The Battle of Earth was a major battle between the Undine and the United Federation of Planets, Romulan Republic, and Klingon Empire during the Undine War.
Overview[]
The Battle of Earth was the first major battle of the Undine invasion of the Beta Quadrant. It was actually a diversion, to make the allied Beta Quadrant forces defend Earth while the Undine achieved their true goal which was the destruction of Qo'Nos the Klingon homeworld. A combined force of Starfleet, Romulan, and Klingon starships engaged the Undine bio-ships. It was a battle which resulted in extensive damage to the Earth space dock and the lost of a number of Starfleet vessels, which ended upon the annihilation of the Undine attacking force.
Aftermath[]
Due to the telepathic contact established between Tuvok and the Undine impersonating Eric Cooper, they learned that the attack on Earth was a diversion and that the Undine were going to destroy Qo'Nos with one of their planet killers. The combined fleet then departed to help defend the Klingon homeworld. (STO mission: "Surface Tension")
