Another Go At Rules

This week, a return to pondering rules. I’m going to try to fix the issue there was with ‘a second stab at rules’.

Let us again take as our paradigm soldier the Persian infantryman, and give him a 3 in our system.

The Greek hoplite up against him, when 8 ranks deep, should win, so lets give him a 4.

In the centre at Marathon, the Greeks were thin; say 4 ranks deep so pick up a –1.

The Persians get a +1 for being ‘the best’ and another +1 for their initial shield wall.

Thus, in the centre, the Greeks are at 4-1, the Persians at 3 +1 +1 making 3 vs 5. However, the Greeks did charge into contact, so should get at least +1 for doing so, making 4 vs. 5 and, all other things being equal, a slow loss for the Greek centre.

On the wings, the Greeks would be 4 +1 against 3, making 5 vs. 3 and a quicker win for the Greeks.

Two issues arise here. The first is why do the Greeks only get +1 for charging?

Well, the more I’ve read the more doubtful I’ve become that a full-blooded charge could be carried out by a phalanx. This starts to get complex. Some authors would argue that a phalanx was much looser in 490 BC than we assume, but I’m not going there as I don’t see how a bunch of shield and spear armed heavy infantry are going to make progress in a loose formation. The point of a phalanx was that it was rather coherent. This is why police lines tend to hold against demonstrators, after all. So phalanxes cannot just rush at the enemy willy-nilly.

On the other hand, there has to be some bonus for getting to grips. In the case of Marathon, the Greeks would eventually have got disrupted by the Persian archery, so it was worth their while, once in range, closing. So I’ve made a perhaps rash assumption that the +1 for the Persian shields cancels out the impetus from charging / advancing into contact.

Comparing with the first stab at rules, the centre in that came out as 4 vs 4 in the first round, followed by 2 vs 3 for a slow Persian win in the second and subsequent rounds.

This week, we have 4 vs 5 in the first round and 3 vs 4 in the second and subsequent, again making a slow Persian win.

In the wings it should be a slightly faster Greek win.

So does this make any difference?

Well, the Persians still come out a little ahead when they are counted as the paradigm, but not as much as I initially thought. They get a slight advantage on the first round of combat, getting a 5 rather than a 4. This would get cancelled out if I gave the Greeks a +2 for charging, of course, so the two systems would then be equal.

However, there is a ‘but’.

Here, I’ve assumed that the outcomes would be based on the difference of the factors, and that alone. This is the normal route with Polemos rules, at least the ones I’ve written.

If a DBA style combat outcome were used, then the outcomes could be significantly different. As I’m sure most of you know, the DBA style outcome is defined by the ratio of the scored – less than half and less but more than half.

The Polemos system uses a difference of scores – 0, 1, 2, and so on.

In the ratio (DBA style) system, the higher the initial factor, the less likely an opponent is going to double the score. If both sides have a +1, and one rolls a 1, then to double, the opponent only needs to roll 3 or more. If both sides have +4, and one rolls a 1, then the opponent has to roll a 6 to double the score. I’ve not done the numbers and statistics on this, but it appears to me to be slightly non-linear.

The difference (Polemos) system is linear. No matter what the factor, the difference is the same. So a Greek vs. Persian match up at 2 vs. 3 is the same as 3 vs. 4.

So perhaps, while there may be a little bias depending on the paradigm troop type, it is much more limited in the difference system than in the ratio system.

Or, maybe, I’ve got my numbers wrong (again).

Marathon in History

Well, after the deafening silence engendered by the last two weeks worth of blogging (is there anyone out there?) I’ll resort to something a bit more abstract this week.

I’ve now read Peter Krentz’ new book on Marathon, which is pretty good. There are no startlingly new insights; after all, pretty well everything that can be said about Marathon has been said, but it does make an interesting read.

Perhaps the most interesting bit of the book is the first chapter, where Krentz discusses how the battle has been viewed over the centuries. People, from the Athenians, who viewed the battle as a miraculous gift of the gods (especially Pan) to the Persians, for whom it was just a minor set-back in a distant province, have always constructed or reconstructed the meaning of the battle.

Among the most determined and resolute reconstructors were the Victorians, in this, as in so many other things. From Byron to Browning, Marathon was the victory for democracy and freedom. The newly liberated Athenians defeated the invader and the prospective tyrant of Athens.

Freedom and slavery, democracy and tyranny, liberty and civilisation are all still potent political slogans of our age. Yet no-one invokes Marathon today as a symbol of freedom. Why not?

Krentz suggests that the backlash against such ideas started after the Great War. The civilization that started with Athens showed it destructive power, its capacity to commit collective suicide. The courage and virtue that won at Marathon was no match for the technological slaughter which the civilisation that Athens engendered had created.

A few other items assisted in this re-visioning of Marathon. Firstly, Marathon changed nothing. It was a sideshow for the Persians, a punitive expedition that achieved most of its goals. Ten years later, the serious invasion got going and was defeated by both land and sea. Thermopylae, Salamis and Plataea sealed the fate of the Greek world, not Marathon.

Even so, the output of writing about Marathon goes on. Aside from Krentz’ book, I know of at least one more published this year on the battle. The output seems unstoppable, the speculation endless. Amazon lists at least 4 recent books on the subject. Our fascination with this battle, the earliest that we are able to even try to reconstruct, seems endless. Marathon studies are alive and well, in military history if not anywhere else.

Plataea gets a worse press, for some reason, even though it was the decisive battle. Marathon gets strap lines such as ‘civilisations in conflict’, while Plataea gets a few books published a hundred years ago and still in print (or brought back into print). How odd.

Perhaps part of the answer to our interest in Marathon lies in modern geopolitics. As I’ve mentioned before, western civilisations have an uneasy relationship with ‘the east’ and I don’t suppose that the events of the last decade have made that any better. At least at Marathon the “good guys” won, the battle was decisive and everyone neatly went home. Even Datis, the Persian commander, seems to have returned safely to Asia and not been punished. Apart from those unfortunate enough to have been killed in the battle, everyone else got away without damage. Is Marathon then the perfect ‘civilised’ battle?

I suppose the other aspect of Marathon is that it gave the Greeks, Athenians and the late arriving Spartans, confidence that the superpower could be defeated. Perhaps without Marathon Plataea and Salamis couldn’t have happened. Marathon would then be a necessary (but not sufficient) condition for the Greeks winning the Persian wars.

If the Athenians had lost Marathon, what would have happened? Krentz devotes part of his conclusions to such an outcome. If the Athenians had not resisted, history, he claims, would not be too different. The chances are that Athens would simply have continued to develop as it did, with a tyrant imposed by Persia to start with, then as Persian rule lightened, its own mix of tyranny and democracy. Perhaps then, the only real outcome of Marathon was to prolong the Persian wars, and to ensure the destruction of more lives.

A Second Stab at Rules

What happens if we change the basis on which we generate the rules? Following on from last week, where we took the hoplite to be the typical soldier against whom all others are measured, what happens if we change that?

Suppose we take the really typical soldier of the era, the Persian infantryman. A bloke with a bow, spear, maybe a wicker shield, and some sort of sword or long dagger. Again, we shall use Marathon as our yardstick.

Now, in our D6 based rule set, this chap would rate a 3. Opposing him, in the centre at Marathon, are 4 deep hoplites. Our Persian is elite, so gets a +1, and has an initial shield from the front rank, so gets another +1 on the first round of combat (assuming he doesn’t move into contact). So the Persian gets 3 + 1 + 1 = 5 on the first round.

The Greeks lost, so we’ll give them a 2, and then +2 for charging onto contact, giving them a 4 on the first round, and 2 on the second while the Persians get 4. The Greek centre should, on average, lose.

On the wings, the Persians rate 3, while the Greeks are 8 ranks deep, and so get a (say) +1 for that, and +2 for charging into contact. So in total they get 2+1+2 = 5. The Greeks should win on the flanks.

So, comparing this with last week’s numbers, in the centre we get from last week:

Greeks 3 –1 (for being thin) + 2 (for charging) = 4
Persians 2 + 1 (for being the best) + 1 for shields = 4

in the first round, and then

Greeks 3-1 = 2
Persians 2+1 = 3

in the second.

This week, we have

Greeks 2 +2 = 4
Persians 3 + 1 + 1 = 5

in the first round, and

Greeks 2
Persians 3 + 1 = 4

on the second.

What difference does this make?

Well, on the face of it, not much, but I’d be willing to lay a little money (if I were a betting person) that a statistical analysis of these numbers would suggest that the Persians have a bit of an easier time of it if they are the ‘average’ infantryman. That is, if the Persians are normative, they have a slight advantage, while if the Greeks are, they do.

On the wings the story is similar: The Greeks are 3 + 2 = 5 from last week, while the Persians are at 2. This week the Greeks are at 2 + 1 + 2 = 5, while the Persians are at 3. In other words, again, the Persians do slightly better (on average) if we take them to be normative.

In both schemes, the battle should be reproduced, more or less, on average. But the ease of victory, all other things being equal, the side which has been taken to be the norm does slightly better.

There doesn’t seem much to be done about this. As far as I can see, this is an inherent bias in the way the rules are set up. And I suspect that it isn’t just these rules, but pretty well any rule set. The designer, it seems to me, has to take some troop type as the basis type – English billman, Saxon huscarl, Union rifleman, whatever. But doing that, by matching others against this type seems to generate an implicit bias.

It is entirely possible that I’m wrong, here. Please do point it out to me if I am, but at the moment I can’t see it. Of course, there are many other factors apart from the raw numbers which come into play – the tactical situation, numbers of bases in contact, supports and so on, but it does seem to me that if the basis in inherently biased, the overall rules are going to be, however slightly and however much other factors might cover it up.

A First Stab at Some Rules

Lets try to do some serious thinking about rules and mechanics for the Greeks and Persians.

We’ve not got much to go on, but lets try with Marathon. I’ve just got Peter Krentz’ new book on the battle; I’ve not read it, but having it is nearly as good, isn’t it?

We know a few things about the action.

Firstly, the Athenians and Plateans were hoplites – spear, shield, body armour and greaves. Secondly, the Persians were infantry – bow, short spear, sword, quilted armour. We’ll leave aside the mystery of the Persian horse for the moment (at least until I’ve read the book).

We also know that the Greeks had a thin centre and normal depth wings (Herodotus Histories 6:111). The best Persian troops were in the centre. The Greeks broke the Persian wings and the Persians the Greek centre. The Greek wings then turned in and broke the Persian centre. The fighting was lengthy – this was no walk over.

So, how do we develop some rule mechanics for this?

Let’s start with the Greeks. Let a normal (8 rank) hoplite base have a baseline fighting value of 3, assuming we are using a D6 based rule set. This is actually quite an important decision, because it means that everything else is going to be based on the perceived fighting value of hoplites.

Now, it is clear that, in hand-to-hand combat, the hoplites had the upper hand against the Persian infantry (bow, spear, kitchen sink etc – what Phil Sabin calls in Lost Battles “the elusive heavy infantry archer”). So let us give the Persian infantry a basic 2. After all, Marathon is said to be lengthy.

Now what?

Well, the Greeks in the centre were thin, so lets give that a –1, and the Persians in the centre were said to be the best, so lets give the best a +1. So that makes the centre clash a 2 (Greeks) against a 3 (Persians). The wings will be 3 (Greeks) against 2 (Persians). It is also possible that the wing Persians were worse than average, so they could be an additional –1. But this sort of balance looks about right. On average, the Greeks should win on the wings and lose in the centre.

There is also the issue of the Persian shields. Now, the rumour has it that the Persians fought in depth with arrows, with the front bloke with spear and big shield thing, possibly stuck in the ground in front of him. What do we do about this option?

Rather than invent a new troop type, I think a +1 to the Persians with this, in the first round of close combat only, would cover it. Again, I’d guess that the best Persians would have this, so the centre battle becomes 2 against 3 + 1 on the first round.

Now, the other thing is about the shooting. The Persians were archers, and we know that the Greeks advanced rapidly to cross the ‘beaten zone’. There are significant arguments in the literature as to whether this was possible or not. Additionally, I presume that this means that the hoplites hit the Persian lines at a run, as the result of a ‘charge’ in all but name. Persian archery seems, in this instance, to have been fairly ineffective, possibly because the Greeks were armoured with metal.

So, the archery should have maybe a baseline 1. I suspect that as an English person, I have in mind the Hundred Year War archer with his machine gun. Persian bows were a long way from that (unless anyone has any evidence to the contrary?), so lets make them fairly feeble. The Greeks defensive armour would give them say a 3 or 4 against archery, and we can fix the combat results table so that they do not get ‘halt’ outcomes unless it gets really bad. Furthermore, the defensive factor against shooting would not depend significantly on the depth of the formation.

Hitting the Persians at a run should give a positive factor; say +2 in the first round of combat. So now, in the centre, we have the Greeks at 2 + 2, possibly –1 for being shaken, giving 3, while the Persians are at 2 +1 for being ‘the best’ + 1 for the initial shield wall, giving 4. In the second round, the Greeks will be at 2 while the Persians are 2+1. The Persian centre should be able to stand against the Greeks and ultimately, beat them.

On the wings, the Greeks are 3 + 2 for charging, maybe –1 for being shaken, while the Persians are at 2, assuming they have no front shields and are ‘average’ as opposed to ‘poor’. At 2 vs 4 or 5, the Persian wings should crumble quite nicely to the Greeks.

The only other questions are about command and control. The Greek wings were controlled and turned in by their commanders. I wonder how they managed that, and how we are going to make a stab at reproducing it. But that is, I think, for another week.

"From Marathon to Waterloo, in Order Categorical..."

Good old Gilbert and Sullivan, eh?

So, what have I learnt so far, a week into the project.

Firstly, there is a heck of a lot of literature out there.

Secondly, there is very little agreement between scholars over, well, anything, really.

Take the battle of Marathon (490 BC). In spite of the battlefield being located, subject to archaeological investigation and there being an account of the battle in the classical sources, practically everything about it is disputed. Even the facing of the armies.

Why would a professional Persian army fight with their backs to the sea? Yet that is the main weight of scholarly opinion. OK, maybe they didn't expect to lose, but we should give the Persians a bit of credit for some common sense. It also doesn't explain that if the Persian centre was turned in upon by the victorious Greek wings, how the next bit of the fighting took place by the Persian fleet, which was beyond the Persian right. It seems to work better if the Persians arranged themselves between the sea and the foothills - as in Grant's article in Military Modelling. Then they can run away to the fleet, not have to fight their way past victorious Greeks in order to have another fight when boarding their ships.

So in spite of all the literature I've uncovered, there is no real agreement on exactly how Marathon was fought. What, for example, was the Persian cavalry doing? Was it not there? Had it already embarked for the descent on Athens? Had it taken the coast road to Athens to force the Greeks to fight? Was it there but just milled around uselessly while the infantry slugged it out? All of these seem to have been suggested. In wargame rule writer's terms, its is a mess.

And then there is archery. The Persian arrow storm and the Greeks doubling through the 'beaten zone'. All sorts of explanations abound - weak bows, good armour, heavily armed infantrymen who rely on their formation for effect (or at least, keeping safe from those elusive Persian cavalry) running 200 meters to minimise the number of arrows hitting, and so on. Oh dear. Too little evidence and too many overactive imaginations to really make a decision as to what happened.

And yet, as wargamers, we demand modelling of this. Is it any wonder that rules writing is a somewhat thankless task?

Mind you, all this is nothing compared to the controversy over exactly how hoplites fought, but that is for another post.
