Ancient history

Movements

The discipline and training of the legions is also evident in his movements, and especially in his paces of march. The normal pace is 5 kilometers in one hour, then a 10-minute break. This pace is maintained for 5 to 7 hours of walking per day. There is also an accelerated rate of 7.2 kilometers in 50 minutes, sometimes maintained for more hours (8 or 9 exceptionally), in case of emergency (to help another legion).

This speed of movement (unmatched until the French Revolution) gives great operational advantages to the Roman legion:it allows to gather twice as many troops as the enemy in a given place, before he can react.

Baggage reduces this speed by a third (normal stage of 25 kilometres). Every evening a fortified camp is built.

Under the Empire, this pace was possible thanks to training (ambulatura) taking place at least three times a month, on a fixed date (regardless of the weather). All the soldiers take care of all the regulatory equipment (up to 40 kilograms) and travel, via rough routes, about forty kilometers, alternating between the two paces.
