This was a very good chapter, I must say. Orgulak is reasoning very well and Orc-like, I mean the idea of a surprise attack and revenge. He definitely is getting to be an interesting character. As for my previous review, I would have been less nit-picky if I had noticed there was an AU warning, since that makes the so-called "canon issues" largely to disappear. I look forward to the next chapter.
Overall, a nice start for your story, even though there could have been a bit more details about the Battle of Morannon, for instance.
There are a few issues with your story, though. First of all, you write about Orcs as if they were independent creatures like Men or Elves. That is not quite so, since they were created to be Morgoth's slaves and even if they were not mere puppets, their wills had been tied to that of Morgoth, and later Sauron. As the slaves of evil, they hated everything and everyone, including each other and their masters. So, it is a bit strange that Orgulak "harboured no hatred".
Another thing is that no Orc would have felt a duty to preserve a leader's memory, since they were tied to them only by fear of punishment. Orcs did avenge their fallen leaders sometimes (as far as I have read), but it stemmed more from their bloodlust than any respect towards the fallen.
As for the occupations of Orgulak's parents, I am afraid they are not very credible. The food needed in Mordor was grown in Nurn, by thousands of slaves from Khand and Rhûn. The sole occupation of Orcs was to be Sauron's soldiers and workforce in mines, roadbuilding etc.
One thing that is good in your story is the portrayal of Sauron. He indeed used the Orcs mercilessly and they died like flies. I also like the idea, an Orc renouncing evil (if that is what you have in mind). There are in any case few (at least few good)stories that have Orcs as main heroes. Your start is promising, if you write with a bit more detail in future.
I hope you won't take my review as a flame or nitpicking, I just wanted to give some advice.
Author's Response: Thank you for your insight. If Orcs were a pak of wild animals, than how could they maintain discipline in rank and command other creatures like Warg's, who coincidentally have a rudimentary form of communication? A pack of beasts that want only for bloodlust would have to be unleashed in battle, and would probably gorge anything in it's path, friend or foe. I submit that not enough research and fast has been written about Orcs, in general to qualify your facts and I propose that additional data should be devoted to the study of Orcs.
