Jeanne de Clisson: The Lioness of Brittany
Chapter 3

The Oath at the Gate

Staring up at her husband's severed head, Jeanne refuses to retreat into aristocratic mourning. Instead, she sells her vast estates and buys an army.

The August heat baked the city of Nantes, bringing with it a thick, sweet, sickening smell. Flies buzzed in furious, swirling clouds around the high stone archway of the Sauvetout Gate. They clustered on the iron spike protruding from the masonry, and on the decomposing head packed in salt that was mounted upon it.

Beneath the archway, the city bustled. Merchants, soldiers, and peasants hurried through the shadow of the gate, keeping their eyes firmly on the cobblestones. No one wanted to look up at the King’s justice. No one wanted to look at what remained of Olivier IV de Clisson.

But Jeanne de Clisson did not look away.

Standing in the center of the thoroughfare, wrapped in a dark cloak, the forty-three-year-old Lioness of Brittany stared up at the mutilated face of her husband. Her high, domed forehead and sharp, intense eyes were locked on the iron spike. She had shed every ounce of her former aristocratic poise. In its place was a terrifyingly methodical stillness—the bearing of a woman who had calculated the exact cost of the world, and decided to burn it down.

She was not alone. She gripped the shoulders of her two young sons, forcing them to stand directly beneath the horror.

Five-year-old Guillaume de Clisson buried his face in his mother's dark skirts. Small, fragile, and innocent, he was dressed in a miniature, finely woven blue tunic that belonged in a sheltered nursery, not a slaughterhouse. He was a soft thing brought to a hard place, weeping quietly into the heavy wool.

Beside him stood seven-year-old Olivier V. Wide-eyed and shivering despite the summer heat, the boy was swaddled in an oversized, heavy cloak. He stared up at the spike, his small chest heaving. He was absorbing a trauma so absolute that it would eventually curdle him into the most ruthless, heavily scarred commander in France—a man who would one day be known simply as "The Butcher."

Jeanne’s grip tightened on their shoulders. Her voice, when she finally spoke, was dry as ash.

"Do not look away," she whispered.

Young Olivier flinched, but he kept his eyes on the gate.

"Remember what they did," Jeanne commanded, her voice rising just enough to cut through the hum of the city. "Remember the King’s justice. Remember Charles de Blois, who whispered the lies. You will swear it to me now. We do not mourn. We collect what we are owed."

Because Jeanne’s desperate attempt to bribe the royal guards in Paris had failed, King Philip VI had legally condemned her as a traitor. A French court issued the decree: she was banished, and her vast Breton estates were forfeit to the Crown.

But a 14th-century royal decree moved at the speed of a horse, and enforcing it took an army of slow-moving bureaucrats. Jeanne moved faster.

Before the royal ink had even dried on the confiscation orders in late 1343, Jeanne de Clisson went to work. She was a woman who had managed complex coastal trade routes and massive estates; she knew how money moved. She rapidly liquidated everything the Crown had not yet physically seized. She sold off hidden land deeds, unseized manors, heavy oak furniture, and velvet finery. She emptied her jewelry boxes of gold and pearls, turning a lifetime of aristocratic privilege into hard, cold coin.

With that massive war chest, she bought an army.

Jeanne bypassed the unreliable feudal levies of the era and hired mercenaries. She raised a highly disciplined, fiercely loyal force of four hundred men. These were veterans who respected the Clisson gold and feared the cold rage of the widow paying it.

By the winter of 1343, Jeanne had traded her tailored silken cotehardies for practical, heavy linen and a dark woolen jupon. The litigious noblewoman was gone. The warlord had arrived.

She launched a localized, brutal guerrilla campaign against pro-French strongholds in the Breton marches. For months, she struck isolated garrisons, bleeding the forces of Charles de Blois. But four hundred men cannot win a war of attrition. Jeanne needed a victory that would shatter the illusion of French control.

She found it at the Château de Touffou.

The Trap Springs

Early in 1344, the deep winter chill still clung to the dark forests surrounding Touffou. The castle was a formidable French stronghold commanded by Galois de la Heuse, a French officer who had once been a friend and comrade to Olivier de Clisson before the war fractured their loyalties.

Galois stood on the high stone battlements, his breath pluming in the freezing air, looking down at the edge of the treeline.

A small party had emerged from the forest. No more than forty men, shivering in the cold, escorting a lone woman on horseback. Galois squinted through the morning mist, recognizing the high forehead and the familiar Clisson crest on the saddle housing.

It was Jeanne.

To a 14th-century military commander, a dispossessed widow arriving at his gates with a meager forty-man escort signaled one thing: surrender. Galois assumed Jeanne was exhausted, freezing, and seeking shelter from the winter. Chivalry, and the memory of her late husband, demanded he show mercy.

"It is the Lady Jeanne!" Galois shouted down to his men in the gatehouse. "Lower the bridge! Open the gates!"

The massive wooden drawbridge groaned on its iron chains, slamming down across the moat with a heavy thud. The iron portcullis cranked upward into the stone archway.

Jeanne rode forward, her face obscured by the hood of her dark cloak. She crossed the wooden planks of the drawbridge. Galois descended to the courtyard to meet her, expecting tears and supplication.

Instead, Jeanne reached beneath her cloak and drew a hunting horn.

She raised it to her lips and blew a single, piercing note that shattered the quiet of the morning.

The forest erupted.

One Survivor
The story goes that Jeanne left exactly one survivor alive to carry her warning to the King.

From the dense, snow-dusted treeline, the remaining three hundred and sixty mercenaries of Jeanne’s army burst from their hiding places. They surged across the open ground with terrifying speed, heavily armed with falchions, spears, and crossbows. Before the shocked French guards could even begin to turn the crank to raise the bridge, Jeanne’s vanguard hit the gatehouse.

Jeanne dropped her heavy cloak, revealing the padded armor and steel beneath. She spurred her horse forward into the courtyard, her men pouring in behind her like a flood of dark water.

The fighting was entirely one-sided. It was not a battle; it was an execution. Galois de la Heuse’s garrison of eighty men was caught completely unawares. Swords rang against stone, shouts of panic were cut short by the wet thud of crossbow bolts, and the snow in the courtyard rapidly turned a slick, steaming crimson.

Jeanne’s mercenaries swept through the corridors, the barracks, and the armory, slaughtering the garrison with absolute, uncompromising efficiency.

When the screaming finally stopped, the Château de Touffou belonged to the Lioness of Brittany.

The story goes that as the smoke cleared over the butchered courtyard, Jeanne walked among the dead until she found a single, trembling French soldier hiding behind a wagon. Instead of ordering his throat cut, the legend claims she looked down at the terrified man and told him to run. She deliberately left exactly one survivor alive to travel back to Paris and whisper to King Philip VI that his nightmare had begun.

Whether she spared one man or none, the message reached the Crown all the same. The capture of Touffou was a spectacular tactical victory.

But it was also a mathematical trap.

As the blood cooled on the stones of Touffou, Jeanne looked out from the battlements her men had just secured. Four hundred mercenaries were enough to take a castle by surprise. They were nowhere near enough to hold one.

On the horizon, a massive dust cloud was already rising above the winter roads. The slaughter at Touffou had finally provoked the full, terrifying weight of the French Crown. The royal army had mobilized, and thousands of heavily armored cavalry were now marching directly on her position.
