When not to obey

„Sir, the King of Prussia has made you an officer of the Prussian Army, so that you know when not to obey an order!“ Prince Friedrich Karl to a Major in the Prussian Army (1870)

„ … in those cases, in which the junior-officer comes to the conclusion that his commander is no longer in a position to judge the situation, and where his order has been rendered inadequate by events, it is the expressed responsibility and duty of that junior-officer to either redefine or ignore the order.“ Prussian officer training manual of 1906
