As of 3059 the Congress-class frigate Bucephalus was a WarShip within the Clan Hell's Horses touman and was serving as the CHH Bucephalus. The Bucephalus would continue to be an active part of the touman throughout the next decade.
Following the beginning of the Hell's Horses campaign against their former allies in Clan Ice Hellion during Operation ICE STORM, the Ice Hellion invasion of the Clan Jade Falcon Occupation Zone in the Inner Sphere, the Bucephalus would see action against at least one Ice Hellion WarShip. The Bucephalus is known to have engaged the Lola III-class destroyer CIH Cold Hunter in the Apollo system as the Cold Hunter attempted to cover the retreat of the Ice Hellion's Zeta Galaxy; the Bucephalus came close to destroying the lighter ship, and the damage inflicted by the Bucephalus was directly responsible for the Cold Hunter's subsequent surrender during an engagement in the Dark Nebula in March 3072.
In the aftermath of the Jihad Clan Wolf began a series of strikes against the Hell's Horses territory in the Inner Sphere, and in January 3081 the Bucephalus found itself facing down Clan Wolf forces while fighting alongside a former Ice Hellion WarShip - the York-class destroyer CHH Stampede, formerly the CIH Pack Leader until her capture by the Hell's Horses.
The Bucephalus and the Stampede were involved in the defense of Kirchbach in the face of a determined Trial of Possession from the Wolves' Gamma and Kappa Galaxies escorted by the CWS Rogue, another Congress-class frigate. The Wolf forces were overconfident, underestimating the Hell's Horses strength in the system, and the Stampede and the Bucephalus proceeded to inflict substantial damage on the Rogue; Kappa Galaxy then lost almost half its strength on the approach to the planet as the DropShips were torn apart on approach. The attack was ultimately unsuccessful, with both Wolf Galaxies outfought on the ground and forced to surrender.
