At this assembly suddenly appeared a deputation of Saracen princes from Spain, who sought Charlemagne's help against the tyranny of the Caliph of Cordova. He was induced by religious or ambitious motives to consent, neglecting for the time the great work he had undertaken in his own Empire. In the summer of 778 he crossed the Pyrenees, took the cities of Pampeluna and Saragossa, and delivered all Spain north of the Ebro river from the hands of the Saracen Caliph. This territory was attached to the Empire as the Spanish Mark, or province: it was inhabited both by Saracens and Franks, who dwelt side by side and became more or less united in language, habits and manners.
On his return to France, Charlemagne was attacked by a large force of the native Basques, in the pass of Roncesvalles, in the Pyrenees. His warriors, taken by surprise in the narrow ravine and crushed by rocks rolled down upon them from above, could make little resistance, and the rear column, with all the plunder gathered in Spain, fell into the enemy's hands. Here was slain the famous paladin, Roland, the Count of Brittany, who became the theme of poets down to the time of Ariosto. Charlemagne was so infuriated by his defeat that he hanged the Duke of Aquitaine, on the charge of treachery, because his territory included a part of the lands of the Basques.
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.
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.
Charlemagne marched immediately into the Saxon land: the rebels dispersed at his approach and Wittekind again became a fugitive. The Saxon nobles humbly renewed their submission, and tried to throw the whole responsibility of the rebellion upon Wittekind. Charlemagne was not satisfied: he had been mortified in his pride as a monarch, and for once he cast aside his usual moderation and prudence. He demanded that 4,500 Saxons, no doubt the most prominent among the people, should be given up to him, and then ordered them all to be beheaded on the same day. This deed of blood, instead of intimidating the Saxons, provoked them to fury. They arose as one man, and in 783 defeated Charlemagne near Detmold. He retreated to Paderborn, received reinforcements, and was enabled to venture a second battle, in which he was victorious. He remained for two years longer in Thuringia and Saxony, during which time he undertook a winter campaign, for which the people were not prepared. By the summer of 785, the Saxons, finding their homes destroyed and themselves rapidly diminishing in numbers, yielded to the mercy of the conqueror. Wittekind, who, the legend says, had stolen in disguise into Charlemagne's camp, was so impressed by the bearing of the king and the pomp of the religious services, that he also submitted and received baptism. One account states that Charlemagne named him Duke of the Saxons and was thenceforth his friend; another, that he sank into obscurity.
788. SUBJECTION OF BAVARIA.
Charlemagne was now free to make another journey to Italy, where he suppressed some fresh troubles among the Lombards (as we must henceforth style the Longobards), and forced Aragis, the Duke of Benevento, to render his submission. Then, for the first time, he turned his attention to the Bavarians, whose Duke, Tassilo, had preserved an armed neutrality during the previous wars, but was suspected of secretly conspiring with the Lombards, Byzantines, and even the Avars, for help to enable him to throw off the Frank yoke. At a general diet of the whole empire, held in Worms in 787, Tassilo did not appear, and Charlemagne made this a pretext for invading Bavaria.
Three armies, in Italy, Suabia and Thuringia, were set in motion at the same time, and resistance appeared so hopeless that Tassilo surrendered at once. Charlemagne pardoned him at first, under stipulations of stricter dependence, but he was convicted of conspiracy at a diet held the following year, when he and his sons were found guilty and sent into a monastery. His dynasty came to an end, and Bavaria was portioned out among a number of Frank Counts, the people, nevertheless, being allowed to retain their own political institutions.
The incorporation of Bavaria with the Frank empire brought a new task to Charlemagne. The Avars, who had gradually extended their rule across the Alps, nearly to the Adriatic, were strong and dangerous neighbors. In 791 he entered their territory and laid it waste, as far as the river Raab; then, having lost all his horses on the march, he was obliged to return. At home, a new trouble awaited him. His son, Pippin, whom he had installed as king of Lombardy, was discovered to be at the head of a conspiracy to usurp his own throne. Pippin was terribly flogged, and then sent into a monastery for the rest of his days; his fellow-conspirators were executed.
