Well, I am going to start with the negatives. The punctuation was a little off. Spelling was okay, nothing major, but your use of capital letters is a little bad. Remember, after a full stop, use a cap. The name of something/someone, use a cap. After a question mark or an exclamation mark, use a cap. And, every time someone talks, start a new line, makes it look nicer, and it's correct. And, try and paragraph more, and some bigger chapters couldn't hurt right?
The positives. The description was very good detailing the fight, could have used a little more description of the area around them though, but I digress. I like how tough you made the battle for Fred, showing that Spartans are very hard pressed to win in hand to hand against Elites, being very strong. The plot is good, and has good potential, you just have to work on your negatives :)
