Some of the officers glanced dubiously at the mud in which the horses were standing knee-deep, and they did not budge. Not so Matthew Blackett; with a bound he sprang to the ground, and waded through the mire, half of his long legs submerged, his brethren endeavouring to keep their countenances.

"That's the right way!" sang out the colonel in high commendation, and a little crowd of the men following the example of the young lieutenant, the work of repairing the road was soon in rapid progress, the colonel standing by to direct the operations. Other officers speedily came to help, rather ashamed to think that they had allowed the youngster to set them a lead.

"It's nothing," cried Matthew, cheerfully, as he toiled with a will. "Many's the time I've stood up to my waist in deadly-cold water digging out an old dog otter."

The lad's good-humour and willingness were infectious, and in a remarkably short space of time the track had been repaired. Then, with many a joke at each other's expense, the men remounted and pursued their journey, covered from head to foot with mire, but cheered by the colonel's approving, "It will serve for all the rest of the horse, my lads."

All this time the cavalry were wondering why Tallard took no steps to stop their passage, and none was more surprised than Marlborough himself. He did not at the time know that Tallard had left his centre weak, by sending so many men into the village on the right. Still less, of course, could the Duke know that Tallard was expecting a very easy victory. Be that as it may, the Marshal made no move till Marlborough had got a large part of his men across the stream and had formed his first line.

When Blackett arrived on the scene with his regiment he found that a force of Eugene's cavalry had taken the village of Oberglau, near the spot. A minute later, almost before the colonel had drawn up his men, there was a fierce shout, and there came thundering down upon the village, with almost irresistible shock, a body of the enemy.

"Irishmen, by Jove!" cried a man by Matthew's side. "They'll fight like demons!"

The attack, in truth, came from the Irish Brigade, a doughty body of Irishmen, exiles from their country, in the service of Louis. Before the Englishmen realized the situation the Irishmen had dashed clean through the force occupying Oberglau, and had taken up a position between the men and Eugene.

The confusion was extreme, and the allied troops could scarce be got to face the resistless Irishmen at all. Things looked desperate. The colonel of Blackett's regiment, seeing the state of things at Oberglau, as he toured it, shouted, "Go and tell the Duke, Mr. Blackett!" and away dashed Matthew once more to the General. He was a pretty spectacle, but he did not give the matter a thought, and his news prevented the Duke from paying much heed to the condition of the messenger.

"Lead the way," came the sharp order, and Blackett thundered on in front, the great commander with a body of men hard after him, to find the energetic and plucky colonel fallen badly wounded, and the regiment in difficulties. With a swoop, the reinforcements fell upon the Irishmen, and, almost for the first time, Matthew found himself engaged in a hand-to-hand encounter. He did not know how long the conflict lasted, but presently he found the enemy in full flight, his comrades cheering lustily around him. Marlborough's promptitude had saved the situation.
