battles between two phalanxes usually took place in open, flat plains where it was easier to advance and stay in formation. rough terrain or hilly regions would have made it difficult to maintain a steady line and would have defeated the purpose of a phalanx. as a result, battles between greek city-states would not take place in just any location, nor would they be limited to sometimes obvious strategic points. rather, many times, the two opposing sides would find the most suitable piece of land where the conflict could be settled. typically, the battle ended with one of the two fighting forces fleeing to safety.
