It was now mid-day. The victors, elated with their success and their hopes of pillage, followed the retreating columns along the banks of the river Corace, feeling so secure that they laid aside their arms and marched leisurely and confidently forward. It was a fatal confidence. At one point in their march the road led between the river and a ridge of serried rocks, which lay silent beneath the mid-day sun. But silent as they seemed, they were instinct with life. An ambuscade of Arabs crouched behind them, impatiently waiting the coming of the unsuspecting Germans. Suddenly the air pealed with sound, the "Allah il Allah!" of the fanatical Arabs; suddenly the startled eyes of the imperialists saw the rugged rocks bursting, as it seemed, into life; suddenly a horde of dusky warriors poured down upon them with scimitar and javelin, surrounding them quickly on all sides, cutting and slashing their way deeply into the disordered ranks. The scattered troops, stricken with dismay, fell in hundreds. In their surprise and confusion they became easy victims to their agile foes, and in a short time nearly the whole of that recently victorious army were slain or taken prisoners. Of the entire force only a small number broke through the lines of their environing foes. The emperor escaped almost by miracle. His trusty steed bore him unharmed through the crowding Arabs. He was sharply pursued, but the swift animal distanced the pursuers, and before long he reached the sea-shore, over whose firm sands he guided his horse, though with little hope of escaping his active foes. Fortunately, he soon perceived a Greek vessel at no great distance from the shore, a vision which held out to him a forlorn hope of escape. The land was perilous; the sea might be more propitious; he forced his faithful animal into the water, and swam towards the vessel, in the double hope of being rescued and remaining unknown. He was successful in both particulars. The crew willingly took him on board, ignorant of his high rank, but deeming him to be a knight of distinction, from whom they could fairly hope for a handsome ransom. His situation was still a dangerous one, should he become known, and he could not long hope to remain incognito. In truth, there was a slave on board who knew him, but who, for purposes of his own, kept the perilous secret. He communicated by stealth with the emperor, told him of his recognition, and arranged with him a plan of escape. In pursuance of this he told the Greeks that their captive was a chamberlain of the emperor, a statement which Otho confirmed, and added that he had valuable treasures at Rossano, which, if they would sail thither, they might take on board as his ransom.
