In 1937 German Field Marshall von Blomberg, Chief of Staff of the Wehrmacht, entered into a second marriage with his secretary, Erna Gruhn. Shortly afterward a police report surfaced that showed Frau Gruhn was an ex prostitute. Hitler fired him.
Colonel General Freiherr Werner von Fritsch was second in command and the logical officer to succeed him. Himmler's SS furnished paperwork showing that General Fritsch had entered a homosexual relationship with a man named Schmidt. A subsequent German Army courtmartial ruled that the SS paperwork was a pure frameup. Never the less, von Fritsch, and 16 other senior generals were retired. Forty five other German generals were transferred to less important posts.
This all comes from The Rise and Fall of the Third Reich, William Shirer.
In 2012 two top American generals were re leaved of duty following mysterious and suspicious charges.
