“Forward!” cried Roberts; and, with their grip tightening, the little party followed their Captain as he once more edged off to the left, performing his former evolution, and, to his delight, finding that the stone-bestrewn polished bottom never once deepened after the first few steps, which took him waist-deep, and kept about the same level, the result being that the next halt was made where the river was roughest, tossing in waves churned up as it was by the masses of rock in its way, a group lying just below the surface, with the water deepening behind them, so that the party had once more to stand breast-high, but in an eddy, the rocks above taking off the pressure which in the shallows had threatened to sweep them away.

The water was numbing, and the leader felt that their pause before recommencing their efforts must be very short; but he was face to face with the most difficult part of their transit, for it was only too plain that this last portion ran swift and deep, the bold, steady rush suggesting a power which he knew instinctively that he would not be able to stem, and he looked downward now to see what was below in the only too probable event of their being swept away.

As he turned to gaze upward again he caught Bracy’s eyes fixed upon him inquiringly; but he paid no heed, though he did not for the moment read them aright, the idea being that his brother officer was mutely asking him if he thought he could do it.

He grasped Bracy’s meaning the next minute, for he heard that which had reached Bracy’s ears. It was a shout from the woody bank they had left, as if one of the enemy had made a discovery, followed by answering cries, and all knew now that their foes were close upon their track, and that at any moment they might be discovered and fire be opened upon them.

“Forward!” cried Roberts, and once more he set off, to be again agreeably surprised, for the water did not deepen in the least as he moved from out of the eddy, being still about breast-deep, with very little variation, the bottom being swept clear of stones and literally ground smooth by the constant passage over it of the fragments borne down from the glaciers in the north. But before many steps had been taken, and the little chain was extended to its extreme limit, Roberts knew that disaster was imminent. For it was impossible to stand against the dense, heavy rush of water, bear against it as he would.

He shouted back to his companions to bear against the pressure, and strove his best, but all in vain. At one and the same moment the double calamity came: there was a shot from out of the patch of forest they had left, and the leader was lifted from his feet. Then pluck, pluck, pluck, as if mighty hands had seized them, the men in turn were snatched from their positions, and with a scattered fire opened upon them from among the trees, they were being swept rapidly down-stream.

Roberts shouted an order or two, and discipline prevailed for a space, the links of the chain remaining unbroken; but even the greatest training could not hold it together for long at such a time, and the non-swimmers were the first to go under and quit their hold, rolling over with the tremendous rush of the stream, and rising again, to snatch wildly at the nearest object, and in two cases to hamper the unfortunate who was within reach.

Sauve qui peut,” muttered Bracy a’s he glided along, with his sword hanging from his wrist by the knot; but his actions contradicted his thoughts, for instead of trying to save himself he turned to the help of Drummond, to whom one of the men was clinging desperately, and the very next minute he felt a hand clutch at his collar and grip him fast.

The rattle of firing was in his ears, and then the thundering of the water, as he was forced below the surface into the darkness; but he did not lose his presence of mind. He let himself go under, and then, with a few vigorous strokes, rose to the surface, with the man clinging to him behind, and wrenched himself round in his effort to get free. He was only partially successful, though; and, panting heavily, he swam with his burden, just catching sight of Drummond in a similar position to himself, many yards lower down the stream.

“Let go,” he shouted to the man. “Let go, and I’ll save you.”
