Roman invasion of Caledonia (208–211)

The Roman invasion of Caledonia was launched in 208 by the Roman emperor Septimius Severus. The invasion lasted until late 210, when the emperor became ill and died at Eboracum (York) on 4 February 211. The war started well for the Romans with Severus managing to quickly reach the Antonine Wall, but when Severus pushed north into the highlands he became bogged down in a guerrilla war and he was never able to fully subjugate Caledonia. He reoccupied many forts built by Agricola over 100 years earlier, following the Battle of Mons Graupius, and crippled the ability of the Caledonians to raid Roman Britain.

The invasion was abandoned by Severus' son Caracalla and Roman forces once again withdrew to Hadrian's Wall.
