In the doubtful lull that followed, a conspiracy was raised against the life and throne of the monarch, in which his natural son, Pepin the Hunchback, was implicated. It was discovered in time, and all the conspirators were put to death, with the exception of Pepin, who was confined for life within a monastery. Scarcely had the king escaped this danger, than he was alarmed by news that the Saxons had revolted, and uniting themselves with the Huns, had given a bloody defeat to his cousin, Theodoric. Close upon this came other tidings of equally evil import. In the late campaign against the Huns, Charlemagne had called to his aid his son Pepin, King of Italy, who, notwithstanding he was himself embroiled with Grimbald, Duke of Beneventum, did not hesitate to obey. To reward this prompt obedience, Charlemagne early in the winter had despatched another son, Louis, King of Aquitaine, to the help of his brother, when the Saracens took advantage of the latter's absence to attack his frontiers, and even penetrated to Narbonne before any forces were ready to oppose them. From this expedition they returned home laden with plunder, and satisfied with this success, remained for a while in quiet. Charles therefore had a brief respite to turn against the Saxons; and as he had hitherto found all his precautions unavailing to keep them within the bounds of good order, he broke up the nation, and transported an immense number of the most turbulent to a distance from their own country. Multitudes of men, women, and children were dispersed over France, and not a few were transported to Brabant and various parts of Flanders. About this time, 793, the first collision took place between the Franks and the piratical Northmen. It would be alien from our present purpose to follow Charlemagne step by step in his march of conquest and civilization. We need only say in general terms, that he drove back the Arabs, reduced the Huns, became the friend of Haroun al Raschid, his only rival in the paths of greatness, and effectually protected his long line of coast from the attempted incursion of the Northmen. It is said that upon one occasion he arrived at a certain port just as the pirates were preparing to land; but the moment they by some means learnt the presence of the monarch, they immediately fled in terror at his mere name. He remained gazing on the departing vessels, while the tears rolled down his cheeks. His nobles could not help showing surprise at such unusual emotion in the monarch, which being observed by him he exclaimed, "I weep not, my friends, because I myself fear these miserable savages; but I weep that they should dare to show themselves upon my coast while I am living, for I foresee the evils they will bring upon my people when I am dead."
