the long version

The third installment in the "Prince Roger" series finds Roger and his marooned Bronze Battalion of marines ship wrecked on Marduk. After fighting thousands of barbarians, building deep sea ships never considered by mardukans, and crossing an ocean, the army of human marines and local mardukans have reached the continent with the only space port on the entire planet. Which may or may not be held by pirates. Can Roger, the marines, and their four armed mardukan counter parts take the space port? *shrug
