Walther Heinrich Alfred Hermann von Brauchitsch (* October 4th 1881 in Berlin) is a Colonel General in the Wehrmacht. 1910-38 he was married to Elisabeth von Karstedt, with whom he had three Kids. Since September 23rd 1938, he's married to the much younger Charlotte Rüffer who happens to be a "two hundred per cent rabid Nazi". Maybe for this reason he got a dotation of 80,000 Reichsmark from the "Führer" for his divorce.
In the First World War he was a Staff officer. Although he made a career in Nazi Germany, he participated in conspiracies targeted at arresting the "Führer" as soon as he'd want to start an unwinnable campaign. This never happened, though. And after the victory over France, this opportunity seems gone.
In the Hierarchy, he's Oberkommandierender des Heeres (Supreme Commander of the Heer), directly under Adolf Nazi.
