And then Merril's voice, calm and reassuring, giving heart to all the untried ones aboard with his steady conning commands.

"Four o'clock jet, easy, hold her. Drivers up one half standard. Steady goes. Meet her. Steady—"

Line astern now, the two ships flashing low across the jagged lunar landscape, and a world in the balance—

An alarm bell ringing suddenly, and my screen showing the fleeting outline of a Russian monitor above, running across our stern. My own voice, sharp with command:

"Gun pointer!"

"Here, sir!"

"Get me that gunboat."

The Hound's turret wound about with agonizing slowness as the monitor reached for the sky, clawing for altitude and safety. And then there came a searing blast of fire and the fragments of the Russian gunboat raining down lazily, seeking their eternal rest in the pumice of Luna's hidden face.

But they had been warned at the UN Base. The monitor had left one dying shriek in the ether, and the waiting garrison had heard. Merril knew it, and so did I. We moved forward calmly, into the jaws of hell.
