The story ends with the narrator's faint cry, "France! France!" being heard just before the story abruptly cuts off. This cry, alongside the earlier mention of General Lasalle, implies that the French army, fighting against the Spanish during the Inquisition, has arrived and liberated the narrator.
It's worth noting that the story doesn't explicitly state this, leaving a degree of ambiguity. However, the timing and the narrator's cry strongly suggest that the French army is the force responsible for his rescue.
