Chapter 6-10 book 6
Eventually, Frodo and his companions decide to return home. Arwen gives Frodo her place on the ships that carry the elves to the Undying Lands beyond Middle-earth, should he find the memory of his journey unbearable. Accompanied by all their friends and the elves of Lothlórien and Rivendell, the hobbits begin the leisurely journey home. First, they travel to Rohan, where Éomer and Éowyn give Merry an ancient horn, whose sounding is said to hearten friends and frighten enemies. At Isengard, they learn that Treebeard has let the greatly diminished Saruman go, along with Wormtongue. As the group travels north, they come upon Saruman himself, traveling like a beggar with Wormtongue. Gandalf offers him a last chance, which he spurns.

Only the four hobbit-friends remain when they reach the Brandywine Bridge.
They find the gate locked and a new ugly guardhouse built on the far side, and Merry and Pippin scale the gate to get in. A man comes out to quell the ruckus, but he runs away rather than deal with armed and determined resistance. The travelers soon learn that Lotho Sackville-Baggins has brought evil men into the Shire to intimidate the hobbits, ruling by a combination of force and fear. Many trees have been cut down and hobbits have been turned out of their homes, while factories have been built that pollute the environment. The four friends lead a rebellion, then find Saruman, still accompanied by Wormtongue, living in Bag End. The fallen wizard has masterminded this
