According to a scene cut from the episode "Valley of Darkness, Brenig was a colonial ship which was boarded by Cylon forces during the second year of the war. It was apparently a small vessel, with a crew of approximately 75, only 20 of whom survived the attack. Then-Petty Officer Saul Tigh was among the survivors, at that time a teenager serving as gunner's mate.
He recounted that the Cylon boarding party engaged his crew in hand-to-hand combat in a battle over the ship's ammunition magazines. By the end of the war, they would abandon this tactic in favor of venting a ship's atmosphere and turning its guns against its allies.
