The battle of borodino was not fought on a carefully picked and fortified position , with forces only slightly weaker on the russian side . after the loss of the shevardino redoubt , the russians fought on an open , almost unfortified position , with forces half the strength of the french , that is , in conditions in which it was not merely senseless to fight for ten hours and gain a drawn battle , but incredibly difficult to keep the army for three hours together from absolute rout and flight
波罗底诺战役并不是在一个选定的，设了防的阵地上进行的，也不是俄军的兵力仅仅稍弱于敌军，实际上俄国人由于失掉舍瓦尔金诺多面堡，不得不在一个开阔的，几乎没有防御工事的地带，兵力比法军少一半的情况下迎接波罗底诺战役，也就是说，在这样的条件下，不仅战斗十小时和打一场不分输赢的战役不可思议，就是坚持三小时而不使军队完全崩溃和逃遁也是不可思议的。
