Skirmish at Capella

The Skirmish at Capella was a military conflict between the Klingon Empire and the Ten Tribes of Capella.

History and specifics
On the planet Capella IV, a Klingon operative named Kras was sent by a local Klingon military commander to secure mining rights for topaline on the world. Kras proved to be treacherous, manipulating tensions between factions within the Ten Tribes, and, in the presence of Federation envoys, was killed by Maab, a local leader. 

The news of the death of Kras caused anger among his superiors, who had been working to distract the defenses of Starfleet personnel present at the world. The aggrieved local commander ordered an attack on the Capellan tribes, who were defended by a Starfleet landing party detailed to secure the Federation mining claim on the world.
