 14 October in the Battle of Elchingen and forced the survivors to retreat to Ulm. Murat set out in pursuit of Werneck. On 16 October, there was a clash between Ney's cavalry and Prince Friedrich Franz Xaver of Hohenzollern-Hechingen's division at Langenau. Murat caught a 5,000-man brigade under Rudolf Sinzendorf at Herbrechtingen on 17 October and wiped out half of it. On the same day, Ferdinand's cavalry fought off the French cavalry at Nördlingen and there was another clash with Werneck's troops at Neresheim. Murat and Ney with 28,000 troops cornered their adversary at Treuchtlingen on 19 October. On that day Werneck capitulated with 15,000 troops, 28 guns, 12 colors, two standards, and four generals. Murat demanded that the terms include nearby Austrian units and Werneck accepted. Because of this the artillery reserve also surrendered. Hohenzollern refused to join in the capitulation and got away with 10 squadrons of cavalry. Ferdinand also managed to escape to Bohemia with Karl Philipp, Prince of Schwarzenberg and 12 squadrons of horsemen. On 20 October Mack surrendered at Ulm with 20,000 infantry, over 3,000 cavalry, and 59 guns.
