I want to know the answer to the following question:
What was the final year that the Umayyads held Narbonne?
All the background I'm provided with is that "From the caliphate's north-western African bases, a series of raids on coastal areas of the Visigothic Kingdom paved the way to the permanent occupation of most of Iberia by the Umayyads (starting in 711), and on into south-eastern Gaul (last stronghold at Narbonne in 759).". Is that enough to answer the question?
Answer: yes
