This story is written in the third-person omniscient point of view. What that means is that the narrator is outside the story and that the reader is able to know the thoughts and feelings of all the characters.
The Guide to Literary Terms defines point of view:
Personal point of view concerns the relation through which a writer narrates or discusses a subject, whether first, second, or third person. If personal point of view is used and the writer assumes the point of view of a character, the author is writing in the first person. If the author takes the point of view of an observing character, the author is writing in the second person. If an impersonal point of view is taken, the author detaches himself completely and is an omniscient author, or third person.

both of you are correct because the point of view changes in the story. The story starts out as third person omniscient because of the description of the brothers and their thoughts. The point of view changes in places to third person limited and then again to third person omnisicient.
not third person omnicient
its third person limited because you do not know the inner workings and thoughts and feelings of all of the characters
