(Copied over from Reddit - also my post there)

Yesterday I speculated about the game mechanics surrounding combat. Today we'll take a look at what will likely be the first large war facing anyone playing in Central Italy - the Third Samnite War.

The Third Samnite War started in 298 B.C, 5 years after our game starts. Historically, the war was between Rome and a combined alliance of the Etruscan League, the Samnites, Umbria and the Gallic Senones. We can see from this screenshot that all those factions are already in the game (Senones are the bright green strip along the Adriatic). We can even use these two screenshots to gauge the relative strength of the two sides at the start of the game.

ROME has a total force of 35,000 men, 20 Cities, 4 forts and 2 ports, with further allies of 6,000 men and a minimum of 5 more Cities. (Note that there is a band of Roman territory on the Adriatic Coast containing 4 cities)

THE ALLIES, using the above screenshots, have a combined force of 34,000 men (18,000 EL, 8,000 UMB, 8,000 SAM) with a further unknown number from the Senones, 43 Cities (25 EL, 8 UMB, 10 SAM) with a further unknown Senones (at minimum 4, and there are possibly more Samnite and Umbrian cities that aren’t obvious from the screenshots), 7 Forts and 4 ports.

There are also other factors such as manpower and money that will of course be important. Although it’s not clear from the screenshots, we know that Rome’s manpower is roughly 60,000, as is the Etruscan’s. We can estimate that the Allies manpower pool will come to roughly 100,000-120,000. Note that in the third screenshot above, the Devs have used a console command to give Rome 5,000 $$$ to make some buildings, so we can count that out. But there is this screenshot that better explains the situation (note the date of this one and that of the Etruscan forces is taken on the same date). Rome, in short, has more money than the Etruscan League (not historically accurate, but its all subject to change). Frankly I don’t think they need it.

The matchup is very unbalanced. The only hope the Allies have, if we’re using these current figures, is if they can gather their forces together. This is also true historically, though, and the Roman generals frequently split their legions to cause distractions and keep the Allies’ armies apart over the course of the conflict. Before the battle of Sentinum, the largest and most decisive of the Third Samnite War, the Romans drew the Etruscan portion of the combined army away by ordering reserve legions to raid Clusium and its surrounding towns and farms. They then assaulted the combined Senones and Samnite forces, and after a back-and-forth engagement, the Allies were ground down and routed. Roman losses were around 9,000, the allies lost close to 25,000. Livy, who wasn’t born for another 200-odd years but supposedly used sources from the time, wrote that had the Umbrians and Etruscans been present at the battle, the Romans would have faced disaster. It was only by splitting the allied armies that they were able to achieve victory. The remainder of the war was mostly spent carpet-sieging the Samnite lands, as the Etruscans, Umbrians and Senones all withdrew from hostilities.

So how will this be represented in the game? There is still obviously a lot that we don’t know – how will alliances work, how will wars work (there is no current PDS title that would have 3 out of 4 belligerents withdraw from the result of one battle), and how will aggressive expansion work? The end of the war saw the entire Samnium region become incorporated into the furtive Roman state. (That’s the entire teal nation to the South of Rome in the first image linked, if that’s not obvious). I think that we can expect PDS to start with Samnium and Etruria friendly with each other. They didn’t historically have an alliance until the eve of war, so it wouldn’t be accurate to have them start as such 5 years prior, but they are really the only combined force that has the chance to smother Rome in its cradle, as it were, at least if left up to the AI.

If one were to play as Etruria, however, you can envision it playing out quite differently. Carthage could be a threat or an ally to a player in this situation, but the combined forces of the Italian city states and larger tribal confederations would probably be enough, combined with our human ingenuity, to beat Rome.

In short, Rome is clearly marked to be the preeminent power on the peninsula. The surrounding states are going to have a rough time coming together to stop them. In the wise words of Bobby B, 5 separated armies will almost always lose out to 1 combined army of equal strength.

Please note: I've broadly simplified the history of this to keep it succinct. There was of course more nuance to the situation (Lucania was the original defendent and is also visible on the map, south of Samnium), as there always is with history, but I would say that the starting situation of the game does a good job of mirroring the historical balance of power.

TL;DR: Rome will probably win

PS. I can't say enough times - obviously this is still very early in development and everything from the game is subject to change.

The war started when the Samnites invaded the Lucania and Lucanians asked for the Rome support.
In EU4 terms, it would be a sort of "intervene in war" , more than a true alliance.

In the battle of Sentium, actually the Allies managed to unite their forces, probably up to 58-60.000 men against the 38-40.000 Romans. But Umbrians and Etruscans attacked the fortified Roman camp , while Gauls and Samnites fought the open battle against the legions.
Anyway the left flank drive of the roman army was about to collapse and barely resisted to the assault. On the right, things went better and the Consul managed to encircle the enemy and converge toward the left. As always in the ancient battles, when the almost encircled troops lost their cohesion, the butchery began. (25.000 killed 8000 prisoners )

( In game terms I really hope that tactics + commanders could influence battles more than simple number of forces. )

Rome didn't acquired any land from this war, but was clear that no other nation could stop her in central Italy.

At the beginning of the war Rome also managed a quick alliance with the Picens , for sure to prevent them to join the Allies. If another force would joined the Allies probably the course of history would had been very different. ( But Picens were afraid from the Gauls, therefore not so prone to ally them ).

The Etruscans and Umbrians never did attack the Roman camp, although that was their plan! Deserters informed the Romans beforehand of the Allies' intentions, and Consul Quintus Fabius ordered spare legions to raid around the recently lost town of Clusium. This area, which the Etruscans considered their home, drew the Etruscan portion of the force away and they never made the attack on the Roman camp. Quintus Fabius decided to engage the remaining Senones and Samnites, and yes the left flank under Publius was having a very hard time of it after a chariot charge scattered his infantry. Though they did eventually wear the Samnites out on the right and were able to encircle the remaining forces. I didn't go into the battle so much because it wasn't really necessary to the post, but it's always interesting to talk about.

Though the Romans did actually take real estate following the battle - the next two years were spent in Samnium besieging towns, with Cominium Ocritum probably being the most important to fall in 291 (it was a hillside stronghold that was probably necessary to capture before settling Venusia). The Romans forced the Samnites into an alliance, though we can assume it was more like vassalage with the terms imposed. They used their new found "friendship" to start several colonies on Samnite land, including Venusia which had at least 20,000 males sent. It was considered a militarily important location and those men would be needed for any wars to come! (Lookin' at you, Hannibal.)

Edit* Clarified why Cominium Ocritum was important to capture - strategically important not culturally

After the collapse of the Latine League after the war of 340-338 a.C. , all the Roman treaty of "Alliance" after a war should be considered actually signed with subsidiary state...

This is interesting: in Greece (besides the spartan conquest of the Messenic territory, way before the start date of I:R ) there was almost no territorial conquest, and the Greek cities expanded founding colonies abroad. But for the homeland, all the cities (Athens, Sparta, Thebes) based their strength on the concept of hegemony
The Achaemenid Empire and obviously Alexander did real conquests (the latter just to fall apart after the dead of Alexander himself) but again, way before the 304bc.
Carthage based his expansion on the creation of commercial bases and only with Hamilcar Barca , she started conquering land in Iberia.

Rome pursued a different way , both creating "inland colonies" and granting limited rights (sometime even the citizenship) to the..... "allies".

I'm guessing if all these way of expansion will be present into I:R , perhaps using specific "national ideas" (using an EU4 term)

It definitely is interesting - there's definitely more to the expansion of these states than "this is my city now". I really hope that there is more than just one system for expansion involved. Rome's particular expansion method, at least in Italy proper, was what led to the Social War (91-88BC), which is obviously a huge part of Rome's history in the expansion of Citizenship and I'm intrigued about how PDS will approach it. I wonder if it will be a similar system to the way cultures are promoted in EUIV? It wouldn't be a terrible approach, but seems quite binary.

Either way, I'm very excited for the release of the game. There's so much nuance to the age, and with so much technological, cultural and moral disparity between the various powers at play I'm sure PDS are constantly thinking of the best ways to reflect it properly in-game.
