One of the last to make his escape was O’Harrall. He had been hard-pressed by Lieutenant Tarwig, who shouted to him to yield; but, springing on a gun and aiming a desperate cut at the lieutenant’s head (fortunately the cut was parried, or it would have finished the gallant officer), the pirate leaped over the bulwarks, and disappeared beneath the dark waters. Mr Tarwig jumped up on the gun, and eagerly looked over the side to ascertain what had become of his late antagonist. He could make out through the gloom several persons swimming away from the ship, but whether or not one of them was O’Harrall, it was impossible to say.

Not a pirate now remained alive on the deck of the Ouzel Galley. A dozen or more had been cut down, and so effectually had the British seamen wielded their cutlasses that every one of them had been killed outright. The marines had followed the boarders, and now began firing away at the pirates in the water; but, the darkness concealing the swimmers, no effective aim could be taken. As the boats on the starboard side could not be lowered while the two ships were close together, and those on the other had gone away under Lieutenant Foley, the pirates could not be pursued, or probably several would have been captured.

Commander Olding, knowing the treachery of which the pirates were capable, at once ordered a search to be made below, in case they might have tried to blow up the ship; he himself hurrying into the cabin, where he thought it possible that the prisoners might still be confined. He soon ascertained that they were not there, but he discovered a door leading to the main hold. Obtaining a light, he, followed by the master and Crowhurst, made his way to the part of the hold which had before served as a refuge to Norah and her friend Ellen.

In the mean time, Norman Foley’s party, with Owen, had pulled for the western side of the lagoon. As soon as the boats reached the beach, the whole of the party leaped on shore, with the exception of a few hands left to guard the boats.

“This way,” cried Owen, dashing forward in the direction of the building which had so long been his prison. His fear was that O’Harrall might have reached the shore, and would carry off Norah. Of one thing he felt nearly sure, that O’Harrall would have imprisoned her and her father there as the most secure place in which he could leave them; still even that was doubtful, and he might have a long search before they could be discovered.

Norman and Gerald did their best to keep the men together, and to follow close at his heels. At any moment they might be attacked by the pirates. They could not tell how many of the outlaws were collected on the island; it was probable, they thought, that there were the crews of other vessels besides O’Harrall’s followers. Firing could be heard from the side of the harbour, and they concluded therefore that fighting was taking place in that direction.

It had not occurred to Owen that the prisoners might have been kept on board the Ouzel Galley, and that after all he might be disappointed by not finding Norah. Dan and Pompey sprang forward to his side, and assisted him in keeping to the right path, with which they were far better acquainted than he was. They had got close to the building, when a voice shouted in Spanish, “Who goes there?” The flash and report of a musket followed; the bullet whistled over their heads.

“Bedad, it’s thim Spanish rascals who had charge of us,” cried Dan. “Faix, but it’s all right, for the captin is sure to be there. Give a cheer, lads, and they will know we are coming.”

The seaman, without stopping to receive the order from their officers, uttered a true British cheer, which had the effect of making the Spanish guard take to their heels; and the next instant Owen, bursting open the outer door, was mounting the ladder which led to the loft, followed by Gerald, Dan, and Pompey, the others pressing after them. Quickly reaching the top, Owen found his hand grasped by that of Captain Tracy. The next moment Norah was in his arms, while the old captain was almost overcome with joy and astonishment at seeing his son. For some seconds their feelings prevented them from uttering a word, when Captain O’Brien, coming forward, exclaimed—

“I am delighted to see you, lad, for we had well-nigh given you up as lost. How have you managed to make your way here? Tell us all about it. From hearing the firing we guessed that the pirates must have been attacked.”
