The Surrender of Nantes and the Imprisonment of John of Montfort (November 2, 1341)

Following the disastrous defeat at Nantes, John of Montfort lost the last vestiges of support within the city. The irate city council, frustrated by his failures and unwilling to endure further losses, forced him to surrender on November 2, 1341.

John of Montfort’s Forced Capitulation

• After suffering multiple military setbacks, including the loss of Champtoceaux and the failed defense of Nantes, Montfort’s position was untenable.
• The Nantes city council, exhausted by the siege and angry at his leadership, compelled him to surrender.
• Recognizing the futility of further resistance, Montfort accepted the terms of surrender.

Safe Conduct and Betrayal

• Montfort was offered safe conduct to negotiate a settlement with Charles of Blois, his rival for the Duchy of Brittany.
• However, these negotiations proved fruitless, as neither side was willing to compromise on their claims.
• With no diplomatic resolution in sight, Montfort was arrested and imprisoned in the Louvre in Paris, under orders from Philip VI of France.

Consequences and Impact

• With Montfort imprisoned, his cause seemed lost, and Charles of Blois strengthened his control over Brittany.
• However, Montfort’s wife, Joan of Flanders, refused to accept defeat. She would later lead the resistance in his name, securing English military aid to continue the war.
• Montfort’s imprisonment did not end the Breton War of Succession (1341–1365), as England’s eventual involvement would transform Brittany into a key battleground in the Hundred Years’ War.

The fall of Nantes and the capture of John of Montfort in November 1341 marked a major turning point in the Breton War of Succession, but it was far from the end of the conflict, as Joan of Flanders and English intervention would soon shift the balance.
