President. They were escorted through Federation space by the USS Enterprise, under the command of Captain James T. Kirk. An admirer of Kirk, Chang met him when Chang and his entourage were invited aboard the Enterprise for dinner. The Klingon general greeted Kirk as a "fellow warrior". During the dinner, Chang inadvertently paraphrased Adolf Hitler with a comment about "breathing room", which Kirk noted. After the Klingons returned to their ship, the conspirators struck. The modified Bird of Prey, invisible and near the Enterprise, attacked Gorkon's ship and made this look like the Federation ship was responsible. Then, two Starfleet conspirators beamed aboard Gorkon's ship, mortally wounded the Chancellor and killed several other Klingons. Chang accused Kirk of attacking them and then tried to launch a "counterattack" with Gorkon's ship. But instead, Kirk surrendered, and both he and the ship's doctor Leonard McCoy beamed aboard Gorkon's ship. Despite McCoy's efforts, Gorkon died and Chang arrested them both. (Despite his role in orchestrating Gorkon's death, Chang seemed genuinely affected by the death of his former comrade.) Gorkon's assassination was not enough to derail the peace process. The Federation President and Azetbur (who was the new Klingon Chancellor) were both determined to continue with this. The next meeting was set to take place at a neutral site, Camp Khitomer. The conspirators started to make plans to kill their next target: the Federation President. Meanwhile, Kirk and McCoy stood trial for Gorkon's assassination. Chang prosecuted them both and succeeded in having them both found guilty. However, the judge commuted a death sentence and sent them both to the penal asteroid Rura Penthe. Not satisfied with this, Chang ordered the commandant of Rura Penthe to make sure Kirk and McCoy were killed during an escape attempt. However, Kirk and McCoy's escape succeeded. Kirk and McCoy were rescued by Enterprise. Knowing that his enemy would find out where the peace conference was, Chang took the modified Bird of Prey to Khitomer to wait for him. As Chang predicted, the Enterprise arrived and tried to achieve an orbit of Khitomer. Safe from enemy fire in his invisible ship, Chang taunted Kirk and his crew with Shakespearean quotes. The Bird of Prey fired one torpedo after another, causing massive damage to the Enterprise. Another Federation ship, the Excelsior, arrived to help, but Chang only fired at it as well. For Chang, victory seemed very near. The Enterprise
