In Phil Barker’s book, Armies and Enemies of Imperial Rome, general officers wore a muscled corselet with an attic styled helmet this period; beards came also into fashion.
Out my small excess stock I found three candidates
for the position of general; two Greek Successor generals and one Gallic
Chieftain. The Greeks would need fur trim for the cloak and the height of
plumage atop the helmet should be increased a bit. The horses are fine, but the
saddle cloth could be lengthened.
The helmet for the chieftain would
need to be built up and the trousers trimmed to Roman styled breeches. As he is
the only one with shield, I shall need to trim this a bit to conform with the
style of the time.
The three commands in battle array.
