Lessons of more limited significance have to do with the effectiveness of the submarine and the unexpected radius of action of which it has shown itself capable; the amazing destructive power of the torpedo; the value of the battle cruiser, both for the defense of a coast from raiding expeditions, and for operations in distant seas where speed is needed to bring an enemy to action, and heavy guns to insure his destruction; the difficulty of reducing shore fortifications by fire from ships; the necessity of aeroplanes for scouting at sea, and the modifications in naval strategy and tactics which will result from their general adoption.
After many months of sparring between the British and German naval forces in the North Sea, an important engagement took place on May 31, 1916, between the two main fleets. Exactly what forces were engaged will probably not be known until the end of the war, and it is certain that we must wait long for definitely reliable reports as to the losses on the two sides. It is already clear, however, that the encounter has added little to our knowledge of naval warfare. British battle cruisers engaged German battleships at close range and were badly punished. In this there was nothing new or instructive. Nor has anything new or instructive developed from what is thus far known of other phases of the battle. Indeed the one and only striking feature of the battle appears to be the fact that everything occurred practically as it might have been expected to occur. Neither submarines nor destroyers, neither Zeppelins nor aeroplanes provided any startling features. The only lesson thus far apparent is the old one that while dash and audacity have their place in warfare, they need the directing and steadying hand of judgment and of skill.
THE WORLD'S WAR
By FREDERICK PALMER
INITIAL STRATEGY
In innumerable volumes future generations will learn the details of this war: and the discussions among delving historians will never end. For our time a simpler task is the service set for us. We require a record of the essential facts of the struggle arranged with a sense of historical perspective.
For forty years the great nations of Europe had had universal service. Every able-bodied youth, unless his government chose to excuse him, became a soldier. For forty years the diplomatists had held the balance of power so delicately poised that the mighty armed forces all kept to their own sides of their frontiers. It was in the era of modern invention and man's mastery of material power that these great armies were formed and trained for the war that was to test their steel.
Where Napoleon marched a hundred thousand men along parallel roads, the modern general sends his millions on railroad trains. The problem for each nation when war came was to concentrate with a greater rapidity than its adversary its enormous masses of men and guns against the enemy; and success in this was not due as in former days to speed of foot over good highways such as the Romans and Napoleon built, but to organized railroad and automobile transport or rather the prompt employment of all the industrial resources of the nation for war alone.
Out of the conflicting reports day by day emerge to the observer as he reviews the progress of the war, with the map before him, plans of campaign as simple in their broad lines as in Cæsar's or Alexander's day. Generals fighting with a million or two million men under their command have held to the same principles as if they had only ten or fifteen thousand.
All schools of successful warfare have believed in the offensive; in quick decisive blows which take the enemy by surprise and find him unready if possible. They hold that the army in rest must always be beaten by the army which takes the initiative. This partly explains the frequent small actions indicated by the reports of trenches taken in assault along the western front, while the lines occupied by the armies did not radically change. Such actions are the natural expression by any spirited force of its sense of initiative. Unless you sometimes take some of the enemy's trenches, he will be taking yours. By striking him in one section you may prevent him from striking you in another. Von Moltke and the other great German generals were only following in the footsteps of Napoleon when they taught that the offensive should be the first thought of every soldier.
The offensive naturally seeks to flank its adversary. Lieutenant General Winfield Scott once stated that if two lines of men, without any officers, were placed in a field, one line would inevitably try to get around the end of the other. The immensity of the forces, the power and precision of modern armies in defense has lengthened the battle fronts from a mile or a mile and a half in Napoleon's time to hundreds of miles.
It is an old rule, that you cannot break through a battle front, which means that you are thrusting in a wedge which will draw fire on both sides. Pickett tried to break a battle front at Gettysburg. A frontal attack which was no less pitiful in its results was that of the Federals at Fredericksburg. Grant's hammering tactics against Lee succeeded only by the flanking operations of superior numbers.
Strategically, the situation of the Central Powers was extremely strong. Aside from the fact that their preparedness in numbers of trained men, in arms and material, is too well known for mention here, their excellent network of railways enabled them to make rapid concentration. They had what is known as the interior line, which gave Meade his advantage at Gettysburg. Whether the interior line is three miles or a thousand miles long does not affect the principle involved. Interior lines mean quick transportation of reserves from point to point in concentration. It does not matter whether their numbers are hundreds or hundreds of thousands; the advantage is intrinsically the same. Joffre had probably fifteen hundred thousand on the interior line of the Marne. Meade had seventy thousand at Gettysburg.
In keeping with all great plans that of the Central Powers was extremely simple. Austria was to look after Russia. She could mobilize more rapidly than Russia, and her army was counted upon to take the offensive into Russia and deliver a hard blow before the Russian was ready to receive her. Indeed, the Austrian was to attempt in the east what the German attempted in the west. The German army was confident that in any event the slowness of Russian mobilization would give it time for its daring venture in the west. As the French, too, had excellent railroad systems, they also would mobilize rapidly. The full strength of the German army, therefore, was thrown against the French and the little Belgian army of eighty thousand ill trained and equipped men in the first month of the war. By using their interior lines, striking first in the west and then in the east, the Germans were warranted on paper in counting on successes that might have ended the war within the first four or five months.
The frontier of France from Switzerland to Luxemburg, when manned by the large numbers of the French army, became a battle front. There was no room for a flanking operation. German ambition for a decisive and prompt victory over the French army must have room for a turning movement. The Germans made the invasion of Belgium a military necessity for their purpose, which was the destruction of the French army. They had built the great 17-inch mortars for smashing the Belgian fortresses in order to open the gate for the flood which was to sweep southward to Paris. These guns were less practicable for field work or even for trench work, being best against cities and stationary guns in forts.
Thus the German plan of campaign was fully developed the second day of the war. It was no longer a secret to the general public, let alone to the French staff, which recognized that it had to deal with this effort of the German wing to come through Belgium. A French movement into Alsace failed. The public reason given for this was that it was a political demonstration in raising the Tricolor over the "lost provinces" dear to the heart of every Frenchman. Another—a military reason—which would seem a more obvious one to the soldier, was a counteroffensive to draw off the force of the German offensive at Liege and Namur, hoping thus, at least, while Liege and Namur were holding the German right in position, to force the German left to the bank of the Rhine. If you will look at the map you will see that this strategy becomes transparently intelligible.
Thus early in August the French were trying to turn the German left, and the Germans were preparing to turn the French left. Had the Belgians had
