The caves described in the Arabian Nights are not more wonderful than the rock citadel of Verdun; in many ways they are not so marvelous. The old citadel is now like a deserted cave, but a cave lighted by electricity and with a passenger elevator to carry one from the lowest floor to the top of the rock, a hundred feet above. In former wars it was a hive of soldiers.

Blasted out of the solid rock-hill are rooms, great halls, passages, hospitals, storerooms, and barracks. The heaviest shells of the enemy fall harmless from the natural rock. Here, one would think, a few soldiers could hold the town and the Meuse valley against greatly superior numbers. And this would be true if it were not for the fact that modern long-range guns can be placed by an enemy on the surrounding hills, once they have won them, and prevent food, ammunition, or supplies being brought to the citadel. Leaving these guns with enough men to work them, the great body of the enemy could then advance towards Paris, for the Meuse valley at Verdun is the highway from Metz to Paris.

The French generals realized long ago that the city and the valley could not, because of the increased power of big guns, be defended from the citadel. So they built great forts several miles from the city upon the hills which surrounded it, to halt the Germans when they should advance, as France knew they would when they were ready.

For an army to get from Germany into France and to the plains east of Paris, it was necessary to pass down the valley of the Meuse and through Verdun, and for this reason France spent vast sums of money to make these forts impregnable.

After the opening weeks of the World War had shown how easy it was for the German big guns to destroy the finest modern forts, like those at Liége, Namur, and Antwerp, the French command removed the garrisons from the forts protecting Verdun and placed them in trenches farther away from the city and the citadel, upon the second range of hills.

There was another way for the Germans to reach the plains of Champagne and of Châlons, which by treaty they had agreed not to use. That way was through Belgium. When the Huns declared this treaty only "a scrap of paper" to be torn up whenever their plans required it, and, to the surprise of all honorable nations, went through Belgium, they were soon able to reach the plains east and north of Paris, and Verdun ceased to be a key position. Verdun was about one hundred and fifty miles from Paris, and the Germans were already less than half that distance from the city. So when it was learned that the enemy had determined to capture Verdun, the forts surrounding it, and the highway through the river valley, the French command decided it was not worth holding at the cost in lives that would be necessary. To capture it would help the Germans very little, and to retire from it would greatly improve the French lines.

The Germans doubtless realized that this would be the decision of the French and that they would have an easy, an almost bloodless, victory. They also knew that all Germans and all Frenchmen had for centuries looked upon Verdun as a second Gibraltar and as one of the chief defenses of Paris and northern France, one which had been made—as the French thought—impregnable by the expenditure of vast sums of money. For this reason the Germans believed its loss would be taken as a terrible blow by the French people, and would be considered by the German populace as the greatest victory of the war. They hoped it might be the last straw, or one of the last, that would break the backbone of the French resistance. In order to give credit for this great victory to their future Kaiser, the armies of the Crown Prince were selected for the easy task.

The French command, it is said, had already issued the first orders for the retreat to stronger positions, when the French civic leaders realized Germany's game by which she hoped to win a great moral victory and to add to the hopes and courage of the German people; and although General Joffre believed it was a mistake, the French decided to remain just where they were.

The Germans were so sure of everything going as they had planned that they had advertised their coming victory in every corner of Germany and even in the Allied countries. When they found they were to be opposed, they brought up larger forces and when these were not strong enough to win, they increased them, until the Battle of Verdun, in which the Germans lost nearly half a million men in killed, wounded, and prisoners, became probably the greatest battle in the history of the world. It continued for six months.

Is it not strange that this, the greatest of all battles, was not a conflict waged to secure some territory, some river crossing, some fort, or some city absolutely necessary to win further progress, but a battle to add strength to the German mind and soul and to weaken the spirit of the French? Think of these modern Huns, who believe in the force of might and of material things, fighting for a victory over the spirit, which is never really broken by such things and is never conquered by them, but is to be won only by justice, mercy, friendship, love, and other spiritual forces.
