by whatever means you were placed in your present position, whether willingly or unwillingly, if there is to be a conflict, retire, I beg you to the rearmost line; it will be more honourable for you to flee from a fellow-citizen than to fight against your country.
But if there is to be peace you will take your place with honour amongst the foremost and play the part of a beneficent mediator in this conference. Demand what is just and you shall receive it, though we should acquiesce even in what is unjust rather than embrue impious hands in one another's blood.”
