Now if William really required Harold to swear to all these things, it must have been simply in order to have an occasion against him. If Harold really swore to all of them, it must have been simply because he felt that he was practically in William's power, without any serious intention of keeping the oath. If Harold took any such oath, he undoubtedly broke it; but we may safely say that any guilt on his part lay wholly in taking the oath, not in breaking it. For he swore to do what he could not do, and what it would have been a crime to do, if he could. If the King himself could not dispose of the crown, still less could the most powerful subject. Harold could at most promise William his "vote and interest," whenever the election came. But no one can believe that even Harold's influence could have obtained the crown for William. His influence lay in his being the embodiment of the national feeling; for him to appear as the supporter of William would have been to lose the crown for himself without gaining it for William. Others in England and in Scandinavia would have been glad of it. And the engagements to surrender Dover castle and the like were simply engagements on the part of an English earl to play the traitor against England. If William really called on Harold to swear to all this, he did so, not with any hope that the oath would be kept, but simply to put his competitor as far as possible in the wrong. But most likely Harold swore only to something much simpler. Next to the universal agreement about the marriage comes the very general agreement that Harold became William's man. In these two statements we have probably the whole truth. In those days men took the obligation of homage upon themselves very easily. Homage was no degradation, even in the highest; a man often did homage to any one from whom he had received any great benefit, and Harold had received a very great benefit from William. Nor did homage to a new lord imply treason to the old one. Harold, delivered by William from Guy's dungeon, would be eager to do for William any act of friendship. The homage would be little more than binding himself in the strongest form so to do. The relation of homage could be made to mean anything or nothing, as might be convenient. The man might often understand it in one sense and the lord in another. If Harold became the man of William, he would look on the act as little more than an expression of good will and gratitude towards his benefactor, his future father-in-law, his commander in the Breton war. He would not look on it as forbidding him to accept the English crown if it were offered to him. Harold, the man of Duke William, might become a king, if he could, just as William, the man of King Philip, might become a king, if he could. As things went in those days, both the homage and the promise of marriage were capable of being looked on very lightly.

But it was not in the temper or in the circumstances of William to put any such easy meaning on either promise. The oath might, if needful, be construed very strictly, and William was disposed to construe it very strictly. Harold had not promised William a crown, which was not his to promise; but he had promised to do that which might be held to forbid him to take a crown which William held to be his own. If the man owed his lord any duty at all, it was surely his duty not to thwart his lord's wishes in such a matter. If therefore, when the vacancy of the throne came, Harold took the crown himself, or even failed to promote William's claim to it, William might argue that he had not rightly discharged the duty of a man to his lord. He could make an appeal to the world against the new king, as a perjured man, who had failed to help his lord in the matter where his lord most needed his help. And, if the oath really had been taken on relics of special holiness, he could further appeal to the religious feelings of the time against the man who had done despite to the saints. If he should be driven to claim the crown by arms, he could give the war the character of a crusade. All this in the end William did, and all this, we may be sure, he looked forward to doing, when he caused Harold to become his man. The mere obligation of homage would, in the skilful hands of William and Lanfranc, be quite enough to work on men's minds, as William wished to work on them. To Harold meanwhile and to those in England who heard the story, the engagement would not seem to carry any of these consequences. The mere homage then, which Harold could hardly refuse, would answer William's purpose nearly as well as any of these fuller obligations which Harold would surely have refused. And when a man older than William engaged to marry William's child- daughter, we must bear in mind the lightness with which such promises were made. William could not seriously expect that this engagement would be kept, if anything should lead Harold to another marriage. The promise was meant simply to add another count to the charges against Harold when the time should come. Yet on this point it is not clear that the oath was broken. Harold undoubtedly married Ealdgyth, daughter of AElfgar and widow of Gruffydd, and not any daughter of William. But in one version Harold is made to say that the daughter of William whom he had engaged to marry was dead. And that one of William's daughters did die very early there seems little doubt.

Whatever William did Lanfranc no doubt at least helped to plan. The Norman duke was subtle, but the Italian churchman was subtler still. In this long series of schemes and negotiations which led to the conquest of England, we are dealing with two of the greatest recorded masters of statecraft. We may call their policy dishonest and immoral, and so it was. But it was hardly more dishonest and immoral than most of the diplomacy of later times. William's object was, without any formal breach of faith on his own part, to entrap Harold into an engagement which might be understood in different senses, and which, in the sense which William chose to put upon it, Harold was sure to break. Two men, themselves of virtuous life, a rigid churchman and a layman of unusual religious strictness, do not scruple to throw temptation in the way of a fellow man in the hope that he will yield to that temptation. They exact a promise, because the promise is likely to be broken, and because its breach would suit their purposes. Through all William's policy a strong regard for formal right as he chose to understand formal right, is not only found in company with much practical wrong, but is made the direct instrument of carrying out that wrong. Never was trap more cunningly laid than that in which William now entangled Harold. Never was greater wrong done without the breach of any formal precept of right. William and Lanfranc broke no oath themselves, and that was enough for them. But it was no sin in their eyes to beguile another into engagements which he would understand in one way and they in another; they even, as their admirers tell the story, beguile him into engagements at once unlawful and impossible, because their interests would be promoted by his breach of those engagements. William, in short, under the spiritual guidance of Lanfranc, made Harold swear because he himself would gain by being able to denounce Harold as perjured.

The moral question need not be further discussed; but we should greatly like to know how far the fact of Harold's oath, whatever its nature, was known in England? On this point we have no trustworthy authority. The English writers say nothing about the whole matter; to the Norman writers this point was of no interest. No one mentions this point, except Harold's romantic biographer at the beginning of the thirteenth century. His statements are of no value, except as showing how long Harold's memory was cherished. According to him, Harold formally laid the matter before the Witan, and they unanimously voted that the oath--more, in his version, than a mere oath of homage--was not binding. It is not likely that such a vote was ever formally passed, but its terms would only express what every Englishman would feel. The oath, whatever its terms, had given William a great advantage; but every Englishman would argue both that the oath, whatever its terms, could not hinder the English nation from offering Harold the crown, and that it could not bind Harold to refuse the crown if it should be so offered.
