A difficult choice in my opinion. There are good arguments to be made that peace and quiet on our northern front could be worth the price (and that many refugees could also have a negative impact on the civil stability there). And we also could use another trading partner and ally near us after losing taratine. On the other hand the slaves are valuable and a sastisfactory victory here could go a longer way to solidify our martial reputation.
I also think that this may also be a good opportunity to slow herodion down a bit.
Mark my words, the Messapii will come for us after they finish with Taras, no matter what we do here today. This just determines whether they have a sizable addition to their population at that time, and one that utterly despises us to boot.
No, the independent Peuketii must by necessity be brought to heel and eliminated as a threat, or the Messapii presented with a similar threat to their own endeavors in recompense for our accepting the danger of their proposal.
I like that Idea so counter offer of 500 Greeks for 500 Barbarous?
Question is can they gather up that many slaves in a reasonable amount of time? I suppose they would have to take them away from their own population .
If they can't, then too bad; we continue on with our planned course of action and sell off the people of Azetion. This counter-offer is meant to make it clear that we're not stupid, to give us an unshakable way to silence those who might protest if we rejected the deal out of hand, and if the Messapii accept it gives us a chance to start making amends with Taras for the betrayal Kerkyra forced us to carry out.
On a different subject, I would propose that if we do still have the Peuketii captives in our hands after this vote, we don't keep any of them on as serfs. Instead, we should take them to the slave markets of Persia, sell them there, and use the funds to buy back as many enslaved Eretrians as we can locate; if we still have money after doing so, we should start buying back other Greeks as well, preferably from cities neutral to the Athenian-Spartan dispute or at a 1:1 ratio of Delians to Peloponnesians if those are available.
Any Greeks we so purchase should receive the same offer I would extend to any Tarasians (Tarassoi? Tarasese?) we ransom back, although obviously with "return to Taras" replaced with "return to your home city/their colonies if the home city was destroyed". The exception is of course any Eretrians we find and free, who would remain as citizens of our polis.
