Battle of Cair Andros

The Battle of Cair Andros was a battle that took place on the island of Cair Andros on the river Anduin.
While Aragorn led the forces off Gondor and Rohan to the Black Gate, he sent a small army of men, who were young men of Rohan and Lossarnach to retake the small island of Cair Andros. The group was successful in retaking the island from their enemies. Afterwards, the island would serve as a place of crossing and lead them from the island to Osgiliath down the Anduin.
