Captain Rachel Garret was the captain of the USS Enterprise NCC-1701-C. In 2344, she responded to a distress call from the Klingon outpost Narenda III. Finding four Romulan Warbirds attacking the outpost, she engaged them to defend the outpost. A sudden barrage of torpedo fire opened a temporal rift, and the ship fell into an alternate future where the Federation had been at war with the Klingon Empire for over 20 years. There, the ship was found by its own future successor, the Enterprise-D.
Captain Garret made the difficult decision to go back through the rift to her own time, where her ship would almost certainly be destroyed, but Klingon warships discovered the two Enterprises before the ship was ready to return. During an attack by the Klingons, Captain Garrett was killed, leaving Lieutenant Castillo in command.
