Then it was that the Greeks found out that a square is a poor formation when an enemy is following. For if the wings draw together, either because a road is unusually narrow or because mountains or a bridge make it necessary, it is inevitable that the hoplites should be squeezed out of line and should march with difficulty, inasmuch as they are crowded together and are likewise in confusion; the result is that, being in disorder, they are of little service.
