In 52 BCE, Julius Caesar faced a dangerous situation at Alesia: the Gallic defenders were inside the stronghold, while another army could arrive to rescue them.

His Roman forces constructed two defensive lines. The inner works contained the besieged defenders, while the outer works protected the Roman army from the approaching relief force.

Trenches, earth ramparts, timber palisades and defensive towers helped transform the landscape into a vast military engineering system.

This cinematic historical reconstruction explores how Roman engineering helped Caesar manage threats from opposite directions.
