[11] The Austrians expected the main battles of the war to take place in northern Italy, not Germany, and intended only to protect the Alps from French forces.
[13] This simple but improbable explanation for the Russian army being far behind the Austrian is dismissed by scholar Frederick Kagan as "a bizarre myth".
After crossing the Rhine, the greater part of the French army made a gigantic right wheel so that its corps reached the Danube simultaneously, facing south.
He accordingly changed front, placing his left at Ulm and his right at Rain, but the French went on and crossed the Danube at Neuburg, Donauwörth, and Ingolstadt.
[17] Unable to stop the French avalanche, Michael von Kienmayer's Austrian corps abandoned its positions along the river and fled to Munich.
He was defeated in the Battle of Günzburg by Jean-Pierre Firmin Malher's division of Michel Ney's VI Corps which was still operating on the north bank.
His army was blocked by Pierre Dupont de l'Etang's VI Corps division and some cavalry in the Battle of Haslach-Jungingen on 11 October.
Mack ordered the corps of Franz von Werneck to march northeast, while Johann Sigismund Riesch covered its right flank at Elchingen.
[21] On 14 October, Ney crushed Riesch's small corps at the Battle of Elchingen and chased its survivors back into Ulm.
Jellacic slipped past Soult and escaped to the south only to be hunted down and captured in the Capitulation of Dornbirn in mid-November by Pierre Augereau's late-arriving VII Corps.
