This is a refight of the Battle of Carrhae 53 BC with Romans after the Marian reforms having been led into the desert where they found a Parthian army ready and waiting for them.
Crassus surveyed the battlefield where a solid line of his tired and thirsty legionaries with only Gallic cavalry in reserve faced a seemingly endless number of horse archers – and behind the horse archers were the waiting Parthian cataphracts! This was going to be difficult!
On the Roman left and centre the legionaries could only withstand the arrow storm for so long, and reading the battlefield as well as their general, they broke and ran for their lives. The Roman legionaries on the right did much better, chasing off the Parthian horse archers only to be faced with a fresh horde of them.
It was only late morning and Crassus found himself with his Gallic cavalry trying to hold his left, nothing of his fleeing troops still fighting in the centre, and his brave legionaries on his right facing yet more horse archers. It was still wall to wall Parthian horse archers with the Parthian cataphracts sipping cool drinks and enjoying the spectacle.
The Roman Gallic cavalry charged bravely but the Parthian horse archers evaded still shooting … and shooting … and shooting until there were few Gauls left and they ceased to exist as a fighting unit. In the centre the Parthian horse archers swung to their left and with a few well placed arrows disordered the Roman legionaries there enough to leave them easy prey to the other Parthian horse archers there.
A whole Roman army was lost (pretty historical!) and the Parthian noble cataphracts congratulated themselves on their hard work and great victory!
A very quick game as the Romans fell apart very quickly with some lucky dice rolls for the Parthians. I wonder if the Romans would have done any better if their Gallic cavalry had been deployed forward on one of their flanks from the beginning as they would do serious harm to light horse archers if they survived the arrows to reach them. That might then force the Parthian noble cataphracts to put away their cool drinks and actually do some fighting!
