Elendil used Narsil in the War of the Last Alliance against Sauron. During the siege of Barad-dur, Elendil and Gil-gahad overthrew Sauron, but perished in the act, and Narsil broke into two beneath Elendil as he fell. Elendil's son and hei Isildur then used the hilt-shard of the sword to cut the One Ring from the hand of Sauron. Sauron's spirit fled and he was vanquished. Although his body was broken and power removed, Sauron's spirit survived when Isildur claimed the One Ring for his own.
Isildur took the shards home with him. Shortly before Isildur was killed in the second year of the Third Age in the disaster at the Gladden Fields, the shards of Narsil were rescued by Ohtar, squire of Isildur. He took them to Imladris, where Isildur's youngest son Valandril was fostered.
The Shards of Narsil became one of the heirlooms of the Kings of Arnor, and after the Northern Kingdom was destroyed they remained an heirloom of the Rangers of the North. The sword was reforged in Rivendell in 3019 T.A. during the War of the Ring, in celebration of the rediscovery and capture of the Ring with which it had become associated as its symbolic antithesis.
Thereafter it was renamed Andúril, (Sindarin for "Flame of the West"), by Aragorn, the heir of Isildur. He carried the sword during his journey south as one of the Fellowship of the Ring, and it featured prominently at several points in the story, where it was sometimes referred to as the Sword that was Broken or The Sword Reforged.
