Gervaise's superior weight saved him from falling, though he staggered back some paces; then his heel caught against a stone, and he fell, dragging Hassan to the ground with him. Tightly clasped in each other's arms, they rolled over and over. Gervaise succeeded at last in getting the upper hand, but as he did so Hassan twisted his right arm free, snatched the dagger from Gervaise's girdle, and struck furiously at him. Gervaise, who had half risen to his knees, was unable to avoid the blow, but threw himself forward, his weight partly pinning the corsair's shoulders to the ground, and the blow passed behind him, inflicting but a slight wound in the back; then, with his right hand, which was now free, he grasped Hassan by the throat with a grip of iron. The pirate struggled convulsively for a moment, then his left hand released his grasp of his opponent's wrist. A minute later Gervaise rose to his feet: the pirate was dead.
