Slitherine

I want to design some scenarios for the early 6th Centaury based on Ian Hughes book “Belisarius, The Last Roan General”. I know form DAG games I played that there are some good images for Ostrogothic cavalry such as those used for the Foederatii Cavalry and Ostrogothic cavalry in the Eastern Foederate Roman list as well as others for Ostrogothic archers. However I have not been able to track these down in the scenario editor. Does anybody know where they might be found please ?

Many thanks
Ian
