Saloniki now being an incident of her military past, the next plan of her staff was an effort on Verdun, the great fortress which occupied a salient in the French siege line. Here, as elsewhere when she attacked, she concentrated both her own and the Austrian heavy artillery, and following the system of intense artillery preparation, threw in her waves of infantry. This blow was struck at the most inclement season of the year, in February snow and slush and rain, as if to anticipate the allied attack which was generally thought bound to come later in the spring when sufficient munitions had been accumulated on the western front and the weather was favorable.
By this time experts who had thought the war would be decided in the Balkans had again realized that it never pays to desert the simple military principle that the decision comes between the main bodies of armies and not in remote regions from any clash of subsidiary forces.
Paris or Petrograd in the hands of the Germans might mean such a decision. Certainly, should the western front be broken by either side, it would be the most telling blow of the war in both the moral and the military sense. But after all, was the line of least resistance for Germany the line of the western front? Would she really strike her great blow of 1916—if she still had the power to strike one—against the western rather than the eastern front? Hitherto, attacks had succeeded against Russia.
It was in Russia that she had had her success. German officers had always stated their confidence that with their superior gun fire and tactics they could always force the Russians back. Could they press back the French and the British?
When would the war end? seemed as unanswerable to the lay observer in the spring of 1916 as in the spring of 1915. How long was the fearful attrition to go on? Could either side ever strike a decisive blow, or would the eventual result be a bloody stalemate, with England still in command of the sea?
The significant generic lesson of the war is not in the power of artillery, but the power of all material organization, when nations set out to gain their ends by force: its military lesson was that both sides had pretty well followed sound policy considering the situation, despite armchair critics who knew nothing of inside facts.
Europe was spending $100,000,000 or more a day in the business of destruction—of life and of property. A broad belt of ruins spread across France and Belgium for 450 miles; a broader one of 1,000 miles across Galicia and Russia. No nation engaged could be said to be victorious except the Japanese. Japan had gained Kiao-chau; strengthened her influence in China enormously, and was making immense profits by working her arsenals and every plant at full speed making munitions for Russia.
The United States at peace, preparing to make munitions as fast as she could, and able to produce only 3,000 rifles a week for the Allies on the 1st of December, 1915, and 5,000 a week March 1, 1916, was enjoying an era of "boom" prosperity, thanks to the eager market of nations whose own production was arrested while their workers were at war. From the gloom of London and Paris, where men and women had given up all luxuries, the transatlantic voyage brought you to New York, which was the only gay capital in the world, enjoying all the privileges of extravagance when money is plentiful.
WAR BY MACHINERY
This has been a war of machinery; but the old rule has been true that development in any weapon of offense has been countered by further development of means of defense. Nor is the theoretical power of weapons ever equaled by their actual power when the test of war comes. With self-preservation remaining the first law of nature, man is in nothing so skillful as in avoiding the enemy's blows.
When one watches a 15-inch gun fired and hears its 2,000-pound shell go screaming through the air, his concept of its destructive action is exaggerated by imagination, and further confirmed if he sees that shell burst inside a house, reducing its interior to wreckage. But the shell may not hit the house; it may fall in an open field and merely make a crater in the earth. Besides, someone must be in the house when it is hit if there are to be any casualties; and it is quite possible that a single person present might be dug out of the debris unharmed. Vulnerable as man's flesh is, he remains a pretty small object on the landscape. If he knows that his house is in danger of being struck he then either goes into the cellar at the first alarm, after having covered his floor with sandbags, or he may take to a dugout in his yard.
When one has seen ten 15-inch shells strike a town of 25,000 inhabitants in a busy hour of the day and only half a dozen persons killed and injured, he may learn a contempt for shell fire which, however, is promptly turned into a tragic respect when one of the same sort of shells strikes in a stone-paved courtyard where a hundred soldiers are at their evening meal, and two-thirds of them are killed and wounded.
The bursting of a shrapnel shell and its spray of low-velocity bullets is also theoretically most destructive, but a roof of 6-inch boards will furnish perfect protection from the bullets. Mother Earth remains the best protection there is from fire. No rifle bullet can penetrate through a 3-foot thickness of sandbags. A 6 or 8-inch high-explosive shell, which is the largest caliber practicable for trench warfare, may burst near a double layer of bags of stone rubble without hurting anyone in a cellar 30 feet underneath. The rain of shrapnel bullets which mows the barbed wire in front of a trench, as hail mows ripening grain, will not reach a single man in the trench to the rear, if he keeps his head down.
At first thought it seems utterly inconsistent when bullets carry effectively a mile and a half, and guns carry twenty miles, that infantry should be fighting so close that they can throw bombs at each other from distances of 15 and 20 yards. The very destructiveness of modern weapons has contributed toward this result.
There has never been anything like so many guns used in battle, and never have they been capable of such rapid fire. The field gun can fire consistently eight or ten shots a minute, thanks to its modern recoil cylinder and to the steadiness of aim, and literally establish a "curtain of fire" with its torrent of bullets shot down from the air and the cataracts of earth shot up by the bursting of high-explosive shells in the ground, which no infantry can pass.
A machine gun behind a shield firing 500 shots a minute is practically safe from rifle fire, and soldiers intrenched on either side of it add to its volume their own more accurate fire from their rifles. Infantry in the open, though they were not subjected to the fearful concentration of artillery fire, could not survive through a mile of machine-gun and rifle-swept space. Successful advances against anything but very inferior numbers badly armed become impossible in any frontal attack in the open. Thus all modern infantry operations must have more or less a siege character, as the only practicable means of approach is by digging your way forward. The spade has become almost as important a weapon as the rifle.
Impatience with digging, which was characteristic of the early days of the American Civil War, and which has been generally resented by all armies in the past, has now become second nature to every soldier, because its value is brought home to him by the most telling kind of lesson in experience—death. He puts earth between himself and the enemy's fire as instinctively as one holds up his hand to ward off a blow.
In trench fighting all that is exposed of a man firing is his head and shoulders, which accounts for the high percentage of dead to wounded in this war. In other wars it has been as one to five; while in this war, on the western front, it has varied from as one to two and three. If the trenches are brought extremely close together then either side is safe from the other's artillery fire, because there is as much danger of hitting your own trench as the enemy's with your shells. A distance of 20 or 30 yards meant that at any time either side could start in throwing bombs or grenades by hand across that one definitely neutral country—the zone of death between the trenches. Beyond that range up to the average range, trench mortars which "lobbed" a charge of high explosive from trench to trench could be used. Thus the war of machinery became a war of explosives. Anything that could be dropped into the trench and burst might kill or wound some of the enemy, which meant debit on their side of the ledger in a war of attrition and exhaustion. The higher the angle of flight the more likely the charge actually to fall into the narrow ditch in the earth, instead
