Studying the situation, Craig could see no way by which he could effect the release of the men. He had a handful of sailors to help him. There were thousands of the Ogrum. The Ogrum had planes and if they did not have firearms, they certainly had other weapons. "Surprise!" Craig thought. "We've got to take them by surprise, divert them long enough to release our men. Then--" He cursed softly. Presuming a sudden surprise attack enabled them to release the prisoners? What would happen then? "They'll hit us with planes!" Craig cursed. "They'll gas us and spray acid on us, and even if we manage to get away from here, they will follow us through the air." His eyes narrowed. "Which means that we have got to blow up their hangar, destroy their planes, first of all. Then--" A plan was maturing in his mind. He slipped out of the temple, watched his chances and darted across the open space when no sentry was near, rejoined Guru. The dawn man was frantic with excitement. "See monster?" he questioned. "There is no monster," Craig said grimly. "Guru, where cave where Ogrum keep riding birds?" To Guru, the planes were merely large birds that the Ogrum rode. Craig was asking the dawn man where the hangar was located. Guru led him around the temple, pointed to a projecting wing. "Birds kept there," he said. The hangar was open. In line with their ignorance of doors, the Ogrum had never devised a method of closing the entrance of the building where they kept--and no doubt built--their planes. An open space leading down to the edge of the bay apparently was the runway where the planes landed. Inside the hangar Craig could glimpse the strange airships of the Ogrum. Except for the regular sentries that circled the whole immense temple, the hangar was unguarded. * * * * * "Twenty men with grenades will hit the hangar first!" Craig thought. "They'll smash the planes and then they will appear to retreat. The Ogrum will follow. Meanwhile across the city, another twenty men will suddenly appear and start firing the thatch huts. The Ogrum will be confused. Before they can organize themselves, I'll take a hundred men and hit the temple. By God, it will work! "Then," Craig thought, "we'll die one at a time as we try to make our getaway. The Ogrum, even without planes, will hunt us through the jungle forever." He paused, seeking a solution to that difficulty. To free the prisoners only to have everybody perish from the relentless attack of the Ogrum would be no gain. "The only way to keep the Ogrum from pursuing us is to destroy them--utterly!" Craig thought grimly. He had no qualms about destroying the Ogrum, if he could. The only problem was how! He had not enough men and not enough strength to meet them in open battle. Yet they had to be destroyed. "Return to others," he told Guru.
