Operation Return was the codename for the joint attack on Deep Space 9 by the Federation and Klingon Empires in 2374. The objective of the mission was to recapture the station and regain control of the Alpha Quadrant side of the Bajoran wormhole so to prevent Dominion reinforcements from the Gamma Quadrant. (DS9: "Favors the Bold"
The operation was successful with the USS Defiant preventing the arrival of the Dominion reinforcements in the Alpha Quadrant. The Federation and Klingon fleet routed the larger Dominion forces resulting in the Dominion abandoning Deep Space 9 allowing it, and the wormhole, to return to Federation control. (DS9: "Sacrifice of Angels")
In an alternate universe, Operation Return was a massive defeat for the Federation and Klingon Empire. The Defiant was destroyed in the wormhole and the Dominion reinforcements flooded into the Alpha Quadrant. After the rest of the fleet lost contact with the Defiant they proceeded to Deep Space 9 in the hopes the mission could still be a success. Instead the fleet stumbled into a trap. The fleet was surrounded by the Dominion's reinforcements, which destroyed ever single Federation and Klingon ship. This defeat would eventually lead to the Federation and Klingons losing the war.
