'Duel' by Terry Nation

A squad of Federation pursuit ships captained by Travis pins down the Liberator, and a stand-off ensues. But then Blake and Travis disappear, reappearing on a nearby planet. They meet Sinofar the Guardian and Giroc the Keeper, two remaining spirits of the planet’s inhabitants, who destroyed themselves in violent war many years ago, and who know plan to teach the two captains a valuable lesson by forcing them to resolve their differences in a duel. To make this lesson particularly effective, the two aliens allow each combatant to have one companion: Blake is given Jenna, while Travis is given a Muto, one of the blood-drinking genetically-augmented slaves of the Federation. Armed with his wits, and using natural materials to construct weapons, Blake is able to beat Travis, but at the last moment, he refuses to kill his nemesis. Satisfied that Blake has learned something from the combat, Sinofar grants Blake the chance to leave the planet, keeping Travis behind to allow them a head start in their pursuit.
