3rd Austrian army – advance to Dorfen

7th French army – garrison Essenbach
8th French army – defend Landshut
9th French army – regroup and resupply at Dorfen

End of battle of Landshut

The Bavarian army held a very strong position between the city of Landshut and the river Danube.   The river was not fordable, and could only be crossed by using one of the three bridges available.

The Austrian CinC decided to attack the centre bridge which led directly to the city.   But to do so he would have to secure the one bridge available.   He took command of the elite division of 5 corps, and the artillery of 6 corps.   The artillery would deploy either side of the bridge and destroy the Bavarian artillery dominating the bridge.

On his left 4th corps would be ordered to attack along the narrow area right of the river, take the bridge and attack the city from the right.

The Bavarians defeated this plan by simply retreating out of artillery range, but leaving their guns within range of their side of the bridges.   Unable to destroy the enemy guns, the Austrians could not risk a cavalry assault over the bridges.

The only casualties were to 4th Austrian corps artillery, who suffered 10% casualties.   They lost their morale test and routed, taking a supporting infantry brigade with them.

An easy, but very convincing, victory for the Bavarian army.

Comment

When I created the map for this campaign phase I did not anticipate how difficult it would be to attack across a defended river line.   But once it became obvious I used the opportunity to test the rules and decide whether it was possible or not.

I only use major rivers in my campaigns, and consequently wargames.   They would not be fordable in real life, and are not so in my campaign either.   They can only be crossed by the use of a bridge, but I do allow more bridges than would perhaps be normal.   My table is three scenic squares wide, and I allow one bridge on each square.   The exception is on bends, where I consider that the current would be too fast for a bridge.

Because both armies are more or less equal in size, to take a bridge the attacker would have to destroy the defending artillery, or at least make them retreat.  This can only do done by counter battery fire.  

In my new rules 12 pdr guns require 5 or 6 to cause casualties, 9 pdr guns require 6, and 6 pdr guns must be at close range.   10% casualties to the crew reduce all of these by 1.   Therefore a crew with casualties can only hit enemy artillery at long range if they are 12 pdr, 9 or 6 pdr have to move to close range to do so.   When the defenders are behind a river the defending artillery can remain out of close range (4”) of the enemy guns, but remain within close range of their end of the bridge.

In this game four of the six corps artillery had 10% casualties.  Only two, both of which were 12 pdr, had no casualties.   Both were on the right side of the table.   22nd Bavarian corps deployed in the river bend, from where they could hit the Austrians as soon as they advanced beyond the hill.  

On the right bank of the river the Bavarian CinC commanded two brigades of cavalry, supported by two brigades of infantry.   He would be supported by the artillery if the Austrians tried to attack that side of the river.

4th Austrian corps would have to force the Bavarian gunners to retreat before they could risk moving down from the hill.   Otherwise any attack on the exposed right bank must result in heavy casualties before they even reached the Bavarian cavalry and infantry.  They would also have to reduce the Bavarian superiority in cavalry, before their own cavalry could advance.   All of this required them getting their 12 pdr artillery into action without being charged by the Bavarian cavalry.

They attempted to do so by deploying it on the far right, out of range of enemy cavalry and artillery.  They could then man handle it into range of the enemy cavalry, and force them to surrender.  They could then engage the enemy gunners, and hope to defeat them also.  This would all require a lot of good luck – which they did not have.

As soon as 4th Austrian artillery were in position the Bavarian cavalry retreated out of artillery range.  The Austrian gunners then manhandled their guns into range of the Bavarian gunners; however this allowed the enemy to fire first.   The Bavarian gunners needed 5 or 6 for a hit – they rolled 5.    The Austrian gunners needed 5 or 6 to make their morale – they rolled 1.   The gunners routed into the supporting infantry brigade, who routed with them.

I was the Austrian player, and found the game really interesting.   It was always going to be very likely that I would lose the game.   Even if I could force a crossing at one of the bridges, the French player could bring overwhelming infantry and cavalry against my bridge head.   But I really enjoyed the challenge of trying to find a weakness – even though I failed to do so.   And Jan (the French player) simply retreated her cavalry and infantry out of range of my artillery, whilst leaving her guns within range of her end of the bridge.

Great game, but I will take care to ensure this does not happen again.   In future I will ensure that my rivers do not stretch across the width of the table, and thus allow the attackers an opportunity to outflank them.

  1. Thistlebarrow,

    A bridge assault is always a fraught operation and this battle is an excellent example of that. From a glance at the campaign map, it looks as if the Austrians didn’t have much of an alternative option if they wanted to get across the Danube.

    I look forward to seeing what happens next.

    All the best,

    Bob

  2. Hi Bob

    Happy New Year

    This game has convinced me that trying to cross a defended river is too difficult to wargame.
    I think the only way it would be possible would be one of the three attacking corps to cross the river before the battle started. This would represent an established bridgehead. I am not sure it would work, but it would be worth a try

    regards
