Note 620 — Chapter V · THE DANISH CONQUEST OF ENGLAND.[464] 975–1016. (continued 2)
Reading edition
So I understand the narrative in the Chronicles, which seems to imply that the measures of Ulfcytel were taken as soon as the Danes began their march, but before they reached Thetford, while Florence does not mention Ulfcytel as doing anything till after he hears of the burning of the town.
