In the game last year, recounted here, the Romans managed to capture a defensive dyke from the British and the over the winter have built a watchtower and are preparing to reinforce it in order to use it as a base to attack further into the British lands. At the same time, the British warlord, Bagotrix, has gathered some of his fellow kings for an attempt to drive the Romans back over the dyke.
The Roman forces consisted of the garrison at the watchtower -- Legion troops divided into line infantry, slingers, mano-balistae, and sentries as well as 2 scorpio and auxilia archer -- and the reinforcements -- a cavalry force with 3 units of medium cavalry and 2 skirmish units of Numidian light horse and an infantry force of legion and auxilia.
The British have 2 forces consisting of Warbands and skirmishers and one force with cavalry, a chariot unit, medium infantry and wardogs.
The noose tightens around the watch tower.
The British medium infantry press to the front door of the gate as the Legion pushes the warband back.
The Romans have a bit of good luck and defend well against the British cavalry, wiping them out before the warbands arrive.
The game ended with the Roman relief force almost completely wiped out but with the tower still in the Roman hands. The Romans will keep the position but they will be unable to use it to attack further in to British lands in the short term.
There will be more adventures of Bagotrix next year at Cangames, I have more British cavalry on the painting table right now (and a Roman elephant -- but I am not sure if I will use that or not)
