About

Rome planted a cavalry garrison at the confluence of the Günz and Danube rivers around AD 77 to lock down a key river crossing on the Raetian frontier. Riders stationed here spent decades patrolling the water approach into the province rather than facing pitched battles. The base gave its name to the modern town that grew from its vicus, and the crossing itself stayed strategically important long after Trajan's reign, still guarded as the transitus guntiensis into the late Roman period. Günzburg's town center sits directly over ground its Roman garrison once patrolled.

What happened here

Five hundred men, sometimes a thousand, recruited from a province rather than from citizens, and often stationed a long way from where they were raised. Cavalry units get a bigger fort and far more stabling; the smell tells you which kind you are in before the plan does. The layout copies a legionary fortress at a quarter of the size — headquarters, commander's house, granaries, barracks, a bath house usually built outside the walls because of the fire risk. Duties are patrolling, escorting, customs, and policing rather than pitched battle. After twenty-five years a man is discharged with citizenship for himself and his children, recorded on a bronze diploma he keeps for life. A village grows outside the gate within a decade.
