Tolkien had already completed most of the book, including the ending in its entirety, before the first nuclear bombs were made known to the world at Hiroshima and Nagasaki in August 1945.
Tolkien je već završio veći dio knjige, uključujući i kraj u cijelosti, prije nego što su u kolovozu 1945. godine nuklearne bombe bačene na Hirošimu i Nagasaki.
