The fugitives reached Lombardy, where Tafo was hospitably received by the king, and succeeded his father as Grand Duke of Friuli.  Grimoald was adopted by Arigil, Duke of Benevento, in whose court he grew to manhood, and in whose service his courage and military ability were quickly shown.  There were wars between Benevento and the Greeks of southern Italy, and in these the young soldier so greatly distinguished himself that on the death of Arigil he succeeded him as Duke of Benevento.

Meanwhile, troubles arose in Lombardy.  Tafo had been falsely accused, by an enemy of the queen, of criminal relations with her, and was put to death by the king.  Her innocence was afterwards proved, and on the death of Ariowald the Lombards treated her with the greatest respect, and raised Rotharis, her second husband, to the throne.  He, too, died, and Aribert, uncle of the queen, was next made king.  On his death, his two sons, Bertarit and Godebert, disputed the succession.  A struggle ensued between the rival brothers, in the course of which Grimoald was brought into the dispute.

The events here briefly described had taken place while Grimoald was engaged in the Greek wars of his patron, Duke Arigil.  When he succeeded the latter in the ducal chair, the struggle between Bertarit and Godebert was going on, and the new Duke of Benevento declared in favor of the latter, who was his personal friend.

A scheme of treachery, of a singular character, put an end to their friendship and to the life of Godebert.  A man who was skilled in the arts of dissimulation, and who was secretly in the pay of Bertarit, persuaded Godebert that his seeming friend, Duke Grimoald, was really his enemy, and was plotting his destruction.  He told the same story to Grimoald, making him believe that Godebert was his secret foe.  In proof of his words he told each of them that the other wore armor beneath his clothes, through fear of assassination by his assumed friend.

The suspicion thus artfully aroused produced the very state of things which the agent of mischief had declared to exist.  Each of the friends put on armor, as a protection against treachery from the other, and when they sought to test the truth of the spy’s story it seemed fully confirmed.  Each discovered that the other wore secret armor, without learning that it had just been assumed.

The two close friends were thus converted by a plotting Iago into distrustful enemies, each fearing and on guard against assassination by the other.  The affair ended tragically.  Grimoald was no sooner fully convinced of the truth of what had been told him than he slew his supposed enemy, deeming it necessary to save his own life.  The dark scheme had succeeded.  Treason and falsehood had sown death between two friends.

Bertarit, his rival removed, deemed the throne now securely his.  But the truth underlying the tragedy we have described became known, and the Lombards, convinced of the innocence of Grimoald, and scorning the treachery by which he had been led on to murder, dismissed Bertarit’s pretensions and placed Grimoald on the throne.  His career had been a strange but highly successful one.  From his childhood captivity to the Avars he had risen to the high station of King of Lombardy, a position fairly earned by his courage and ability.
