You need to add punctuation in this piece, because it would read better and make more sense.
--------------------------------

"Horses charge people scream
blood is drawn it feels the stream"

First line: A comma should be placed after "charge".

Second line: A comma should be placed after "drawn".
-----------------------------------

"body's lay were once people had once been
you hear the screaming you feel the pain"

First line: "body's" should be "bodies".

First line: Erase the first "once" because repeating it just ruins the flow for me.

Second line: Comma after "screaming".
----------------------------------------

"fear fills the air
shallow graves shallow lifes
beyond the mist the shadows appear"

Great wording here and imagery portrayed.

Second line: Comma after "graves".
----------------------------------------

"in the silence i can't think straight
i try to speak but no words come out
what am i thinking were do we go from here
on this battlefield of hope and fear"

First line: "i" should be "I".

Second line: "i" should be "I".

Third line: I don't know which you mean: "what am I thinking? Where do we go from here?" or "what I am thinking is where do we go from here?". Sounds and reads much better, either one.

Fourth line: Good wording and ending.

4/5 from me, this poem felt rushed and I suggest going back and spending more time on this piece to correct the errors I pointed out. Also, capitalize the beginning words of each new line (I mean the first letter of that beginning word).

Take care and God Bless!

Happy Easter!
