Rachel Garrett was the commanding officer of the U.S.S. Enterprise-C until 2344, when the ship was sucked into a temporal rift while defending the Klingon colony in the Narendra System against the Romulans. The Enterprise-C emerged in the year 2366 of an alternate timeline, where the Federation was losing a war against the Klingon Empire. The U.S.S. Enterprise-D of that reality assisted its predecessor ship to return, but her helmsman Richard Castillo had to take command as Captain Garrett was killed during a Klingon ambush shortly before they could make their historical sacrifice for Narendra, and thereby delaying the Federation-Klingon War by 40 years.
