Bede. 676. In the year of our Lord's incarnation 676, when Ethelred, king of the Mercians, ravaged Kent with a powerful army, and profaned churches and monasteries, without regard to religion, or the fear of God, he among the rest destroyed the city of Rochester [Map]; Putta, who was bishop, was absent at that time, but when he understood that his church was ravaged, and all things taken away, he went to Sexwulf, bishop of the Mercians, and having received of him a certain church, and a small spot of land, ended his days there in peace; in no way endeavouring to restore his bishopric, because (as has been said above) he was more industrious in spiritual than in worldly affairs; serving God only in that church, and going wherever he was desired, to teach church music. Theodore (age 74) consecrated Cuichelm bishop of Rochester in his stead; but he, not long after, departing from his bishopric for want of necessaries, and withdrawing to other parts, Gebmund was substituted in his place.
In 676 Bishop Cwichhelm was consecrated Bishop of Rochester.
In 678 Bishop Cwichhelm resigned the see of Rochester.
