A sense of something outside their calculations began to pervade them as they stood at fault, unable to understand this lack of life aboard the ship they had invaded. Then, suddenly, the darkness of the night was split by tongues of flame from across the harbour, and with a roar as of thunder a broadside of twenty guns crashed its metal into the flank of the San Felipe.

The surprise–party thus, itself, surprised, filled the night with a screaming babel of imprecations, and turned in frenzy to escape from a vessel that was beginning to founder. In the mad panic of men assailed by forces of destruction which they cannot understand, the Spaniards fought one another to reach the gangways and regain the comparative safety of the shore without thought or care for those who had been wounded by that murderous volley.

The Marquis of Riconete, a tall, gaunt man, strove furiously to rally them.

'Stand firm! In the name of God, stand firm, you dogs!'

His officers plunged this way and that into the fleeing mob, and with blows and oaths succeeded in restoring some measure of order. Whilst the San Felipe was settling down in eight fathoms, the men, ashore and re–formed at last, stood to their arms, waiting. But they no more knew for what they waited than did the Marquis, who was furiously demanding of Heaven and Hell the explanation of happenings so unaccountable.

It was soon afforded. Against the blackness of the night loomed ahead, in deeper blackness, the shape of a great ship that was slowly advancing towards the Dragon's Jaw. The splash of oars and the grating of rowlocks told that she was being warped out of the harbour, and to the straining ears of the Spaniards the creak of blocks and the rattle of spars presently bore the message that she was hoisting sail.

To the Marquis, peering with Don Clemente through the gloom, the riddle was solved. Whilst he had been leading the men of his squadron to seize a ship that he supposed to be full of buccaneers, the buccaneers had stolen across the harbour to take possession of a ship that they knew to be untenanted, and to turn her guns upon the Spaniards in the San Felipe. It was in that same vessel, the Admiral's flagship, the magnificent Maria Gloriosa of forty guns, with a fortune in her hold, that those accursed pirates were now putting to sea under the Admiral's impotent nose.

He said so in bitterness, and in bitterness raged awhile with Don Clemente, until the latter suddenly remembered the guns that Blood had trained upon the passage, guns that would still be emplaced and of a certainty loaded, since they had not been used. Frantically he informed the Admiral of how he might yet turn the tables on the buccaneers, and at the information the Admiral instantly took fire.

'I vow to Heaven,' he cried, 'that those dogs shall not leave San Domingo, though I have to sink my own ship. Ho there! The guns! To the guns!'

He led the way at a run, half a hundred men stumbling after him in the dark towards the channel battery. They reached it just as the Maria Gloriosa was entering the Dragon's Jaw. In less than five minutes she would be within point–blank range. A miss would be impossible at such close quarters, and six guns stood ready trained.
