Alvarado and de Tobar soon found themselves detached from their company. Indeed, as the time progressed and the buccaneers began to perceive the situation they put up a more and more stubborn and successful opposition. They rallied in larger parties and offered a stout resistance to the Spanish charges. Disregarding their isolation, the two young officers ran to the fort. Fortunately the way in that direction was not barred. The solitary sentry at the gateway attempted to check them, but they cut him down in an instant. As they mounted the stair they heard, above the shrieks and cries and shots of the tumult that came blowing in the casement with the night wind, the sound of a woman's screams.
"Mercedes!" cried de Tobar. "It is she!"
They bounded up the stairs, overthrowing one or two startled men who would have intercepted them, and darted to the guardroom. They tore the heavy hangings aside and found themselves in a blaze of light in the long apartment. Two men confronted them. Back of the two, against the wall, in a piteous state of disorder and terror, stood the woman they both loved. In front of her, knife in hand, towered the half-breed.
"Treason, treason!" shouted Morgan furiously. "We are betrayed! At them, de Lussan!"
As he spoke the four men crossed swords. De Tobar was not the master of the weapon that the others were. After a few rapid parries and lunges the Frenchman had the measure of his brave young opponent. Then, with a laugh of evil intent, by a clever play he beat down the Spaniard's guard, shattering his weapon, and with a thrust as powerful as it was skilful, he drove the blade up to the hilt in poor de Tobar's bosom. The gallant but unfortunate gentleman dropped his own sword as he fell, and clasped his hands by a convulsive effort around the blade of de Lussan. Such was the violence of his grasp that he fairly hugged the sword to his breast, and when he fell backward upon the point the blade snapped. He was done for.
Morgan and Alvarado, on the other hand, were more equally matched. Neither had gained an advantage, although both fought with energy and fury. Alvarado was silent, but Morgan made the air ring with shouts and cries for his men. As the swords clashed, Carib raised his hand to fling his knife at Alvarado, but, just as the weapon left his fingers, Mercedes threw herself upon him. The whizzing blade went wild. With a savage oath he seized a pistol and ran toward the Spaniard, who was at last getting the better of the Captain. A cry from Mercedes warned Alvarado of this new danger. Disengaging suddenly, he found himself at sword's point with de Lussan, who had withdrawn his broken weapon from de Tobar's body and was menacing him with it. With three opponents before him he backed up against the wall and at last gave tongue.
"To me!" he cried loudly, hoping some of his men were within call. "Alvarado!"
As he spoke Morgan closed with him once more, shouting:
"On him, de Lussan! Let him have it, Black Dog! We've disposed of one!"
As the blades crossed again, the desperate Spaniard, who was a swordsman of swordsmen, put forth all his power. There was a quick interchange of thrust and parry, and the weapon went whirling from the hand of the chief buccaneer. Quick as thought Alvarado shortened his arm and drove home the stroke. Morgan's life trembled in the balance. The maroon, however, who had been seeking a chance to fire, threw himself between the two men and received the force of the thrust full in the heart. His pistol was discharged harmlessly. He fell dead at his master's feet without even a groan. No more would Black Dog watch behind the old man's chair. He had been faithful to his hideous leader and his hideous creed. Before Alvarado could recover his guard, de Lussan struck him with his broken sword. The blow was parried by arm and dagger, but the force of it sent the Spaniard reeling against the wall. At the same instant Morgan seized a pistol and snapped it full in his face. The weapon missed fire, but the buccaneer, clutching the barrel, beat him down with a fierce blow.
