Cestus III Massacre

The Cestus III Massacre was the name of the brutal slaughter of the Federation outpost on Cestus III by the Gorn who believed the colony was an intrusion on their Hegemony.

The Gorn attack killed all the inhabitants of the planet and left only one survivor who managed to inform the Starfleet ship USS Enterprise (NCC-1701) which responded to the distress call. The Gorn warship escaped from the planet with the Enterprise in pursuit whereupon a Metron disabled both ships and forced Captain James T. Kirk and the Gorn Commander into combat which resulted in a lasting peace to be established between both parties. (TNG novel: Requiem)
