War is the bloodiest event humankind has known. It destroys millions of lives and leaves only pain, suffering, and death in its wake. In war, people lose their lives, their homes, their loved ones, but the people that lose the most in war are not civilians but soldiers because they do not just lose their comrades, friends, loved ones, homes. They lose themselves. To be a soldier you have to be mentally and physically tough and brave because they suffer through the bloodiest battles and witness horrendous scenes of murder and torture in war. The wars that took the greatest number of lives are the World wars. Soldiers in these wars suffered many mental and physical illnesses. Some came out of the war as heroes but some got mentally and physically wrecked because they were turned into killing machines be it of their own volition or against their will. Here the duality of war can be seen because some men are considered war heroes either because they saved many lives or because they took many lives. A soldier can thus be either a hero or a monster. This thesis is about the worst battles of the Second World War depicted in the novels The Naked and the Dead and From Here to Eternity and the movies Hacksaw Ridge and Saving Private Ryan. It is also about the soldiers who suffered through those battles. It will show what physical and mental damage the war left on them and why the war is considered both glory and doom of humankind.
