Many authorities speak and write of emotional stamina on the battlefield as a finite resource. I have termed this the Well of Fortitude. Faced with the soldier’s encounters with horror, guilt, fear, exhaustion, and hate, each man draws steadily from his own private reservoir of inner strength and fortitude until finally the well runs dry. And then he becomes just another statistic. I believe that this metaphor of the well is an excellent one for understanding why at least 98 percent of all soldiers in close combat will ultimately become psychiatric casualties.
