Attempt on Machtigburg - an Imagi-Nation Mini Campaign, Part One

Attempt on Machtigburg, Part One - Introduction and Background

Reading the background to other wargamer's Imagi-Nation countries can be tedious, but reading about their activities can be stimulating - just look at the success of the Charles Grant family publications. I hope this series of blogs will fall into the latter category so I'll spare you too much "political" detail.

Project history
I started my Imagi-Nation armies back in about 2008 inspired by Henry Hyde's then new magazine "Battlegames" as a transition from my 28mm French and Indian War, so the nucleii were British and French armies of the 1750s.  I had just had a lovely holiday in the French Alps where one of my nieces lives and realised that the real province of Savoy (Savoie) offered me the potential I needed as it had French names and location on the French border with Switzerland and Italy.

Thus I could take the Games Workshop (basically late Medieval) fictitious campaign map for Warhammer games, which was based on Germany, and freely translate it. Forget Switzerland and my Savoy bordered Reikland. I created the "Duc de Deuxcheavaux"  (don't ask) as the ruler of Savoy who was thrusting and expansionist and looked to Louis XV to support his pretentions on Reikland's territory. The year was 1760 and France had lost a lot of colonial territory so was looking for revenge and replacement lands. Savoy could have French style imaginary units backed by real French historical units, though not strictly 1760.

Reikland, for its part, was the South-West "Elektorate" of "The Empire" and Count Gregorius (um, yes me when I choose to be) von Grunburg ruled the county bordering Savoy. Would you believe Gregorious favoured British style red uniforms? He could also call on any Germanic units that took my fancy, never mind that Prussia and Austria were at war most of the time! They were all nominally subserviant to "The Empress" in Vienna in my mind.

I first blogged about this back in 2011 with the Battle of Futonville  report

and the units and games have been featured a lot since, although I had a long break from early 2013 to mid 2016 forced by two house moves and the 2015 bicentennial of Waterloo. This coincided with the opportunity to try out Keith Flint's "Honours of War" (HoW) rules and along the way I had had tremendous stimulation from membership of John Ray's "A Military Gentleman of the 18th Century" Forum.

2016 was time to revive my campaign, which is always done by my trying to link most games by vague reference to the"map " which is now just in my head, and with characters and units that come and go as I pragmatically use them to suit the circumstances of the game. No one to please but me and the friends who I can persuade to partake :-).

Savoy's latest invasion of Reikland - Background
AMG led me to meet Ken Marshall who was happy to help me test HoW using the three test games in the rule book. By game 2 we dragged AMG member Guy Barlow along too and for game 3 brought in my old mate Kevin East. Each one was getting a bit larger and our confidence building.
All these have been fully blogged and with a rough background brief. Please see the links below if you need a reminder.
Battle of St Ulrich

Clash at Kutzdorf

Surprise at Spittelwitz

Spring of 2017 got me custom building a 10 x 6 foot terrain for Kevin's big weekend Napoleonic test game Battle for Hoeke Valley

and I desperately wanted to expand the scope of our 18th Century games so launched into my first original HoW scenarios using this terrain, adapted, as my excuse.

Attempt on Machtigburg - the concept
Inspired by Charles S. Grant's various handy books on mini campaigns, (see for example Caliver Books website Search for Grant books at Caliver) I came up with the germ of three ideas for games, getting bigger each time, to be played over the Summer and Autumn.

• A petite guerre style battle involving mostly vanguards composed of quite a lot of light troops; Savoy/French trying to secure, and Reikland/Imperial trying to block, a passage through a river valley on the way to Machtigburg
• Based on the tabletop territory gained by the vanguards, two armies of all arms, with the French force having to protect a siege train required for the siege of Machtigburg and Imperial force trying to destroy or capture them.
• A third battle based on the the outcome which would involve the biggest forces we could game with in a day and on the 12 x 6 foot battlefield left over from West Country Quatre Bras part One

This evolved into me and Ken playing "Vanguards in the Wahlental" the day before we both attended the splendid AMG 17 weekend at Kenilworth in mid-June. Here is an idea of what it looked like, Ken contributed  a fair amount of the figures.

A month later we used a lot of Ken's Prussian style Imagi-Nation figures and he continued as the Reikland/Imperial commander and we invited Kevin along while I enjoyed umpiring "Siege Train in the Wahlental". A couple of pics of that one.

For the third and final battle, in early October, I was a very lucky chap as both Ken and Guy provided most of the troops. These were a good part of Ken's completed Imagi-nation forces - an interesting mix of British/Hanoverian/Prussian and white coated "Austrians", and an unknown part of the total of Guy's historical 1740-50s style French, British and Hanoverian Western theatre armies. All these were Minden, Crann Tara or Fife and Drum figures. They were supplemented in places by my eclectic mix of historical and Imagi-nation regiments owing no allegiance to one style of manufacturer. We mustered about 1500 figures for the day. Probably about another 500 or more stayed on my shelves for another time.  Better yet we were joined by Gloucestershire "locals" Roy Boss of Cirencester, and HoW author Keith Flint of Northleach.   Again I was GM and umpire/tea maker, which is my favoured role.
And now some taster pics from the "Battle of Edelstein"

That should give you some idea of the scope of what I expect to be describing over the next few weeks. (Though not all at once as I feel some Hussarette paintings beckoning to be shown!)  I'll include the full briefs as Downloads in the Imagi-Nation sidebar  as I go along.
 I will leave you with the map of the Wahl Valley I devised to use the adapted Napoleonic terrain for the first two games. Please click to expand.

Map of the Wahlental - if the names intrigue bear in mind this terrain was devised in the last week of May in the UK :-)

Third HoW test game - Spittelwitz

(NB: For reasons unknown to me Blogger failed to allow me to "Preview" this post at all so apologies if you find any of the formatting or typos irritating, or any of the photos of inadequate quality. Please let me know in a comment if so.)

It was nearly six months since our previous Honours of War test game Clash at Kutzdorf and I think Ken and Guy, like me, were both keen to try something bigger and see if we could get it finished in a day's game. Since this was scheduled as near as possible to our joint birthday weekend Kevin was invited too. It was his first "serious" foray into mid 18th century wargaming.
Thanks to the good company, the pub lunch, and birthday cake provided by the Duchess d'AreteDuchene the day proved far from serious; here is a "selfie" near the start.

The scenario is called "Surprise at Spittelwitz" but it's no surprise to anyone who has the rule book as the the map clearly shows the Blue Forces ready to take Red in their open flank across a river. However, I hope I managed to build in some fog of war by expanding the armies to fit my 8ft x 6 ft table, changed the composition while keeping a balance of small, standard and large units and made them of differing qualities. There was also a fair sprinkling of Dashing generals and the Blue (French) force had a Lieutenant General as befitted the larger army and two wargamers.

As before I set this within the context of my ongoing Imagi-Nations contest between the French -backed troops of "Savoy" and the great variety of Germanic types backed by a loosely Austrian Empire with the Elektorate of Reikland as its front line with Savoy.

Here is the map of my terrain, showing the deployment zones I gave to Ken's Reikland army. It also gave him an indication of the Savoy deployment but without the flanking force. The Savoy map for Guy and Kevin gave them areas D and E more or less as in the book scenario. You will see I added a camp as I thought it appropriate for a force having to man defences and it justified more Red troops as well as another objective for Blue.

So this is a generic version of the tailored briefing given to both sides

4th June 1760

Background 

The Chevalier de Neuvalee, under direction from Count Deuxchevaux of Savoy, failed twice in his attempt to break across the border into Grunburg county of the Elektorate of Reikland. Those were the two actions at St Ulrich.  A day later Neuvalee had retreated to high ground overlooking the village of Kutzdorf where he withstood an attack by a force under the Count of Grunburg. However his army got a bit distressed in its counter attack but nevertheless succeeded in giving Count Grunburg a bloody nose. In the following week Neuvalee spent time resting and regrouping the vast majority of the Kutzdorf force and greeted the arrival of his master, the Duke of Deuxchevaux. The latter has taken command and brought considerable reinforcements of his own army, plus a contingent of Royal troops, and two Legions of mixed units in the service of France. This is a considerable force of 12 battalions, 15 squadrons (in 5 regts) and 5 batteries of artillery. Such is the faith King Louis has in Deuxchevaux that the cavalry brigade consists of particularly fine troops. Neuvalee becomes second-in-command, with Lieutenant-General status, and the brigade commanders from the Kutzdorf battle have recovered from wounds and taken commands in this new army.

The Imperial force retreated back into Grunburg county with the Count taking umbrage and recalling all his own troops to regroup at Grunburg city. Word quickly reached the Empress who, within a week, ordered General Von Erickson forward with a new force to defend the line of the River Triebisch and stop any attempt at invasion. 

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>

Savoy/French Objective

The aim of your army is to mount a successful crossing of the river, take the high ground beyond and see off Erickson’s force while not depleting your own force unduly. This will be the precursor to pursuit on towards Grunburg City.

In game terms that means getting the Imperial force to reach it’s Army Point limit before you do. To assist that there is 1 Army Point lost if he loses the Spittelberg and 1 lost if you trash his camp. (Camp is considered trashed if at least 8 out of 12 tents are touched by a base of your troops for one Move)

Local Intelligence

Erickson’s force is a fair amount smaller than yours consisting mainly of solid musketeer battalions, and he only has two batteries of artillery plus a couple of units equipped with battalion guns and some cavalry.  Some of the elements from the Kutzdorf battle - such as light infantry and grenadiers are known to be in small numbers in the front line woods and redoubts and also Spittelwitz town. They are expected to be alert to the possibility of your attack. The rest of the enemy can be expected to be deployed up to the red line in the rear on the map and may not be on full alert. Both hills are defended by a line of entrenchments. The camp has no obvious defences but is expected to be defended by less reliable troops.

Deployment

The blue line shows your deployment limit and the map gives some idea of the size of standard units, please use these and allow a bit more space for large and less for small units. 

The Legion de la Morliere must be set up in Area D. The remainder of your army is set up anywhere North of the blue line marking Area E. You may set up some units off the table at the start  if you wish (eg. due to space considerations or second line distance from front line) but they must be marked, to scale, on the map. Units may be in line or column of march, artillery may be unlimbered and ready to fire or limbered up .

...............................................

Reikland/Imperial Objective

Imperial engineers have been hard at work preparing defensive positions around and behind Spittelwitz, shown on your map. There have not been sufficient resources yet to cover the small bridge directly to your East. Erickson’s objective is to hold off the enemy force and inflict sufficient losses on it to thwart this invasion attempt, while preserving his line of communication and camp intact. In game terms that means getting the enemy force down to his Army Points limit before you do. Beware, that loss of Spittelberg and your Camp will lose you 1 Army Point for each.

Local Intelligence

Deuxchevaux’s force of Savoy and French and mercenary troops is now lined up along the North bank of the River Triebisch currently enshrouded from full sight by a light morning river mist. However, local scouting has reported that the army contains more then a dozen battalions and four regiments of cavalry as well as outnumbering you in cannon, some of which are light and reasonably mobile. Some of the cavalry are reported to be senior French regiments of superior quality.

Deployment 

The red line shows your deployment limit and the map gives some idea of the size of standard units, please allow a bit more space for large units and less for small units.

General von Kotztoter’s brigade must be deployed in 4 out of the 5 locations in Area C  and are alert and ready for battle. If you choose to defend the bridge itself then you can have a barricade across (at the red line) which counts as heavy cover (as the rest of the BUA). Note that the two redoubts only have frontage for 2 bases each so part of a unit will be exposed, but a 3-base unit will have more than half in heavy cover.

Colonel Von Muddel’s brigade is initially the camp guard so must start deployed in Area A. It can’t move on Move One.

The remainder of your force can be deployed in both Areas A and B. The infantry and cavalry are resting at arms but are not yet prepared to move. So they may not move in Move One. The artillery are under orders not to fire into the river area unless it is crossed by the enemy or they, or adjacent units, come under fire.

These two photos show general views of the opening dispositions.

About half of Ken's Imperial army is considered out of sight and only represented on the table by numbered counters at this stage

Ken, as General von Erickson did not have a lot of choices but made sure he did not neglect the open right flank. He held back infantry battalions from the front line fortifications at first, fearing heavy enemy fire. Guy's plan, with the Duc de Deuxchevaux, was to concentrate as much as possible of the infantry on his right flank to press hard against the Imperial left and the gap between the hills. Meanwhile Kevin's force, under the Chevalier de Neuvalee, pressed forward to distract as many enemy as possible then sweep into the flank with the heavy cavalry brigade. Guy was adamant that he as not going to waste resources attacking the town or the redoubts.

And here are some close ups

The Imperial right flank, facing East. These infantry battalions are by Fife and Drum/Crann Tara from Ken's' collection. Austrian style dragoons are old RSM figures I bought at a Bring and Buy many years ago, and equipped with Reikland flags

Legion de la Morliere provides the French "surprise" left hook. All Crann Tara figures apart from the fictitious light artillery converted from some spare Foundry Russian "characters". The Legion's first appearance on a wargames table so anything can happen!

Legion de Lauzun, including a galloper gun, backed up by three regiments of heavy cavalry, ready themselves to join the left hook and thrust into the heart of the Imperial defences.

Eight and a half battalions and three batteries comprise the French main attack on their right

In the distance the Savoy attack has got under way, crossing the river with a double move. Canister from two batteries has caused the red uniformed Grenzers to retreat from their redoubt back to the main position.

Two pictures of intense concentration by the players as the French/Savoy attack makes good progress

In the foreground the Morliere Legion also got a double move to cross the river so Ken is having to reform his line to cover the gap 

Guy's second brigade is changing into lines as they march up the road towards the gap in the hills, led by the Battenburg Regiment, and some of his artillery limber up to join the advance

Meanwhile General von Kotztoter got 6 on his Performance die and, being a Dashing commander of light troops, urged the Le Noble Light infantry out of their redoubt to harass the Savoy 1/3 Regt a Pied who were evidently not budging. Pils -Holstein mercenary heavy battery ex Phil Olley's collection, Front Rank figures; and some very old Hinchliffe Napoleonic limber horses with an Old Glory civilian driver

The Duc de Deuxchevaux encourages Baron Joubarbe to get his infantry round the flank of the entrenchment.......

......but opposite them Ken gets his Hessian brigade well placed, with support from heavy artillery and battalion guns

Moving on a bit  this photo shows that the lead Savoy battalion managed to form a line and got engaged in a fire fight with the Hessians.

1/1 Savoy Infanterie a Pied has forced the Le Noble Jagers to withdraw from the wood but in the distance its sister a battalion has been routed by fire from the entrenchment

This general view shows that all the Imperial battalions have now been revealed and are manning the defences where possible. The cavalry are shaping up for a scrap.

Imperial light troops have hurried back through the gap to reform but hard on their heels Guy decided he wanted 1/Battenburg to wheel and take the enemy battery in the flank 

Here is another view. The Salasund Militia have realised the threat to the camp and Colonel von Muddel orders both battalions to move forward. The Jagers try to recover but being "inferior" can't seem to get far enough away (60cm) from Guy's advance

The Erbprinz Grenadiers in Spittelwitz were always "out of command" and Ken retreated them back from the bridge. Their only moment of fame was to get off some pot shots at the passing French dragoons, but without effect. Much to my surprise Ken did not use their "superior" status, giving better initiative, to do anything else with them at all.

In the foreground the Le Noble Light infantry are making a bee line to enfilade the flank of Savoy's 2nd Brigade, but they are still within canister range of the Pils-Holstein heavy battery

Kevin brings up the cavalry brigade to support the Morliere Dragoons..........

.....under the approving gaze of Guy

And here they are piling in, but those Hussars de Lauzun are right under the guns of Ken's field battery in the corner redoubt on Spittelberg..........

.........The Hussars suffered hits which would be telling in due course but here they are being backed up by the Royal Dragoons  and Horse Grenadiers de Savoy (more below)

A nice shot along the Spittelburg showing two of Ken's beautifully presented blue-coated units

The inferior quality Salasund Militia are all that the Imperial force has left to plug that defile. Will Battenburg turn to face them or charge the Heavy battery on the hill?

This next sequence of 6 photos shows a developing situation on the Imperial open flank which would be instrumental in deciding the game .

General Von Trump leads the St Ignon and Bathiani Dragoons in a charge against the Morliere Dragoons, the latter don't have the necessary half move to counter-charge

Major General von Pannewitz manoeuvres the Grosse Hinton and Ost Kennetten regiments to shape up to the Morliere infantry while under fire from the skirmishing Fusilier battalion and the light artillery

The Grenadiers de la Morliere prepare to charge

The Comte de Morliere and the Chevalier de Neuvalee carefully stay 5cm away to avoid flying lead!

These Grenadiers are only a small unit, but superior quality, against a standard unit of Ken's. The Chevalier did not avoid dicing against stray sword thrusts from the nearby cavalry melee, but survived.

Whatever the outcome for the French the Comte de Lauzun was bringing up his Grenadiers, backed by the Cuirassiers du Roi (Converted Victrix Austrian Napoleonic infantry and Perry plastic French Napoleonic cavalry).

In the centre the Le Noble LI had been forced to flee from artillery fire and unfortunately the hit point lost by the Alte Barnisch infantry tipped them over the edge and all of sudden Ken had a big hole in his line

But it wasn't all one sided as the Hessians and Heavy battery had taken such a toll, over time, on the savoy 1st Brigade that three of its battalions were now on the run.

This overall shot shows an interesting picture of the French cavalry having been repulsed with only Bathiani Dragoons holding the scene of that action, while Morliere Grenadiers and Fusiliers had prevailed over the blue coats; Ost Kennetten retired in good order and Grosse Hinton's men took to their heels.

The Morliere Dragoons are "Done For" (well, it was their first game, what do you expect?) and Lauzun Hussars are retreating with 4 Hits

Despite losses in his main attack the Duc de Deuxchevaux is still making a stern fight. A batalion of Savoy infantry is contesting the earthworks while Battenburg have taken possession of both trenches and the heavy battery

Bathiani bravely charges the Royal Dragoons but we don't rate their chances against "superior" cavalry with 2 supporting units

Despite things going pretty well for them Guy and Kevin still look apprehensive

Now a Battenburg battalion has forced one of Salasund's to break, and flanking fire along the Spittelburg behind the defences finishes off the 4th battalion of Von Canitz's brigade. The retreating St Ignon Dragoons risk losing a Hit point for them running past

A final view: Not surprisingly the Bathiani Dragoons have broken leaving the Reikland Horse Grenadiers as the only cover for the line of communications on this flank. the Arquebusiers d'Argentiere have made it onto the Spittelburg and are likely to cut off Ken's battery there.

Conclusion

We concluded that any more moves of play would just have seen Ken trying to hold on at his left flank while evacuating the camp and trying to cover the withdrawal of the right flank units.  We looked at Army Points lost and this was 2 for the French and 3.5 for the Imperial army. Nowhere near the limit for either but it was 20% French and 50% Imperial so that says something about the state of the armies.
I may have over compensated for the defensive works by giving the French more powerful forces, but all credit to Guy's tactics because if he had dissipated that strength along the front it would have been a different story. Ken did the best he could in the circumstances. Holding back his infantry battalions from the entrenchments proved a good idea, but if it were me I'd have had the second and third line units in march column, ready to speed to fill a gap.  I think not trying to do something with the Erbprinz Grenadiers was a mistake as, used with their Dashing commander, or relying on initiative, they could have distracted some of the enemy cavalry away from his right flank.

I really enjoyed organising this game and the players said they enjoyed it too. Kevin has been turned on to mid-18th century and is now asking about figure manufacturers etc; as if he hadn't enough Napoleonics to paint! 

What about Honours of War?

A wonderful flexible set of rules that have a few things we don't like but nothing we can't master. We used all the downloadable amendments, clarifications and optional rules and adapted a few of our own. We cut down a bit on grazing fire (though little of it in this terrain anyway) and I introduced a six shot artillery ammo limit. I think that is about right even though we did not get enough moves to run out.  We believe that the Hit Points lost for others routing through or past you cannot be justified when they are of lower class, nor does it seem fair to lose the same when friendly troops retreat through you. Maybe some would say it is realistic and at least speeds up the game, but it is a bit soul destroying when a player has a lot at once and no chance of rallying them. I also introduced a block on rallying off if a unit was still under threat from artillery fire - that could be eased by retreating, moving into masking cover, or  the shelter of other units. I think it worked well.

A lot happened in only 5 Moves! And we got a result so they are good if you like using a lot of toys and expect them to go quickly once the action hots up. We used about 700 figures but were limited to the speed of one player at a time, so I'm pretty confident that 1000 figures on a more open battlefield and several gamers playing concurrently would give a result in about 5 or 6 hours.

Thanks once again Keith Flint for a good set of rules and an interesting basic scenario on which to build.
