Rosenheim Campaign – Day 2

Campaign Map on 4 October 1813
In the north 10th Bavarian corps has a bridgehead on the Traunreut road
Further south 9th and 11th Bavarian corps force a crossing and take Rosenheim.
In the centre the Austrians retreat and take up position in front of Traunstein.

2nd Austrian corps have orders to hold the river Isar
They attack to drive 10th Bavarian corps back over the river.

Battle of Wassenburg 
End of Move 1
The Bavarians hold the right bank of the river Isar
They have left one brigade to garrison Wassenburg
 That town is out of sight to the left

The Austrians have orders to hold the river
They move to drive the Bavarians back over the river
They have detached one brigade to garrison Traunreut (on the right)

After a determined battle both sides suffer heavy casualties
However the Bavarians still hold the bridge at nightfall and claim victory
End of move 9
Austrians move first
The Austrians have routed the Bavarian cavalry and artillery (on left of photo)
The artillery hit the square and cause 10% casualties
All three infantry brigades move forward, with the cavalry in support

Bavarians move second
The square pass their morale test for the artillery casualties
They must remain in square because of the threat of Austrian cavalry
The other two brigades are in line
They all wait for the enemy to approach within musket range
End of move 10
Austrians move first
The artillery are screened by their own infantry
Unable to fire they limber and move forward                                
The grenadier reserve move up to support the two brigades in line
The cavalry also advance, but keep out of range of the enemy square
The infantry nearest the camera move forward and fire on the square
The Bavarian infantry lose this one sided firefight and rout

Bavarians move second
The right hand infantry brigade move forward to engage the enemy line
They are elite light infantry and rout the Austrian conscript brigade
The Austrians rout through the grenadier brigade behind them
The grenadiers fail their morale and are shaken
The left hand brigade must test morale because of the rout
They fail and join the rout
The cavalry fail their morale for the rout and are shaken

At the start of move 9 it appeared that the Austrians must win the battle.
They had cavalry, artillery and three infantry brigades
The Bavarians had three infantry brigades, one had to remain in square

By the end of the Austrian move it seemed even more certain they must win
They had routed the enemy square for the loss of only 10% casualties

However the two Austrian brigades in line had blocked the gunners line of fire
They also prevented the reserve grenadier brigade from closing with the enemy
Even the cavalry had to take a wide swing to get around the flank of the line

All of this gave the Bavarians a very short window of opportunity
They only had two infantry brigades left to hold the whole Austrian corps
However one of these brigades was an elite jager brigade

The jager moved forward and engaged the nearest infantry brigade in a firefight
This was a conscript brigade, and no match for the jagers.
After a short exchange the Austrians broke and ran

The grenadier brigade was directly behind the conscript brigade
They failed their morale test and were shaken

The rout caused the third brigade (who had routed the square) to test their morale
They also failed, and routed

This caused the nearby cavalry to test their morale
They also failed and were shaken

With only the limbered gunners still formed the Austrian attack had ground to a halt
It would not be possible to rally and regroup before nightfall

Meanwhile the two Bavarian infantry brigades still held the bridge

Against all odds the Bavarians had won the battle.

Campaign Notes
Though a small battle with only one corps per side, this proved to be a very enjoyable wargame.    It is also a very good demonstration that the battle is not won until the last shot is fired.
