History has seen many who claim to be deliverer and saviour of the people. They might come with force and violence and parade their might and splendour as conquerors. The pharaohs of Egypt, Sennacherib king of Assyria, Nebuchadnezzar of Babylon, Darius of Persia, Alexander the Great, Hannibal, Napoleon, Clive of India, Bismarck, the Kaiser, Hitler, Stalin. The story and scene is always the same. They claim to deliver the people from bondage and to establish justice, freedom and peace. They come in might, riding in splendour, dragging prisoners.

Our enemies are Medes and Persians, men who for centuries have lived soft and luxurious lives; we of Macedon for generations past have been trained in the hard school of danger and war. Above all, we are free men, and they are slaves. There are Greek troops, to be sure, in Persian service — but how different is their cause from ours! They will be fighting for pay — and not much of at that; we, on the contrary, shall fight for Greece, and our hearts will be in it. As for our foreign troops — Thracians, Paeonians, Illyrians, Agrianes — they are the best and stoutest soldiers in Europe, and they will find as their opponents the slackest and softest of the tribes of Asia. And what, finally, of the two men in supreme command? You have Alexander, they — Darius!
