Polybius, The Histories of Polybius, Vol…
“ Why is it then that the Romans conquer? And what is it that brings disaster on those who employ the phalanx?Why the phalanx fails. Why, just because war is full of uncertainties both as to time and place; whereas there is but one time and one kind of ground in which a phalanx can fully work. If, then, there were anything to compel the enemy to accommodate himself to the time and place of the phalanx, when about to fight a general engagement, it would be but natural to expect that those who employed the phalanx would always carry off the victory. ”
