 The tsar had given orders that he should not be allowed to speak to any other prisoners or guards; that he was to be kept there even after his sentence expired; and that his family was to remain unaware of his fate.Further, most of the commanders of the Shlisselburg prison were to be unaware of the exact identity of the prisoner.One of the few people who, at that time, managed to exchange - literally - a few sentences with Łukasiński, was Russian revolutionary Mikhail Bakunin, who was also imprisoned in Shlisselburg for several years.
