The Romans left Caledonia and moved further south in Britannia to deal with attacks from the Scots tribe from Ireland and the Anglo-Saxons from northern Europe. Soldiers were also needed to deal with conflicts in other parts of the Roman Empire. The Romans faced ongoing difficulties from increasingly organised Caledonian tribes. The Romans left behind a wealthier land with increased cooperation between the tribes living there.
The students could role-play the story of the Roman invasion of Caledonia and also the retreat, with various groups playing the part of Northern tribes and others the Romans.
