Arcane Topic Warning: Part the Second

[Raynor]

I don’t think the Petty-Dwarves would have attacked Elves in the first place unless they were in a position of great superiority (I think we can probably all agree on that). On the other hand, if the Elf was really alone or even if there were a few of them, there would not likely be any survivors to say who did it

The petty dwarves seem pretty savage so as to act based on basic fight/flight instincts - esspecially since they didn't know the might of the first elves. I would say they clearly underestimated the elves' might and I think there were very few (if any!) casualties among the eldar. (Moreover, the elves have been dealing with Melkor's minions ever since they were born.)
