In late 2256, the United Federation of Planets was slowly but surely losing the Federation Klingon War. Klingon forces were pushing against the Federation lines and slowly moving the border back. The Klingons would score one of their largest victories when at least six Klingon birds of prey were able to commit a surprise attack upon the blockading forces of Corvon II and completely destroy them. The birds of prey were then able to dispatch the additional patrol craft protecting the planet. Corvon II supplied the Federation with over 40% of its dilithium. The loss of Corvon II would mean that Starfleet would lose the war. Corvon II, having one of the more sophisticated shields in the galaxy, was able to activate its defenses before the birds of prey got there. However, even with superior shielding, they would only be able to survive a little over six hours before the Klingons would be able to breach the shields and destroy the colony. For over five hours, the Klingons would relentlessly attack the colony itself. The colony structure would still begin to degrade and at least 200 colonists would lose their lives. Ultimately, the shields of Corvon II would fall and the Klingons would begin making attack runs on the colony itself. The USS Discovery would initiate its first successful, sport drive jump and arrive right above Corvon II's mining facilities. It would fire immediately upon two birds of prey, destroying them. The Discovery would sit stationary as the birds of prey would move their target from Corvon II to the Discovery. Even though the Discovery had destroyed two Klingon vessels, it would not fire on the other ships. Captain Lorca would order that the Discovery remain stationary, waiting for the ships to get ever and ever closer. The Klingonships would continue to pound on the Discovery, quickly beginning to drain its shields. And what would become known as the Lorca maneuver, Discovery would wait for the birds of prey to get at zero range and then activate the sport drive, leaving only activated torpedoes behind. The torpedoes would detonate destroying all of the Klingons ships. Even though the same outcome would have probably occurred, had they simply just fought them right out using the phasers that destroyed them in one hit. Moving on, the colonists of Corvon II would rush out to see the Klingonships destroyed. They had been saved.
