The battle of Borodinó was not fought on a chosen and entrenched position with forces only slightly weaker than those of the enemy, but, as a result of the loss of the Shevárdino Redoubt, the Russians fought the battle of Borodinó on an open and almost unentrenched position, with forces only half as numerous as the French; that is to say, under conditions in which it was not merely unthinkable to fight for ten hours and secure an indecisive result, but unthinkable to keep an army even from complete disintegration and flight.
