: "...entombing ten thousand of their number behind as
: many tons of shattered rock."
: Notice the "behind". They weren't crushed, they
: were trapped. It never says any dwarves died just that
: they blocked the entrance and trapped themselves in
: the city.
Actually "entombed" is a pretty harsh word. It would tend to mean that when all those tons of rock came crashing down, the dwarves left inside were doomed to die by starvation. If they had escaped they wouldn't have been _entombed_ now would they?
