And presently Narses himself could enjoy from the hill the magnificent spectacle of the approach of the fleet, propelled not only by their spreading sails, but also by their long oars. Much relieved, he again turned his attention to the combat upon Vesuvius--when, suddenly, messengers reached him from the camp, affirming the first reports in an alarming manner, or rather, they brought much worse news. They had hurried on in advance of an embassy which reached the litter of Narses just as Cethegus was advancing for the last time against Teja. This embassy consisted of the admiral and captains of the Ionian fleet, who came forward with their hands in chains, and guarded by four Northmen, whose message they had been brought to interpret. They briefly related that they had been attacked by the fleet of the Viking one stormy night, and had lost almost all their ships; that not one could escape to warn Narses, for the enemy had blockaded the harbour. When Jarl Harald had heard of the threatened destruction of the Goths upon Vesuvius, he had sworn to prevent or to share their evil fate. And sending the captured Grecian ships in advance, prudently hiding behind them his dragon-ships, he had hurried to the coast of Neapolis on the wings of the east wind. "And thus," concluded the interpreters, "thus says Harald the Viking: 'Either you will allow all yet living Goths, with all their weapons and goods, to leave the Southland upon our ships and return with us to their fatherland; in return for which we will give up all our thousands of prisoners, and all our prize-ships, except those we need for the transport of the Goths; or we will immediately kill our prisoners, land, and attack you, your camp and army, in the rear. Then see to it, how many of you, when attacked in front by the Goths, in the rear by us, will remain alive! For we Northmen fight to the last man! I have sworn it by Odin.'" Without a moment's hesitation Narses agreed to the departure of the Goths. "I have only sworn to drive them out of the Empire," he said, "not out of the world. It would bring me small renown if I overpowered and slaughtered the poor remains of such a noble nation. I reverence the heroism of this Teja; in forty years of warfare I have never seen his like. And I have no desire to try how my harassed army, which has had a day of the hardest fighting, and has lost almost all its leaders and numbers of its bravest soldiers, would resist these northern giants, who come with untired strength and unconquered courage." And so Narses had immediately sent heralds to Harald and to the pass. The battle ceased; the retreat of the Goths began. In double ranks, reaching from the summit of the mountain down to the sea, the army of heroes formed a lane. The Viking had landed four hundred men, who received the Goths on the sea-shore. But before the march began, Karses signed to Basiliskos and said:
