Siege of Wark Castle in 1385

The Siege of Wark Castle in 1385 was a French-led attack on an English fortress that ended in capture, the taking of its household prisoner, and the destruction of the castle itself. The assault exposed the divide between a formidable defensive position and a raiding force without the equipment or time for a conventional siege: the attackers prevailed through repeated assaults and crossbow fire, but could not retain what they had taken.

Setting and Defenses

Castle Wark stood on a rocky outcrop above the Tweed, where its position and fortifications made an attack costly. Its keep rose four stories and had substantial stone vaults around the entrance. Five openings above the approach allowed defenders to drop or fire projectiles down on attackers. Ditches surrounded the castle, slowing anyone advancing toward the walls and leaving them exposed to fire from above.

Sir John Lussebourne held the fortress with his wife and children. Forewarned of the approaching army, he reinforced the garrison and positioned heavy bombards on the walls. Crossbows and cannons added to the defenses of the battlements. The combination of height, ditches, weapons, and a prepared garrison made the castle more than an obstacle along the invaders’ route: it was a position from which defenders could inflict serious losses on troops attempting to climb the walls.

The Assault and Its Constraints

Before the fighting began, Admiral Vienne sent a herald to demand that Sir John surrender or face a siege. Sir John answered from atop the wall with insults and a warning that the admiral should retreat before falling prey to the Scots’ alleged treachery. The exchange ended without surrender, and the assault began.

The French and Scots had advanced as a raiding army, not as a force prepared for a prolonged siege. They had no heavy engines such as a trebuchet, whose stones could be hurled over walls onto roofs. Their portable cannons could not breach the thick stonework. The castle’s foundation on solid rock also ruled out mining beneath the walls, while the need to keep moving left no time to starve out a well-provisioned garrison. Each of these limits removed a safer or slower way of taking the fortress; together, they narrowed the admiral’s options to an attack on the walls.

Vienne ordered an escalade. His men lashed long poles into ladders and sent the bravest attackers up first, with others following close behind. Once the ladders were set against the walls, the assault became close combat on the ascent and at the battlements. Sir John personally engaged French knights climbing the ladders, and the defenders used the height of the walls to make the approach dangerous. Attackers faced boiling liquids, burning sand, quicklime, and bolts from armor-piercing crossbows. A man could fall while climbing in heavy armor, or defenders could thrust a ladder away from the wall with long poles as the climbers neared the top.

Capture and Destruction

The Scots refused to take part in the siege itself, a significant distinction within the combined French and Scottish campaign. French crossbowmen instead took positions around the castle and steadily shot at the English garrison, targeting anyone who appeared above the battlements. The French also renewed their assaults repeatedly. The attackers’ numbers and persistence eventually carried them into the fortress, despite its strong position and the hazards of the climb.

The first French to enter took more than forty prisoners. Sir John, his wife, and their children were among those captured. The account thus makes the fall of Wark both a military defeat and a seizure of the household sheltering within its walls; it does not describe their subsequent fate. The victors then burned and destroyed the castle. They judged that they could neither keep nor guard it, since it lay so far advanced inside England. Capture therefore did not lead to occupation: the fortress was rendered unusable rather than held as a new position.

Place in the Campaign

The siege formed one episode in the French and Scottish advance into England. After marching south from Edinburgh and crossing the Tweed, the army had halted at Wark; the force was described as about five thousand strong. The successful assault opened the way for the invaders to continue south, but the destruction of the castle also shows the limits of what they could secure. They could overcome a defended stronghold under the pressure of a rapid campaign, yet could not remain to guard it.

The episode also establishes a contrast between the two sides’ methods and circumstances. The garrison relied on fixed defenses, prepared weapons, and the protection of the castle’s height and ditches. The attackers, lacking siege engines and time, relied on numbers, repeated ladder assaults, and crossbowmen surrounding the walls. Wark’s fall did not result from a breach made by heavy machinery or from the defenders being starved into surrender; it followed an exposed, repeated assault that finally succeeded, after which the attackers destroyed the place rather than try to hold it.
