Such being the case, the Germans, though they had long toasted "The Day" on which they were going to destroy our naval supremacy for ever, dared not leave their harbours and show fight. They were very wise in this respect. They knew that pitched battles could only end in one way--the entire destruction of their navy. You read in Chapter XVII. of Volume I. that their plan was to strew the North Sea with mines, in the hope that our ships would bump upon them and be blown up. In this way they hoped that our strength would be slowly reduced to their own level. The Germans meant to keep their fleet in safety until they could fight us upon even terms. They believed that our sailors ploughing the sea day after day in search of an enemy that could not be found, and going in constant terror of floating mines and submarines, would grow stale and dispirited. Then when many of our ships had gone down, and our men were worn out in body and in mind, they meant to sally forth and crush British sea-power once and for all. It was an excellent plan--on paper. Before I pass on to describe the first sea fight of the war, let us look for a moment at the coast line of Germany. It is, as you know, entirely confined to a strip on the North Sea, and to a long stretch on the Baltic Sea. On both these sea fronts Germany had to meet a naval power--the British in the North Sea, and the Russians in the Baltic. You were told on page 141 of Volume I. that, in order to enable German warships to pass rapidly from one front to the other, the Kiel Canal has been constructed. The work of widening and deepening this canal was completed some six weeks before the outbreak of war. The German coast on the North Sea is only about a hundred miles from west to east, not counting indentations; and it is washed by very shallow waters, which are much impeded by sandbanks. The sea is gaining on the shore, as you may notice from the long line of fringing islands which were formerly part of the mainland. Close to the Dutch frontier, on the estuary of the Ems, is the port and manufacturing town of Emden. The Germans have spent much money in constructing at Emden a harbour big enough and deep enough to accommodate the largest liners and warships. Between the mouth of the Ems and the Jade there is a long, sandy stretch of coast, backed by dunes and broken by tidal creeks. On the west side of the Jade estuary stands Wilhelmshaven, the great North Sea naval base of Germany. It was established by the present Kaiser's grandfather in 1869, and is very strongly fortified. It boasts two harbours, several wet and dry docks, coaling basins, and a large naval barracks. In time of peace the First Squadron of the German High Sea Fleet is stationed at Wilhelmshaven.
