Battle Summary

The Bavarians started the battle with a small advantage in numbers of infantry
But the Austrians held a very strong defensive position
They only had to hold the city of Ulm to win the battle

Oudinot could see that the strongest Austrian corps opposed his left wing
He ordered them to hold the hill

He could also see that the Austrians had massed their artillery to cover Ulm
An approach against the city must fail

So he ordered 10th and 11th corps to attack the Austrian left wing.
He massed his artillery between the woods and the farm
But this left insufficient space to deploy the two corps
10th would lead the attack, supported by 11th corps

The artillery concentrated on the grenadier brigade supporting the artillery
The elite Austrian brigade held their ground despite 30% casualties

Then 10 Bavarian cavalry were ordered to charge the gunners
They suffered 10% casualties and retreated shaken
In doing so they blocked the advance of 11th corps

Meanwhile the infantry advanced and screened their own artillery
They suffered casualties from the enemy artillery
Two Austrian brigades now came forward and engaged the massed column
The leading Bavarian brigade routed with 30% casualties
They routed into the supporting brigade, who also routed with 10% casualties
The wide spread rout prevented 11th corps from advancing

It was now 6pm and too late for Oudinot to organise a second attack.

With the loss of one of his three corps he accepted defeat and ordered a general retreat.

The Bavarians lost 1800 casualties and two brigades in rout
The Austrians lost 1200 casualties
