The Groumall was a freighter that was in service with the Cardassian military in the late 24th century. Gul Dukat was assigned command of the Groumall after he was demoted for bringing his illegitimate daughter, Tora Ziyal, back to Cardassia Prime. Glinn Damar also served on board as the first officer.
In 2372, the Groumall transported Major Kira Nerys from Deep Space 9 to Korma. Upon arriving at Korma, they found the outpost destroyed, and were thereafter confronted by the Klingon Bird-of-Prey, commanded by K'Temang, that was responsible for the attack. Dukat attempted to confront the Bird-of-Prey, but the Klingons declined to attack such a helpless vessel.
After the encounter, Dukat and Kira mounted a system-5 disruptor from Korma's planetary defense system inside the Groumall's cargo hold and followed K'Temang to Loval. The disruptor fired effectively on the Bird-of-Prey, but the freighter was itself severely damaged when the Klingons returned fire. After beaming aboard the Bird-of-Prey, Kira managed to switch the crews of the two ships via transporter, and Dukat then used the Bird-of-Prey's weapons to destroy the Groumall with the Klingons aboard.
