Historical references to circadian-based watchbills and fatigue avoidance

If it was good enough for the Romans...

In Rules for Encamping an Army from the “De Re Militari” or The Military Institutions of the Romans by Flavius Vegetius Renatus written in 390 A.D. and translated in 1767 by Lieutenant John Clarke:


“Then the legions and auxiliaries, cavalry and infantry, have the ground distributed to them to pitch their tents according to the rank of the several corps. Four foot-soldiers of each century and four troopers of each troop are on guard every night. As it seemed impossible for a sentinel to remain a whole night on his post, the watches were divided by the hourglass into four parts, that each man might stand only three hours. All guards are mounted by the sound of trumpet and relieved by the sound of cornet. The tribunes choose proper and trusty men to visit the different posts and report to them whatever they find amiss. This is now a military office and the persons appointed to it are called officers of the rounds.”


And consider these quotes from Napoleon Bonaparte:

"You must not needlessly fatigue the troops."

"The first virtue in a soldier is endurance of fatigue; courage is only the second virtue."
