Caesar made a landing on Briton with great difficulty, because Commius, whom Caesar had sent ahead about making peace, was captured by the Britons and thrown in chains upon disembarkment from his ship. Regardless, he carried the mandate of Caesar to the Britons.
Salve Commius. When Caesar and his army overcome the barbarians in this avoidable fight, the Britons will release you from your chains.
The Britons approached Caesar, seeking peace after their defeat.
Your strength has bested us in battle. We are returning your delegate.
Caesar requires more than that in Briton's imprudent and unnecessary battle. Had you had you heeded the original terms you would've lost no men. Send the Romans hostages, and Caesar will acknowledge peace.
Ships, horses, and crops are failing to the Romans...
The chieftains had a meeting. They decided not to keep honorable to peace with Caesar.
We don't have to stay peaceful...
They don't have much of their baggage...
Let's depart from our camps, and begin secretly leading our own from the fields.
The Britons have many reasons to believe they could fight the Romans. Caesar does not know what plans they may be creating, but the Britons are not to be trusted. Roman honor will keep Romans peaceful, but the legions must take measures to defend against a potential threat.
This will make the Britons appear as a very difficult power for the Romans to overcome.
