§ Of the Ruin of Beleriand and the Fall of Fingolfin The Silmarillion

When seven years had passed since the Fourth Battle, Morgoth renewed his assault, and he sent a great force against Hithlum. The attack on the passes of the Shadowy Mountains was bitter, and in the siege of Eithel Sirion Galdor the tall. Lord of Dor-lómin, was slain by an arrow. That fortress he held on behalf of Fingon the High King; and in that same place his father Hador Lórindol died but a little time before. Húrin his son was then newly come to manhood, but he was great in strength both of mind and body; and he drove the Orcs with heavy slaughter from Ered Wethrin, and pursued them far across the sands of Anfauglith.
