Adalhelm wrote a life and miracles of Saint Opportuna of Montreuil, Vita et miracula Sanctae Opportunae.^[2] It includes an autobiographical account of how he was captured by Vikings in the year of his consecration and sold into slavery. It is the only first-hand account of a Viking slave. He escaped or was redeemed and returned to Séez, where he fulfilled a vow had made by writing the life of Opportuna. The Vita survives only in a 14th-century manuscript and an early modern edition.^[3]
