The Gun by Philip K. Dick (best ereader for epub .TXT) 📗

And a long way off, a hundred miles from the city, another warning light flashed on, far underground. Automatic relays flew into action. Gears turned, belts whined. On the ground above a section of metal slag slipped back. A ramp appeared.

A moment later a small cart rushed to the surface.

The cart turned toward the city. A second cart appeared behind it. It was loaded with wiring cables. Behind it a third cart came, loaded with telescopic tube sights. And behind came more carts, some with relays, some with firing controls, some with tools and parts, screws and bolts, pins and nuts. The final one contained atomic warheads.

The carts lined up behind the first one, the lead cart. The lead cart started off, across the frozen ground, bumping calmly along, followed by the others. Moving toward the city.

To the damaged gun.
