They Came Again

THEY CAME AGAIN...
Alien packs herded small groups of humans into a holding area near the edge of the ruined city. It was a blasted field of no buildings but much rubble. People stood or sat or lay down where they could. More people were added, and in a few days these survivors comprised a sizeable herd of hundreds. They were dirty and ragged,
some were injured. There was no food or water, and the weather was hot. Children cried, babies wailed, and men cursed. A large number of snarling Aliens encircled the trapped humans and waited.
