Indemnity, which enables a state to conduct war at the enemy’s expense instead of its own, was a secondary object laid down by Clausewitz. His third was the winning of public opinion, which is accomplished by “gaining great victories and possession of the enemy’s capital” and which helps to bring an end to resistance. He knew how material success could gain public opinion; he forgot how moral failure could lose it, which too can be a hazard of war.
