I had about 700 troops, 1 calvary(general) and the rest being a mix of Armoured hopilites and regular hopilites(im Greek by the way) and the Romans (Julli) had about 2,000 troops which consisted of hastati(sp?) and Principi's(sp?). I put all of my troops in the town square and evened out the troops making walls at every entrance. Somehow i managed to win and kill all of them except for 50, my general cleaning up the mess after my Hopilities repelled the roman troops time and time again.
By the way, i did this on H/H and none of my troops defended. Am i so late with strategy that ive just found this way defending cities or has nobody tried this?
