"How the Russian GULAG prisoners who were working day and night "
I deny that the bulk of Gulag prisoners were Russian.
If you have statistics, pls advise but based on the most recent info ( and not from the Russophile Solzeniyshen) the vast majority of prisoners were not Muscovy.
"I deny that the bulk of Gulag prisoners were Russian. "
From Anne Applebaum "Gulag a History", Chapter The Prisoners. She spent many months researching the Gulag archives, interviewing the survivors in Russia, Ukraine, Belarus, Baltics, Poland, etc.
"Odd things it sounds, in most camps there was no clans for Russians, the ethnic group which formed the decided majority in the camps, according to the Gulag's own statistics, throughout their existence. Russians did, it is true, attach themselves to one another according to what city or part of the country they came from, Muscovites found other Muscovites, Leningraders other Leningraders and so on."
