He stepped out of the air lock, flinging a command to Calhoun to follow.
Calhoun grunted to himself. He opened a cabinet and donned heavy winter garments. Murgatroyd said "Chee!" in alarm when it appeared that Calhoun was going to leave him. Calhoun snapped his fingers and Murgatroyd leaped up into his arms. Calhoun tucked him under his coat and followed Walker down into the snow.
This, undoubtedly, was the next planet out from the colonized Canis III. It would be Canis IV, and a very small excess of carbon dioxide in its atmosphere would keep it warmer—by the greenhouse effect—than its distance from the local sun would otherwise imply. The snow was winter snow only. This was not too cold a base for military operations against the planet next inward toward the sun.
Walker strode ahead toward the rows of spaceship hulls about the singularly spidery grip ship. It occurred to Calhoun that astrogating such a ship would be very much like handling an oversized, open-ended wastebasket. A monstrous overdrive field would be needed, and keeping its metal above brittle-point on any really long space voyage would be difficult indeed. But it was here. It had undoubtedly lifted itself from Phaedra. It had landed itself here, and should be able to land on Canis and then let down after itself the war fleet now clustered about its base. But Calhoun tried to take comfort in the difficulty of traveling really long distances, up in the tens or twenties of light-years, with such a creation. Possibly, just possibly, warfare would still be limited to relatively nearby worlds—
"We thought," rumbled Walker, "that we might excavate shelters here, so we could bring the rest of Phaedra's population here to wait out the war—so they'd be safe if Phaedra's sun blew. But we couldn't feed them all. So we have to blast a reception for ourselves on the world our children have made!"
They came to a ship which was larger than any except the grid ship. Nearby half its hull had been opened and a gigantic tent set up against it. It was a huge machine shop. A spaceship inside was evidently the cruiser of which Walker had spoken. Calhoun could see where ragged old holes had been made in its hull. Men of middle age or older worked upon it with a somehow dogged air. But Walker pointed to another object, almost half the size of the Med ship. Men worked on that, too. It was a missile, not man-carrying, with relatively enormous fuel-capacity for drive-rockets.
"Look that over," commanded Walker. "That's a rocket-missile, a robot fighting machine that we'll start from space with plenty of rocket fuel for maneuvering. It will fight and dodge its way down into the middle of the grid at Canopolis—which our children refuse to use to land their parents. In three days from now we use this to blast that grid and as much of Canopolis as may go with it from the blast of a megaton bomb. Then our grid ship will land and our fleet will follow it down, and we'll be aground on Canis with blast-rifles and flame and more bombs, to fight for our rightful foothold on our children's world!
"When our fighting men are landed, our ships will begin to bring in our wives from Phaedra—if they are still alive—while we fight to make them safe. We'll fight our children as if they were wild beasts—the way they've treated us! We begin this fight in just three days, when that missile is ready and tested. If they kill us—so much the better! But we'll make them do their murder with their hands, with their guns, with the weapons they've doubtless made. But they shall not murder us by disowning us! And if we have to kill them to save our grandchildren—we begin to do so in just three days! Take them that message!"
Calhoun said:
