Battle of the Crossings of Erui
From Tolkien Gateway
The Battle of the Crossings of Erui was the last battle of the Kin-strife of Gondor.
After a decade of cruel rule by Castamir the Usurper, the people of Gondor rebelled, and the rightful king Eldacar returned to his Kingdom.
Castamir and his men were cornered at the Crossings of the river Erui, on the road from Minas Tirith to Pelargir, and Eldacar personally killed Castamir there.
Castamir's heirs were then besieged in Pelargir after the victory, eventually fleeing to Umbar. However, many Númenóreans of pure blood were killed at Erui.
