It is impossible to head a chapter ‘The Laws of War’ without thinking of that famous chapter on Iceland headed ‘The Snakes of Iceland,’ wherein the writer simply informed his readers that there were none in the country. ‘The laws of war’ make one think of the snakes of Iceland. Nevertheless, a summary denial of their existence would deprive the history of the battle-field of one of its most interesting features; for there is surely nothing more surprising to an impartial observer of military manners and customs than to find that even in so just a cause as the defence of your own country limitations should be set to the right of injuring your aggressor in any manner you can. What, for instance, can be more obvious in such a case than that no suffering you can inflict is needless which is most likely permanently to disable your adversary? Yet, by virtue of the International Declaration of St. Petersburg, in 1868, you may not use explosive bullets against him, because it is held that they would cause him needless suffering. By the logic of war, what can be clearer than that, if the explosive bullet deals worse wounds, and therefore inflicts death more readily than other destructive agencies, it should be used? or else that those too should be excluded from the rules of the game--which might end in putting a stop to the game altogether? The history of the explosive bullet is worth recalling, for its prohibition is a straw to clutch at in these days of military revival. Like the plague, and perhaps gunpowder, it had an Eastern origin. It was used originally in India against elephants and tigers. In 1863 it was introduced into the Russian army, and subsequently into other European armies, for use against ammunition-waggons. But it was not till 1867 that a slight modification in its construction rendered it available for the destruction of mankind. The world owes it to the humanity of the Russian Minister of War, General Milutine, that at this point a pause was made; and as the Czar, Alexander II., was no less humane than his minister, the result was the famous Declaration, signed in 1868 by all the chief Powers (save the United States), mutually foregoing in their future wars by land or sea the use of projectiles weighing less than 400 grammes (to save their use for artillery), either explosive or filled with inflammable substances. The Court of Berlin wished at the time for some other destructive contrivances to be equally excluded, but the English Government was afraid to go further; as if requiring breathing time after so immense an effort to diminish human suffering, before proceeding in so perilous a direction.
