<P> Eventually Sauron emerged from the tower and engaged the Alliance forces personally near Orodruin, battling the commanders Gil - galad and Elendil, with only Elrond, Círdan, and Isildur standing by them . Gil - galad and Elendil were slain, with the latter's sword Narsil breaking beneath him as he fell . Sauron was also overthrown and then Elendil's son Isildur used the hilt - shard of Narsil to cut the One Ring from Sauron's hand . </P> <P> Bereft of the power of the One Ring, Sauron's physical form was unbound and his dissipated spirit would not take form again in Middle - earth for two and a half thousand years . After the victory over Sauron, the death of Gil - galad and Elendil, and irreplaceable casualties to the Elves, the Last Alliance dissolved . </P> <P> The Eldar mourned the victory as bittersweet for the loss of their king and that the One Ring was kept by Isildur, who was entrapped by its power and could not bear to think of its destruction; later, he perished and lost the ring in the Gladden Fields . Thus, despite the sacrifice of the Elves and Men, the Ring was not destroyed and the opportunity to defeat Sauron once and for all was missed . The war resulted in the first weakening of Lindon and Arnor . The Second Age ended with the war's conclusion and the Third Age of the World began . </P> <P> In Peter Jackson's The Lord of the Rings: The Fellowship of the Ring, the details of the war are not included and only the final "Battle of Mount Doom", as it is sometimes called, is shown . Notable differences from the book are: unidentified Gil - galad is briefly glimpsed, but his death is not shown; Sauron kills Elendil with his mace; Narsil is broken under Sauron's foot into many pieces, instead of two; Isildur cuts off most of Sauron's fingers on his outstretched hand, instead of just one; Sauron eventually explodes; Anárion and Círdan are omitted overall . </P>
