On this occasion the invader was Henry IV of England, the father of the other prodigal, whose object is somewhat perplexing, and differs much from the usual raid to which the Scots were so well accustomed. So far as appears from all the authorities, his invasion was a sort of promenade of defiance or bravado, though it seems unlike the character of that astute prince to have undertaken so gratuitous a demonstration. He penetrated as far as Leith, and lay there for some time threatening, or appearing to threaten, Edinburgh Castle; but all that he seems to have done was to make proclamation by his knights and heralds in every town they passed through, of the old, always renewed, claim of allegiance to the English crown which every generation of Scots had so strenuously and passionately resisted. The fact that he was allowed to penetrate so far unmolested is as remarkable as that the invasion was an entirely peaceful one and harmed nobody. When Henry pitched his camp at Leith, Albany was within reach with what is called a great army, but did not advance a step to meet the invader—in face of whom, however, young David of Rothesay, and with him many potent personages, retired into Edinburgh Castle with every appearance of expecting a siege there. But when no sign of any such intention appeared or warlike movement of any kind, nothing but the gleam of Henry's spears, stationary day by day in the same place, and a strange tranquillity, which must have encouraged every kind of wondering rumour and alarm, the young Prince launched forth a challenge to the English king and host to meet him in person with two or three hundred knights on each side, and so to settle the question between them and save the spilling of Christian blood. Henry, it is said, replied with something of the sarcasm of a grave and middle-aged man to the hasty youth, regretting that Prince David should consider noble blood as less than Christian since he desired the effusion of one and not the other. The position of the young man shut up within the walls of the fortress in enforced inactivity while the hated Leopards of England fluttered in the fresh breezes from the Firth, and Henry's multitudinous tents shone in the northern sun—an army too great to be encountered by his garrison and noble attendants alone—while dark treason and evil intent in the person of Albany kept the army of Scotland inactive though within reach, was one to justify any such outbreak of impatience. David must have felt that should the invader press, there was little help to be expected from his uncle, and that he and his faction would look on not without pleasure to see the castle fall and the heir of Scotland taken or slain. But King Henry's object or meaning is more difficult to divine. Save for his proclamations, and the quite futile summons to King Robert to do homage, he seems to have attempted nothing against the country through which he was thus permitted to march unmolested. The little party of knights with their attendant squires and heralds riding to every market-cross upon the way, proclaiming to the astonished burghers or angry village folk the invader's manifesto, scarcely staying long enough to hear the fierce murmurs that arose—a passing pageant, a momentary excitement and no more—was a sort of defiant embassage which might have pleased the fancy of a young adventurer, but scarcely of a king so wary and experienced; and his own stay in the midst of the startled country is still more inexplicable. When the monks of Holyrood sent a mission to him to beg his protection, lying undefended as they did in the plain, his answer to them was curiously apologetic. "Far be it from me," he said, "to be so inhuman as to harm any holy house, especially Holyrood in which my father found a safe refuge.... I am myself half Scotch by the blood of the Comyns," added the invader. The account which Boece gives of the expedition altogether is amusing, and strictly in accord with all that is said by other historians, though they may not take the same amiable view. I quote from the quaint translation of Bellenden.
"A schort time efter King Harry came in Scotland with an army. Howbeit he did small injury to the people thairof, for he desirit nowt but his banner to be erected on their walls. Alwayis he was ane plesand enneme, and did gret humaniteis to the people in all places of Scotland where he was lodgit. Finally he showed to the lords of Scotland that he come in their rialm more by counsel of his nobles than ony hatred that he bore to Scottes. Soon efter he returnit without any further injure in England."
It is very seldom that a Scotch historian is able to designate an English invader as "a pleasant enemy," and whether there was some scheme which came to nothing under this remarkable and harmless raid, or whether it was only the carrying out of Henry's own policy "to busy giddy minds with foreign quarrels"
"Lest rest and lying still might make them look
Too near unto my state,"
it is difficult to say. The nobles pent up in Edinburgh Castle with the hot-headed young Prince at their head did not know what to make of the pleasant enemy. The alarm he had caused, compelling their own withdrawal into the stronghold, wrath at the mere sight of him there in the heart of Scotland, the humiliating inaction in which they were kept by a foe which neither attacked nor withdrew, must have so chafed the Prince and his companions that the challenge thrown forth like a bugle from the heights to break this oppressive silence and bring about the lingering crisis one way or another must have been a relief to their excitement if nothing else. One of the bewildered reasons alleged for the invasion is that young David had written letters to France in which he called Bolingbroke a traitor—letters which had fallen into Henry's hands; but this is as unlikely to have brought about the invasion as any other frivolous cause, though no doubt it might make the young Prince still more eager to take upon himself the settling of the quarrel. We have no reason to suppose that any foreboding of his fate had crossed the mind of the youth at this period of his career, yet to watch the army of England lying below, and to know his uncle Albany close at hand, and to feel himself incapable—with nothing but a limited garrison at his command and no doubt the wise Douglas and the other great noblemen holding him back—of meeting the invader except by some such fantastic chivalrous expedient, must have been hard enough.
And how strange is the scene, little in accordance with the habits and traditions of either country: the English camp all quiet below, as if on a holiday expedition, the Scots looking on in uneasy expectation, not knowing what the next moment might bring. The excitement must have grown greater from day to day within and without, while all the inhabitants, both citizens and garrison, kept anxious watch to detect the first sign of the enemy's advance. Henry, we are told, was called away to oppose a rising in Wales; not indeed that rising which we all know so well in which Prince Hal, more fortunate than his brother prodigal, had the means of showing what was in him; but even the suggestion approaches once more strangely and suggestively the names of the two heirs whose fate was so different—the one almost within sight of a miserable ending, the other with glory
