Having opposed the elevation of Charles Martel and the latter's confiscation of church property to fund his war efforts against the Moorish invasions from Al-Andalus, Eucherius found himself out of favor with the new Carolingian dynasty. When Charles Martel returned from his victory at the Battle of Tours, he stopped in Orléans and exiled Eucherius to Cologne. Eucherius retired to the abbey of Sint-Truiden, where he spent the remainder of his life in prayer and contemplation until his death in 743.
