Battle of Earth (Undine invasion)

The Battle of Earth was the opening conflict in the brief Undine invasion of the Beta Quadrant. Intended as a diversion for the allied Beta Quadrant forces, it resulted in the defeat of the Undine invasion force and the discovery of the Undine's true goal of the destruction of Qo'noS.

Conclusion
Following the defeat of the Undine impersonating E'genn, the Undine impersonating Eric Cooper made telepathic contact with Tuvok, who "reversed" the contact and uncovered the Undine attack on Qo'noS and the Undine plan to destroy the planet. Following this discovery, the allied Federation and Romulan Republic forces departed the Sol System for Qo'noS to repel the invasion.
