"I understand, sir."

"The moment we push off, get your head sails aback and put her on the wind so as to get out of our way. I shall fill her off on the other tack and then come round and join you. We will keep together until we see whether she means to fight or run. Remember, the great thing is to knock a spar out of her."

So saying, he leapt on to the deck of the schooner, and Turnbull's voice was at once heard shouting the order, "Haul aft the weather sheets of the jibs;" and in a minute the two vessels were gliding away from each other on opposite tacks. Then the Arrow was brought round and followed the Thames, which was the name of the merchantman. The brigantine was now three quarters of a mile away. Suddenly she was seen to change her course. As she wore round she presented her broadside to the two vessels, and her five guns puffed out together. The reply, both from the merchantman and the Arrow, followed almost simultaneously, and a cheer rang out from both ships as the pirate's bowsprit was seen to snap off.

"Place yourself two or three cables' length from his larboard quarter," Nat shouted.

Turnbull, who had leapt on to the rail to see the result of the broadside, waved his hand.

"Down topsails!" Nat shouted, "she will be handier without them."

In a moment the two great sails came fluttering down. Turnbull followed the example, and the men ran up the ratlines and furled some of the upper sails. Deprived of her head sails, the pirate was unmanageable, and the two vessels speedily ran up and laid themselves a couple of hundred yards from his quarters and opened a steady fire. The pirates endeavoured to drag two of their guns right aft, but the volleys of grape poured into them were too much for them, and although their captain was seen to shoot two of the men, the rest ran forward. The helmsman deserted his now useless post.

"Give her one more broadside," Nat shouted to Turnbull, "and then run in and board."
