Heretical Gaming is my blog about my gaming life; currently concentrating on a re-fight of the entire Peninsular War, but with the odd foray into ancient, medieval and WW2 battles.

Polemos General de Division AAR: Battle of the Gebora 1811

This morning I had a go at re-fighting the Battle of the Gebora, a Peninsular War battle which took place between a French Army commanded by Marshal Soult and Marshal Mortier and a Spanish Army under the command of General Mendizabal.  I used the scenario first published in Miniature Wargames 333, published Jan 2011.


The scenario gives all the details necessary for a refight of the battle.  It has a clear, straightforward map (with a map scale thankfully!) and simple orders of battle.  I then supplemented this scenario with a few details, particularly concerning troop quality, to this scenario and refight of Gebora using the General de Brigade rules.

And here is a link to Oman's description of the battle.

Imperial French Army

C-in-C: Marshal Mortier (Decisive)

Mortier's tactics in the battle were masterful


Infantry Division: Gen Girard (Capable):
Phillipon's Brigade: 6 Infantry Bns (6 bases, Trained SK1) (working as two separate regiments)
Gaud's Brigade: 3 Infantry Bns (3 bases, Trained SK1)
Artillery: 2 x 8lb Foot Btys

Cavalry Division: Gen Latour-Maubourg (Decisive)
Briche's Brigade: 2 Veteran light cavalry bases, 3 Trained light cavalry bases, 1 Raw light cavalry base (Juramentados cavalry)
Eclat's Brigade: 5 Trained dragoon bases, 1 Veteran light cavalry base
(n.b. I messed this up in the game and attached the Raw LC to the dragoons rather than the Veterans)

Spanish Army

C-in-C: General Mendizabal (Plodding)


Mendizabal was humilitated in the original battle, but later redeemed his reputation


2nd Infantry Division: Gen Virues (Plodding)
Espana's Brigade: 1 Trained SK1 Infantry base, 2 Trained SK0 infantry bases, 2 Raw SKo Infantry bases
Virues' Brigade: 1 Trained SK1 Infantry base, 4 Trained SK0 Infantry bases, 3 Raw SK0 Infantry bases
Artillery: 1 x 8lb Foot Bty, 2 x 6lb Foot Btys

1st Infantry Division (counted as a brigade due to its small size)
1 Trained SK1 infantry base, 4 Trained SKo infantry bases

Spanish Cavalry Division: Gen Boutron (Plodding)
Cavalry Brigade: 3 Raw Dragoon bases
Dragoon Brigade: 3 Raw Dragoon bases
Light Cavalry Brigade: 2 Raw Light Cavalry bases
Hussar Brigade: 2 Trained Light Cavalry bases
Portuguese Brigade: 5 Raw Light Cavlry bases

The Deployment:

View from behind the Spanish position (i.e. West to East).  Spanish infantry hold the ridge, whilst the Allied cavalry are in the rear.  The tents and so on are the remnants of the Spanish camp.


View along the line from the South.  Girard's Division are approaching from the East, whilst the French cavalry have completed an outflanking movement through the morning mist and are approaching from the North.

The view from behind the Spanish infantry, looking at the French fusiliers down the slope

And lastly the view from the North, with the French cavalry emerging onto the table from out of the mist.
 The Battle

The French cavalry advance along the ridge so the Spanish infantry rush into position to secure their left flank

The view from behind the French cavalry: the Spanish cavalry have quickly formed lines to try and offer resistance

The French infantry advance up the hill towards the Spanish defences

First clash: French Dragoons crash into raw Spanish light cavalry


The wider context of the clash

The Spanish cavalry are quickly routed and flee

The French Dragoons maintain their perfect order

The Spanish 1st Division infantry prepare to receive the French infantry, reserving their fire..

French infantry and cavalry advance to threaten the Spanish left, which maintains its determination to hold on

The Spanish Horse and Dragoons form a line to try and restore the situation

The French cavalry fearlessly crash into the Spanish cavalry


Most of the Spanish cavalry flee, but the central Spanish regiment holds on - and pushes back their French opponents


The Spanish light cavalry attack, hoping to regain the initiative

The French Dragoons, victorious but scattered, are engaged by the Portuguese cavalry

The Spanish light cavalry flee when they realise that they are left alone

The swirling cavalry battle continues, with regiment after regiment of Spanish cavalry fleeing the wrath of the French Dragoons!

The Spanish and French infantry face off

A Spanish infantry counter-attack causes severe losses to the French left-hand attack and throws it back down the hill

The last Iberian cavalry holds out against the French Dragoons

The overall situation: the Iberian cavalry is on its last legs (foreground, note the red shaken markers amongst the Portuguese cavalry); the Spanish infantry on the right is advancing; the Spanish infantry on the left is suffering from the French artillery, but holding on with some determination


A last hurrah for the Spanish Dragoons! They charge home but cannot break the French Dragoons - a melee ensues.

However the remainder of the Spanish and Portuguese cavalry is defeated...

A closer view of the French Dragoons, scattered after their multifarious successful combats

The French cavalry reforms, nearly surrounding the Spanish infantry

The pressure increases...but the French infantry are disordered as they puff and clamber thewir way up the steep slope...

So Mendizabal launches an audacious counter-attack in the style of the British Guards! The central French regiment is utterly routed!!  The right-hand regiment (left of picture) just manages to retain its morale...

This forces Mortier to thrown in a big cavalry charge to restore the situation...which is in turn entirely successful! The left-hand Spanish brigade is destroyed and its guns overrun.  Spanish morale collapses and those who can't flee surrender.

A wider shot - the battle is over
 Results:
A decisive French victory, just as occurred in the real battle.  However, the Spanish really did nearly pull off an unlikely victory by unleashing the charge down the hill against the French infantry.  The Allied cavalry was marginally more effective than in the historical prototype, although this only meant that some units charged home before being defeated, rather than routing without much of a fight.

Game Notes:
A very interesting game - more interesting than I had perhaps guessed.  This game brought home quite a few points to me about scenario design and effects calibration.
The MW scenario did (very usefully) rate the commanders, but didn't rate the troops directly, so I used the ratings from the General de Brigade scenario, converted to Polemos.  However, Polemos uses fewer classes than General de Brigade, but relatively the differences are stronger.  Also in Polemos, slopes are considered very important (the same effect size as artillery support).  Steep slopes are even worse for an attacker.  So whereas in the original battle, the French infantry could engage in a protracted firefight to weaken the Spanish, here the French were too vulnerable and the Spanish duly attacked successfully.  The French were literally 1 dice 'pip' away from a possible defeat at one point.  I imagine that in many current rules, certainly in rules I have played in the past, the odds would have been less in favour of the Spanish at this point.  Conversely, cavalry in Polemos are brittle.  The cavalry engagement came out reasonably similar to that of history, but cavalry must either surprise infantry or wait until they are disordered to charge successfully.  The French light cavalry were quite lucky that their charge came off in this refight.
If I do this one again, I may experiment by making the French infantry veteran.  Certainly, this would make the infantry fight more equal (essentially compensating for the slope, to some degree).  The mechanics would also allow more granularity in troop quality, if required.  As written, the basic factors in the rules are:
+2 for Veteran
-2 for Raw

So a veteran unit has a base 4-point advantage when attacking a raw unit, and 2-points when attacking a trained unit.  This is quite a significant level of modifier when the basic mechanic is an opposed D6 roll.

I used the Polemos General de Division rules on a 5'x3' table, using Baccus 6mm figures.

The Battle of Bassano: A Detailed Run-Through of Polemos General de Division

Yesterday I was asked to go through an example of a Polemos General de Division battle to show how it plays out on the table to help someone new to the rules understand what is going on. 



With that in mind, the aim of this post is to present a few turns of a complete Polemos General de Division game.  It is deliberately long and long-winded, in order to provide the clearest possible explanation.  That said, no doubt I haven't been clear at some point or I have done something  not in the rules because I have house-ruled it but played it so often I have forgotten that it is actually a house rule...

All comments and constructive criticism very welcome.

The Scenario
For the scenario I chose the First Battle of Bassano , fought on 8th September 1796 which took place between a French Army under General Bonaparte against an Austrian force led by Field Marshal
Wurmser.




 The scenario itself was only slightly adapted from one written by Andrew Sayce back in Miniature Wargames 121.



Adapting the Scenario
The typical difference between a Polemos scenario and a more standard ruleset is that generally a single base represents a single unit, and strength differences between units are ignored: instead the number of bases is calculated at an Army level.  Normally this makes absolutely no difference as every army's battalions were roughly the same strength, but not in this scenario: the Austrians had distinctly larger battalions.  So the forces ended up as follows:


The French Army:

C-in-C: General Bonaparte

1st Division: Gen Massena (Decisive)
1 x Light brigade: 3 bases of Trained SK2 infantry
2 x Line brigades: 4 bases of Trained SK1 infantry
1 x Line brigade: 3 bases of Trained SK1 infantry
Artillery: 1 x 8lb Foot Bty, 1 x 6lb Foot Bty

2nd Division: Gen Augerau (Capable)
 1 x Light brigade: 3 bases of Trained SK2 infantry
2 x Line brigades: 3 bases of Trained SK1 infantry
1 x Line brigade: 4 bases of Trained SK1 infantry
Artillery: 1 x 8lb Foot Bty, 1 x 6lb Foot Bty

Cavalry Division: Gen Murat (Decisive)
1 x Brigade: 3 bases of Trained light cavalry
Artillery: 1 x 4lb Horse Bty

Independent Cavalry Brigade (detached from Murat's Division)
4 bases of Trained light cavalry

The French force will generate tempo as: D6 + 4 (1 for each independent formation in the Army)
Its Army morale will be 10 (2.5 x number of independent formations)

The Austrian Army

C-in-C: FM Wurmser

1st Division: Gen Kheil (Plodding*)
2 x Line brigades: 4 bases of Trained SK0 infantry
1 x Light brigade: 3 bases of Trained SK2 infantry
Artillery: 1 x base of 8lb Foot, 1 x base of 6lb Foot

 2nd Division: Gen Reisky (Plodding*)
2 x Line brigades: 4 bases of Trained SK0 infantry
1 x Light brigade: 3 bases of Trained SK2 infantry
Artillery: 1 x base of 8lb Foot, 2 x bases of 6lb Foot

Grenadier Reserve
4 bases of Veteran SKo infantry

Light Cavalry Brigade
3 bases of Trained Light Cavalry

Light Cavalry Brigade
3 bases of Trained Light Cavalry

Uhlan Brigade
3 bases of Trained Lancers

Dragoon Brigade
5 bases of Trained Dragoons

*The actual formations in the Austrian force weren't known to the scenario writer, nor do they appear in the Napoleonic Wars Data Book, so I simply made up a typical structure with a couple of fictitious commanders.

The Austrian Army will generate tempo as follows: D6 + 7
The Austrian Army will have an Army morale of 17.5 (i.e. 2.5 x 7)

 Terrain Notes:
The high ground is classed as steep slopes
The watercourse is a river, only passable at the bridge
The built-up area is a town

 Scenario Special Rules:
The author suggests a -1 to all Austrian morale rolls to account for their poor morale and tiredness.  I will use this on all combat rolls, but not on firing or melee rolls to incorporate this.

Note on modifiers - when I go through the modifiers, I do them all from the perspective of the attacker or firer.  This is why you may see a '+' when the rulebook has a '-'. It makes absolutely no difference to the results, I just find it easier to count this way when playing solo.

I normally use individually-based figures now to indicate Tempo Points and Shaken levels but I have used black and red counters respectively in this game in order to make them more obvious (obtrusive?!) to the reader.


The Deployment

The Austrian forces are deployed at the bottom, French forces towards the top.  For the French, Massena's Division and the Light Cavalry Brigade are to the left of the river as we look at it, Augerau's Division and Murat's Division are to the right.  The two Austrian divisions are deployed each side of the river also, with the cavalry and grenadiers to the rear.


The view along the lines, from the French left towards the river.  Augerau's Division occupies the high ground looking over the town and river valley
 Turn 1 - Tempo Bidding:
Both sides rolled for tempo:
French roll 6 + 4 =10.
Austrians roll 5 + 7 =12.

Then both sides bid:
French bid 5.  Austrians bid 5.  Napoleon has 5 TPs to allocate, Wurmser has 7.
As a tie on the first turn in the game, both sides roll to see who gets the tempo on the first turn. Napoleon wins.

Turn 1 : Tempo Player Bombardment

Augerau's artillery bombards unsuccessfully (rolls 6, +1 for extra base, +1 for extra target base = 8, no effect)

As does Massena's.


Turn 1 - Tempo Player Moves Generals & Issues TPs

Napoleon gives two TPs to Massena (foreground), a single TP to the Cav Bde commander. Massena converts this into 10 order points, the Cav Bde commander into 2 order points.

Napoleon gives one TP each to Murat and Augerau, who generate 5 and 4 TPs respectively.
Turn 1 - Tempo Player's Movement
(there were no attacks in this turn)
Massena uses an order point to move his light brigade (see the extra skirmishers) forward

Massena uses two more order points to move an infantry brigade parallel to his light brigade

Massena uses a fourth order point to move forward half of a reserve brigade towards the French right flank

He uses a fifth order point to move the other half of the reserve brigade behind the advancing light infantrymen

And he uses a sixth order point to move his last infantry brigade up towards Napoleon and his artillery.  The artillery can't move since they carried out ineffective bombardment fire.

Augerau uses his first order point to move forward his light brigade.

He uses his second order point to move forward the supporting brigade

He uses a third order point to move forward half of his reserve brigade

And he uses a fourth order point to move the other half of the reserve brigade too

He doesn't have sufficient points remaining to advance his last brigade

The independent cavalry brigade moves forward.  All turning must be done by wheeling.  I use a homemade marker with distances of 1/2BW and 1BW marked on for ease.

Murat moves forward his division in two groups
Turn 1: Non-Tempo Player Bombardment
The Austrian artillery bombards the French. Rolls 5, gets cease fire miss next turn's bombardment (indicated by smoke)

The other Austrian artillery bombards Massena's advancing troops: Rolls 6, +1 for extra base firing, +1 for extra base target, -1 for target moved last turn = 7 (no effect)
Turn 1: Non-Tempo Player Moves Generals & Issues Tempo Points
Wurmser gives two TPs to the Uhlan brigade.  Because it is further than 6BW from Wurmser, each TP only generates a single order point.

A TP is given to Kheil (located next to the bridge), generating 3 order points.


And two TPs are given to the Grenadiers, generating 4 order points.
Kheil moves his infantry up to support his artillery
Turn 1: Non-Tempo Player Movement
(There were no attacks - the picture above belongs to this section too (formattting issue!)

The Grenadiers move up, some of them along the road to reinforce the town of Bassano.
Turn 2: Tempo Bidding
Napoleon bid 2 of his 10 Tempo points, Wurmser bid 6 of his 12: The Austrians therefore have the tempo:

Turn 2: Tempo Player Bombardment

Austrian bombardment on the right flank: no effect

Austrian bombardment on the left forom Kheil's artillery: rolls 10, +1 extra base, +1 target base, -1moved = 11, target must retire or be shaken.  The French retire 1BW (see gap in French advance)

Turn 2: Tempo Player Moving Generals & Issuing TPs

Wurmser gives 2 TPs to one of the groups of Dragoons - because of range, order points havled to 2.

1 TP given to the Grenadiers for 2 order points

1 TP given to Kheil, 1 TP given to a Lt Cav Bde
Turn 2 - Tempo Player Movement
(no attacks this turn)
Movement - Austrian Dragoons move up to secure the Austrian right flank

Austrian Grenadiers enter Bassano to support the Grenzers

Not a great shot here, but Kheil has brought up some of his reserve infantry to give rear support to his artillery; the grenzers and light cavalry on the left both advance slightly forward
Turn 2: Non-Tempo Player Bombardment
Non-tempo player bombardment: Augerau's artillery bombards without effect (and Massena's artillery doesn't achive anything either)
Turn 2: Non-Tempo Player Moves Generals and Issues TPs
Napoleon issues his tempo points: 2 to Massena (10 order points, 1 to each group of the independent Lt Cav Bde (4 order points)

3 to Augerau (12 order points) and 1 to Murat (5 order points)
Turn 2: Non-Tempo Player Attacks
Attack! French infantry attack Austrian cavalry, costing 3 order points.. French roll 4, Austrian roll 3. -1 to Austrians for morale (scenario rules).  No other modifiers from the general "Testing to Charge" table or from the "Infantry Attack on Cavalry" table.  French win by 2.  Check "Result" under the "Infantry Attack on Cavalry" table.  Infantry win = Cavalry retire 1BW.

And the Cavalry retire thus.
Turn 2: Non-Tempo Player Movement

Massena advances his 4-base infantry brigade for 4 order points.

Murat advances each of his groups for 2 order points per group.

Augerau moves all of his infantry groups (five) for a total of 10 order points.
Turn 3 - Tempo Bidding
Napoleon bids 7 and is left with 3 points, Wurmser bids 10 and is left with 2 points.  The Austrians retain the tempo.

Turn 3 - Tempo Player Moves Generals & Issues Tempo Points
(The Austrian bombardment was ineffective this turn)

1 TP to Kheil for 3 order points.  Note that he has moved and attached himself to the light cavalry.  He had just insufficient movement to attach himself to the Grenzers ahead of them)

1 more TP to the Grenadiers for 2 order points
Turn 3 - Tempo Player Attacks

Kheil orders his 3 Grenzer bases to attack for 2 order points.  Go to "Testing to Charge" and "Infantry vs Infantry" table. Roll: Austrian 6, French 4. -1 Morale, +1 Infantry Support, +2 Cavalry Support, -1 Defender secure flank, +1 Defender firing at close range (1/2BW): result: Attacker wins by 2. Defender shaken but may fire.  Go to "Firing" table.  Roll: French 1, Austrian 5, +2 first fire, -1 defender supporting base, -1 firer shaken.  Result of firing: no effect.

Go to "Outcome of Infantry vs Infantry Attack".  Side with greater number of shaken levels (here French defenders) fall back 1BW.  Fall back result indicates infantry take a second shaken level (indicated by red markers)

Remaining Grenzer battalion attacks the French, using same tables as above.  Roll: Austrians 5, French 3. -1 Austrian morale, -1 French infantry suppoer, +2 Cavalry support, +1 defender firing at close range.  Attacker wins by 3, defender shaken may fire.  Firing, roll: French 1, Austrians 2, +2 First fire, -1 firer shaken.  Result - no effect.

Check "Outcome of Infantry vs Infantry Attaxcks" - side with greater number of shaken levels falls back.  Note that the first French base falls back and pushes the rear supporting base backwards too.  Both gain an extra shaken point.  The leading French base "should" be at 3 shaken i.e. break (1 for shaken in the charge, 1 for the fall back, 1 for falling back into another base) but a base can only get 2 levels of shaken in one turn.
Turn 3 - Tempo Player Movement

Austrian grenadiers continue their slow (1BW per turn) move through the town.

Turn 3 - Non-Tempo Player Bombardment

French artillery bombards: rolls 8, +1 for extra base firing, +1 for extra target base. Result, target must retire or be shaken.  Target retires.  Augerau's artillery got a no effect result on the other flank.
Turn 3 - Non-Tempo Player Generals' Moves and TP Allocation

Napoleon gives 2TPs to Massena for a total of 10 order points.

1 TP to the independent Cav Bde for 2 order points.

Massena, leading in person, ordersthis brigade to attack (cost 6 order points)

Infantry attack artillery, look on "Testing to Charge" and "Cavalry/Infantry Attack Artillery" table. Roll: French 6, Austrians 4, +1 for General leading, -2 for Austrian infantry support, +! for French support, +! for poor Austrian morale   Result, French attackers wins by 3, Austrian artillery shaken but may fire.

Artillery fire conducted not as a bombardment uses the normal "Firing" table at close range.  Roll: Austrians 5, French 2. +2 for supporting artillery, -1 for shaken.  Result - target takes 1 shalen level.  Look on "Outcome of attacks on Artillery" - both sides shaken levels equal, foot artillery falls back 1BW taking their guns.

Falling back artillery takes another shaken level and then inflicts shaken level on the base to the rear it pushes back.  Supporting artillery retires along with the unit it was supporting but does not take shaken levels.

French general tests to see if he was hit. Rolls 9, -1 for being decisive, total 8 - no effect.  French infantry ends up next to Austrian infantry, but the next French infantry attack will be conducted upon them (by the two-base column on the top-right of the shot)


French conduct infantry attack as detailed previously.  Roll: French 1, Austrians 4, +1 poor Austrian morale, +1 skirmish level advantage, +3 defender fires at point-blank range.  Defender wins by 2, shaken but may fire.

Austrian infantry fires.  Roll: Austrians 3, French 4. +2 for first fire, +4 for point-blank fire, -1 for shaken.  Total +4, one shaken inflicted on target.  Check outcome of "Infantry vs Infantry": both sides with 1 shaken level, defender falls back 1BW.

The Austrian infantry falls back, inflicting a level of shaken into the rear supporting infantry base.
I didn't take a picture, but the French infantry carried out another attack on the Austrian Uhlans, achieving exactly the same result as previously.

Turn 3 - Non-Tempo Player Movement

French Light Cavalry advances down the road under the watchful eye of General Bonaparte.
Turn 3 - Outcome Moves

Massena's Light Infantry Bde must check its formation morale.  It has 3 bases, all of which are shaken.  Roll: 5, check table on formation morale page. 5 = +1, +3 for the 3 shaken bases = 4.  This is more than the number of bases in the formation, so the formation is spent.

The French infantry turn, spent.  They will move at normal rate towards their own baseline, hors de combat for the remainder of the battle.

Massena removes 1 shaken level from the infantry unit he is in base contact with.

Turn 4 - Tempo Bidding
Napoleon bids 2 TPs, leaving him with 8.  Wurmser bids 8, leaving him with 4.

Turn 4 - Tempo Player Moves Generals & Issues TPs

Wurmser issues all 4 Tempo points to General Kheil for a total of 12 order points.


Gen Kheil moves to lead his unshaken right-hand battalions in person and orders them to attack (2 order points)

The Austrian infantry attack the shaken French infantry. Roll: Austrians 1, French 3, -1 for morale, +2 for enemy shaken, +1 for general leading, -1 for skirmish differential, -1 for defender's secure flank,+3 for defender firing at point-blank range.  Total: +1, both sides act as ordered. Firing, roll: French 6, Austrians 1, +4 point-blank range, -1 shaken, French win by 8, Austrians break automatically.

The routing Austrian infantry fall back plus move normal move (2BW) for a total of 3BW.  Rear supporting base falls back (i.e. takes 1 shaken level, moves back 1BW facing the enemy). 

Austrian general tests for safety, is fine. n.b. I should have moved the victorious French forward at this point, but instead I moved them after the normal Austrian movement.  It made no differenc.

The Austrian artillery moves onto the bridge (1 order point)

The remaining order points are used to remove shaken levels

The French infantry is moved forward 1BW.
Turn 4 - Non-Tempo Player Bombardment

Rolls 9, +1 for extra base, +1 for additional target = 11: retire or be shaken

Austrian infantry retire as a result

Massena's artillery bombard, but roll 5, +1 for extra base, -1 for target moved = 5.  Cease fire for next turn.

Smoke indicates the cease fire.
Turn 4 - Non-Tempo Player Moves Generals & Issues TPs

3 TPs given to Massena (15 order points), 2 TPs given to the independent cavalry brigade, which Napoleon joins in person.

1 TP given to Murat (5 order points) and 2 TPs to Augerau (8 order points)
Turn 4 - Non-Tempo Player Attacks
Napoleon himself leads the charge of the French light cavalry down the road into the shaken Austrian infantry. Use "Testing to Charge" and " Cavalry Attack on Infantry" table.  Roll: French 4, Austrians 3, +1 Austrian morale, +1 General leading, +2 defenders shaken.  Cavalry wins by 5, defending infantry break.

French cavalry win, will follow up 1 BW then test to pursue at the end of the round.

Massena leads his infantry into another attack on the Austrian artillery using the same table as before.  Rolls: French 2, Austrians 3, +1 general leading, +1 poor Austrian morale, +2 artillery shaken, -2 artillery supprted by infantry, +1 attacker supported.  Attacker wins by 2, artillery shaken but may fire.  Firing, roll: Austrians 4, French 4.  +2 for supporting artillery, -2 for two levels of shaken - no effect.  Check on outcome - artillery has more shaken levels, breaks.

Artillery breaks, causing infantry behind to fall back.  Rearmost infantry has already lost 1 shaken from hit by fall back, then gets further shaken level as pushed into further Austrian infantry (very bottom of shot), which also loses a shaken level.  Supporting artillery retires 1BW to conform.


Remaining French infantry attack Austrian infantry with two shaken levels using same mechanism.  Roll: French 1, Austrians 4. +1 skirmish differential, +1 poor Austrian morale, +3 defenders firing point-blank.  Attackers win by 2, defender takes shaken level, may fire. 

Firing, roll: Austrians 1, French 2, +4 point-blakn fire, -2 firer's shaken levels, +1 defender's shaken level. Result +2, target takes a shaken level.  Outcome, each side has 2 shaken levels: attacker falls back 1BW.  Attacker now reaches 3 shaken levels, breaks.  Rear-supporting base falls back 1BW.

French units routing and retreating.  However, French follow-up move (1BW advance) after the defeat of the Austrian artillery brought them into contact with Austrian infantry.  New French attack conducted. Roll, French 3, Austrians 3, +1 for General, +4 for defender's shaken levels, +1 for skirmish differential, +1 for poor Austrian morale.  French win by 7, Austrians break automatically. n.b. The mechanism here could  be interpreted differently - see my comments at the end.



French advance again after breaking enenmy - note Austrian infantry in rear support fell back with shaken level.

French infantry tried another attack on the Uhlans.  This time the cavalry won, so the infantry didn't charge.

Turn 4 - Non-Tempo Player Movement

Augerau moves forward his two main brigades, plus his flanking brigade and two bases from his reserve.  Murat brings his groups back together.
Turn 4 - Outcome Moves

The right-hand Austrian brigade automatically went spent, with 6 points for 3 broken bases and 1 point for the last remaining shaken base, there was no possible morale roll which could save this formation.  The other brigade, with 3 points for 3 shaken bases rolled a 5.  This added 1 to the score, but 4 does not exceed its initial number of bases, so it remains in the fight.  Typically divisional artillery is ignored, becoming spent if the divsion it is attached to is spent.  You can incorporate it into a divsion or brigade structure without causing anything to break, however.

Summary:
I hope that this long walkthrough may be of some use to players who wish to give Polemos Napoleonics a go but feel that they are struggling to grasp the baasic mechanics.  Please feel free to ask me any questions and I will try my best to answer, or I will amend the post to show the answer.
If the author or any of the more veteran players want to correct something, please let me know, I'm not precious about changing stuff that I have misinterpreted.  I think that this walkthrough does show the many strengths of Polemos as a ruleset, as well as highlighting the weaknesses - primarily bases interacting in ways not fully described in the rulebook, particularly as outcomes of attacks.
Played on a homemade 5'x3' mat, using Baccus 6mm napoleonic figures and Total Battle Miniatures buildings.
