Hitler already showed traits that characterized his later life: inability to
establish ordinary human relationships, intolerance and hatred of especially
the Jews, a tendency toward denunciatory outbursts, readiness to live in a
fantasy-world and so to escape his failure.
He learned to loathe brilliant, charming, cosmopolitan Vienna for what he
called its Semitism. More to his liking was homogeneous Munich, his real home
after 1913. To this man of no trade and few interests World War I was a welcome
event which gave him some purpose in life.
So Adolf Hitler went to Munich, Germany and when World War I began in 1914, he
volunteered for service in the German army. Hitler was twice decorated for
bravery, but only rose to the rank of corporal.
When World War I ended Hitler
was in a hospital recovering from temporary blindness possibly caused by a
poison gas attack.
