On this day On this day in 1314, the Battle of Bannockburn began. Over two days, King Robert’s Scottish army defeated the numerically superior English one led by Edward II. The Scots' victory cemented Robert's control over Scotland and became a defining moment in the Wars of Independence

Robert the Bruce had spent years reclaiming castles and territory lost to the English, steadily consolidating his power after a long period of exile and defeat. By now, he had begun demanding the allegiance of former supporters of King John Balliol, threatening confiscation of lands for those who refused.

The last major stronghold still in English hands was Stirling Castle, held under siege by Robert’s younger brother, Edward Bruce. An agreement had been made: if the English did not relieve the garrison by Midsummer’s Day, the castle would surrender. Determined not to lose this key fortress, Edward II marched north with a massive army (estimated at between 20,000 and 25,000 men)to confront King Robert and his Scottish forces, who numbered closer to 6,000. Though outnumbered, Bruce’s army was battle-hardened and disciplined, largely composed of spearmen trained in tightly packed schiltron formations.

Despite the long trek from the south, Edward pressed his troops onward, forcing them to march seventy miles in one week. The result was exhaustion with horses, horsemen, and infantry alike were worn down by toil, hunger, and poor planning. Bruce, by contrast, was well-positioned and prepared. His key commanders included:

  1. Edward Bruce, his brother and commander of the siege at Stirling.
  2. Thomas Randolph, Earl of Moray and the Bruces' nephew.
  3. Sir James Douglas, Lord of Douglas, who held joint authority with the young Walter the Steward. Walter was a rising figure in the war, who would later marry Bruce’s daughter, Marjorie, and father Robert II, the first Stewart king.

During the battle, Robert the Bruce famously killed Sir Henry de Bohun in single combat, cleaving his skull with an axe after sidestepping the English knight’s charge. Though the skirmish was small in scale, it provided a symbolic and morale-boosting moment for the Scottish army. That night, Sir Alexander Seton, a Scottish noble serving in Edward II’s army, defected and warned Bruce that the English camp was disorganized and demoralized. Seton urged the king to seize the opportunity for a decisive victory.

Bruce acted boldly. On June 24, he launched a full-scale assault, deploying his schiltrons not as static defensive circles but as mobile, offensive units; a tactic he had rigorously trained them for. The terrain favored the Scots: Bruce drew the English army into marshy ground hemmed in by the Bannock Burn and Pelstream Burn, where their cavalry and archers were rendered ineffective. The Scots advanced steadily, their tightly packed formations withstanding and repelling repeated English charges. As panic spread, the English lines collapsed. Realizing the battle was lost, Aymer de Valence, Earl of Pembroke, led Edward II from the field to ensure the king’s survival despite Edward’s protests.

Several high-ranking English nobles were killed or captured. Among the dead were Gilbert de Clare, 8th Earl of Gloucester and Edward II's cousin, and Robert Clifford, a senior commander. Humphrey de Bohun, 4th Earl of Hereford and Edward’s brother-in-law, was taken prisoner and later exchanged for Bruce’s wife, sisters, and daughter, who had been held in English captivity for years.

As the English army broke and fled, Sir James Douglas led a mounted pursuit. Edward II escaped to Dunbar Castle, from which he took ship to Berwick. The remnants of his army attempted to retreat south across the border (over 140 km away) but were harried by Scottish forces and hostile locals. Many were killed; few made it home. Historian Peter Reese wrote that "only one sizeable group of men—all foot soldiers—made good their escape to England."

The Battle of Bannockburn did not end the war, but it secured Bruce’s control of the Scottish kingdom and crippled English morale. It became one of the most iconic victories in Scottish history. A defining moment of national pride, resilience, and defiance.

was there a problem in the english command Structure?

Edward II having a weak control over his army( not being able to control his nobles )?

I think I read somewhere that Gilbert de Clare, 8th Earl of Gloucester and Humphrey de bohun was fighting with each other.

They refused to work together. Gilbert was the commander, but Humphrey saw himself as above him. Beacuse he wss the constable of England.

And this made the chain of command confusing.

You’re completely correct! There were major issues in the English command structure. Edward II probably wasn’t exactly the most inspiring leader, especially when comparing him to his father, and the English relied heavily on their sheer numbers. Edward II seemed to have expected brute force to work and underestimated the Scots, despite their tactical advantages and strong defensive position.

Like sure, on paper the larger army seems good, but Edward reportedly ignored advice from more seasoned commanders and refused to adapt when things began going wrong. No clear plan of engagement was laid out, and the army simply blundered forward into unfavorable terrain. Pair that with the English army already being exhausted before the battle?

Edward II was nominally in charge, but he lacked the charisma and authority to effectively coordinate his nobles, especially figures like Humphrey de Bohun, Earl of Hereford, and Constable of England, Gilbert de Clare, Earl of Gloucester, and Aymer de Valence, Earl of Pembroke. Hereford and Gloucester were powerful magnates with a history of not getting along, and they absolutely refused to defer to one another despite Gloucester being the king’s nephew (his mother was Joan of Acre, Edward II’s sister) and technically in charge of the vanguard. Aymer, an experienced commander, was marginalized by Edward beforehand, probably because of his past involvement in Gaveston’s exile.

As you said, Hereford technically outranked Gloucester though, in terms of traditional military prestige. I believe Hereford was furious that Gloucester was given command over him. As Constable of England, he believed it was his right in addition to him having more experience. Though because of the Piers Gaveston fiasco a couple years earlier which saw Humphrey side against the king on the matter, Humphrey had been out of favour with Edward and that’s probably why he didn’t get the position. Apparently Hereford and Gloucester argued about it just before the battle too.

On the second day of the battle, apparently Gilbert de Clare tried to suggest the battle be postponed after the first day went poorly. King Edward accused him of cowardice. Gilbert was offended and led a charge against the Scots only to be quickly surrounded and killed.

Edward II also failed to enforce a clear hierarchy, and his inability to manage egos meant that critical military decisions were delayed, contested, or executed poorly. The only thing that was cohesive (somewhat) was the retreat, and that was organized by Aymer de Valence.

While Robert Bruce had a smaller army, it was tightly coordinated, highly mobile, and led by a unified command he knew exactly who was in charge and who to trust. The only arguably weak link was Walter the Steward because he was much younger than the other men, but Robert had him with James Douglas for that very reason.

This is the most complete answer. Edward was just not brilliant at commanding an army, Robert the Bruce was, and tbf even really really good generals (E3, H5) made mistakes in their early battles. I only came to say less well what you did, my only addition is Edward was never good at this (said with love, Robert was good at it and most of us wouldn’t be brilliant at commanding an army!)

Apocryphal or otherwise, the story about The Bruce soloing Henry de Bohun, whilst under armoured and unprepared, is one of the most badass moments in Scottish history.

Gilbert de Clare was Edward II's nephew, not his cousin, and his death arguably kicked off Edward II's downfall, as the massive Clare inheritance was eventually contested between the husbands of Gilbert's sisters. That led to the Despenser Wars, which led to the Despenser's tyranny and ultimately the Isabella-Mortimer invasion.

Bannockburn is also where Roger Damory first came to Edward II's attention for his valor.

Gilbert de Clare was Edward II's nephew, not his cousin

I realized my error after posting! That's my mistake.

The English failed to utilized their longbowmen successfully and the Scottish cavalry eventually drove them off the field. Longbowmen proved highly effective against Scottish schiltrons at Falkirk, without them the English cavalry could not break through the tightly packed Scottish lines.
