Edward the Black Prince of Cornwall in 1337. He was guardian of the kingdom in his father's absence in 1338, 1340, and 1342. He was created Prince of Wales in 1343 and knighted by his father at La Hogne in 1346. In 1346 Prince Edward commanded the vanguard at the Battle of Crécy, his father intentionally leaving him to win the battle. He took part in Edward III's 1349 Calais expedition. In 1355 he was appointed the king's lieutenant in Gascony, and ordered to lead an army into Aquitaine on a chevauchée, during which he pillaged Avignonet and Castelnaudary, sacked Carcassonne, and plundered Narbonne.
Edward the Black Prince Edward appears to have advanced at the head of the reserve, and the rout soon became complete. When Edward met his son after the battle was over, he embraced him and declared that he had acquitted himself loyally, and the prince bowed low and did reverence to his father. The next day he joined the king in paying funeral honours to King John of Bohemia. The prince was present at the Siege of Calais (1346–1347), and after the surrender of the town harried and burned the country for around, and brought much booty back with him. He returned to England
