Jeanne Hachette ('Joan the Hatchet'). She was the daughter of a peasant and is known for an act of heroism on 27 June 1472, when she prevented the capture of her town by the enemy troops of Burgundy. The town was defended by only 300 men-at-arms.

The Burgundians were making an assault, and one of their number had actually planted a flag upon the battlements, when Jeanne, axe in hand, flung herself upon him, hurled him into the moat, tore down the flag, and revived the drooping courage of the garrison. 

Here's more detail about her and the women who fought side by side with the men to defend their city.

In June of 1472 Charles the Bold, Duke of Burgundy, laid siege to the French town of Beauvais. Over the course of the three week siege, a peasant woman named Jeanne Laisne joined a contingent of women and children responsible for loading the town’s cannons, delivering munitions and dumping boiling liquid over the walls onto the attackers.

By 27 June, many of the French defenders had lost hope and begun to flee as an assault from the Burgundians seemed set to defeat the town. An officer was about to plant the Burgundian flag on the wall and claim Beauvais when Jeanne grabbed a hatchet and flung herself upon him, hurling him off the wall and tearing down the flag. Her bravery revived the courage of the garrison and the French soldiers returned to their posts, keeping the Burgundians at bay until reinforcements arrived and the town was saved.

By way of recognition, King Louis XI heaped favors on Jeanne and ordered for the ‘Procession of the Assault’ to take place in Beauvais every year with women marching at the head of the parade. This tradition still continues.

In 1851, a bronze statue sculpted by Gabriel-Vital Dubray was unveiled in Beauvais by Louis-Napoleon Bonaparte.
