In cavalry against cavalry, the moral effect of a mass charging in good order was of the greatest influence. We rarely see two cavalry organizations, neither of which breaks before such reciprocal action. Such action was seen on the Tecinus and at Cannae, engagements cited merely because they are very rare exceptions. And even in these cases there was no shock at full speed, but a halt face to face and then an engagement. The hurricanes of cavalry of those days were poetic figures. They had no reality. In an encounter at full speed, men and horses would be crushed, and neither men nor horses wished such an encounter. The hands of the cavalrymen reined back, the instinct of men and horses was to slacken, to stop, if the enemy himself did not stop, and to make an about if he continued to advance. And if ever they met, the encounter was so weakened by the hands of the men, the rearing of the horses, the swinging of heads, that it was a face to face stop. Some blows were exchanged with the sword or the lance, but the equilibrium was too unstable, mutual support too uncertain for real sword play. Man felt himself too isolated. The moral pressure was too strong. Although not deadly, the combat lasted but a second, precisely because man felt himself, saw himself, alone and surrounded. The first men, who believed themselves no longer supported, could no longer endure uneasiness: they wheeled about and the rest followed. Unless the enemy had also turned, he then pursued at his pleasure until checked by other cavalry, which pursued him in turn. There never was an encounter between cavalry and infantry. The cavalry harassed with its arrows, with the lance perhaps, while passing rapidly, but it never attacked. Close conflict on horseback did not exist. And to be sure, if the horse by adding so much to the mobility of man gave him the means of menacing and charging with swiftness, it permitted him to escape with like rapidity when his menace did not shake the enemy. Man by using the horse, pursuant to his natural inclination and sane reasoning, could do as much damage as possible while risking the least possible. To riders without stirrups or saddle, for whom the throwing of the javelin was a difficult matter (Xenophon), combat was but a succession of reciprocal harassings, demonstrations, menaces, skirmishes with arrows. Each cavalry sought an opportunity to surprise, to intimidate, to avail itself of disorder, and to pursue either the cavalry or the infantry. Then "vae victis;" the sword worked.
