Here was fought on another summer day, July 21, 1403, the decisive battle between Henry IV and the Percies. Henry had sat but four years upon his troubled throne when these proud nobles of the north, by whose aid he had ousted Richard II, rose against him. Although Richard had been murdered, Edmund Mortimer, the next of blood, was a thorn in Henry's pillow. Mortimer had been taken prisoner by the revolting Welsh leader, Owen Glendower, and Henry, if we may take Shakespeare for our historian, listened coldly and incredulously to Harry Percy's assurances of Mortimer's resistance. In vain did this eloquent Hotspur, Mortimer's brother-in-law, pour forth his impetuous tale--how "on the gentle Severn's sedgy bank, In single opposition, hand to hand, He did confound the best part of an hour In changing hardiment with great Glendower; Three times they breath'd, and three times did they drink, Upon agreement, of swift Severn's flood; Who then, affrighted with their bloody looks, Ran fearfully among the trembling reeds, And hid his crisp head in the hollow bank Blood-stained with those valiant combatants." When the king refused to ransom Mortimer, Hotspur's anger bubbled over: "He said he would not ransom Mortimer, Forbade my tongue to speak of Mortimer, But I will find him when he lies asleep, And in his ear I'll holla 'Mortimer!' Nay, I'll have a starling shall be taught to speak Nothing but 'Mortimer' and give it him." Thus Hotspur, and his father, the Earl of Northumberland, his uncle, the Earl of Worcester, "the irregular and wild Glendower," and the valiant Douglas of Scotland raised their united banners against the usurper. Many Cheshire gentlemen, to their sorrow, joined Hotspur as he marched through their county. He came in sight of Shrewsbury on the evening of July nineteenth. But Henry was there before him; the royal standard floated over the castle; and it was three or four miles to the north of the town that the shock of battle came. Five thousand of the rebels and three thousand of the loyal forces fell. The Earl of Worcester was slain on the field, and "that spirit Percy" himself, "the theme of honour's tongue," he who had ever been "sweet fortune's minion and her pride," perished there in the toils of his "ill-weav'd ambition." The traditional spot where he fell is pointed out, as also the antique oak from whose leafy top Owen Glendower is fabled to have watched, at a safe distance, the fortunes of the fight.
