The Pictish and Scottish raids that prompted Emperor Constans's unprecedented midwinter crossing of the Channel in 343 AD. The scale must have been extraordinary — emperors did not cross the Channel in January without overwhelming cause. The Notitia Dignitatum mentions the "areani" (frontier scouts) who operated between the Wall and the northern tribes; they were abolished after the 367 conspiracy when they were found to have been betraying Roman intelligence.
Picts/Scots: c. 2,000–4,000 raiders. Roman garrison: c. 1,000–2,000.
