The book begins with Aragorn, who finds a dying Boromir. Boromir tells him that they were attacked by Orcs, who took Merry and Pippin with them. Boromir says he is sorry for everything and dies. Legolas and Gimli arrive. As a funeral, the three put Boromir's body in one of their boats, which they let fall down the waterfall Rauros. They find out that Frodo and Sam left them to go to Mordor, and that the Orcs that attacked them were Saruman's Orcs, who have taken Merry and Pippin. They decide to follow the Orcs westwards to save Merry and Pippin. West of the Emyn Muil they come into the land Rohan, home of the Rohirrim, the "Horse-lords". They meet a group of Rohirrim led by Éomer, nephew of King Théoden of Rohan. Éomer and his men have killed the Orc group on the border of the forest Fangorn, but did not see Merry or Pippin. Éomer gives them two horses, and Aragorn, Legolas, and Gimli ride to the Fangorn forest.
