The Battle of Laktar was one of the fiercest conflicts of the Dominion War, fought in the Laktar system within the Klingon Empire. The Klingons were eventually the victors of this battle, though the large number of ships destroyed in the system flooded the region with radiation, making sensor scans impossible for months after the end of the war.

Captain Huss and her fleet joined the battle at its end. (TNG - The Brave and the Bold, Book Two novella: The Final Artifact)
