Upon the heels of this disaster came the news that the Saxons had again arisen under the lead of Wittekind, destroyed their churches, murdered the priests, and carried fire and sword to the very walls of Cologne and Coblentz. Charlemagne sent his best troops, by forced marches, in advance of his coming, but he was not able to take the field until the following spring. During 779 and a part of 780, after much labor and many battles, he seemed to have subdued the stubborn race, the most of whom accepted Christian baptism for the third time. Charlemagne thereupon went to Italy once more, in order to restore order among the Longobards, whose local chiefs were becoming restless in his absence. His two young sons, Pippin and Ludwig, were crowned by Pope Adrian as kings of Longobardia, or Lombardy (which then embraced the greater part of Northern and Central Italy), and Aquitaine. [Sidenote: 783.] After his return to Germany, he convoked a parliament, or popular assembly, at Paderborn, in 782, partly in order to give the Saxons a stronger impression of the power of the Empire. The people seemed quiet, and he was deceived by their bearing; for, after he had left them to return to the Rhine, they rose again, headed by Wittekind, who had been for some years a fugitive in Denmark. Three of Charlemagne's chief officials, who immediately hastened to the scene of trouble with such troops as they could collect, met Wittekind in the Teutoburger Forest, not far from the field where Varus and his legions were destroyed. A similar fate awaited them: the Frank army was so completely cut to pieces that but few escaped to tell the tale.
