Seeking help against the Movellan virus, the Daleks decided to attack the station and retrieve Davros so he could provide that help. The Dalek Supreme was on a single Dalek Battlecruiser which quickly destroyed the station's defence fighters. The cruiser then opened fire on the station, killing the Captain and half the crew. A small contingent of Daleks then stormed the ship, backed up by their Dalek duplicate troopers led by the mercenary Gustave Lytton who, after killing Osborn, released Davros.
