At this moment there was a slight shock, as the lugger came in contact with the ship.

"Come on, lads," O'Grady said, as he set the example of clambering down onto the deck of the lugger. He was followed by his men, the first mate and six sailors also springing on board. The hatches were first put on to keep the remnant of the crew below. The sailors knotted the halliards of the main-sail, the soldiers tailed on to the rope, and the sail was rapidly run up. The mate put two of his men at the tiller, and the soldiers ran to the guns, which were already loaded.

"Haul that sheet to windward," the mate shouted, and the four sailors, aided by some of the soldiers, did so. Her head soon payed off, and amid a cheer from the officers on deck the lugger swept round. She mounted twelve guns. O'Grady divided the officers and non-commissioned officers among them, himself taking charge of a long pivot-gun in the bow.

"Take stiddy aim, boys, and fire as your guns bear on her; you ought not to throw away a shot at this distance."

As the lugger came out from behind the Sea-horse, gun after gun was fired, and the white splinters on the side of the brig showed that most, if not all, of the shots had taken effect. O'Grady's gun was the last to speak out, and the shot struck the brig just above the water-line.

"Take her round," he shouted to the mate; "give the boys on the other side a chance." The lugger put about and her starboard guns poured in their contents.

"That is the way," he shouted, as he laboured away with the men with him to load the pivot-gun again; "we will give him two or three more rounds, and then we will get alongside and ask for his health."

The brig, however, showed no inclination to await the attack. Some shots had been hastily fired when the lugger's first gun told them that she was now an enemy, and she at once put down her helm and made off before the wind, which was now very light.

"Load your guns and then out with the oars," Captain O'Grady shouted. "Be jabers, we will have that fellow. Let no man attend to the Sea-horse; it's from me that you are to take your orders. Besides," he said to Terence, "there is no signal-book on board, and they may hoist as many flags as they like."

The twelve sweeps on board the lugger were at once got out, and each manned by three soldiers. O'Grady himself continued to direct the fire of the pivot-gun, and sent shot after shot into the brig's stern. The latter had but some four hundred yards' start, and although she also hurriedly got out some sweeps, the lugger gained upon her. Her crew clustered on their taffrail, and kept up a musketry fire upon the party working the pivot-gun. Two of these had been killed and four wounded, when O'Grady said to the others:
