First off, how is it that they have no iron in that town? I mean, that's great and all because they can't upgrade those units as long as they have no iron there.
Second, Poly should move past that town and pillage the roads to it to prevent iron from ever getting there. Also, since that town has walls and a barracks, Poly will have a VERY hard time taking it, whereas other towns will fall much easier.
Third, if we declare war in the game, we won't be able to spy on their cities any longer. This may be the best assistance we can give to APO, so let's not rush into it foolishly. I suggest we march our units into position for an attack, but do not declare war until such time as we can do some real damage to GCA.
Finally, did you happen to scroll over to see exactly how many units (and what types) are in the town of Algalord? We know there are at least 14, but how many more could there be?
