Now we must hark back and pick up the threads of the story which we dropped at the end of Chapter IX. Look at the map of the French frontier which you will find on the next page. If you trace the present boundary line between France and Germany, you will see it running south from the little state of Luxemburg,[113] in front of Metz, then turning south-east, and proceeding to the Vosges[114] Mountains, along the ridge of which it continues to the border of Switzerland. In July 1870 the French frontier ran eastwards from Luxemburg to the right bank of the Rhine, and continued south along that river to Basel.[115] France, you will observe, then possessed the two frontier provinces of Lorraine and Alsace.[116] The most important town in these provinces is Strassburg, on the left bank of the Rhine. [Illustration] Now look closely at the province of Lorraine, and find Metz. You see that it is marked with a star, which indicates that it is a fortress. It stands on a fertile peninsula, formed by the confluence of the Seille[117] and the Moselle, and is surrounded by low-lying meadows, which are now rich market gardens. There is hill country to the west and hill country to the east and south, so that it is naturally a strong place and capable of resisting attacks. At the time of which we are speaking it was the strongest fortress of France. Let us suppose that we have the invisible cloak of the fairies, and are thus enabled to enter unseen the long dining-room of the Hôtel de l'Europe in Metz during the closing days of July 1870. The first figure to catch our eye is that of the Emperor Napoleon III. We observe that he is a grave, dreamy man, with nothing of the first Napoleon's power and determination. We guess that he is seriously ill, and our guess is true; for he is suffering from an incurable complaint, which will soon render him incapable of directing the affairs of the army and the country. Ever since he was a child the great Napoleon has been his ideal, and he has long dreamed of founding an empire just as great as his uncle's, but far more lasting. By his side you see a boy of fourteen, the Prince Imperial,[118] his only son. Before another month is over this boy will receive his baptism of fire, and will bear himself on the battlefield with a coolness far beyond his years. He will, however, never wear the crown of France, and nine years later will receive his death-wound while fighting for Britain in South Africa.
