F. Reineke was commandant of Kamchatka from about 1780 to 1784. According to Витер's История символов как история административного деления государства he was responsible for moving the territorial administration from Bolsheretesk to Nizhnekamchatsk. According to J.B.B. de Lesseps, Reineke resigned in 1784 "for reasons which I am obliged to suppress".
It was common for Siberian administrators to be venal. According to Forsyth's A history of the peoples of Siberia, the very first governor of Siberia, Matvei Gagarin, was hanged for fraud, nepotism, and selling offices; another governor in Irkutsk was relieved from office for gross corruption and replaced with his second, who was "vicious" and "ruthless".
Was Reineke guilty of the same old corruption and exploitation, or something worse? I'm skeptical that de Lesseps, a Frenchman, had any reason to suppress a story of Russian corruption.
