All this was the work of the submarine.
One smiled twenty-five years ago when he read that highly imaginative story of Jules Verne, "Twenty Thousand Leagues Under the Sea," and wondered if it would ever be possible for man to create such a marvelous underseas craft as that which the famous French writer described. Today the imaginative detail of the submarine which the novelist described has been crystallized, and the world has learned that dreams sometimes come true.
Marvelous things have been developed by the war which is involving the peace and security of the world, but no single device has had such an effect upon the warfare and upon the methods of waging it as the diabolical submarine, which, like an assassin in the night, sneaks upon the great ships along the water highways of the world and sends them with their human freight to the bottom of the ocean.
TORPEDO'S DEADLY WORK.
A giant cigar-shaped missile, whose nose is pointed with guncotton and filled with high explosives—and which the world knows as the torpedo—launches forth from the submarine, and speeding under the drive of a propeller at the stern steers its way into the side of the battleship or great steamship. The torpedo plunges into the bowels of the vessel. There is a tremendous explosion, and the water-tight compartments of the vessel are torn open; the boat fills, and the pride of the seas is no more.
Had the vessel's master and her crew any warning? No; unless the vigilant officer on the bridge should note a thin pole with a hooked end projecting above the surface of the ocean some miles away, and turning his glasses upon it discover that it is the "eye" of a submarine—the periscope—which is protruding above the surface. Then he may turn his larger vessel and ram the submarine, or change the course of his craft so that the torpedo launched by the submarine will miss its mark, or perhaps expert gunners may turn the muzzles of their rapid-fire guns upon the underseas craft and riddle it before it can get far enough below the surface of the water to make the attack upon it futile.
EFFICIENCY OF THE SUBMARINE.
The enormous inroads on the world's shipping made by German submarines during the war shows the efficiency of this diabolical device. In the first two years and a half of the war statistics were compiled to show that more than 10 per cent of the world's merchant marine was destroyed by Germany's underseas craft of the U-boat type. Incidentally, the name U-boat as applied to submarines developed because Germany, instead of naming these slinking boats, as is the custom with surface-cruising vessels, painted upon the conning tower or nose of the craft the letter U, representing the word "underseas," coupled with the numeral denoting the number of the boat. Thus those who sail the ocean highways came to recognize the fact that a conning tower or low, sharp-nosed craft bearing the mystic characters U-9 was a German underseas boat No. 9.
The statistical records at the end of April, 1917, showed that nearly 3000 vessels of almost 5,000,000 gross tons were destroyed by the U-boats in the war. More than half of the vessels sunk belonged to England. Norway and France were the next greatest sufferers from the submarine warfare. In one week after Germany announced her intention to give no quarter, but to sink any vessel which came within the range of the U-boat torpedoes, the toll of ships lost was more than 400,000 tons.
At the beginning of the war the submarine was to all intents and purposes a novelty—a boat of recognized possibilities, but existing very largely in the experimental stage. Its use was very largely ignored by naval men, although it was conceded that when properly developed it would prove a wonderful agency of destruction. The proud commanders of the great battleships, with their 10, 12 and 14 inch guns, which sent great shells miles across the ocean, looked down upon the little underseas boat, and applied to it the sobriquet of "tin sardine."
