The news of this feat was received with immense enthusiasm, throughout the principality. Great numbers flocked to Glendower's standard; the bards sung songs of his victory, at every village in Wales; and so formidable did his position become that the Lords of the Marches wrote to the king, saying that the matter had gone altogether beyond them, and that his presence, with an army, was urgently needed.
Even in Ludlow, extra sentries were placed upon the walls, the garrison was kept in a constant state of vigilance, and mounted men were stationed, miles out, to bring in the news of the approach of any hostile force.
"'Tis a thousand pities," Sir Edmund said, when the news of the defeat of the Flemings reached him, "that these fellows did not send news to me, a day or two before they undertook this business; for in that case I would have myself headed a force of a couple of hundred of my best men-at-arms, and joined them at some spot in the mountains; and had we been there, you may be sure that Glendower would never have fought his way out. The Flemings are doubtless stout fighters, as they have proved over and over again, in their own country; but they are all unused to mountain warfare, or to fight with wild men, and were doubtless scared by the shrill cries with which the Welsh always advance to battle. Doubtless, too, these men Glendower keeps with him are his best fighters, and they knew that, if they did not succeed in making their way out, no mercy would be shown to them, seeing that they have shown none themselves. Had the battle been on a plain, I doubt not that the Flemings would have stood against many times the number of Welshmen that Owen had with him; but this hill warfare was altogether strange to them, and of course they had not the habit of quickly rallying, and meeting the attack, that is second nature with our men-at-arms. The affair is serious, and unless the king comes hither with an army, Glendower is likely to have it all his own way on his side of the border; and, ere long, there won't be an Englishman left west of the Severn."
However Henry, when informed of the danger, lost no time in assembling another great army; and in the beginning of June advanced into Wales, and ravaged a wide extent of country, carrying his arms into Cardiganshire, and destroying the Abbey of Strata Florida, one of the most venerable and famous abbeys in Wales. Founded in 1164, it was burnt down in 1294, during the wars of King Edward the First with the Welsh, but was soon rebuilt. Here Llewellyn, in 1237, convened all the chieftains of Wales to take the oath of allegiance. There were two copies of the national records, one of which was kept at this abbey, and the other at that of Conway.
The abbey having fallen, Henry's army met with scarcely any resistance, Glendower knowing that his wild followers were no match for the royal troops. He therefore contented himself with harassing them continually, and the army suffered greatly by this continued annoyance, as well as from fatigue and famine. Thus the king returned across the border without having achieved any success, whatever.
The Lords of the Marches were not now ordered to contribute any troops, but were to hold their castles strongly; lest, when the army was fairly entangled among the mountains, Glendower should make a great incursion into England. The only advantage gained by the English invasion was that the king, by promises of pardon and rewards, drew away a number of the leading men who had hitherto acted with Glendower. Their defection, however, was more than made up by the enthusiasm excited by the spectacle of the second retirement of a great English army, without having effected anything of importance.
So evident was this, that in October Henry again advanced, with the contingents of no fewer than twenty-two counties. The season, however, was already unfavourable for operations and, after enduring great hardships and suffering, the army again fell back, having effected even less than the two which had preceded it.
Things, however, turned out fortunately for Oswald. The army had advanced a week across the border when a messenger arrived at Ludlow, with a letter from London for the king.
"It will be no easy matter to forward it," Sir Edmund said, as the despatch was handed to him. "Indeed, I see not how it is to be done. Beyond the fact that the king intended to march west, I know nothing whatever of his intentions, or of the exact road he was likely to take. His orders were strict, that we were to keep our forces well in hand; and to send the letter forward would need two hundred men, at least, as an escort. It places me in an awkward position, indeed."
"If it so please you, Sir Edmund," said Oswald, who was one of the group standing round, when the messenger handed the letter to Mortimer; "I will endeavour to carry the despatch for you. Methinks that, while fifty men would not succeed in getting through to the army, two might, perchance, manage to do so. I shall, of course, ride first to Shrewsbury, through which the king passed; and so follow up the course he took. There should be no great difficulty in doing that, for the march of so great a body of men must have left many traces behind. They will, doubtless, have harried the country, for some distance each side of the line they followed; and it is not likely that I should meet any of the Welsh, until I was near the army. Then, of course, great caution would have to be used; for it is like enough that there are parties of Glendower's men hanging on its skirts, to cut off stragglers, and plunder any waggons whose horses may have fallen by the way."
