Reginald de Cobham, 1st Baron Cobham

Reynold (or Reginald) Cobham, 1st Baron Cobham of Sterborough KG (c.1295–1361) was a medieval English knight and diplomat.

Life He was the son of Sir Reynold Cobham by Joan, the daughter and heir of William de Evere. This Reynold was the second son of John de Cobham, by his first wife Joan the daughter of William Fitzbenedict. The family were based at Sterborough Castle, Lingfield, Surrey.

In his early life he was employed on diplomatic missions. By 1334 he was a knight in the household of King Edward III and fought in the Scottish campaign against David de Bruce and then on the continent in the Low Countries and Brittany. During the Siege of Tournai (1340) he held the office of "marshal of the army", a role specific to a particular army and distinct from the hereditary position of Lord Marshal of England. In 1342 he was summoned to the House of Lords as Lord Cobham of Sterborough.

In 1346 he was in the force under Edward III that attacked France, fighting at the Battle of Crécy and the protracted but eventually successful Siege of Calais. In 1352 he was invested as a Knight of the Garter and in 1353 appointed Captain of Calais, a position he held until his death. In 1355 he served under the Edward the Black Prince in Aquitaine, taking part in his march to the Loire and his victory at the Battle of Poitiers, where he was credited by the French historian Jean Froissart with the slaying of the French knight Geoffroi de Charny.

Reynold married Joan Berkeley, a daughter of Thomas de Berkeley, 3rd Baron Berkeley, by whom his descendants could claim to be related to the noble families of Sutton, Dudley, Beauchamp, De Despencer and Mortimer. The Cobham family, however, were well connected to the ruling families of England in their own right.

He died in 1361, probably of the plague, and was laid to rest in an impressive tomb in Lingfield church. He was succeeded by his son Reynold, the second Lord Sterborough.
