Some editions of the volume contain a synopsis for readers who have not read the earlier volumes. The body of the volume consists of books five and six. Book six has variously been titled
The Return of the King (clashing with the title of the third volume) and
The End of the Third Age, though in many editions the Books are untitled. The volume ends with a set of appendices and an index, varying in different editions.
Book V: The War of the Ring Sauron sends a great army against
Gondor.
Gandalf arrives at
Minas Tirith to warn
Denethor of the attack, while
Théoden musters the
Rohirrim to ride to Gondor's aid. Minas Tirith is besieged; the Lord of the Nazgûl uses a spell-wound
battering ram to destroy the city's gates. Denethor, deceived by Sauron, falls into despair. He burns himself alive on a pyre;
Pippin and Gandalf rescue his son
Faramir from the same fate.
Aragorn, accompanied by
Legolas,
Gimli, and the
Rangers of the North, takes the
Paths of the Dead to recruit the Dead Men of Dunharrow, oathbreakers who are bound by an ancient curse which denies them rest until they fulfil their oath to fight for the King of Gondor. Aragorn unleashes the Army of the Dead on the
Corsairs of Umbar invading southern Gondor. With that threat eliminated, Aragorn uses the Corsairs' ships to transport the men of southern Gondor up the
Anduin, reaching Minas Tirith just in time to turn the tide of battle. Théoden's niece
Éowyn, who joined the army in disguise, kills the Lord of the Nazgûl with help from Merry; both are wounded. Together, Gondor and Rohan defeat Sauron's army in the
Battle of the Pelennor Fields, though at great cost; Théoden is among the dead. Aragorn enters Minas Tirith and heals Faramir, Éowyn, and Merry. He leads an army of men from Gondor and Rohan, marching through Ithilien to the Black Gate to distract Sauron from his true danger. At the
Battle of the Morannon, his army is vastly outnumbered.
Book VI: The End of the Third Age Meanwhile, Sam rescues Frodo from the tower of Cirith Ungol. They set out across Mordor. When they reach the edge of the
Cracks of Doom, Frodo cannot resist the Ring any longer. He claims it for himself and puts it on.
Gollum suddenly reappears. He struggles with Frodo and bites off Frodo's finger with the Ring still on it. Celebrating wildly, Gollum loses his footing and falls into the Fire, taking the Ring with him. When the Ring is destroyed, Sauron loses his power forever. All he created collapses, the Nazgûl perish, and his armies are thrown into such disarray that Aragorn's forces emerge victorious. Aragorn is crowned King of Arnor and Gondor, and weds
Arwen, daughter of Elrond. Théoden is buried and Éomer is crowned King of Rohan. His sister Éowyn is engaged to marry Faramir, now Steward of Gondor and Prince of Ithilien. Galadriel, Celeborn, and Gandalf meet and say farewell to Treebeard, and to Aragorn. The four hobbits make their way back to the Shire, only to find that it has been taken over by men directed by "Sharkey" (whom they later discover to be
Saruman). The hobbits, led by Merry, raise a rebellion and
scour the Shire of Sharkey's evil.
Gríma Wormtongue turns on Saruman and kills him in front of
Bag End, Frodo's home. He is killed in turn by hobbit archers. Merry and Pippin are celebrated as heroes. Sam marries Rosie Cotton and uses his gifts from Galadriel to help heal the Shire. But Frodo is still wounded in body and spirit, having borne the Ring for so long. A few years later, in the company of Bilbo and Gandalf, Frodo sails from the
Grey Havens west over the Sea to the
Undying Lands to find peace.
Appendices The appendices outline more details of the history, cultures,
genealogies, and
languages that Tolkien imagined for the peoples of Middle-earth. They provide background details for the narrative, with much detail for Tolkien fans who want to know more about the stories.
"Annals of the Kings and Rulers" Provides extensive background to the larger world of Middle-earth, with brief overviews of the events of the first two Ages of the world, and then more detailed histories of the nations of Men in Gondor and Rohan, as well as a history of the royal Dwarvish line of Durin during the Third Age. The embedded "
Tale of Aragorn and Arwen" tells how it happened that an immortal elf came to marry a man, as told in the main story, which Arwen's ancestor
Lúthien had done in the
First Age, giving up her immortality.
"The Tale of Years" (Chronology of the Westlands) Provides a timeline of events throughout the series, and ancient events affecting the narrative, and in lesser detail, it gives the stories' context in the fictional chronology of the larger mythology. It tells that Sam gives his daughter Elanor the fictional
Red Book of Westmarch – which contains the autobiographical stories of Bilbo's adventures at the opening of the war, and Frodo's role in the full-on War of the Ring, and serves as Tolkien's source for
The Hobbit and
The Lord of the Rings (with Tolkien representing himself as a translator, rather than an
epic novelist). It says that there was "a tradition" that after handing over the book, Sam crossed west over the sea himself, the last of the ring-bearers; and that some years later, after the deaths of Aragorn and Arwen, Legolas and Gimli also sailed together "over Sea".
"Family Trees" (Hobbits) Gives
hobbit genealogies – not only for Bilbo and Frodo's Baggins family, but also their relations the Tooks and Brandybucks, which connect them to Pippin and Merry.
"Calendars" Describes some of the calendars used by the characters in the story, and explains that the Roman month names in the text are "translations" of the names in the hobbits' calendar. (Tolkien was a linguist, and provided Germanic-sounding names for the hobbit calendar by extrapolating names of
German and Old English months forward to what he thought they might have become if all were still used in modern English, as
Yule and
Easter are.)
"Writing and Spelling" Describes dwarves' runes and the elvish runes used by the other peoples of Middle-earth; the names of the runes and letters incidentally give some information about dwarvish and elvish languages.
"Languages and Peoples of the Third Age" and "On Translation" Presented as two sections. In addition to outlines of the various languages in current use during the narrative, and mentioned or seen in the story, it discusses hobbits' names at length. It sorts out names which Tolkien
pretended to have translated into English, and names which he said he had left in their original form (since they had no meaning in hobbits' everyday language). == Reception ==
