English war letter:

Dear family, 
The day to day in here is quite unhappy. I feel miserable and lonely, I miss you a lot because without you, I feel empty.

Today I feel particularly unhappy. In fact, I'm both lonely and miserable. I miss you a lot as I feel empty in your absence.

My position as a sniper is hazardous. I follow the orders when the captain blows the whistle at us. We often need to run over and jump the wires without taking account our injuries and most of us drift over in that swampy place.

My role as a sniper puts me in danger. I follow the captain's orders as he blows his whistle at us. Often we're made to run and jump over wires, regardless of how much they hurt us. Most of us end up drifting around in that swampy terrain. 
The most horrible season in here is winter. It´s deadly cold and incredibly difficult to clutch a cup of chocolate or to get a hold of any food.

Winter is the most horrible season of them all. It's terribly cold which means that it's incredibly difficult to clutch a cup of hot chocolate or even to get any food.
We can´t flee and all of us are in the trenches slumpped on a floor completely full of mud and covered of rags.

We can't escape and so we are reduced to slumping on the floor dressed in our muddy rags. 
I hate those booby traps put by our enemies, who haven´t got compassion of us. They sometimes make an ambush when we only have just a little of ammunition prepared. We look at them with glare and also, we try to drag ourselves on the floor with our great-coats to protect us against them. That makes us fly up and duck because we only have a couple of minutes to save our lifes. 
But, I think that this war doesn´t need to take place. it´s not worth it, in spite of having different thoughts. 

I hate the booby traps that are planted by our uncompassionate enemies. Sometimes, they ambush us when we have insufficient ammunition. We glare at them and try to protect ourselves by using our great-coats* for cover. Given that we only have a very limited time to try to protect ourselves, we are made to fly up and duck(?). However, I do not think that this is worth the trouble overall.  
I hope all of you are well. 
Lots of love, 

(Name)

*Are great-coats a thing? If not, there's no need for the '-'
