About Jeanne de Nevers

Joanna of Flanders (c. 1295 – September 1374), also known as Jehanne de Montfort and Jeanne la Flamme, was consort Duchess of Brittany by her marriage to John IV, Duke of Brittany. She was the daughter of Louis I, Count of Nevers and Joan, Countess of Rethel, and the sister of Louis I, Count of Flanders. Joanna organized resistance and made use of diplomatic means to protect her family and her country. In the siege of Hennebont, she took up arms, dressed in armor, and conducted the defence of the town. She eventually led a raid of soldiers outside the walls of the town and demolished one of the enemy's rear camps. She was an earlier patron for women, and a possible influence to Joan of Arc.

In the siege of Hennebont by Charles of Blois in 1342, she took up arms and, dressed in armour, conducted the defence of the town, encouraging the people to fight, and urging the women to "cut their skirts and take their safety in their own hands". When she took a look from a tower and saw that the enemy camp was almost unguarded, she led three hundred men on a charge, burned down his supplies and destroyed his tents. After this she became known as "Jeanne la Flamme". Charles of Blois tried to starve the people in Hennebont. During a long meeting the bishop of Leon tried to persuade Joanna to surrender, but from the window she saw the ships of Sir Walter Manny's ships from England sailing up. Hennebont was strengthened with English forces and held out.
