The Dalmatians are concerned about this large force of men and horses so close to our city. We request you take a long way around, by hugging the coast of north africa. This will take a lot longer for you to reach Greece, but Dalmatia must look after its trade routes.
Im Rome, if you trade with the enemy i shall march 10,000 men up to you and burn your city to the ground
Poznan sent 5,000 Mercenaries total and those could take upwards of year to reach Greece. Also only 15,000 Sardinians were sent, you said that earlier. Also there were not 9,000 Carthaginians, there was like a thousand. They pulled out after the ceasefire and then moved back in a thousand on your call.
You cannot do everything instantaneously. Your general and your cavalry will now take a fair amount of time to reach Greece, several hours in real time.
