CHAPTER XXI

The War Under the Sea

Britannia rules the waves.--Enter the submarine.--The blockade of
Germany.--The sinking of the Lusitania and other ships.--The trade in
munitions of war.--The voyages of the Deutschland.--Germany ready for
peace (on her own terms).--The reply of the allies.--Germany's amazing
announcement.--The United States breaks off friendly relations.

You will remember how hard the Germans had worked, building warships,
with the hope that one day their navy might be the strongest in the
world. At the outbreak of the great war in 1914 they were still far
behind England in naval power. On the other hand, it was necessary for
the English to keep their navy scattered all over the world. English
battleships were guarding trade routes to Australia, to China, to the
islands of the Pacific. The Suez Canal, the Straits of Gibraltar, the
Island of Malta--all were in English hands, and ships and guns were
needed to defend them.

The German navy, on the other hand, with the exception of a few
cruisers in the Pacific Ocean and two warships in the Mediterranean,
was gathered in the Baltic Sea, the southeastern part of the North
Sea, and the great Kiel Canal which connected these two bodies of
water. It was quite possible that this fleet, by making a quick dash
for the ports of England, might find there only a portion of the
English ships and be able to overwhelm them before the rest of the
English navy should assemble from the far parts of the earth.

Winston Churchill, whose name you have read before, had the foresight
to assemble enough English vessels in home waters in the latter part
of the month of July, 1914, to give England the upper hand over the
fleet of Germany. As a result, finding the British too strong, the
Germans did not venture out into the high seas to give battle. A few
skirmishes were fought between cruisers, then some speedy German
warships made a dash across the North Sea to the coast of England,
