I am sorry I don't have screen shots, but...

I was fighting the Iberians as the Aedui and I noticed that about 3 of their units contained a single Carthagenian. I think it was thier "squad leader" or whatever he is called. But he had the little white flag with the symbol of Carthage.

I think it might have occured because this battle was to defeat the stragglers from a battle where Carthage sent an army to help and we both fought against the Iberians.

I will take a screenshot if it happens again.

P.S. Carthage did not send an army to help in this battle.
