 The account of Charlemagne's campaign against the Saxons is also notable as one of the few extant references to the Irminsul, an important if enigmatic part of the Germanic paganism practiced by the Saxons at the time.Its destruction is a major point in the annals, written to continue a jingoistic theme of Frankish triumphs against the “un-Frankish” and unchristian barbarian.The unrevised text neglects to mention defeats suffered by Charlemagne, such as the Battle of Roncevaux Pass in 778 (later dramatized in the "Song of Roland") and the Battle of Süntel in 782.
