Well, I am never in a position to send an army when that mission comes up. but I think it mentions something about meeting your reinforcements in the forest to the northeast of the city. If you just land an army by boat and attack the city you will miss out on the back-up army.
Again, I can't verify this because I am normally being swamped by AS and don't really give a damn about some stupid eleutheroi or opening up another front with a steppe faction.
