Ambush of the Wargs

Ambush of the Wargs
When the refugees and the Rohan Army marched to Helm's Deep, they were ambushed by warg riders led by Sharku. Háma, Théoden's bodyguard, was killed at the beginning of the battle. After a short battle, the Wargs were routed, and Aragorn mortally wounded Sharku before toppling over a cliff and into a river below. He was believed to have perished, but he survived, and arrived later at Helm's Deep after spotting the Army of Isengard. However, this battle only appears in the movies. In the book it does not happen.
