Pierre I de Craon

Pierre I de Craon (c. 1315–1376) was the elder son of Amaury III de Craon by Béatrice de Roucy. He fought for Charles de Blois in the Breton Succession War.

At the siege of La Roche-Derrien in 1350, his men lacking ardour, he hung his purse from a pole, promising it to the first soldier into the town, which fell. In 1356 he held Romorantin with Boucicaut against the Black Prince; the town held out until English engineers set up cannon, the first use of artillery in a French siege, and Craon surrendered.

Taken at Poitiers that year, he was among the hostages Edward III demanded for King John II's ransom. With his brother, Archbishop Jean III, and Boucicaut he later negotiated the Treaty of Guérande, which recognised Montfort as Duke of Brittany.
