The terror of the road, armored with 6-inch Krupp steel, shell-proof, carrying 120 men and two 4.7-inch quick-firers; speed 25 miles per hour.] Rank by rank, company by company, regiment by regiment, weapons of death at their sides, messages of death in their cartridge belts, thoughts of death in their hearts, they passed, all dressed in the earthly iron-gray which betokened that the death they gave they would have to face and that it were well to be as protectively concealed as possible. Rank by rank, company by company, regiment by regiment, the sun glinting on their field equipment, the sun burning the frames already wearied by the march from garrisons in Germany, the sun waiting to turn the slain bodies of those marching men to sights of which a soldier even fears to dream, years after the war is over. By tens, by thousands, by tens of thousands they came. The details of organization were incredible. Waiting for each column to pass were men with buckets of drinking water into which the men dipped their aluminum cups. Temporary field post-offices were established so that messages could be gathered as the armies passed and forwarded back to Germany. Here and there men passed out handfuls of biscuits and prunes. The infantry strode through in heavy marching order, many of them lame and footsore, heads and beards shaved under the spiked helmets, bearing the look of bestial stolidity which is the inseparable result of the deliberately brutalizing German discipline. Two trucks passed by with cobblers at work on the march. When a soldier's shoes wore out on the road, he dropped out of rank, mounted the running board of the cobbler's truck until he received back his foot-gear, mended. Machine-gun companies accompanied the infantry, sprinkled with a few quick-firers of 2.6-inch caliber, easy to man-handle in action, firing 15 shots a minute. Secondary batteries of this arm also accompanied the heavy artillery. Behind the infantry came the field artillery, in which, at this time, the German Army was weaker than the armies of the other powers. The field gun was the .96NA, corresponding closely to the British 15-pounder which had been discarded, save for the Territorial Army. It could not be compared to the famous French "Soixante-Quinze," the most marvelous of all field-guns, with a 2.9-inch (75 mm.) caliber and the most mobile weapon known.[8] On the other hand, the light field howitzers of 4.1-inch caliber and the heavier field howitzers of 5.9-inch caliber were far in advance of those of any other army. They were modern, formidable and admirably handled. This 5.9-inch howitzer shared with the French "Soixante-Quinze" the dubious honor of being the most death-dealing weapon of the war.
