Leo Tolstoy said this quote
“ But to us of a later generation...it is inconceivable that millions of Christian men should have killed and tortured each other, because Napoleon was ambitious, Alexander firm, English policy crafty, and the Duke of Oldenburg hardly treated. We cannot grasp the connections between these circumstances and the bare fact of murder and violence, nor why the duke's wrongs should induce thousands of men from the other side of Europe to pillage and murder the inhabitants of the Smolensk and Moscow provinces and to be slaughtered by them. ”
