The Battle

History & Significance

The greatest disaster in late Roman Britain. Three separate peoples — the Picts, the Scots (Irish Gaels), and the Attacotti (possibly from the western isles) — mounted a coordinated simultaneous attack that overwhelmed the Roman defences. The Saxons attacked by sea. The Count of the Saxon Shore (Nectaridus) was killed; the Duke of Britain (Fullofaudes) was ambushed and captured. Hadrian's Wall garrison melted away — the "arcani" (frontier intelligence agents) had apparently betrayed Roman dispositions to the enemy. The province descended into chaos.

Both senior commanders lost; widespread destruction

Forces Involved
