|Affiliation:||United Federation of Planets|
In early 2373, the planet was attacked by the Klingons during the Federation-Klingon War, breaking the cease fire that was initiated a few weeks earlier. In the ensuing Battle of Ajilon Prime, the Klingon forces were quickly able to capture two settlements in the northern hemisphere, trap over half the colonists on the planet and then advance further.
Reinforcements were dispatched aboard the USS Farragut, but the vessel was destroyed before reaching the planet. The USS Defiant reached the planet two days later, and Klingon forces pulled out following the reinstatement of the ceasefire. (DS9: "Nor the Battle to the Strong")
