The vultures were in their nest.

Boom, boom-boom, BOOM, boom.

Craig almost sobbed at the sound. Grenades exploding! Grenades flung into the hangar by the attacking group. Grenades blasting among the mystery planes of the Ogrum!

Boom, boom, boom-boom-boom! Grenades exploding like a chain of giant firecrackers. In the hot darkness Craig caught glimpses of flashes of light as the grenades detonated.

Boom, boom, boom, boom-boom!

The flat sullen thuds echoed up the side of the mountain. From the darkness where the sailors crouched a low cheer arose. The men there in the night knew the meaning of those explosions.

Craig held his breath, waiting. The attack was on. Now, no matter what happened, it was too late to withdraw. Now it was kill or be killed, fight or be struck down, destroy or be destroyed. With the knowledge of the savage sacrifice about to take place within the temple, there was no question of the urge of the men to destroy. The Ogrum were beyond the meaning of mercy. Blast them, mow them down, kill them, destroy them utterly!

Craig waited. Tommy-guns chattered in the darkness. Grenades thundered. Then he saw what he had been waiting for. A tongue of flame licked out of the hangar.

Fire in the nest of the vultures!

The flames grew in violence.
