Mud and misery at the empire’s edge.
In late October, Roman legions from Britannia to the Rhine brace for the world to turn. The nights sharpen, rain turns roads to soup, and supply wagons groan in the muck. For most armies, the ancient fighting season slams shut—soldiers sharpen shovels instead of swords.
Winter closes Rome’s campaigns.
The armies dig in, build new turf walls, and fill every ditch with brush and hope. Losing men to weather, not war, was the old enemy. Generals and rankers alike count the days until the first spring messenger arrives with orders to march.
As October closes, muddy roads and chill winds force Rome’s armies to hunker down for winter. War waits for spring.
