 The published "Children of Húrin" is essentially a synthesis of the "Narn" and of the account found in the "Silmarillion".The first part of "The Children of Húrin" (chapters I to VII) is taken directly from the "Narn" with the exception of the Nírnaeth Arnoediad (chapter II), which actually forms the twentieth chapter of the "Silmarillion"; both in the "Narn" and in the much compressed "Silmarillion" version ("Of Túrin Turambar"), this battle is only briefly mentioned.In the middle section (chapters VII to XII), that is, from the end of Túrin's residing on Amon Rûdh to his return to Dor-lómin, material is mostly drawn from the "Silmarillion" but is often supplemented with more complete but disconnected passages from the "Narn" (provided by Christopher Tolkien in the Appendix of the "Unfinished Tales").
