On September 3, 1650, exactly 426 years before this article was published, the Battle of Dunbar changed the course of Scotland’s seventeenth-century history. Fought near Dunbar in East Lothian, the battle ended with Oliver Cromwell’s English Parliamentarian army defeating the Scottish force commanded by David Leslie during the Wars of the Three Kingdoms. The victory shifted the balance of the campaign in Scotland and set in motion a grim aftermath for thousands of captured Scottish soldiers. This guide explains why the Battle of Dunbar happened, how the landscape shaped the fighting, what became of the prisoners, and what visitors can still connect to the event today.
Battle of Dunbar in Brief
The Scottish army entered the campaign from a position that appeared stronger than Cromwell’s. After Charles I was executed in 1649, Scotland recognized his son, Charles II. Cromwell invaded Scotland in the summer of 1650 as the political confrontation between the English Commonwealth and the Scottish government moved toward war.
David Leslie avoided giving Cromwell the open battle he wanted. Instead, the Scots used defensive positions and pressure on English supplies. By early September, Cromwell’s weakened army had withdrawn toward Dunbar and appeared to be in serious danger.
Yet within hours, the situation reversed. The Scottish army moved from its strong position on Doon Hill, Cromwell found an opening, and the Battle of Dunbar became one of the defining victories of his military career.
Why Doon Hill and the Brox Burn Mattered at the Battle of Dunbar
You understand Dunbar much more clearly when you look at the ground.
Leslie’s army held Doon Hill south of the town. Below lay the Brox Burn, a stream running through a steep-sided channel. Cromwell’s army occupied the lower ground closer to Dunbar and the coast.
The Scottish position restricted Cromwell’s route toward England. However, moving troops down from the hill compressed parts of Leslie’s army into more difficult terrain near the burn.
Historic Environment Scotland identifies the lower slopes of Doon Hill and the Brox Burn as central features of the battlefield. Modern roads, the railway, quarrying, and development have altered portions of the landscape, but important relationships between the hill, burn, Broxmouth, and Dunbar can still be understood.
What Happened on September 3, 1650?
The English attack began around dawn. Cromwell concentrated his strongest forces against the Scottish right, where the deployment on the lower ground offered an opportunity that had not existed while Leslie’s army remained securely positioned above.
The first fighting was hard. Scottish troops resisted the Parliamentarian assault, but English forces increased the pressure and exploited the restricted Scottish deployment. Once the Scottish right began to collapse, Leslie’s army struggled to recover its formation. The retreat became a rout.
The size of the armies and the number of casualties remain disputed. Older estimates placed the Scottish army at roughly 22,000, while later assessments have suggested a considerably smaller force. Cromwell reported about 3,000 Scots killed, but Scottish accounts gave lower totals. Those differences are a reminder that exact numbers from seventeenth-century battles should be treated cautiously.

What Happened to the Scottish Prisoners After the Battle of Dunbar?
The aftermath is the part of the Battle of Dunbar story that connects most strongly to individual lives.
Cromwell reported taking roughly 9,000 to 10,000 prisoners. Older, wounded, and sick men were released, while about 4,000 prisoners were reportedly sent south into England. Disease, exhaustion, hunger, escape, and death reduced their numbers during the journey.
Around 3,000 common soldiers ultimately reached Durham, where they were confined in Durham Cathedral. Dysentery spread among them. Research on the prisoners reports that more than 1,600 had died by October 31, 1650.
Modern archaeology has added remarkable detail to this story. Human remains uncovered at Palace Green in Durham were studied through archaeology, osteology, and scientific analysis. Researchers concluded that the evidence was consistent with the remains belonging to Scottish soldiers captured after Dunbar.
Following the Prisoners South to Durham
The prisoners’ journey makes the scale of the aftermath easier to grasp. Thousands left the battlefield, but substantially fewer reached Durham. For family historians, that difference represents individual stories of death, escape, survival, forced labor, and later migration.
Why the Battle of Dunbar Still Matters
Dunbar changed the campaign quickly. The defeat weakened organized Scottish resistance in southern Scotland and left the region open to Cromwell’s advance. Historic Environment Scotland describes Dunbar as the most influential battle fought in Scotland during the Wars of the Three Kingdoms.
Its importance is not limited to Cromwell’s military reputation. The battlefield preserves a physical connection to the event, while the Durham research restores attention to ordinary men who otherwise survive only faintly in the historical record.
That combination makes Dunbar particularly valuable for heritage travelers and family historians. You can study the strategy on the landscape and then follow the consequences through surviving documents and archaeological evidence.

Visiting the Battle of Dunbar Landscape
The battlefield is not a preserved military park with every movement marked for visitors. Its value lies instead in the surviving landscape.
Doon Hill, the Brox Burn, Broxmouth, and the approaches to Dunbar still allow you to understand the geography that shaped the battle. Later transportation routes, quarrying, and development have changed parts of the scene, which makes a battlefield map especially useful when comparing the modern ground with the events of 1650.
If you visit, approach Dunbar as a historic landscape rather than a single attraction. Looking from Doon Hill toward Dunbar helps explain Leslie’s original advantage, while the surviving battlefield area allows you to see why movement across the lower ground mattered so much.
Frequently Asked Questions
When was the Battle of Dunbar?
The Battle of Dunbar was fought on September 3, 1650.
Who commanded the two armies?
Oliver Cromwell commanded the English Parliamentarian army. David Leslie commanded the Scottish army.
Why did the Scots lose?
No single explanation is sufficient. The Scottish army surrendered part of the advantage provided by its position on Doon Hill, while Cromwell concentrated his attack against a vulnerable section of the Scottish line. Terrain, deployment, timing, and Parliamentarian discipline all contributed.
What happened to the Scottish prisoners?
Thousands were captured. About 4,000 were reportedly sent south, around 3,000 reached Durham, and more than 1,600 had died by the end of October 1650. Historical totals vary, so these figures should be treated as approximate rather than exact counts.
Can you visit the battlefield today?
Yes. The wider battlefield landscape survives around Dunbar, Doon Hill, Broxmouth, and the Brox Burn, although modern development and quarrying have altered portions of it.
