A couple of points, they don't have anything to do with the story itself, just habits to work on in your writing.
The first is simple. There are a fair number of mispelled words but that's easy to correct. The first step is to run the spell check on your word processor, and note the correct spellings of the words you missed. Do not count on the spell check to catch everything, though. It's a nice tool but is very
limited. Re-read the story several times, and read it aloud at least once. Your ear will catch some mistakes your eye has missed, and you will catch a lot of mistaked your spell check has missed.
The sccond is tense. Most of your story is told in the past tense, which is really good for fiction, but occasionally you slip into the present tense. Experienced writers will use the present tense sometimes but always because they have a specific reason for doing it. You never want to slip into it accidentally. Here's an example from the story...
The warrior’s eyes narrow as he knows what the white mans is right.
To fit with the tense of the rest of the section, this should be...
The warrior’s eyes narrowed as he knew what the white mans was right.
There are two mispelled words in the sentence also, but they're words that spell-check would not pick up...
The warrior’s eyes narrowed as he knew what (should be that) the white mans (should be man) was right.
Since I'm using this sentence as an example, I'll point out one more thing. This isn't connected to grammar or spelling so it may be less helpful to you, but...
The warrior’s eyes narrowed as he knew that the white man was right.
I suggest finding a better word than "knew." While it is true that Three Sticks knew that Quincy was right, the sentence is a little vague about when he came to this knowledge. I think you want a word that suggests that the knowledge came to him in that moment.
The warrior’s eyes narrowed as he realized that the white man was right.
I hope this is useful.
