On March 9, 3019, Prince Imrahil led a company of Swan Knights to Minas Tirith to help defend the City. Prince Imrahil led the sortie that rode to the aid of Faramir and the rear-guard who were retreating from Osgiliath when the forces of Sauron overran the Pelennor Fields on March 13. Shortly thereafter, the knights rode to the aid of the Rohirrim, fighting long and hard until the arrival of Aragorn.
