KILLING MENTALITY: WWI Soldier's Combat Experience
The Allied Commanders and psychiatrists of WWI believed that soldiers broke down, or suffered shell shock, because in their minds, men in the trenches had not been "hardened" enough. Their thinking was civilians which was what the Canadian Expeditionary Force was comprised of were not made to be natural warriors and that it would take a great deal of training to make these men into proficient soldiers. Training was to be simple, continuous and varied and were to be trained for one purpose only which was to fight.
