Uruk-Hai
Uruk-Hai in the New Line film
Wicked Orc-like creatures created by Saruman in order to destroy men. The Uruk-Hai were first created by Sauron, who lent them all to his supposed ally Saruman. They mad more and more, and the uruks started killing trees and people as well as burning villages. They allied with Wargs and frequently attacked the Rohirrim. They won in the Battles of the Fords of Isen. But, when Saruman sent 10,000 of them to destroy Helm's Deep, They failed. Angered Ents then came to destroy the Uruks and they were finished. Saruman then gathered evil men to attack the Shire.
