During the Long Winter of TA 2758 - TA 2759, the Corsairs of Umbar attacked Gondor, and Rohan came under attack from the Dunlendings. Initially, both nations were under attack, and neither could help the other. Once the Corsairs attacking Gondor had been defeated, Beren sent a force under the command of his son Beregond north to the aid of Rohan and its war with the Dunlendings.
In TA 2759 Saruman suddenly appeared and requested leave to dwell in Isengard, Beren gladly gave the Keys of Orthanc to Saruman and appointed him Warden answerable only to the Steward, because he believed Saruman could help both Gondor and Rohan recover from the effects of the Long Winter.
