Gottfried Heinrich Graf zu Pappenheim (May 29, 1594 – November 17, 1632) was field marshal of the Holy Roman Empire in the Thirty Years' War. After years of service to the German Catholic League, Pappenheim was fatally wounded at the Battle of Lützen, the same battle that claimed the life of Protestant leader Gustavus Adolphus of Sweden.
Gottfried Pappenheim was a famous cavalry commander during the Thirty Years' War, employed by the imperial armies of the German Catholic League. He led a famous cavalry force known as Pappenheim's Black Cuirassiers. He participated in the Battle of Breitenfeld, where he ignored the orders of Count Tilly and attacked the Swedish right flank, only to be repeatedly repulsed and finally broken by Johan Banér.
As in the history before Grantville arrived, Pappenheim was in the employ of Albrecht von Wallenstein, but the Battle of Alte Veste was altered due to the presence of the up-timers and their firearms. Pappenheim's life was actually extended by the arrival of the Americans, as the Battle of Lützen did not take place.
The following year, Pappenheim acted as an emissary from Wallenstein to establish an alliance with the NUS and subsequently helped to foil a terrorist action at a town-wide Christmas celebration in Grantville. Afterwards, he reluctantly agreed to dress as Santa Claus.
After reuniting with Wallenstein, Gottfried helped in their war against the Hapsburg dynasty and the Ottoman Empire. Shortly before the Second battle of the White Mountain, Wallenstein gave Pappenheim the title of Duke of Moravia.
