Roman General

[cunctator]

A roman general could decide from case to case if he wants tocommand his army from horseback or on foot.

Tacitus mentioned specially that Agricola sent away his horse at mons graupius to encourage the troops and praise his valour. So that was not the normal way he commanded his forces.

Quote: Agricolca chapter 35
"Agricola, fearing that from the enemy’s superiority of force he would be simultaneously attacked in front and on the flanks, widened his ranks, and though his line was likely to be too extended, and several officers advised him to bring up the legions, yet, so sanguine was he, so resolute in meeting danger, he sent away his horse and took his stand on foot before the colours."

I think what we should do is make the imporatant family members with horse and the normal or low generals with ground troops. I saw this is possible on the RTR mod where the barbarian generals weren't all mounted. One of them was in a barbarian warband.
