But the ancient maxim lasted, in spite of this better example, throughout the seventeenth and till late into the eighteenth century, for we find Vattel even then thus protesting against it: ‘How could it be conceived in an enlightened age that it was lawful to punish with death a governor who has defended his town to the last extremity, or who in a weak place had the courage to hold out against a royal army? In the last century this notion still prevailed; it was looked upon as one of the laws of war, and is not even at present totally exploded. What an idea! to punish a brave man for having performed his duty.’[132] But not even yet is the notion definitely expunged from the unwritten code of martial etiquette. The original Russian project, submitted to the Brussels Conference, proposed to exclude, among other illicit means of war, ‘the threat of extermination towards a garrison that obstinately holds a fortress.’ The proposal was unanimously rejected, and that clause was carefully excluded from the published modified text! But as the execution of a threat is morally of the same value as the threat itself, it is evident that the massacre of a brave but conquered garrison still holds its place among the laws of Christian warfare! This peculiar and most sanguinary law of reprisals has always been defended by the common military sophism, that it shortens the horrors of war. The threat of capital punishment against the governor or defenders of a town should naturally dispose them to make a conditional surrender, and so spare both sides the miseries of a siege. But arguments in defence of atrocities, on the ground of their shortening a war, and coming from military quarters, must be viewed with the greatest suspicion, and, inasmuch as they provoke reprisals and so intensify passion, with the greatest distrust. It was to such an argument that the Germans resorted in defence of their shelling the town of Strasburg, in order to intimidate the inhabitants and drive them to force General Uhrich to a surrender. ‘The abbreviation,’ said a German writer, ‘of the period of actual fighting and of the war itself is an act of humanity towards both parties;’[133] although the savage act failed in its purpose and General Werder had to fall back, after his gratuitous destruction of life and property, on the slower process of a regular siege. If their tendency to shorten a war be the final justification of military proceedings, the ground begins to slip from under us against the use of aconitine or of clothes infected with the small-pox. Therefore such a pretext should meet with prompt condemnation, notwithstanding the efforts of the modern military school to render it popular upon the earth.
