Then came a sullen roar—a burst of silvery smoke—a rush of flying bits of iron and splinters; and as those before the barbican leaped back at the Knight's warning cry, the drawbridge crashed down upon the causeway, its lift-chains torn clean away.

Instantly De Lacy dashed forward with waving axe; and beside him went Sir John de Bury, and at his shoulder were Dauvrey and Old Raynor Royk. And they were none too quick; for already those at the entrance were trying to remove the planks that formed the flooring. But with a cry of "Clare! Clare!" Aymer and the others were upon them and they fled within the walls, swinging the gate shut just as the two Knights flung themselves against it.

"Keep an eye upward lest they loose a turret and destroy the bridge," De Lacy shouted, and fell to work on the gate with his heavy axe, while Dauvrey made haste to prevent the dropping of the portcullis by driving a spike into the grooves in which it worked.

But the gate was made of heavy, seasoned oak, studded thick with iron and bound deep around the edges with well-wrought steel. And though De Lacy's blows thundered upon it until it swayed and rattled on its massive hinges, yet it still stood staunch and firm. Presently he paused, and Giles Dauvrey sprang forward to take his place. But he stayed him.

"It is too strong to waste good time and strength upon," he said. "We must use the powder again."

Twice the flagons spoke without material result; but the third tore the gate from its fastenings, and even before the smoke had risen Sir Aymer de Lacy and Sir John de Bury hurled it back upon its hinges and dashed through—to be brought up short by two men in complete armor, who attacked them furiously.

In the narrow passage, with the walls close on either side and the roof low over head, the fighting was hampered and awkward. De Lacy and De Bury were in each other's way and neither could swing a heavy blow; yet they pressed forward, sword and axe drawing fire as they rasped each other or scraped against the rough stones of the arch.

Meanwhile the men-at-arms led by Raynor Royk had poured across the bridge and were crowding close in the rear.

"Bear aside, my lords!" the veteran shouted high above the din of the clashing steel. "We will sweep the way clean by a rush."

But neither Knight gave heed. Gradually De Lacy was driving his foe before him. Step by step he forced him back, until presently they were free of the wall and into the outer bailey. Then he first noticed that, though his opponent bore no device upon shield or hauberk nor crest upon helm, his armor was scarcely of the sort wont to be worn by retainers or simple men-at-arms; it was far too handsome in its lines and fashion and much too beautifully forged. And as he parried the sword strokes, waiting for an opening when he could end the conflict by a crashing blow, he tried to distinguish the face behind the bars of the visor. At first he had thought it was some retainer masquerading in one of Lord Darby's suits of mail, but the sword play was manifestly that of no common soldier; it was too graceful and too skillful to have been learned amid the turmoil of the camp and battle. And suddenly the great hope came that it was Darby himself—who had eluded the King and, following after, had passed him at Pontefract. Instantly the cool method of his fighting vanished; his fingers took a fresh and tighter grip; his battle-cry "Clare! Clare!" rang out vengefully; and with all the fury of his wrongs and pent-up hate he sprang in close. And as he swept his axe aloft its heavy head caught the other's sword and tore it clean away, sending it far across the bailey where it fell with a clang.
