Louis de Sancerre

Louis de Sancerre (1341 or 1342 – 6 February 1404) was a Marshal of France and Constable of France during the Hundred Years War.

Sancerre was born as the second son of count Louis II de Sancerre and Béatrix de Roucy. His father was killed at the battle of Crécy in 1346. After the death of his father King Philip VI of France ordered him to be educated together with the children of the Duke of Normandy. Sancerre had his first experience in war during the Siege of Melun in 1359, where he gained the nottice of Bertrand du Guesclin.

When Charles V of France became King, Sancerre served in the conquest of Guyenne. The King made him a Marshal of France on 20 June 1368 with the order to protect Paris. In 1369 Sancerre surprised and forced the Earl of Pembroke to retreat to Puyrenon. He aided du Guesclin in winning the Battle of Pontvallain. During the next years, Sancerre fought the English in the Limousin, Languedoc and Guyenne. In 1375 Sancerre captured Cognac and Saint-Sauveur-le-Vicomte. He fought against the Tard-Venus and against the local lords in the Auvergne who had taken to brigandage. In 1377 Sancerre was campaigning again in Guyenne and he took part in the siege of Bergerac, where he distinguished himself in capturing several local lords. After the death of du Guesclin both Coucy and Sancerre were offered the post of Constable but refused. Barbara Tuchman postulated that they both refused the office because they knew the King was ailing and a regency under the Dukes of Anjou, Berry and Burgundy was coming and they didn't want the political enmity the function brought with it.
