Eric came charging into the central town, and held it for 10 turns. He also had forces streaming up from the south. I basically just played it cool for a while, slowly encircling his force. After about turn 9, my forces grabbed key spotting positions high up on ridges, and began raining down artillery and assaulting with infantry assisted with tank fire.
Thus, what is of supreme importance in war is to attack the enemy's strategy.
