Pushed back yes, but retreating? Not a chance. Enemy archers are proven to be weak against the Aculon soldiers due to the massive iron shields they possess blocking most of the arrows. Though I will admit the chariots are good in this terrain, but we have moved back a bit to a more rocky/hilly area that bowmen, all equipped with recurve bows rain down on the chariots taking out the horse and men riding them. To fend off the 5,000 soldiers and other horse/chariot attacks, enemies troops will meet a wall of metal and spears made by the defensive Aculon phalanxes. Enemies can't get close to us without being poked into swiss cheese. As for troops farther away, bowmen will rain more arrows but with fire tipped arrows. Taking advantage of an unguarded capital, Blue will instead march right behind the Valenian capital to simply burn houses, stores, shipyards, anything that will catch fire. If Valenian falls back to the capital, the defensive Aculon army will push into them, if they don't fall back their capital will burn(probably will burn anyways).
Zoom in the map to see a purple square. that is the main battle area.
