Managed two games with Stephen firstly fielding an Arab Conquest horde (a whopping 27 elements) and then a later Sassanid army.
Against the Arabs the compact Byzantines (22 elements of which 8 are light types) struggled as tough to deal with a wall of heavy infantry and needing to inflict 27 victory points is a big ask.
They did manage to inflict 17 but had succumbed to own losses at that stage.
Second game against Sassanids with Stephen using pseudo figures (but is contemplating painting up a army which is very doable in LADG).
This was a much more even affair as Persians also 22 elements and Byzantines able to manouvre a tad better as not wall to wall enemy.
Byzantine mounted do not shoot as well (counting as mediocre) as Persian types but do have impact so fairly even match up overall.
The shooting hits from Persian bows did tell in the end however as enough to tip Byzantines over their tipping point before suffering same, but another close game.
