Jean de Vienne (1341 – 25 September 1396) was a French knight, general and Admiral of France during the Hundred Years' War.

Early life

Jean de Vienne was born at Dole in the Franche-Comté, then part of the Holy Roman Empire. As a nobleman, he started his military career at the age of 19, and was made a knight at 21. In 1366–1367, he took a part of a Savoyard crusade led by Amadeus VI of Savoy against Bulgaria.

By the age of 24, de Vienne was made Captain-General for the Franche-Comté. In 1373, Charles V made him Amiral de France. Working with determination, de Vienne reorganised the navy, started an important programme of construction, created an effective coast guard and navigation police, organised watches along the coasts, and attributed licences for the building and selling of ships.

Jean de Vienne was one of the first to understand that only by naval operations could serious harm be done to England. To this end he petitioned for strong support from the French monarchy and conducted several expeditions to the Isle of Wight and the southern ports of England.

Between 1381 and 1385, de Vienne fought against the Flemish, notably during the Battle of Roosebeke. In pursuit of his dream of threatening the English at home, in 1385 he used a 180-ship fleet to land an army in Scotland with the intent of invading England; the force successfully besieged Wark on Tweed Castle in Northumberland but eventually had to withdraw. After Charles VI succeeded his father Charles V to the Throne of France, the navy was allowed to decay, since Charles VI did not share his father's concern for naval affairs. Disappointed, de Vienne participated in the Barbary Crusade and joined in the crusade of King Sigismund of Hungary against the Turks. He was killed in Bulgaria at the Battle of Nicopolis in 1396.

Legacy

Several ships of the modern French Navy were named after Jean de Vienne, the most notable of which include:

• The cruiser Jean de Vienne, completed in 1937, scuttled at Toulon in November 1942
• The F70 type frigate Jean de Vienne, completed in 1984, decommissioned in 2019.
