Campaign Summary – 1st September 1813

At first light General Vandamme crossed the river Inn at the head of 9^th French corps and entered Austria at Uttendorf.  

His leading division marched further east to enter Frankenburg at nightfall.

He was surprised that he encountered no resistance at all; indeed no contact with the enemy was reported throughout the day.

This advance brought the three French corps into line from Passau in the north to Altheim in the centre and Frankenburg in the south.

Marshal Oudinot has ordered that no more than one division should be in these forward positions, to avoid warning the Austrians of his impending attack.

The ease with which 9^th corps completed their advance was down to the cautious attitude of Archduke Charles

The Austrian commander in chief was unwilling to occupy either Uttendorf or Frankenburg because to do so would expose his men to both a frontal attack from the west and a flank attack from Braunau or Altheim in the north.

His deployment from Obernzell to Raab to Vockabruck meant that any French attempt to cross the river Inn at Obernzell or Raab would expose them to counter attack as they crossed the river.

It also meant that all three Austrian corps had secure flank support.

The weak point, as the French had already found, was that the French could cross the river at Uttendorf unopposed.
