About

Boothby's fortlet, also known as Castle Hill, overlooked the River Irthing from a scarp edge, built in the late first or early second century when the river itself still marked the edge of Roman control in this sector. It belonged to the Stanegate frontier system alongside the confirmed fortlets at Haltwhistle Burn and Throp. A single ditch and clay rampart enclosed just under half a hectare, big enough for a small detachment watching the crossing below. Aerial photography revealed below-ground traces later confirmed by limited excavation under F.G. Simpson in 1933, though a landslip has since carried away part of the northern half of the site. In 117 CE the fortlet still anchored this stretch of the Stanegate line, five years before Hadrian's Wall would be built a few miles north and make the position obsolete.

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.
