Mack advanced with his army, because Austrians wanted to establish control over Bavaria before facing the French. He also believed that Austrian security relied on sealing off the gaps through the mountainous Black Forest. Plus, Mack believed that the French would not violate Prussian territory. Napoleon didn't even expect Austrians to stay around Ulm, after he executed that famous maneuver. In fact, the whole operation was at risk. Napoleon thought that Mack would try to retreat towards Vienna or Tyrol, but he didn't. So majority of the French forces were on the right bank of the Danube and there was little on the opposite bank. That was perfect opportunity for Austrians to cross Danube and escape, which Mack failed to use.I don t understand why the allied didn t win this war.The English could debark in Belgium,and the Austrians had just to retreat-instead of stationing in Ulm-in the direction of the Russians,and after joining them,waiting for the entrance of Prussia in the war.
However, Kutuzov managed to pull off his retreat and Napoleon was in really dangerous situation. Allies now had advantage over him and with each new day their positions became stronger. More and more allied forces gathered towards the main theatre of war. Russians and Austrians would achieve great numerical superiority over Napoleon, if they were patient enough. However, Alexander I was still young and dreamed of military glory. Napoleon also managed to bait them into attempting to crush the French army with 1 decisive battle and not through attrition.
Prussian diplomat was actually heading to Napoleon with ultimatum. But when he arrived, Austerlitz had already happened.
Austrians Netherlands ( Belgium ) was also conquered by France at that time.
