STARBASE
Name:	Starbase 391
Affiliation:	Federation Starfleet
Class:	starbase

Starbase 391 was located close to the Federation-Cardassian border.

In 2374 the Fifth fleet and Klingon Third Battlegroup retreated to Starbase 391 after the Battle of Guyra. (Star Trek: Swiftfire: "Over the Horizon")

Following that battle the USS Swiftfire-A spent the bulk of its time on patrol close to the station as part of its defence force. (Star Trek: Swiftfire: "Moral Actions")

The Raid on Sector 432 was launched from Starbase 391 after the Klingon Ninth Battlegroup replaced the Third Battlegroup. Following the battle both fleets regrouped at the starbase. The Fifth fleet was soon rotated back to the Vulcan border to get some respite from three months on the front. (Star Trek: Swiftfire: "Pressure Points")
