Ok I've played on a further four turns. I stopped up here as it'd take 3-4 turns to raze Corinth (manoeuvring), and I didn't want to hand over the turn in the middle of a siege.
Ok so report:
T461:
Manoeuvre around for backstab on Peri.
T462:
Say no to free speech.
Declare on Peri, move in units, declare peace on BK (couldn't get tech, didn't want Vienne):
Take and raze Rhodes (Peri has no port now). Lose a marine @85%.
T463:
Sully wants war vs WK, say no.
Results of Un vote, BK and Sully both defy (otherwise we'd lose the 2xp):
Raze Halicarnassus (a new build in former HRE) for no losses.
Try to bribe Churchill, but he's WHEOOHRN, probably us.
T464:
IT lose the blimp, had it in border city no sight into Greece otherwise.
Raze Mycenae for lose of 1 artillery.
Partisans appear, and in hitting them lose a tank (88%) and leave 1 tank and Infantry exposed. There's a worker under the tank, kill before pressing end turn.
Take and raze Pharsalos, lose 1 tank @88% (seems to be my unlucky number that).
For a few ending shots I've basically done troop numbers:
South is our main stack for Corinth. It is light on artillery but should raze (only 4 infantry in atm).
North-Central is our secondary stack, razing it's way south.
North-East is a small stack of Marines, should handle the 2 Infantry in Ephesus easy.
Our naval stack, one giant clunking fist. I'd consider moving it towards England during the next set. It is useless for Pericles, as it'd have to slog through hostile territory to get anywhere.
And finally the Victory screen:
From this I'd say if we took Pericles out we'd have loads of time to win this one.
