Rupert gradually reached the spot, and had no difficulty in placing himself vis-a-vis to the French officer; for so terrible was his skill, that others willingly turned aside to attack less dangerous opponents. In a moment the swords crossed!

The light was a strange one, flickering and yet constant, with the thousands of firearms, which kept up an unceasing roar. The swords clashed and ground together, and after a pass or two both men drew back. A bright flash from a musket not a yard away threw a bright though momentary light on their faces.

"Monsieur Dessin!" Rupert exclaimed, in delight.

"What! Is it possible?" the Frenchman exclaimed. "Rupert Holliday!"

At the moment there was a tremendous rush of the British. The French were borne back, and hurled over the edge of the outwork; and before Rupert could avert the blow, the butt end of a musket fell with great force upon his late opponent's head.

Rupert leapt forward, and lifting him in his arms, made his way with him to the rear; for with that last rush the fight was over, and the allies had established themselves in the left demi-bastion of the outwork--an important advantage, but one which had cost them 5000 killed and wounded, of whom 3000 belonged to the English force, whom Marlborough had sent. The fact that more than half of them were hors-de-combat showed how fiercely they had fought.

Owing to the wound of Prince Eugene, the Duke of Marlborough had to direct the operations of the siege as well as to command the army in the field. On the 23rd he followed up the advantage gained on the 20th, by a fresh attack in two columns, each 5000 strong, and headed by 500 English troops. After being three times repulsed, these succeeded in maintaining a lodgment in another outwork; losing, however, 1000 men in the attack, the greater part being destroyed by the explosion of a mine.

Both besiegers and besieged were now becoming straitened for ammunition, for the consumption had been immense. The French generals succeeded in passing a supply into the fortress in a very daring manner.

On the night of the 28th, 2500 horsemen set out from Douai, under the command of the Chevalier de Luxembourg, each having forty pounds of powder in his valise. They arrived at the gate of the walls of circumvallation, when the Dutch sentry cried out:

"Who comes there?"
