This was shown in the wild reaches of the Forest of the Argonne. There the machine-gun nests of the Germans were isolated and demolished speedily. Small parties of Germans were stalked and run down by the relentless Americans. On the other hand, the Germans could make no headway against the American troops operating in the Forest. The famous "Lost Battalion" of the 308th United States Infantry penetrated so far in advance of its supports that it was cut off for four days without food, water or supplies of munitions in the Argonne. The enemy had cut its line of communication and was enforced both in front and in the rear. Yet the lost battalion, comprising two companies armed with rifles and the French automatic rifle known as the Chauchat gun, called by the doughboys "Sho Sho," held out against the best the overpowering forces of the Germans could send against them, and were ultimately rescued from their dangerous position.
The training of the Americans was also in modern efficiency that made America prominent in the world of industry. The reduction of the German salient at St. Mihiel was an object lesson to the Germans in American methods. General Pershing commanding that operation in person, assembled the newspaper correspondents the day before the drive. Maps were shown, giving the extent and locale of the attack. The correspondents were invited to follow the American troops and a time schedule for the advance was given to the various corps commanders.
In that operation, 152 square miles of territory and 72 villages were captured outright. For the reduction of the German defenses and for the creeping barrage preceding the American advance, more than 1,500,000 shells were fired by the artillery. Approximately 100,000 detail maps and 40,000 photographs prepared largely from aerial observations, were issued for the guidance of the artillery and the infantry. These maps and photographs detailed all the natural and artificial defenses of the entire salient. More than 5,000 miles of telephone wire was laid by American engineers immediately preceding the attack, and as the Americans advanced on the morning of the battle, September 12, 1918, 6,000 telephone instruments were connected with this wire. Ten thousand men were engaged in operating the hastily constructed telephone system; 3,000 carrier pigeons supplemented this work.
During the battle American airplanes swept the skies clear of enemy air-craft and signaled instructions to the artillery, besides attacking the moving infantry, artillery and supply trains of the enemy. So sure were the Americans of their success that moving-picture operators took more than 10,000 feet of moving picture film showing the rout of the Germans. Four thousand eight hundred trucks carried food, men and munitions into the lines. Miles of American railroads, both of standard and narrow gauge, carrying American-made equipment, assisted in the transportation of men and supplies. Hospital facilities including 35 hospital trains, 16,000 beds in the advanced sector, and 55,000 other beds back of the fighting line, were prepared. Less than ten per cent of this hospital equipment was used.
As the direct consequence of this preparation, which far outstripped anything that any other nation had attempted in a similar offensive, the Americans with a remarkably small casualty list took 15,188 prisoners, 111 guns, many of them of large caliber, immense quantities of munitions and other supplies, and inflicted heavy death losses upon the fleeing Germans.
Two selective service laws operated as manhood conscription. The first of these took men between the ages of twenty-one and thirty-one years inclusive. June 5, 1917, was fixed as registration day. The total number enrolled was 9,586,508. The first selective army drawn from this number was 625,000 men.
The second selective service legislation embraced all citizens between the ages of 18 and 45 inclusive, not included in the first draft. Over 13,000,000 men enrolled on September 12, 1918.
The grand total of registrants in both drafts was 23,456,021. Youths who had not completed their 19th year were set apart in a group to be called last and men between thirty-six and forty-five were also put in a deferred class. The government's plan was to have approximately 5,000,000 men under arms before the summer of 1919. The German armistice on November 11th found 4,000,000 men actually under arms and an assignment of 250,000 made to the training camps.
A most important factor in the training plans of the United States was that incorporated in the organization of the Students' Army Training Corps, by which 359 American colleges and universities were taken over by the government and 150,000 young men entered these institutions for the purpose of becoming trained soldiers. The following are the conditions under which the S. A. T. C. was organized:
The War Department undertook to furnish officers, uniforms, rifles, and equipment, and to assign the students to military duty, after a few months, either at an officers' training camp or in some technical school, or in a regular army cantonment with troops as a private, according to the degree of aptitude shown on the college campus.
