Your commanding officer just gave you the orders to attack the Enemy line, its 4 miles away riddled with craters and devils wire, as you leave the trench the enemy starts raining down artillery on you, with bullets zipping by your head you some how reach the Enemy line only to realize the wire is to thick to cross and the enemy is just shotting fish in a barrel as men become entangled in the wire, your order to fall back with the Enemy still blasting away at you, across craters, barb wire the dead and wounded your able to make it back to your line only to be told you will be doing the same thing tomorrow morning. As morning comes you see a fog roll over the field but as you see crows fall from the sky you realize its poisons gas, as it rolls in to the trench all you can do is make makeshift mask and hope for the best.
