 The Austrians flooded the battle with more cavalry and infantry regiments to Ulm-Jungingen hoping to score a knockout blow against Ney's corps by enveloping Dupont's force.Dupont sensed what was happening and preempted the Austrians by launching a surprise attack on Jungingen, during which he took as prisoner at least 1,000 of the Austrians.Renewed Austrian attacks drove these forces back to Haslach, which the French managed to hold.
