Roman earthworks grip the slopes below Burnswark’s hilltop enclosure. This is one of Scotland’s most striking places to think about the Roman army in action: camps, gateways and scattered missiles combine to tell a story quite different from daily life in a settled auxiliary fort.

Burnswark at a glance
| Feature | Evidence and interpretation |
|---|---|
| Occupation | Roman military activity, probably second century AD; the assault is often associated with the Antonine advance around AD 140. Its exact date remains debated. |
| Garrison | An unidentified Roman field force; no named legion or auxiliary regiment is securely established here. |
| Size | A complex of two Roman camps, a small fortlet and an Iron Age hillfort. The south camp is roughly 6 hectares (about 15 acres); there is no single auxiliary-fort footprint. |
| Probable troop strength | Probably a substantial force numbering in the thousands if the camps were occupied together; a precise headcount is not recoverable. |
A hill between two camps
The northern and southern Roman camps flank an earlier hillfort overlooking the Solway country. On the southern side, the prominent earthworks known as the Three Brethren stand before gateways facing the hill. The relationship between these features is central to interpreting the site: they were arranged around a particular target in the landscape.
Siege, assault or training ground?
For much of the twentieth century, interpretations shifted between a real attack and military training. The Trimontium Trust’s investigations mapped lead sling bullets and other projectiles, strengthening the case for conflict. An assault during the second-century advance is a persuasive interpretation, but the finds do not supply a dated account of the battle or identify its commander.
How many soldiers?
Camp areas cannot be converted into a permanent garrison using the same assumptions as barrack-built forts. Tents, animals, stores and the circumstances of an operation all affected capacity. Several thousand attackers are possible, but neither the combined camp area nor the volume of ammunition proves that a complete legion was present. The smaller fortlet also belongs to the site’s history and should not be treated as the accommodation for the whole attacking army.
Inscriptions and the identity of the troops
No inscription identifying the attacking force has been established in the sources consulted. The most revealing evidence is the distribution of weapons rather than a unit dedication. RIB therefore provides background for the Roman army in the region, not a named Burnswark garrison.
For the regiments and types of troops represented across Scotland, see Auxiliary units in Roman Scotland. The Roman Army guide explains the wider organisation, while Roman fort layout introduces the buildings found in permanent bases.
