Garrison Info? (Spelling?

[Nodachi]

Tonight i tried to complete the Garrison quest, using a decent amount of High Potions and still got fairly worked. I'm somewhat sure i can win if i get another shot at it but it won't let me redo it at the moment. I was wondering if anyone had a site with more info or knew themselves more about the quest.

Thanks in advance ~
