Welcome to the Downs,
Etharius! But if you ever want to have a social life of any kind, leave now! Look at my sig; you'll never get out!
Anyway. *looks around suspiciusly*
You should definitly read the Silmarilion, and the innumerable other books raleted to Middle-Earth. You'll find that the Elves do quite a bulk of the fighting. Especially Fingolfin

.
In my opinion, the elves were all either dead, gone over to Valinor, or simply tired of fighting. Many of them still did, the Mirkwood elves is an example of this, because thier lands were threatened.
