The Samnites have an army at Bovianum, their largest city, and another Grumentum, threatening the Lucanians. It was this pressure on the Lucanians that was the cassus belli for the Romans. There is also an Etruscan force in northern Italy. The Romans have a pair of Consular armies based in Rome, each composed of a pair of legions.
The second consular army. Note that both armies are composed only of the legions at this point, and do not have any alae from the Roman allies yet attached. At full strength each should have two, each ala being slightly larger than a legion.
The Lucanians, allied with Rome, also have a small field army.
I'm not keen on the Samnites having an outpost at my doorstep with the city of Volsinii. It's not an objective city, but I feel it's a threat to Rome and will need to be reduced prior to any move on the Etruscan territories to the north. So, I intend to strike quickly and lay siege to the city with one of my Consular armies. I'm also going to raise to alae of cavalry to use for scouting, observation, and raiding.
A overview of territory control at the beginning of the war. Rome and her allies are red, the Samnites and allies are green, and the purple territory belongs to the Greek city states.
I ally with a small Latin tribe in May, giving me continuous territory from Rome in the west to the Adriatic in the east, and cutting Samnite lines of communication between the north and south via the placement of a castra at Hatria. The Samnites take exception to this and advance their most powerful army from Lucania to Hatria, laying siege to the encampment there.
With Volsinii now under siege, I take advantage of the relocation of the main Samnite force to the north. My second Consular army, now active, advances to Bovianum and lays siege to the city, which is the largest source of Samnite victory points. At the same time the Lucanians move to take Grumentum, the doorway to Maleventum, the Samnite capital. With a little luck maybe we can knock the Samnites out of the war quickly!
The Samnites have other plans and the summer is spent in maneuver, raid, and siege. My planned siege of Bovianum has to be aborted as Flavius Maximus' Consular army and the main Samnite field force maneuver around central Italy. By October I have Volsinii, Maleventum, and Grumentum under siege. The Samnites continue to maneuver in Campania and hold Bovianum. Here, I'm moving my a cavalry force to the north to keep an eye on the Etruscans and Senones.
In Grumentum, a Samnite cavalry force attempts a breakout...
...while the main Samnite army attempts to relieve the siege of Maleventum. Neither is successful.
In November both Volsinii and Maleventum fall. The loss of these cities is a blow to the Samnites and a boost to my victory points and national morale! Samnium is split in half and isolated from their Etruscan allies to the north. There's been no significant battle yet in this campaign but I haven't wanted one: I'd rather cripple the Samnite source of future recruits and money, and then engage in battles to destroy their field armies when they're out of refuges. There's no real advantage to the Romans to attacking the Samnite armies yet.
Success in November brings an influx of replacement troops in December.
Winter is harsh in the Appenines. I quarter troops in Maleventum and Perusia. I elect to maintain the siege at Grumentum into January since I'm on the verge of starving the city into surrender. The harsh weather proves to be rough on the Lucanians, who experience some significant attrition and eventually have to lift the siege and withdraw back to Velia to rebuild.
The state of the combatants and objective ownership at the beginning of 297BCE. Samnite National Morale is still high, though combat power is declining and they have taken over twice the casualties as the Romans. The Romans control all of the objectives cities except the Samnite and Etruscan capitals.
