Permissible as it was by the rules of war, says Polybius, to destroy an enemy’s garrisons, cities, or crops, or anything else by which his power might be weakened, it was the part of mere rage and madness to destroy such things as their statues or temples, by which no benefit or injury accrued to one side or the other; nor are allusions to violations of this rule numerous in pre-Christian warfare.[52] The practice of the Romans and Macedonians to meet peaceably together in time of war on the island of Delos, on account of its sanctity as the reputed birthplace of Apollo,[53] has no parallel in the history of war among the nations of Christendom. The most that can be said for the fourteenth century in this respect is that slightly stronger scruples protected churches and monasteries than the lives of women and children. This is implied in Froissart’s account of the storming of Guerrande: ‘Men, women, and children were put to the sword, and fine churches sacrilegiously burnt; at which the Lord Lewis was so much enraged, that he immediately ordered twenty-four of the most active to be hanged on the spot.’

But the slightest embitterment of feeling removed all scruples in favour of sacred buildings. Richard II., having with his army crossed the Tweed, took up his quarters in the beautiful abbey of Melrose; after which the monastery, though spared in all previous wars with Scotland, was burnt, because the English had determined, says Froissart, to ruin everything in Scotland before returning home, in revenge for the recent alliance entered into by that country with France. The abbey of Dunfermline, where the Scotch kings used to be buried, was also burnt in the same campaign; and so it fared with all other parts of Scotland that the English overran; for they ‘spared neither monasteries nor churches, but put all to fire and flame.’

Neither did any greater degree of chivalry display itself in the matter of the modes and weapons of warfare. Although reason can urge no valid objection against the means of destruction resorted to by hostile forces, whether poisoned arrows, explosive bullets, or dynamite, yet certain things have been generally excluded from the category of fair military practices, as for example the poisoning of an enemy’s water. But the warriors of the fourteenth century, even if they stand acquitted of poisoning rivers and wells, had no scruples about poisoning the air: which perhaps is nearly equivalent. The great engines they called Sows or Muttons, like that one, 120 feet wide and 40 feet long, from which Philip von Artefeld and the men of Ghent cast heavy stones, beams of wood, or bars of hot copper into Oudenarde, must have made life inside such a place unpleasant enough; but worse things could be injected than copper bars or missiles of wood. The Duke of Normandy, besieging the English garrison at Thin-l’Evêque, had dead horses and other carrion flung into the castle, to poison the garrison by the smell; and since the air was hot as in midsummer, it is small wonder that the dictates of reason soon triumphed over the spirit of resistance. And at the siege of Grave the chivalry of Brabant made a similar use of carrion to empoison the garrison into a surrender.

Even in weapons different degrees of barbarity are clearly discernible, according as they are intended to effect a disabling wound, or a wound that will cause needless laceration and pain by the difficulty of their removal. A barbed arrow or spear betokens of course the latter object, and it is worth visiting the multi-barbed weapons in Kensington Museum from different parts of the world, to learn to what lengths military ingenuity may go in this direction. The spear heads of the Crusaders were barbed;[54] and so were the arrows used at Crecy and elsewhere, as may be seen on reference to the manuscript pictures, the object being to make it impossible to extract them without laceration of the flesh. The sarbacane or long hollow tube was in use for shooting poisoned arrows at the enemy;[55] and pictures remain of the vials of combustibles that were often attached to the end of arrows and lances.[56]

The above facts clearly show the manner and spirit with which our ancestors waged war in the days of what Hallam calls chivalrous virtue: one of the most stupendous historical impostures that has ever become an accepted article of popular belief. The military usages of the Greeks and Romans were mild and polished, compared to the immeasurable savagery which marked those of the Christians of Froissart’s day. As for the redeeming features, the rare generosity or courtesy to a foe, they might be cited in almost equal abundance from the warfare of the Red Indians; but what sheds a peculiar stain on that of the Chevaliers is the ostentatious connection of religion with the atrocities of those blood-seeking marauders. The Church by a peculiar religious service blessed and sanctified both the knight and his sword; and the most solemn rite of the Christian faith was profaned to the level of a preliminary of battle. At Easter and Christmas, the great religious festivals of a professedly peace-loving worship, the Psalm that was deemed most appropriate to be sung in the chapels of the Pope and the King of France was that beginning, ‘Benedictus Dominus Deus meus, qui docet manus meas ad bellum et digitos meos ad prœlia.’

It was a curious feature of this religion of war that, when Edward III.’s forces invaded France, so strict was the superstition that led them to observe the fast of Lent, that among other things conveyed into the country were vessels and boats of leather wherewith to obtain supplies of fish from the lakes and ponds of the enemy.

It is indeed passing strange that Christianity, which could command so strict an observance of its ordinances as is implied in the transport of boats to catch fish for Lent, should have been powerless to place any check whatever on the ferocious militarism of the time; and the very little that was ever done by the Church to check or humanise warfare is an eternal reflection on the so-called conversion of Europe to Christianity. Nevertheless the Church, to do her justice, used what influence she possessed on the side of peace in a manner she has long since lost sight of; nor was the Papacy in its most distracted days ever so indifferent to the evils of war as the Protestant Church has been since, and is still. Clement VI. succeeded in making peace between France and England, just as Alexander III. averted a war between the two countries in 1161. Innocent VI. tried to do the same; and Urban V. returned from Rome to Avignon, hoping to effect the same good object. Gregory XI. was keenly distressed at the failure of efforts similar to those of his predecessors. The Popes indeed endeavoured to stop wars, as they endeavoured to stop tournaments, or the use of the crossbow; but they were defeated by the intense barbarism of chivalry; nor can it be laid to the charge of the Church of Rome, as it can to that of the Church of the Reformation, that she ever folded her hands in despairful apathy before a custom she admitted to be evil. The cardinals and archbishops of those days were constantly engaged in pacific, nor always futile, embassies. And the prelates would frequently preach to either side arguments of peace: a fact that contrasts badly with the almost universal silence and impotence of the modern pulpit, either to stay a war or to mitigate its barbarities.

But it is true that they knew equally well how to play on the martial as on the pacific chord in their audiences; for the eloquence of an Archbishop of Toulouse turned sixty towns and castles to the interest and rights of the French king in his quarrel with England; and the preaching of prelates and lawyers in Picardy had a similar effect in other large towns. Nor were the English clergy slower than the French to assert the rights of their king and country, for Simon Tibald, Bishop of London, made several long and fine sermons to demonstrate (as always is demonstrated in such cases) that the King of France had acted most unjustly in renewing the war, and that his conduct was at total variance both with equity and reason.

But these appeals to the judgment of their congregations by the clergy are also a proof that in the fourteenth century the opinion of the people did not count for so little as is often supposed in the making of peace and war. Yet the power of the people in this respect was doubtless as insignificant as it still is in our own days: nothing being more remarkable, even in the free government of modern England, than the influence of the people in theory and their influence in fact on the most important question that regards their destinies.

Nor are the moral causes difficult to trace which in those times made wars break out so frequently and last so long, that those who now read of them can only marvel how civilisation ever emerged at all, even to the imperfect degree to which it is given to us to enjoy it. The love of adventure and the hope of fame were of course among the principal motives. The saying of Adam Smith, that the great secret of education is the direction of personal vanity to proper objects, contains the key to all advance that has ever been made in civilisation, and to every shortcoming. The savagery of the middle ages was due to the direction of personal vanity exclusively into military channels, so that the desire for distinction often displayed itself in forms of perfect absurdity, as in the case of the young English knights who went abroad with one eye veiled, binding themselves by a vow to their ladies neither to see with their eyes nor to reply to anything asked of them till they had signalised themselves by the performance of some wondrous deed in France. The gradual opening up in later days of other paths to distinction than that of arms has very much diminished the danger to the public peace involved in the worthless education of our ancestors.
