And the two must be the same: Hermann Christoph Friedrich, born 1765 in Wismar, died in Kristianstadt in 1818. One of your sources is assigning a wrong birthplace, birth date and death date to him.Bio: Kurt von Priesdorff. Soldatisches Führertum, Tiel 7: Die preussischen Generale von 1813-1820, ca. 1937, pp 113-115.
Or, if the latter lived from 1733 to 1806, was he made a general posthum[or]ously, and later even promoted further, in both the Swedish and Prussian armies ?
For Herman Friedric Christian, maybe he was born in Stralsund and lived from 1733-1806. I don't know.
PS. According to Priesdorff, Engelbrechten was promoted a Swedish general major on 14 January 1812.
