Peter Woodward raises a Roman legion and trains them on the weapons that won an empire. To prepare for battle, soldiers march for hours, drill with heavy wooden swords, learn to use a dagger (pugio), throw a javelin (pilum) with pinpoint accuracy, and are introduced to the Gladius Hispaniensis--the short sword that shaped the ancient world. Woodward reveals how the Romans used superior training and weaponry to become the greatest ancient military force and model for every professional army since.
