But during all the years of the Saxon wars, Charlemagne had been carrying on various campaigns elsewhere. The Lombards were again at war with the Popes, and the king of Lombards, Didier, whose daughter Charlemagne had married and so soon divorced, had now become his bitter foe. The new Pope, Adrian I., sought the aid of Charlemagne in this war with the Lombards, and he prepared for this Italian expedition. He raised two armies,—one to cross the Valais and descend upon Lombardy by Mount St. Bernard, and the other, to be led by Charlemagne, was to go by the way of Mount Cenis. Didier had with him a famous Dane, named Ogier, who had quarrelled with Charlemagne and taken refuge in Lombardy. One of the monks of that time thus describes Charlemagne’s arrival before Pavia, where Didier and the Dane Ogier had shut themselves up, as it was the strongest place in Lombardy. “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 wars, such as must have been necessary for the armies of Darius or Julius Cæsar. ‘Is not Charles,’ asked Didier of Ogger, ‘with this great army?’ But the other answered, ‘No.’ The Lombard, seeing afterwards 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.’ In their wake came the bishops, the abbots, the ordinaries of the chapels royal, and the counts; and then Didier, no longer able to bear the light of day or to face death, cried out with groans, ‘Let us descend and hide ourselves in the bowels of the earth, far from the face and the fury of so terrible a foe.’ Trembling the while, Ogger, who knew by experience what were the power and might of Charles, and who had learned the lesson by long usage in better days, then said, ‘When ye shall behold the crops shaking for fear in the fields, and the gloomy Po and the Ticino overflowing the walls of the city with their waves blackened with steel (iron), then may ye think that Charles is coming.’ He had not ended these words when there began to be seen in the west, as it were, a black cloud, raised by the north-west wind or by Boreas, which turned the brightest day into awful shadows. But as the emperor drew nearer and nearer, the gleam of arms caused to shine on the people
