Horrendous conditions, living in constant fear, extensive use of artillery so it was deafening, being ordered to charge over open ground to a certain death (or facing a firing squad for refusing), gains were measured in meters, not kilometers, disease killed nearly as many people as the enemies bullets, troops weren't rotated out like today so some may have been there for two years or more, savage hand to hand fighting where men were forced to bludgeon, stab or beat another man to death, rain would turn the trenches into mud pits where the wounded who couldn't stand would literally drown in mud... it would have been hideous. More.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
