the passes of the Alps, offered a vigorous resistance; but when the second army had penetrated into Italy by Mount St. Bernard, Didier, threatened in his rear, retired precipitately, and, driven from position to position, was obliged to go and shut himself up in Pavia, the strongest place in his kingdom, whither Charlemagne, having received on the march the submission of the principal counts and nearly all the towns of Lombardy, came promptly to besiege him.

To place textually before the reader a fragment of an old chronicle will serve better than any modern description to show the impression of admiration and fear produced upon his contemporaries by Charlemagne, his person and his power.  At the close of this ninth century a monk of the abbey of St. Gall, in Switzerland, had collected, direct from the mouth of one of Charlemagne’s warriors, Adalbert, numerous stories of his campaigns and his life.  These stories are full of fabulous legends, puerile anecdotes, distorted reminiscences and chronological errors, and they are written sometimes with a credulity and exaggeration of language which raise a smile; but they reveal the state of men’s minds and fancies within the circle of Charlemagne’s influence and at the sight of him.  This monk gives a naive account of Charlemagne’s arrival before Pavia, and of the King of the Lombard’s disquietude at his approach.  Didier had with him at that time one of Charlemagne’s most famous comrades, Ogier the Dane, who fills a prominent place in the romances and epopaeias, relating to chivalry, of that age.  Ogier had quarrelled with his great chief and taken refuge with the King of the Lombards.  It is probable that his Danish origin and his relations with the King of the Danes, Gottfried, for a long time an enemy of the Franks, had something to do with his misunderstanding with Charlemagne.  However that may have been, “when Didier and Ogger (for so the monk calls him) heard that the dread monarch was coming, they ascended a tower of vast height whence they could watch his arrival from afar off and from every quarter.  They saw, first of all, engines of war such as must have been necessary for the armies of Darius or Julius Caesar.  ‘Is not Charles,’ asked Didier of Ogger, ‘with his great army?’ But the other answered, ‘No.’  The Lombard, seeing afterward an immense body of soldiery gathered from all quarters of the vast empire, said to Ogger, ’Certes, Charles advanceth in triumph in the midst of this throng.’  ’No, not yet; he will not appear so soon,’ was the answer.  ‘What should we do, then,’ rejoined Didier, who began to be perturbed, ’should he come accompanied by a larger band of warriors?’ ‘You will see what he is when he comes,’ replied Ogger, ‘but as to what will become of us, I know nothing.’  As they were thus parleying appeared the body of guards that knew no repose; and at this sight the Lombard, overcome with dread, cried, ’This time ‘tis surely Charles.’  ‘No,’ answered Ogger, ‘not yet.’
