According to the info gained by the lady redguard quest and the alikr assassins or supposed like so who is right in what happened?

In short, 10 years of bloody war with, and occupation by, the Aldmeri Dominion.http://imperial-library.info/content/skyrim-concises-account-great-war-between-empire-and-aldmeri-dominion

What about the Taneth city , is right the redguard girl in the tavern or the assassins?

I've not actually finished the quest yet. What were the two options?

she says the guys are sent by other rival noble houses and she had to flee and hide there in the tavern , the alikr say she is a nobleman betrayer that gived the city of taneth tothe aldmer ....
