Question 1. Sources A and B give different figures for the amount of Russian soldiers killed in the First World War. How can this be explained?
Leon Trotsky wrote source A for his book ‘The history of the Russian Revolution’ in 1932. It is a short paragraph from the book explaining how the Russian army lost more men than any other country in the war.
Source B was written by John Traynor for his book ‘Europe 1890-1990’ in 1991. The source is a simple table displaying Russian casualties and total mobilised units in the First World War. When comparing the two sources you notice there is a difference of 800,000 casualties.
