The 5th Fleet was a Federation Alliance fleet that participated in the Federation/Dominion War.
Later in 2374, Benjamin Sisko developed a counter attack against the Dominion, in hopes of recapturing Deep Space 9, by putting together a large task force comprised of elements of the Second Fleet, Fifth, and Ninth Fleets.
Once Sisko was given the "go ahead" from Star Fleet Command, the Fifth Fleet was ordered to pull out of fighting along the Vulcan border and regroup at Starbase 375. This strategy was cause for concern to those in the Dominion watching Federation fleet movements, including Damar and Weyoun.
The combined fleet later encountered a Dominion fleet in a successful engagement, in a region of space between Deep Space 9 and Starbase 375. Among the ships in this combined fleet were the USS Centaur, USS Cortéz, USS Hood, USS Magellan, USS Majestic, USS Sarek, USS Sitak, and USS Venture.
