Grey Company
From Tolkien Gateway
The Grey Company was a company of Northern Dúnedain commanded by Aragorn's kinsman Halbarad. In the company of Elladan and Elrohir, they rode south to fight beside their Chieftain Aragorn in the War of the Ring. They found Aragorn near the Fords of Isen, accompanied him through the Paths of the Dead, and on to the Battle of the Pelennor Fields, where Halbarad fell.
