Duel at Weathertop

After escaping Isengard, Gandalf the Grey went to Rohan and took the steed known as Shadowfax. Gandalf headed to Weathertop because he thought the Nazgul had Frodo. At night, the Ringwraiths and Gandalf the Grey fought. Gandalf managed to hold his own all night--in the morning, Gandalf rode Shadowfax out of Weathertop and four Ringwraiths chased after him. This allowed Strider and the Hobbits to only face five Nazgul at Weathertop.
