For thirty years such was its character. Charlemagne regarded the conquest of Saxony as indispensable for putting a stop to the incursions of the Saxons, and the conversion of the Saxons to Christianity as indispensable for assuring the conquest of Saxony. The Saxons were defending at one and the same time the independence of their country and the gods of their fathers. Here was wherewithal to stir up and foment, on both sides, the profoundest passions; and they burst forth, on both sides, with equal fury. Whithersoever Charlemagne penetrated he built strong castles and churches; and, at his departure, left garrisons and missionaries. When he was gone the Saxons returned, attacked the forts and massacred the garrisons and the missionaries. At the commencement of the struggle, a priest of Anglo-Saxon origin, whom St. Willibrod, bishop of Utrecht, had but lately consecrated, St. Liebwin in fact, undertook to go and preach the Christian religion in the very heart of Saxony, on the banks of the Weser, amidst the general assembly of the Saxons. “What do ye” said he, cross in hand; “the idols ye worship live not, neither do they perceive: they are the work of men’s hands; they can do nought either for themselves or for others. Wherefore the one God, good and just, having compassion on your errors, hath sent me unto you. If ye put not away your iniquity, I foretell unto you a trouble that ye do not expect, and that the King of Heaven hath ordained aforetime; there shall come a prince, strong and wise and indefatigable, not from afar, but from nigh at hand, to fall upon you like a torrent, in order to soften your hard hearts and bow down your proud heads. At one rush he shall invade the country; he shall lay it waste with fire and sword, and carry away your wives and children into captivity.” A thrill of rage ran through the assembly; and already many of those present had begun to cut, in the neighboring woods, stakes sharpened to a point to pierce the priest, when one of the chieftains named Buto cried aloud, “Listen, ye who are the most wise. There have often come unto us ambassadors from neighboring peoples, Northmen, Slavons or Frisons; we have received them in peace, and when their messages have been heard, they have been sent away with a present. Here is an ambassador from a great God, and ye would slay him!” Whether it were from sentiment or from prudence, the multitude was calmed, or at any rate restrained; and for this time the priest retired safe and sound.
