The Germans, on the whole, showed more original genius in military science, varying their methods of attack and defense according to circumstances, building trenches and dugouts which we never equaled; inventing the concrete blockhouse or “pillbox” for a forward defensive zone thinly held in advance of the main battle zone, in order to lessen their slaughter under the weight of our gunfire (it cost us dearly for a time); scattering their men in organized shell-craters in order to distract our barrage fire; using the “elastic system of defense” with frightful success against Nivelle’s attack in the Champagne; creating the system of assault of “infiltration” which broke the Italian lines at Caporetto in 1917 and ours and the French in 1918. Against all that we may set only our tanks, which in the end led the way to victory, but the German High Command blundered atrociously in all the larger calculations of war, so that they brought about the doom of their empire by a series of acts which would seem deliberate if we had not known that they were merely blind. With a folly that still seems incredible, they took the risk of adding the greatest power in the world—in numbers of men and in potential energy—to their list of enemies at a time when their own manpower was on the wane. With deliberate arrogance they flouted the United States and forced her to declare war. Their temptation, of course, was great. The British naval blockade was causing severe suffering by food shortage to the German people and denying them access to raw material which they needed for the machinery of war.
The submarine campaign, ruthlessly carried out, would and did inflict immense damage upon British and Allied shipping, and was a deadly menace to England. But German calculations were utterly wrong, as Ludendorff in his Memoirs now admits, in estimating the amount of time needed to break her bonds by submarine warfare before America could send over great armies to Europe. The German war lords were wrong again in underestimating the defensive and offensive success of the British navy and mercantile marine against submarine activities. By those miscalculations they lost the war in the long run, and by other errors they made their loss more certain.
One mistake they made was their utter callousness regarding the psychology and temper of their soldiers and civilian population. They put a greater strain upon them than human nature could bear, and by driving their fighting-men into one shambles after another, while they doped their people with false promises which were never fulfilled, they sowed the seeds of revolt and despair which finally launched them into gulfs of ruin. I have read nothing more horrible than the cold-blooded cruelty of Ludendorff’s Memoirs, in which, without any attempt at self-excuse, he reveals himself as using the lives of millions of men upon a gambling chance of victory with the hazards weighted against him, as he admits. Writing of January, 1917, he says: “A collapse on the part of Russia was by no means to be contemplated and was, indeed, not reckoned upon by anyone … Failing the U-boat campaign we reckoned
