A coiled piece of cloth, dark and menacing, ran up the mainmast of the schooner, reached the top, and then burst out, streaming at full length in the strong wind, dark as death and heavy with threat. Robert looked up and shuddered violently. Over the schooner floated the black flag, exultant and merciless.
The tarpaulin was lifted and the long bronze gun in the stern was uncovered. Beside her stood the gunners, ready for action. The boatswain's whistle blew and the dark crew stood forth, armed to the teeth, eager for action, and spoil. Carlos, a heavy cutlass in hand, awaited his master's orders. The captain laughed aloud.
"So you see, Peter, what we are!" he exclaimed. "And it's not too late for you to seize a cutlass and have your share. Now, my lads, we'll board her and take her in the good old way."
The mate shouted to the steersman, and the schooner yawed. Robert, filled with horror, scarcely knew what he was doing; in truth, he had no conscious will to do anything, and so he ended by doing nothing. But he heard the fierce low words of the pirates, and he saw them leaning forward, as if making ready to leap on the deck of the stranger and cut down every one of her crew.
Then he looked at the other ship. The old man who had been playing the violin suddenly dropped it and snatched up a musket from behind the coil of rope on which he had been sitting. The dancers ceased to dance, sprang away, and returned in an instant with muskets also. Heavy pistols leaped from the shirts and blouses of the spectators, and up from the inside of the ship poured a swarm of men armed to the teeth. A piece of cloth swiftly climbed the mainmast of the stranger also, reached the top, broke out there triumphantly, and the flag of England, over against the black flag, blew out steady and true in the strong breeze.
"God! A sloop of war!" exclaimed the captain. "About, Carlos! Put her about!"
But the sloop yawed quickly, her portholes opened, bronze muzzles appeared, tampions fell away, and a tremendous voice shouted:
"Fire!"
Robert saw a sheet of flame spring from the side of the sloop, there was a terrific crash, a dizzying column of smoke and the schooner seemed fairly to leap from the water, as the broadside swept her decks and tore her timbers. The surly mate was cut squarely in two by a round shot, men screaming in rage and pain went down and the captain staggered, but recovered himself. Then he shouted to the steersman to put the schooner about and rushing among the sailors he ordered them to another task than that of boarding.
"It was a trick, and it trapped us most damnably!" he cried. "A fool I was! Fools we must all have been to have been caught by it! They lured us on! But now, you rascals, to your work, and it's for your lives! We escape together or we hang together!"
