The Battle of Mons Graupius takes place in what is today northeast Scotland 83 or 84 AD.

Gnaeus Julius Agricola, the Roman governor has sent his fleet ahead to panic the Caledonians, and, with light infantry reinforced with British auxiliaries, reaches the site, which he finds occupied by the enemy.Even though the Romans are outnumbered in their campaign against the tribes of Britain, they often have difficulties in getting their foes to face them in open battle.

The Caledonians are the last to be subdued.

After many years of avoiding the fight, the Caledonians are forced to join battle when the Romans march on the main granaries of the Caledonians, just as they had been filled from the harvest.

The Caledonians have no choice but to fight, or starve over the next winter.
