Heino Heinrich Graf von Flemming
Flemming was born in Martenthin into an old noble Brandenburg family that probably emigrated from the Netherlands. After a comprehensive education at German universities, Flemming fought the Ottoman Turks as a Colonel of Auxiliary Troops in the service of Brandenburg. Frederick William, Elector of Brandenburg, sent him to the King of Poland in 1672. After serving William of Orange excellently several times, Flemming eventually came to serve in the Brandenburg army, although in times of peace he served in other armies. Because of his ability and bravery he received many offers to change services, and in 1682 became a Feldmarschallleutnant (roughly the equivalent of a two-star general) in the Saxon army. Commanding Saxon auxiliary troops, he contributed to the delaying of the Turks before Vienna in 1683.
On 15 February 1684 he became commander of Saxon troops and became a Field Marshal after the death of Baron von der Goltz on 8 September 1688.
In this and the following year he commanded the Saxon troops on the Rhine under Elector John George III. However, he was suspended for multiple personal offenses, which hurt him deeply. The Austrian generals accused him of corruption. He left the Saxon army and became a marshal with the Brandenburg army, one of four field marhals who did so (the other three being John George II, Prince of Anhalt-Dessau, Derfflinger, and Spaen). Flemming commanded successfully in Flanders and retired in 1698 for health reasons.
Regarding personal names: Reichsgraf was a title before 1919, but now is regarded as part of the surname. It is translated as Count of the Empire. Before the August 1919 abolition of nobility as a legal class, titles preceded the full name when given (Graf Helmuth James von Moltke). Since 1919, these titles, along with any nobiliary prefix (von, zu, etc.), can be used, but are regarded as a dependent part of the surname, and thus come after any given names (Helmuth James Graf von Moltke). Titles and all dependent parts of surnames are ignored in alphabetical sorting. The feminine form is Reichsgräfin. Titles using the prefix Reichs- were those created before the fall of the Holy Roman Empire.
