CHAPTER X

THE WAR IN 1916

"They Shall Not Pass!"—Early in 1916 the Germans began a furious attack on the strong French position at Verdun. This point was a highly important one for the French, because if it were captured by the enemy, he could make flank attacks upon their adjoining lines and perhaps compel a general retreat. The Germans had long been massing materials and men for the greatest military offensive which the world had ever seen. Twenty thousand men were placed on each mile of the front for a distance of twenty-five miles, while hundreds of thousands more were held in reserve. Thousands of guns of all sizes were brought up for the attack. Under the command of the German crown prince, the German people and the whole world were to be shown that the German army was still invincible.

Beginning on February 21, the titanic struggle around Verdun continued until July, when the attacks and counter-attacks were gradually suspended. In the early attacks the French were driven in from advanced positions, and then the Germans charged the heavily protected woodlands and hills. In massed formation they advanced in the face of artillery, machine-gun, and rifle fire of the heaviest character. The first waves were mown down like grain; but other troops, and still others climbed over the bodies of their dead comrades. Never since the world began had such slaughter been seen.

During the intervals between the infantry attacks the French troops were subjected to an unprecedented artillery fire. Suffering under a strain such as armies had never hitherto known, the French patriots yet held true to their watchword,—"They shall not pass." General Pétain (pā-tăn´), in a stirring address, said to his entrenched heroes, "Courage, we'll get them!" ("Courage, on les aura!"), and this phrase became the Verdun battle-cry. Try as the Germans would, from every possible point, they could not break through the living wall of Frenchmen. A little ground was won here and there, but before the end of the year nearly all had been retaken by the French. At a frightful cost the German crown prince and his military advisers had put their fighting machine to the test, and it had failed. A half million men, killed, wounded, or prisoners, were lost to the Germans before they ceased their attacks at this point.

The Battle of the Somme.—In July, 1916, while the Verdun struggle was still undetermined, the French and British troops began an advance on the German line along the river Somme (som). Exceedingly heavy artillery attacks first battered down the enemy defenses, and then the infantry went "over the top." During the long course of the Battle of the Somme (July 1 to November 17) the Allies advanced on a front of twenty miles to a maximum depth of about nine miles. Slowly, and at great expense of ammunition and men on both sides, the Allied progress had been won. They had failed to break through the German line, but they had shown how it might gradually be pushed back. And they had relieved the important position of Verdun from further severe attacks, because German forces were needed to the westward.

In the course of this battle, on September 15, the British first used their most original military machines—the "tanks." Thereafter these armored cruisers of the land were to play an increasingly important part along the western front.

Increased Use of Aircraft.—Aircraft, too, were every day becoming more valuable. In the first year of the war airplanes were used mainly for observation purposes: to find the location of enemy forts, trenches, troops, and batteries; and to direct the fire of the aviator's own batteries. Hundreds of photographs were taken by the airmen, rapidly developed, and within thirty minutes the staff officers could be seen studying them with microscopes to determine what changes had taken place within the enemy's lines. Anchored balloons, too, were used for similar purposes.

Airplane construction and use developed more rapidly than any other feature in the war. After the observation machines, came the battle-planes, whose first purpose was to clear the way and protect the observation planes. Later, heavy machines for bombing expeditions were constructed; and squadrons of airplanes now took part in every battle, preceding the attacking party, and firing with machine-guns and bombs upon the enemy's trenches or his massed troops back of the line.
