The Medoeran General Ghant and his men have been in Ilien for a while - terrorizing the peasants for the most part - but they also have another task; keeping an eye out for any reinforcement headed to Ilien from the Roesone guilds.
Unfortunately for the General and his men the Countess is a wily witch, sending a force of her own to take them in the rear at the most opportune moment - as they get ready to attack the Ilienese that have just crossed the Spider River.
Things don't look good for Ghant. The enemy has more than double his number and a flexible force of infantry, cavalry, shock an missile. So he opts to put the Spider River between his men an this new menace, using his mobile marauders and scouts to keep the enemy at bay while his infantry cross.
He avoids complete annihilation - most of his infantry do get across, but a lot of their gear is left behind on the Ilienese side. The scouts and marauders are badly mauled by crossbow fire - they are simply too few to make an effective rear-guard. In desperation they strike out north, back towards Medoere, their cohesion completely shattered.
Its not all that big a battle or important a victory - but it does wonders for Ilienese morale as they return to their city victorious.
