"Out of sight, everybody!" Craig shouted. The sailors slipped hastily to cover. Craig joined them. Guru had already leaped back into the mouth of his cave.

"What are those devils after this time?" Michaelson asked.

A second later, they had the answer.

Rolling across the swamps came the sound of a thunderous anti-aircraft barrage from the Idaho.

The Ogrum were moving in to attack the warship, to deliver the last smashing blow against the stranded battle wagon! Like vultures circling a dying animal, they wheeled over the Idaho.

"Come on!" Craig said. "I don't know what we can do to help but we will go and see."

As he hurried out of the ravine he saw Guru hastily helping his mate carry the child to a higher, safer cave. Guru was hiding. The dawn man might face a flying dragon, but the Ogrum were too much for him. Craig did not blame him for hiding. He led his group hastily toward his boat.

Before they reached the place where they had left the small boat a crash sounded behind them. Turning, they jerked up their guns. In this jungle wilderness, anything might be attacking them. When they saw what was following them, they dropped the muzzles of the weapons.

It was Guru. Waving his club, he had come to join them. He was chattering excitedly.

"He says he has put his wife and little one where they will be safe," Michaelson translated. "He wants to know if we are going to fight the Ogrum."
