Until and at the start of World War One, Adolf Hitler was a reserved Austrian who enlisted as patriot in the German army. Content to rise no higher then lance corporal, he was dutiful and reserved, accepting the poor conditions and risks at the front, where he was a dispatch runner. Injured during a poisoned gas attack, he was sent to a psychiatric ward, but his syndrome was then still considered a medical mystery at best, just cowardice at worst. It's argued that this trauma and neurological damage may have triggered his personality switch. Afterward, he became a political animal, extrovert and power-hungry, out for bloody revenge on the alleged enemies of the German people.
