Mons Graupius
About
Governor Agricola pushed deep into Caledonia and crushed a coalition of Caledonian tribes led by Calgacus, killing a claimed 10,000 warriors for only 360 Roman dead. It was the northernmost Roman battlefield victory in Britain. Rome still never permanently held the ground it won that day. The site itself remains unidentified among dozens of candidate hills.
What happened here
A Roman army fights the way it camps: in lines, by drill, on ground chosen if possible. The legions form up in cohorts with gaps that let ranks rotate, throw a volley of heavy javelins at close range, and then close with the short sword, pushing behind the shield. Auxiliaries hold the flanks and do most of the cavalry work and most of the skirmishing. Battles are short and decided by whether one line breaks, and the killing happens in the pursuit rather than the fighting. The camp is dug and palisaded every night regardless. Afterwards the dead are stripped and the field is looted for days; the ground is remembered locally long after the campaign is a paragraph in someone's history.
