Battle of the Pelennor Fields
Gimli then accompanied Aragorn, Legolas, a company of Rangers of the North, and Elrond's sons Elladan and Elrohir on the Paths of the Dead. At the stone of Erech, Aragorn summoned the Dead Men of Dunharrow, spirits bound by oath to fight for the king of Gondor, which Aragorn rightfully was. Gimli witnessed the Dead rout invaders at Pelargir in south Gondor by the power of fear alone. After Aragorn declared the spirits' oath fulfilled, the men of south Gondor gathered to his banner, and they sailed in the enemy's abandoned ships to relieve the siege of Gondor's capital Minas Tirith. Their arrival led to victory in the Battle of the Pelennor Fields.
