    var tolstoy1 = "The sole importance of the crossing of the Berëzina lies in the fact\n  that it plainly and indubitably proved the fallacy of all the plans for \ncutting off the enemy’s retreat and the soundness of the only possible \n line of action--the one Kutúzov and the general mass of the army \n demanded--namely, simply to follow the enemy up. The French crowd fled\n at a continually increasing speed and all its energywas directed to \nreaching its goal. It fled like a wounded animal and it was impossible \nto block its path. This was shown not so much by the arrangements it\n made for crossing as by what took place at the bridges. When the bridges\n broke down, unarmed soldiers, people from Moscow and women with children\n who were with the French transport,all—carried on by vis inertiea --\npressed forward into boats and into the ice-covered water and did not,\n surrender."

On the \ncontrary, I can supply you with everything even if you want to \ngive dinner parties,\" warmly replied Chichagóv, who tried by every\n word he spoke to prove his own rectitude and therefore imagined \nKutúzov to be animated by the same desire.\n\nKutúzov, shrugging his shoulders, replied with his subtle \npenetrating smile: \"I meant merely to say what I said.\""
