Battle of Cheron

The Battle of Cheron was the pivotal battle during the Earth-Romulan War that ended with the crushing defeat of the Romulan Star Empire.

It was during this battle, that Terran forces were able to turn the Romulans back into their own territory and prevent an invasion of Earth for good.

Earth's space forces, led by Jonathan Archer and Enterprise, were able to destroy and disable 90% of the Romulan forces making their advance, a force that was already crippled due to the Romulan loss of their staging grounds in Sector 2148.

Seven Romulan vessels were taken by force with boarding parties. Four of the seven vessels taken were led by MACO Major Matt Clow and the 501st Strike Force, which was stationed temporarily aboard Enterprise.

Aftermath
Following the battle, some commanders in the United Earth forces wanted to continue on pushing the Romulans back all the way to Romulus and deal them a death blow which would destroy all their shipbuilding facilities and rule the Romulans out as a major threat. However, cooler heads prevailed and it was decided that as the Romulans were a proud people, total defeat would humiliate them, and would lead to future conflicts. Instead it was decided to leave the Romulans dignity intact. (TOS novel: My Brother's Keeper: "Republic").

Even into the 24th century, the battle remained an intense embarrassment for the Romulans, which according to Alidar Jarok, would be retributed by "the new leaders" on Romulus, who "vowed to discard the treaty and claim the Neutral Zone," with Nelvana III being the first step.
