How Rome Built Soldiers Who Never Got Tired

March twenty Roman miles before lunch with a load as heavy as a child on your back, then pick up a shovel and build a walled camp before dark. Every single day. Rome never found soldiers who couldn't get tired - it manufactured them. This is the story of how a farm boy became a Roman legionary: who Vegetius says Rome picked and turned away, the probatio and the oath, boot camp with wooden swords twice as heavy as the real thing, the training post, river swims and drill twice a day. We march with "Marius' mules" and weigh the real load, watch the army build the same city every night to Polybius' grid and Josephus' three trumpet calls, and look at what fuelled it all: grain, hardtack, posca, hobnailed boots - and the Vindolanda letters asking for socks and beer. Then the discipline that worked without terror (decimation was mostly a legend), Corbulo rebuilding a soft, frozen army in Armenia, Hadrian inspecting ditches at Lambaesis, and the marching camps and roads archaeologists are still finding today.
