Improve your spelling for a start so your tutor can understand what you are writing.
Where was the battel of somme? wasn’t it in Russia or Germany? :S
Why don’t you read some read WW1 diaries which might hopefully give you some ideas:

I’m not suggesting that you copy these verbatim, but it will hopefully inspire your writing style and content.

Please rate my answer if you found it useful.
Dont dwell too much on how he died, you should impart how it made you feel to the reader. You have to live with the sight of his mangled corpse in your mind til your dying day. Think of his family and those who relied on him before he went away; how will they miss and remember him as time passes.
