SEA-POWER AND THE BLOCKADE
 ONE of the most significant events at the very opening of the war was one of the quietest and least known. The
British Grand Fleet was collected in the waters of the North Sea in anticipation of trouble, not so much
because the British wished to fight as because they knew that part of the German plans involved a dash upon
England. Each captain had in his possession a sealed envelope of orders, to be opened only after receipt of a
certain signal. When it became clear that the war was a fact, the Admiralty sent out several hundred messages
by wire to various ships, each of them consisting of a single word, "GO"; within an hour the exact number of
replies came back, "GONE." No greater promptitude of action was displayed during the war. No more
extraordinary case is known in history.
Sea-power had in past wars proved the decisive factor. Napoleon was defeated by the British navy; sea-power
decided the American Civil War; and it was clear that the influence of sea-power in this war might also be
decisive. As a matter of fact, it was. The British navy silently, quickly, without fighting a major battle, in
a sense won the war.
The war was really won by a good many factors, not one of which could have been omitted. Thus, the Belgians in
their first resistance saved France and therefore won the war; the French in the battle of the Marne threw
back the Germans and decided the issue of the war; at the same time the Russians, by
 sacrificing their army in Poland, compelled the Germans to send troops east, and this allowed the French to
win the battle of the Marne. The coming of the British army and of the American army were both events without
which the war could not have been won; but, in a real sense, all of these must have failed but for the
blockade established by the British fleet.
The great weakness in the German position, the very thing the Germans were fighting the war to correct, was
their lack of raw materials necessary for German industry in peace or war. Nor could they collect in time of
peace a sufficient store of cotton, wool, rubber, and copper without advertising their intention to fight a
war. Some months' supply they might have on hand when the war broke out, but not more. A time would come,
therefore, when it would be extremely difficult for them to get along without new supplies or without changing
entirely their whole basis of living. They knew that if the British joined the war they would at once blockade
Germany and stop the stream of supplies from outside.
It meant a complete transformation of German industry. Everything in Germany would have to support the war,
because Germany would have to make everything she needed. Nothing should be made that the Germans could not
themselves use, for otherwise it could not be sold and would therefore become waste. Substitutes they thought
they could find for some things; enough supplies of others they thought they could smuggle through the British
blockade with the help of the Dutch, the Danes, and the Swedes, who could claim rights, as neutral countries,
to import such things for their own use, and who would then of course ship them to Germany. At any rate, the
Germans thought their army would win the war before this economic pressure created by the sea-power could
cripple them enough to bring the war to an end,
 They might have to get along without some things, eat food they did not particularly like, but there would be
enough to eat and to wear and to fight with, and the end would be glorious. The British should be made to pay
when the war was over.
The Germans thought it possible, however, that they might forestall the blockade. Their own fleet should slip
out before the British fleet sailed, and once on the open ocean it could give the British a
chase—perhaps meet and defeat them. It would get its food and coal from the United States and other
neutral countries; and by dividing the British fleet prevent the blockade of Germany. Fast German ships should
be also equipped to capture British merchant vessels, and they would thus reduce the stream of supplies going
to England, which was no less dependent than Germany upon raw material from outside if she was to continue the
war. It might be that they could in this way, by these commerce raiders, sink enough ships to make a
Then there were the submarines. They should attempt to sink battleships and thus break the blockade; sink
transports carrying troops across to France, steal into British harbors and sink the ships at anchor. If
German ships could not sail the seas, it would then become a simple thing to loose thousands of floating
mines. They would float along below the surface and, if a ship should touch one of them, it would explode and
sink her. They would be carried by the tides and currents down upon the British fleet and sink it.
Everything depended for the British upon the successful work of the fleet. It must keep open the ocean so that
the supplies could reach England on which the continuation of the war depended. The food of the British
people, clothes for the soldiers, everything necessary for the war, depended upon the British merchant marine
and the ability of the fleet to protect it against
 German cruisers, submarines, and mines. The whole issue of victory depended upon the adequacy of the work of
At the outset the British were too quick for the Germans. The famous order described at the beginning of this
chapter sent the British into action just in time to prevent the German escape. The German fleet was bottled
up in its own ports before the war really began. There were a few German warships in Pacific and South
American waters. Several German merchant ships were transformed into commerce raiders and for some months
these were able to elude the vigilance of British and Japanese ships sent in pursuit. The Emden had a
particularly thrilling and adventurous career.
But by Christmas of 1914 the German warships had been captured and sunk, and all commerce raiders had been
rounded up. Meanwhile, the great harbors had been protected and a steel net had been erected across the mouth
of the Thames River strong enough to resist submarines. This was a great engineering undertaking and its
success meant much. Similar nets were created at once for the other British harbors, and one was even built
practically across the Channel so as to stop mines floating down into the passage between England and France.
These nets were composed of movable sections which could be opened at will. It became necessary—such was
the cleverness of the Germans—to change the passage through the nets very often, because submarines
would be waiting to sneak through the moment the net was opened at the former spot.
Thousands of British ships were transformed into mine-sweepers to clear the sea around the British Islands, a
very dangerous and difficult work. Patrol boats to watch for submarines were sent out by dozens and then by
hundreds. A screen of destroyers steamed up and down in front of the Grand Fleet practically
 throughout the duration of the war to ward off submarines and raiders. Week after week, month after month, the
steady patrolling went on. The work of the submarine in sinking ships on the open ocean we shall have to tell
about as the story goes on, but the success of the British fleet was complete. The entire British army,
millions of men, was transported back and forth to France, practically without the loss of a man. Never for a
moment was the army in France, or the French army (also dependent upon the British navy), without food,
clothes, or ammunition, because of lack of transport. Despite the enormous number of ships sunk during the
course of the war by the submarines, the British factories never stopped work, night or day, because of a
failure of raw materials with which to continue.
In Germany, on the other hand, the blockade was so successful that things went from bad to worse. As the war
grew longer, the measures which the Germans had originally invented to create substitutes or to reorganize
industries became less and less adequate. While probably few actually died of starvation, civilians, and even
soldiers, were wearing clothes and shoes made of paper, and were not getting enough fats and sweets to keep up
health. The war came to an end with the German army beaten and practically in flight. It could hardly have
been brought to that situation without the pressure of the blockade. The work of the British fleet was one of
the most important single factors in winning the war.
