In the tumultuous 14th century, Scotland’s struggle for independence was marked by countless battles and sieges.
Amidst this chaos, Lady Agnes Randolph, or “Black Agnes,” emerged as a symbol of defiance against overwhelming English forces.
As the English army, led by the Earl of Salisbury, laid siege to Dunbar Castle in 1338, Lady Agnes took command in her husband’s absence, showcasing remarkable strategic acumen and fortitude.
Her cunning tactics and unyielding determination would soon become the stuff of legend, but what drove this extraordinary woman to risk everything, and what was the true cost of her bravery?
The Siege of Dunbar Castle

Someone had to defend Dunbar Castle, a strategic stronghold in southeastern Scotland, when it came under siege in 1338, and Lady Agnes Randolph, also known as ‘Black Agnes,’ was determined to do just that. The castle, situated on a rocky outcrop overlooking the North Sea, was a vital location for the English army‘s invasion of Scotland.
Lady Agnes, the wife of Patrick, Earl of March, took charge of the castle’s defense when her husband was away fighting. The English army, led by the Earl of Salisbury, laid siege to the castle, but Lady Agnes wasn’t intimidated. She rallied the castle’s defenders and organized a strong resistance against the English forces.
The siege lasted for several months, with the English army using various tactics to try and breach the castle walls.
However, Lady Agnes’s determination and strategic thinking kept the defenders one step ahead. She famously mocked the English army’s attempts to breach the walls, even going so far as to dust off the walls with a handkerchief after a failed cannon attack.
Her bravery and cunning ultimately led to the English army’s withdrawal, saving the castle from capture.
Lady Agnes’s Early Life

Born into a prominent Scottish family, Lady Agnes Randolph was raised with the values of strength and resilience that would serve her well in her future defense of Dunbar Castle. As the daughter of Thomas Randolph, 1st Earl of Moray, and Isabel Stewart, Lady Agnes was part of a powerful and influential clan. Her family’s history was marked by loyalty to the Scottish crown, and Lady Agnes was no exception. From a young age, she was taught the importance of duty, honor, and courage, which would become the hallmarks of her later life.
Lady Agnes’s upbringing was typical of a noblewoman of her time. She received an education in domestic skills, such as needlework and household management, as well as in literature and music. Her family’s social status also meant that she was exposed to the politics and intrigue of the royal court.
As she grew older, Lady Agnes became increasingly aware of the tensions between Scotland and England, which would eventually lead to the siege of Dunbar Castle. Despite the challenges that lay ahead, Lady Agnes was well-equipped to face them, thanks to her strong family background and upbringing.
The English Army Arrives

As tensions between Scotland and England continued to escalate, Lady Agnes Randolph’s home, Dunbar Castle, became a focal point for the English army, which, in 1338, arrived at the castle’s gates with the intention of claiming it for their own.
Led by the Earl of Salisbury, the English army was determined to capture the strategic fortress, which controlled the eastern approach to Scotland. The castle’s defenses were strong, with thick stone walls and a commanding position on a rocky outcrop overlooking the sea.
Lady Agnes, aware of the impending threat, had prepared the castle for siege, stocking up on supplies and reinforcing the garrison. The English army, however, wasn’t easily deterred, and they began to lay siege to the castle, hoping to wear down the defenders through sheer numbers and persistence.
The stage was set for a prolonged and brutal conflict, with Lady Agnes at the forefront of the Scottish resistance. Despite being vastly outnumbered, she remained resolute, determined to protect her home and her people from the English invaders.
The siege of Dunbar Castle had begun, and it would be a test of endurance and cunning for both sides.
Black Agnes’s Cunning Tactics

With her castle under siege, Lady Agnes Randolph, now known as Black Agnes, relied on her wit and resourcefulness to outmaneuver the English army, employing cunning tactics to bolster the defenders’ morale and thwart the enemy’s advances.
One of her most effective strategies was to order her men to polish the castle’s armor and weaponry, making it appear as though the defenders were preparing for a massive counterattack. This ruse successfully deterred the English from launching a full-scale assault, instead opting for a prolonged siege.
Black Agnes also utilized the castle’s architecture to her advantage, positioning her archers and crossbowmen in strategic locations to rain down arrows and bolts on the enemy. Moreover, she ordered the construction of makeshift barricades to protect the defenders from the English catapults and trebuchets.
Her tactics not only helped to repel the enemy but also boosted the morale of the defenders, who were inspired by her bravery and ingenuity. As the siege dragged on, Black Agnes’s cunning tactics continued to frustrate the English army, buying valuable time for the defenders and cementing her reputation as a shrewd and fearless leader.
Aftermath of the Siege

The English army’s prolonged siege of Dunbar Castle ultimately ended in defeat, as they withdrew their forces in 1338, having failed to breach the castle’s defenses or capture the indefatigable Lady Agnes Randolph. This outcome was a significant blow to the English, who’d invested considerable resources in the siege. The failure to capture the castle and Lady Agnes, in particular, was a personal embarrassment for King Edward III, who’d hoped to crush the Scottish resistance.
In the aftermath of the siege, Lady Agnes Randolph emerged as a national heroine in Scotland, celebrated for her bravery and cunning. Her defense of Dunbar Castle had thwarted the English army’s plans to conquer Scotland, and her reputation as a skilled military leader was cemented.
The siege also marked a turning point in the Second War of Scottish Independence, as the English army’s defeat at Dunbar Castle weakened their grip on Scotland. The castle itself was left relatively unscathed, a proof of Lady Agnes’s effective defense strategy.
The event was remembered for generations as a symbol of Scottish resistance against English rule, and Lady Agnes’s name became synonymous with bravery and patriotism.
