Still further perplexities arose about the laws of war. If the front was abolished, if civilians were to be bombed from the air, what became of the right of professional soldiers to shoot franc-tireurs and destroy their homes? It was as if the arena of a football match were invaded by the spectators, who began kicking the ball about, chasing the referee, and declining to keep any score as between the original sides in the game.
The military authority recoiled from these devastating riddles of the new age. Such issues, he decided, were not for him. There had always been sides in a war, and there must still be sides. It was for the politicians to define them. He fell back on his fundamental conception of a Power “imposing its Will” upon another Power, but using now, in addition to the old invasion and march on the capital, the new methods of propaganda, blockades and attacks behind the front, and all the latest chemical and aerial devices to “undermine the morale” of the enemy population and dispose its government to yield. In the end there must be a march, if only a concluding professional march, through the goal or capital of the losing side. He refused to entertain the inevitable problem of an enemy government not yielding but collapsing, and leaving no responsible successor. That was not his affair. Presumably in that case the war would continue indefinitely.
Nor was it his business to enter into the financial aspects of the matter, to estimate any ratio whatever between the costs of the New Warfare and the material advantages to be exacted when the Will of the conqueror was imposed. In that regard he was excessively modest. He could not be expected to think of everything. His business was to prepare the best and most thorough war possible, with all the latest improvements, and quite regardless of cost, for his Power. It was for his government to find out how to pay for and use the war he had prepared for it. Or to use it partially. War, just war itself, was the limit of his task.
Research for the latest improvements soon led the now almost morbidly progressive military mind to some horrifying discoveries. Some of the soldiers concerned were certainly badly scared by the realization of what evils it was now possible to inflict in warfare. It leaked out in their speeches and books. But they kept on. They kept on partly because they had a stout-hearted tradition and refused to be dismayed, but mainly no doubt for the same reason that the Christian priests and bishops who had lost their faith still stuck to their Churches — because it was the only job they could do. Throughout the three decades that followed the Congress of Versailles, thousands of highly intelligent men, specialist soldiers, air soldiers, engineering soldiers, chemical, medical soldiers and the like, a far ampler and more energetic personnel than that devoted to the solution of the much more urgent and important financial riddles of the time, were working out, with unstinted endowments and the acquiescence and approval of their prospective victims, patiently, skilfully, thoroughly, almost inconceivably, abominable novelties for the surprise and torture of human beings.
None of these experts seems to have been more than mediocre; it was an age of mental and moral mediocrities; and even within the accepted limitation we have already noted, none of them seems to have worked out the New Warfare as a whole complete process. Groups of men working in secrecy, immune from outer criticism, naturally conspire not only against the foreigner but against each other, and most of the men in decisive positions were rather men skilled in securing appointments and promotion than inspired specialists. A certain lumbering quality in their devices ensued.
In Great Britain a group of these experts became exceedingly busy in what was called mechanical warfare. The British had first invented, and then made a great mess of, the tank in the World War, and they were a tenacious people. The authorities stuck to it belatedly but doggedly. In a time of deepening and ever bitterer parsimony their War Office spared no expense in this department. It was the last of all to feel the pinch. The funny land ironclads of all sizes these military “inventors” produced, from a sort of armoured machine-gunner on caterpillar wheels up to very considerable mobile forts, are still among the queerest objects in the sheds of the vast war dumps which constitute the Aldershot Museum. They are fit peers for Admiral Fisher’s equally belated oil Dreadnoughts.
The British dream of the next definitive war seems to have involved a torrent of this ironmongery tearing triumphantly across Europe. In some magic way (too laborious to think out) these armoured Wurms were to escape traps, gas poison belts, mines and gunfire. There were even “tanks” that were intended to go under water, and some that could float. Hansen even declared (see The Last War Preparations, xxiv, 1076) that he had found (rejected) plans of tanks to fly and burrow. Most of these contrivances never went into action. That throws a flavour of genial absurdity over this particular collection that is sadly lacking from most war museums.
The British and the French experts, and presently the Germans, also worked very hard at the fighting aeroplane — the British and Germans with the greatest success; the aerial torpedo, controllable at immense distances, was perfected almost simultaneously by the Italians and the Japanese. The French mind, for all its native brilliance, was hampered by its characteristic reluctance to scrap old plant for new. It was the German, American and Russian experts who went furthest with the possibilities of chemical attack. The disarmament of Germany necessarily forced its military authorities to concentrate on an arm that could be studied, experimented upon and prepared unknown to the outer world, and the Russians were forced to take up parallel enquiries because of their relative industrial poverty. The Germans had been first to use gas in the Great War, and they remained for a long time the war gas pioneers. But after the Great War much attention was given to this arm in America through the influence of the chemical industry. Biological warfare, that is to say the distribution of infectious diseases, was also extensively studied, America and the Central Europeans in this case leading the way.
Even before the Central European fighting in 1940 and the subsequent years, the distribution of various disease germs was no longer a merely theoretical possibility. Little containers, made to look like fountain pens, were already being manufactured. The caps could be removed to expose soluble ends, and then they could be dropped into reservoirs or running streams. Glass bombs also existed for use from aeroplanes, railway-train windows and so forth, which would break on hitting water. There are specimens in the Aldershot Museum. The enrolment and territorial organization of medical men and trained assistants to inoculate threatened populations went on with increasing vigour after 1932.
But there was a certain hesitation about the use of disease germs. It is easy to distribute them but hard to limit their field of action, and if prisoners (military or civilian) were still to be taken and towns and territory occupied, a well launched pestilence might conceivably recoil with deadly effect upon its users. Bacterial warfare seemed, even to the specialists who studied it, a very improbable method for any but an heroically vindictive population in the hour of defeat. Nevertheless it was thought best to have it worked out. Except for the distribution of malignant influenza in Kan-su and Shensi by the Japanese during their efforts to tranquillize North China in 1936, “without proceeding to extremities”, its use was never officially admitted. Other alleged instances of its deliberate employment by responsible Powers have been shown by the researches of the Historical Bureau to have been due either to the unauthorized zeal of subordinates or to the activities of those religious fanatics who became so prevalent during the period of confusion after 1945. The acclimatization of the mosquito transmitting yellow fever in India in 1950, which did so much to diminish the population of that peninsula, has never been explained. It is generally supposed to have been accidental.
So far as method and invention went, what was called “Gas Warfare” ran very parallel to bacterial warfare. Its beginning and end is now a closed chapter in the history of the human intelligence and will. It is surely one of the strangest. It set its stamp upon the clothing and urban architecture of the age. It ranks in horror with the story of judicial torture or the story of ritual cannibalism, but its inhumanity is more striking because of its nearness to our own times. Like those older instances, it brings home to us the supreme need for sound common general ideas to hold together human activities. It tells how thousands of clear and active minds, each indisputably sane, could, in an atmosphere obsessed by plausible false assumptions about patriotic duty and honour, cooperate
