Figes 1997, p. 258:quotes such comments from the peasant soldiers during the first weeks of the war: We have talked it over among ourselves; if the Germans want payment, it would be better to pay ten rubles a head than to kill people. Or: Is it not all the same what Tsar we live under? It cannot be worse under the German one. Or: Let them go and fight themselves. Wait a while, we will settle accounts with you. Or: 'What devil has brought this war on us? We are butting into other people's business.' Figes, Orlando (1997). A People's Tragedy: A History of the Russian Revolution. New York: Viking. ISBN978-0670859160.
Figes 1997, p. 419:"It was partly a case of the usual military failings: units had been sent into battle without machine-guns; untrained soldiers had been ordered to engage in complex maneuvers using hand grenades and ended up throwing them without first pulling the pins." Figes, Orlando (1997). A People's Tragedy: A History of the Russian Revolution. New York: Viking. ISBN978-0670859160.
