Campaign
Notes
For the first six days all went well for
Oudinot. He won the first three battles
and it appeared he could do no wrong.
The Austrians were pushed back and he managed to get three of his four
corps over the river Isar. He even took
Rosenheim, the campaign objective.
However to win the campaign he now had to hold it.
Oudinot needed time to consolidate his string
of victories, and establish his army on the east bank of the river. His corps were running short of supplies,
and he needed to reorganise his battle casualties
Despite his defeats Schwartzenberg found
himself in a much stronger position. As
he retreated he fell back on his depots.
Supply was much easier, and he could choose the point to launch his
counter attack.
He did so against Rosenheim and he drove the
Bavarians back over the river. He did
not immediately follow up. He halted on
the east bank to reorganise and resupply.
Using the river to mask his intentions, he
reinforced his northern wing and attacked Holzkirchen. The first battle was a limited victory, and
it required a second battle to complete the destruction of half the Bavarian
Army.
An Austrian victory was now certain. Schwartzenberg could have waited a couple of
days to concentrate his four corps in the south, and then crush the two
remaining Bavarian corps. Or, more
likely, Oudinot would simply retreat to avoid certain defeat.
However Schwartzenberg wanted a decisive and
overwhelming victory. To do so he took
a short term risk. Oudinot has two
badly shaken corps desperately holding Bad Tolz long enough to withdraw all the
remaining supplies held in the main depot there. The two Austrian corps available to attack
were also badly shaken. A battle in
such circumstances would be decided on the relative morale of the two armies. One bad move, or one bad dice throw, could
easily result in a major rout – for either side.
Schwartzenberg fought a very defensive battle,
even though he was the attacker. He
ignored the strong walled town and concentrated his attack on the enemy troops
south of the town. His first attack
ended in disaster. Half of 4th
corps ran away when their cavalry brigade lost a melee. But he was able to bring most of 1st
corps to support the remainder. It
worked and 12th Baden corps were routed.
When I write the summary with hind sight it all
seems very obvious and an easy victory for the Austrians. But it could so easily have gone wrong. Had they lost the first battle of
Holzkirchen, Schwartzenberg would have won the campaign.
It proved to be a very enjoyable wargame
campaign. All seven games were fairly
even and unpredictable. None, not even
the last one, were a lost cause for either side. This is not brought about by my fixing the
campaign in anyway. Two things dictate
who does what, and both are almost impossible to fix.
First the supply system punishes the victor
because he moves further away from his main depot as he pursues the defeated
enemy. The losing side falls back on
his established depots and not only finds supplies, but also the depot
garrisons.
Second battle casualties. It is possible to concentrate infantry
casualties within one brigade, and also to receive replacements providing the
corps does not move or fight. But every
brigade which suffers any battle casualties always retains 10% for the rest of the
campaign. This reduces the fighting
ability and also the morale of each brigade concerned. After three or four battles many brigades
will have such casualties. Future
battles then depend on the luck of the dice, particularly morale dice.
I always feel that the most recent campaign was
one of the best, and Rosenheim is no exception.
I would have liked the Bavarians to defeat the
Austrians at least once, but it did not detract from our enjoyment of either
the campaign or each wargame.
