The Death of Septimius Severus

The final campaign in Caledonia had been a disaster. The Romans lost something on the order of 50,000 men and the Caledonians while somewhat chastened had by no means been brought to heel. At this point the Romans stopped trying to conquer Scotland which was probably a prudent move. But really Severus could have just ordered that done without having to waste all the blood and treasure his war in the highlands had just cost the empire.
