Things started with the rambunctious Irish of Seamus O'Flahrty raiding some of their neighbouring Romano British lands. They had all those cattle and valuables just lying around not secured so Seamus was just making them more secure. It seemed totally unreasonable that the Romano British belatedly decided to send what passed for their military to intervene.
TheRomano British had some elite heavy cavalry and the rest was poorer quality levies.
The cavalry charged Seamus' warband and several rounds of combat ensued before the Romans broke. Their pedyt levies fared even less well quickly broken by the Fianna. In the end some milites Roman cavalry managed to inflict a bit of damage back but Seamus had managed to get his ill gotten plunder off the table gathering maximum points from his first game.
