For the middle ages, consult Froissart. The knights in the Battle of the Thirty were armed for battle on foot which they preferred in a serious affair, that is to say in a restricted space. There was a halt, a rest in the combat, when the two parties became exhausted. The Bretons, at this rest, were twenty-five against thirty. The battle had lasted up to exhaustion without loss by the English! Without Montauban the battle would have been terminated by complete and mutual exhaustion and without further losses. For the greater the fatigue, the less strength remained for piercing the armor. Montauban was at the same time felon and hero; felon because he did a thing not permitted by the code of combat; hero, because, if the Bretons had not ably profited by the disorder, he would have been killed when he entered the English formation alone. At the end of the contest the Bretons had four killed, the English eight. Four of the killed were overcome by their armor. Explain how, under Turenne, men held much longer under fire than to-day. It is perfectly simple. Man is capable of standing before only a certain amount of terror. To-day there must be swallowed in five minutes what took an hour under Turenne. An example will be given. With the present arms, whose usage is generally known, the instruction of the soldier is of little importance. It does not make the soldier. Take as an example the case of the peasants of the Vendee. Their unity and not individual instruction made them soldiers, whose value could not be denied. Such unity was natural in people of the same village of the same commune, led in battle by their own lords, their own priests, etc. The greater the perfection of weapons, the more dreadful becomes modern battle, and discipline becomes more difficult to maintain. The less mobile the troops, the deadlier are battles. Bayonet attacks are not so easily made to-day, and morale consequently is less affected, man fearing man more than death. Astonishing losses seem to have been suffered without breaking by Turenne's armies. Were the casualty reports submitted by the captains of those days correct? Frederick liked to say that three men behind the enemy were worth more than fifty in front of him, for moral effect. The field of action to-day is more extensive than in Frederick's time. Battle is delivered on more accidented terrain, as armies with great mobility do not need any particular terrain to fight on. The nature of ancient arms required close order. Modern arms require open order, and they are at the same time of such terrible power that against them too often discipline is broken. What is the solution? Have your combatants opened out? Have them well acquainted with each other so as to have unity. Have reserves to threaten with, held with an iron hand.
