Battle of Bannockburn

Setting the scene

The Battle of Bannockburn was the decisive battle of the First War of Scottish Independence. After William Wallace's defeat at Falkirk (1298), Robert the Bruce had murdered his rival John Comyn in 1306 and crowned himself King of Scots. Edward I of England died in 1307, succeeded by his inept son Edward II. By 1314, Bruce controlled most of Scotland, but Stirling Castle, the key to central Scotland, remained in English hands under siege by the Scots. Edward II assembled a large army—perhaps 15,000-20,000 men, including 2,000-3,000 cavalry—to relieve it.

What happened

The armies met near Stirling on June 23-24, 1314, at Bannockburn, a stream south of the castle. Bruce, with 5,000-7,000 men, mostly infantry spearmen, chose ground carefully—marshy terrain that would disrupt English cavalry. On the 23rd, English vanguard under the Earl of Gloucester attacked but was repulsed; Sir Henry de Bohun was killed by Bruce in single combat. That night, the English camped in a cramped, waterlogged position. On the 24th, Bruce's schiltrons—tight infantry circles with long spears—advanced. English cavalry charges foundered in the marsh and against the spears.

Why it still matters

Bannockburn was a catastrophic English defeat—perhaps 4,000-11,000 English dead, including hundreds of knights, against light Scottish losses. Edward II fled to Dunbar and escaped by sea. The battle secured Scottish independence—though England did not recognize it until the Treaty of Edinburgh-Northampton in 1328. Bannockburn became a central myth in Scottish national identity, demonstrating that infantry could defeat heavy cavalry with discipline and terrain. It established the Bruce dynasty and ensured Scotland remained independent until the 1707 union. The battlefield is now a major heritage site.

Background

Scottish independence aspirations surged afterward. Even centuries later, this episode remains a reference point for how empires rise, fracture, and transform.
