Combat of the Thirty, episode of the Hundred Years’ War fought on March 27, 1351, in the struggle for the succession to the duchy of Brittany between Charles of Blois, supported by John II, the king of France, and John of Montfort, supported by Edward III, the king of England.
Whereas most battles are usually fought by large numbers of combatants, the Combat of the Thirty was waged by only thirty knights on each side. Although a minor encounter in the larger context of the war, the combat is remembered as one of the most chivalrous battles in history.
From 1341 to 1364, the succession to the duchy of Brittany was contested between the rival houses of Blois and Montfort. A truce arranged by Jean de Beaumanoir, governor of Brittany and a supporter of Blois, was being ignored by Sir Robert Bramborough, the captain of Ploërmel and a supporter of Montfort. Beaumanoir issued a challenge that thirty knights and squires on each side should decide the matter in battle, midway between their two castles of Josselin and Ploërmel, about 8 miles (12.8 km) apart. Beaumanoir commanded an all-Breton detachment, while Bramborough led a mixed force of twenty Englishmen, six German mercenaries, and four Bretons. The battle, fiercely fought by soldiers either mounted or on foot, was waged with lances, swords, daggers, and maces; it was reminiscent of the last fight of the Burgundians in the Nibelungenlied, especially in the advice of Geoffroy du Bois to his wounded leader, who was asking for water: “Drink your blood, Beaumanoir; that will quench your thirst!” That admonition did not stop the opposing forces from stopping after a time to refresh themselves with wine and food, bandage wounds, and rest for a short while before resuming the combat.
Victory finally came when Guillaume de Montauban, a squire fighting for Beaumanoir, mounted his horse and overthrew seven English horsemen. Casualties were heavy on both sides, but Bramborough’s force suffered a higher loss of life and surrendered after his death. All the prisoners were treated well and were released promptly on the payment of a small ransom.
Recorded by both the Flemish writer Jean Le Bel and the French historian Jean Froissart, neither of whom was present, the Combat of the Thirty remains one of the best-known engagements of the Hundred Years’ War. The impact of the fight on the issue of Breton succession was limited—the house of Montfort eventually won—but contemporaries considered it to be one of the finest examples of chivalry yet displayed.
Losses: Franco-Breton, 2 of 30 soldiers; Anglo-Breton, 9 of 30.
