The bleak Pennine crossing between the Eden valley and Teesdale, a Roman road, a frontier marked by the Rey Cross, and the place where Eric Bloodaxe is said to have been killed in 954.
Stainmore is a stretch of high, bare moorland in the northern Pennines, on the boundaries of Cumbria, County Durham and North Yorkshire. Its name is recorded from about 990 as Stanmoir, the stony moor, which is an exact description of the ground.
It is a region rather than a site. What gives it importance is that it is the lowest and broadest saddle across the northern Pennines — the Stainmore Gap, the summit of the old railway line over it standing at about 420 metres — and therefore the natural route between the Eden valley in the west and Teesdale in the east. Armies, traders and, if the tradition is right, a fleeing Norse king all used it.
The Pennines run the length of northern England and are crossed easily in very few places. Stainmore is one of them, which is why the route has been in continuous use from the Roman period to the present trunk road, and why control of it mattered to anyone holding either York or the north-west.
The country itself is unforgiving — peat, rough grass, and weather that closes the road in winter. Nothing grows here worth fighting for; the value is entirely in the passage. That is the single fact that explains every event associated with the name.
The Romans took the obvious line, running a road across the pass between the forts at Bowes and Brough, with a marching camp at Rey Cross — now a Scheduled Monument — and a signal station on the heights. The camp is one of the more substantial Roman earthworks in the region and it fixes the antiquity of the route.
The Rey Cross itself is a tenth-century cross standing near the summit, and it has carried a heavy load of interpretation. It has long been read as the boundary marker between English Northumbria and the British kingdom of Strathclyde or Cumbria, and it has also been explained as a tomb marker or a memorial. Scholars genuinely disagree, and there is no further evidence to settle it — an early medieval cross on a watershed, doing whatever it was put there to do.
In 954 the Northumbrians expelled their king Eric, the last Norse ruler of York. The fullest account of what happened next comes from Roger of Wendover, writing in the thirteenth century, three hundred years after the event: Eric was "treacherously killed by Earl Maccus in a certain lonely place which is called Stainmore", betrayed by Earl Oswulf, and died there together with his son Haeric and his brother Ragnald.
The contemporary evidence says far less. The Anglo-Saxon Chronicle’s D-text records only that the Northumbrians drove him out in 954 — no ambush, no Stainmore, no Maccus and no Oswulf. Roger was probably drawing on a northern source now lost, and most historians accept the general outline while treating the detail with caution. The one thing that fits is the aftermath: Oswulf, high-reeve of Bamburgh, was made earl of the whole of Northumbria the following year, which is what a man who had arranged a betrayal might expect.
A larger question sits behind it. Whether Eric of York was the same man as Eric Bloodaxe, son of Harald Fairhair and briefly king in Norway, has been seriously disputed — Clare Downham has argued that later Norse writers combined two different Erics into one figure — and no consensus has emerged. The archive records the traditional identification while noting that it is contested.
Eric’s death, whatever its details, marks the end of an independent Northumbria. No king ruled at York again: the kingdom was absorbed into a single English realm, and the alternation of English and Norse rulers that had gone on since the 870s stopped for good.
Stainmore itself carried on as what it had always been — a road over the moor. The Rey Cross stands near the modern route, the Roman camp survives beside it, and there is no monument to the king who is supposed to have died somewhere on these miles of open ground.
