New Razmiran would be much, much happier if it had a week to train new troops, serious, what is this "marching all day and night straight past castles which you have the strength to besiege and bypass simultaneously because you don't care about supply lines" nonsense, but with every baronial levy they can pull together, and the support of the Regent of Odranto, New Razmiran has nonetheless assembled about forty-four hundred heavy infantry, mostly their Razmiran veterans, in the usual eight-to-two pike-to-shot (heavy crossbows or longbows) mixture with every cleric of Pharasma in the county drafted to stiffen it with healing, bolstered by their usual outsiders and Razmiran Priests, as well as two thousand militia troops (archers and slingers) that can be expected to rout the first time things go badly, eight hundred aristocratic heavy horse and four hundred light horse scouts and skirmishers, and with this army they intend to hold the ford of Berus against any advance.
Unfortunately, this force has the usual fighting-undead problem - pikes and bows are both effective at finding small vulnerabilities in armor and punching through, when facing armored enemy soldiers. And, really, anything that punches a hole is effective when up against sacks of meat and blood that don't have armor.
They are... not... effective against zombies and skeletons.
The lords of Odranto prepared for this! Their heavy infantry (what they have of it) carries large polearms with an axe-blade on one side (for zombies) and a hammer on the other (for skeletons) and a spike in the middle (for cavalry), which don't have quite the reach of pikes but have enough reach for most purposes. And then they go to war with maces or warhammers as well as (or instead of) swords, for their backup weapons.
The soldiers of New Razmiran... did not. All they have of these fine weapons is that they were fortunate enough to get the lords to provide them. Most of their troops are just going into battle with the usual pikes.
New Razmiran really, really wanted time to rearm, retrain, and get ready for war.
