Lancel IV is said to have beheaded the ironborn king Harrald Halfdrowned and his heir with a single stroke of Brightroar, the Valyrian steel greatsword of House Lannister, during the Battle of Lann's Point.
When Gyles III Gardener, King of the Reach, was away battling the Storm King in the east, Lancel attempted to cut a piece out of the Reach for himself. According to Ser Eustace Osgrey, his ancestor Wilbert fought against Lancel as the Osgreys were Marshalls of the Northmarch. Although Lancel nearly cut Ser Wilbert in half with Brightroar, the dying Little Lion was able to stab his dagger through a gap in Lancel's armor to kill the king. Eustace claimed Lancel's men returned to the westerlands after Lancel's death, as they did not want to fight on after the death of their king.
According to Maester Yandel, Lancel IV died at Red Lake during his invasion of the Reach. Yandel writes that Gyles halted his own conquest and returned home to the Reach to deal with Lancel's westermen. Had Lancel not invaded the Reach, Gyles might have been able to complete his conquest in the stormlands.
