It will be observed by looking upon the map, that the chain of mountains called Mount Taurus extends down near to the coast, at the northeastern corner of the Mediterranean. Among these mountains there are various tracts of open country, through which an army may march to and fro, between Syria and Asia Minor. Now it happened that Darius, in going toward the west, took a more inland route than Alexander, who, on coming eastward, kept nearer to the sea. Alexander did not know that Darius was so near; and as for Darius, he was confident that Alexander was retreating before him; for, as the Macedonian army was so small, and his own forces constituted such an innumerable host, the idea that Alexander would remain to brave a battle was, in his opinion, entirely out of the question. He had, therefore, no doubt that Alexander was retreating. It is, of course, always difficult for two armies, fifty miles apart, to obtain correct ideas of each other's movements. All the ordinary intercommunications of the country are of course stopped, and each general has his scouts out, with orders to intercept all travelers, and to interrupt the communication of intelligence by every means in their power.
