Side question. Does the book ever mention what Sauron did with the dwarven rings he recovered? The book says all the rings were either lost in Dragon fire or gained by Sauron. I would assume that Sauron has at least 2 or 3 of them and has passed them to loyal assistants.
Not AFAIK. IIRC, 4 (maybe it was 5 - going from memory here) were destroyed by dragonfire. That leaves 3 (or 2).
IIRC, Thrain (Thorin's father) was the bearer of the last Dwarven Ring (IOW, all the others had been destroyed or captured by Sauron at this time) - which was taken from him when he was captured by the forces of Sauron and before Gandalf found him and received from him the map and key later given to Thorin at the beginning of the Hobbit. That leaves but 2 (or 1) unaccounted for.
Also, IIRC, it was said that the dwarves could not be turned by the rings into Ringwraiths, even though their rings were tainted by the One Ring (IIRC, the three elvish rings were not)... for whatever reason, dwarves seemed somewhat resistant to the "fading" effects of the rings.
Also, I remember from Unfinished Tales that once they had fallen slave to Sauron, the Ringwraiths were controlled by the 9 rings - which were then in possession of Sauron. This indicates to me that Sauron would have liked to have dwarven servants with the 2 unaccounted rings (or 1) but because of the nature of the dwarves, did not - Thrain was demonstrably not a servant of Sauron, though quite insane when Gandalf found him (not able to remember his own name, nor Thorin's name). Presumably these 3 (or 2) - including the one recovered from Thrain in this count - were used to help him boost his own personal power, rather than to increase his power through controlling thralls.
My 2 cents, though I'm sure someone who knows better than me will correct me.
