The Battle in the Bassen Rift was a conflict fought in 2379. The encounter was between the Sovereign-class USS Enterprise-E, assisted by two Valdore-type warbirds of the Romulan Star Empire, against the Reman warbird Scimitar, a unique and heavily armed spacecraft commanded by Shinzon. Shinzon was a clone of Starfleet Captain Jean-Luc Picard, the Enterprise's commanding officer, and had developed a vendetta against his originator. The resultant battle was a fierce engagement which ended with the defeat of the Scimitar, only thanks to sabotage from within the Reman starship itself, and left the Enterprise and the pair of warbirds severely damaged.
