Karl Wagner is a disgruntled middle-aged instructor at the Bundeswehr Command and Staff College. He finds himself concerned about the direction which the German nation is headed in—just as he is killed by a terrorist attack. Only to awaken and find himself reborn as an infant, Bruno von Zehntner, the youngest son of a noble family renowned for its part in the German war industry a few years after the founding of the German Empire. Bruno, as he is now known, desires to rewrite history and ensure the German Empire emerges victorious in the coming century. And in doing so, finds himself entrenched in a world filled with Blood and Iron!
The commander of the Serbian Army sent with orders of "fighting until the last man" in order to buy time for a victory in the south against the Hellenic Army was more or less committing treason. His objective was to negotiate a peaceful surrender with the Germans, not only for his own men, but for all of Serbia.
He knew he wasn't exactly in a position to do so, and he also knew that Serbia, or more specifically its royal family in conjunction with the Black Hand, was guilty of a great many crimes. Crimes against not only the Habsburgs, but Bruno personally, as well as many innocent people in the Balkans.
At the end of the day, there was nothing he could really do to make amends for these sins. All he could do was ask for more peaceable terms than total annihilation by giving the enemy a show of good behavior.
