Space Prison by Tom Godwin

AFTER TWO CENTURIES.... "The sound came swiftly nearer, rising in pitch and swelling in volume. Then it broke through the clouds, tall and black and beautifully deadly--the Gern battle cruiser, come to seek them out and destroy them. Humbolt dropped inside the stockade, exulting. For two hundred years his people had been waiting for the chance to fight the mighty Gern Empire ... with bows and arrows against blasters and bombs!"

"Space Prison" is an epic tale of survival. After war between Humans and Gerns erupted, a human interstellar ship with eight thousand colonists is captured. Half of the group is left to die on a hellish planet called Ragnarok -- a planet of high gravity, impossible temperature extremes, murderous wildlife, and no usable resources. "Space Prison" covers the two-century history of this stranded colony, and describes its survival and how it eventually adapts and thrives.
