I have encountered this very recently in my Sweboz campaign. I was pushing my empire east to the black sea and wanted to take the rebel town of Olbia (I think that was the provice) to gain the profitable sea trade there.

I beseiged the town, then the Koinon Hellenon, who I was neutral with and had no real political dealing with at all, attacked my army with a hoard of gold chevroned hoplites forcing me to withdraw.

They then immediately besieged the town and sacked it. I guess they really wanted that sea trade too...
