In 2268, the crew of the USS Enterprise answered a distress call from a colony. There were a hundred men, women, and children in this colony. According to the distress call, they were under attack by an unidentified starship. When a Klingonbattle cruiser was detected approaching this planet, CaptainJames T. Kirk assumed that the Klingons were responsible for the attack. The Klingons steadfastly denied any involvement in the destruction of the colony.
The incident was later determined to be a fabrication created by an entity to incite a feud between the crews of the Enterprise and the Klingon battle cruiser. (TOS: "Day of the Dove")
