Unfinished Tales
A partial later version of "The Fall of Gondolin" was published in "Unfinished Tales" under the title "Of Tuor and his Coming to Gondolin". Originally titled "Of Tuor and the Fall of Gondolin," this narrative shows a great expansion of the earlier tale. Christopher Tolkien retitled the story before including it in "Unfinished Tales", because it ends at the point of Tuor's arrival in Gondolin, and does not depict the actual Fall.
