Third Marshal of the Riddermark

From Tolkien Gateway

The Third Marshal of the Riddermark was the third of the three Marshals who commanded the forces of Rohan. Like the Second Marshal of the Riddermark, the Third Marshal had no fixed duties, and his role changed according to the needs of his King. At the time of the War of the Ring, the Third Marshal was none other than Éomer son of Éomund, whose base of operations was at Aldburg in the Folde.[1]
