Hey gbno1fan – let me say that I officially have a "strong opposition" to having a Hoplite defend Eureka Stockade.

Besides, Classical Hero had to leave before we really discussed the situation. I'm optimistic that he would have changed his mind.
I agree with you that leaving the Knight till reinforcements arrive is prudent… but I'd be really supprised if the Nuts stabbed us in the back.
Not because I just trust them… but because they can't be sure KISS will attack MIA. After all, Dnuts are by far the weakest nation now (excepting the soon-to-be RIP TNT) and Dnuts have to be VERY worried that KISS will just make peace with MIA, and continue their conquest on the Battle Isle.
I believe this is the reason they have been as accepting of our settlement on their land in the first place – they can't afford to risk a war with us… they don't have the forces.
So I trust the Nutters right now… because backstabbing us would likely be suicide for them.
Finally – I like your thinking on the Defense plan, but I think you've calling for WAY too many forces in the south.
I can see keeping a modest contingent at Ithaca to guard against a surprise NUT attack. But otherwise – up North is where all the action is going to be.
I'll be amazed if KISS tries a seaborne invasion of our core – but if they do, it'll either come down our coast and we'll see it coming miles away – or if they try another route, it'll only take 2-3 Caravels to serve as effective warning scouts… giving us plenty of time to reposition forces.
In my opinion, we are MUCH better off putting our shields and gold into Knights/Cavalry/Artillery to form a welcoming committee to meet KISS on the beaches… and then march north and give KISS a big "thank-you-for-visiting party."
Hopefully we'll be highly railroaded by the time the war break out anyway and can reposition forces quickly if necessary.
In the meantime – it is in our best interest to take the fight to KISS. We have a tremendous amount of infrastructure, and we really don't want any scorched-earth warfare taking place in our lands.
We're going to have a LOT more cavalry than KISS can conceivable have… I say we use it to our advantage and expand the mighty Greek Empire!!
(And don't forget, KISS kindly cut down a couple jungle paths for us… allowing our cavalry to strike their towns on turn 1 of a war… with no chance for them to counter-attack!)
EDIT: oh - and can I suggest the idea of moving our MedInf "Butes" down into Ithaca? Seems like he'd be more useful there than in that town 3 north (name excapes me at the moment)
