Battle of Capella IV

The Battle of Capella IV was a battle between the forces of the United Federation of Planets and the Narada, a rogue Romulan mining vessel commanded by Nero, who was seeking vengeance against the Federation and Ambassador Spock after the destruction of Romulus by the explosion of the Hobus star. Two Valdore class warbird were also involved in the battle on Nero´s side.
