The Duke's horse had fallen heavily, throwing his rider over his head. Others besides his foes were heading wildly for the spot. All who saw it knew how much hung upon the turn of the next few seconds. First of all came the young stranger, who flung himself from his splendid horse, just as Marlborough rose to his feet, bruised and shaken, but with every faculty alert.

"Mount, sire, mount!" cried the traveller, holding the horse by the head to still his excited plunging. "The enemy are closing round; but only mount, and he will carry you safely. I will stake my last ducat upon it!"

The Duke had hold of the saddle by now; one of his own officers sprang forward to hold the stirrup. Next instant the General was in the saddle; but the head of the Colonel who stood at the stirrup was rolling upon the ground. A cannon ball had carried it off. How the Duke had escaped was a marvel and a mystery.

Excitement and lust of battle had fast hold of Grey Dumaresq and his horse. The gallant animal carried the Duke safely back to his own lines, amid the cheers of his soldiers. The young man swung himself upon the back of the riderless horse belonging to the killed Colonel, and followed him, scarce thinking what he was doing. None forbade him. Many had seen his prompt and timely action; many watched him as the tide of battle raged this way and that, and saw that, whether a trained soldier or not, this young stranger was no novice in the art of war. The Duke himself turned more than once to watch him, as he joined in some headlong charge, and turned and wheeled, or gave thrust or parry with the ease of practice and the skill which only comes through experience. Once in a pause he beckoned the young man to his side, and said,—

"I would speak with you, sir, when I am at leisure. Come to my quarters, wherever they may be, when the battle is over. I have somewhat to say to you."

The young man bowed low, and promised compliance with this request; but it was many long hours before he and the victorious General stood face to face. The battle itself had been won in less than four hours, but the pursuit had been long, lasting far into the night; and the dawn was well-nigh breaking in the eastern sky when Grey received a message that the Duke desired speech of him in the house at Meklert, where he had stopped short, whilst his soldiers continued the pursuit of the flying foe almost up to the walls of Louvain.

Marlborough was sitting at a table, whereon stood the remains of a hasty meal; and from the writing materials before him, it was plain that he had been penning one of those dispatches to his wife without which he could never rest, even after the most arduous day's campaigning. He had changed some of his clothes, and though pale and somewhat jaded, preserved that air of elegance and distinction which was always one of his most marked characteristics. But even without spotless linen and fine array, there was something in the high-bred courtesy of Marlborough's manner, and in the singular beauty of his face and person, which always won the hearts of those about him, and particularly so during those years when the magnificence of his military genius was making him the man of greatest mark in Europe.

He rose as the young stranger was ushered in, and offered his hand with a frank and gracious courtesy free from any alloy of condescension or patronage.

"I wish to thank you in person, sir, for the great service you this day rendered me with such timely promptitude. I have never bestridden a better horse, and owe you much for the loan. I would fain learn the name of the gentleman to whom I am so deeply indebted."

"My name, your Grace, is Grey Dumaresq; and that of my horse, Don Carlos. I thank you for your gracious words. We shall feel honoured for all time in that kind Fortune gave us the chance of rendering you some small aid in a moment of peril. The world would have been terribly the poorer by this day's work, had mischance touched the Duke of Marlborough!"
