The Lordship of Balin was short-lived. Ori, who was with him in Moria, recorded in the last pages of the Book how an army of Orcs came unexpectedly out of the east, slaying Balin outside the East-gate. The Dwarves defended themselves, but they were beleaguered from the east by the Orcs and from the west by the mysterious Watcher in the Water. Their last stand was in the Chamber of Mazarbul, where the Orcs eventually overcame and destroyed them.
The victorious Orcs seem not to have understood the significance of the Book, so that rather than carrying it off or destroying it; they left it to rot in the Chamber. There it was found twenty-four years later by the Company of the Ring, burned, slashed and blood-stained, and missing a number of pages, but still readable in some parts. Gandalf passed it to Gimli to return to King Dáin, after which nothing more is heard about it. If Gimli was able to keep it through the battles that followed, and didn't discard it with his gear at Parth Galen, it is possible that he carried it throughout his travels in Middle-earth, returning it at last to Dáin's heir Thorin III in Erebor.

- In the novel of The Fellowship of the Ring the book is found and kept for Dain Ironfoot; in the movie version it is found but lost again.
- In the film adaptation, the text of the book is different: "They have taken the bridge and the Second Hall. We have barred the gates but cannot hold them for long. The ground shakes...drums, drums in the deep. We cannot get out. The shadow moves in the dark. We cannot get out. They are coming."
