Shortly after his return to England a great tournament was held by him at Windsor in memory of King Arthur. In 1346 he set sail on the expedition which resulted in the great victory of Crecy[15] and the capture of Calais. It was a strong place, and the inhabitants had done much harm to the English and Flemings by their piracies. He built a regular town before the walls, sent for a fleet to blockade the harbor, and laid siege to the town with about thirty thousand men. Meanwhile the Scots, who at Philip's instance had invaded England, were routed at Neville's Cross, Durham, on October 17, and King David was taken prisoner and confined in the Tower. In April some stores were brought into Calais by sea, and after this Edward ordered a stricter blockade; his fleet dispersed a convoy of forty-four ships laden with provisions on June 25, and the next day a letter was intercepted from the governor to the French king informing him of the starving condition of the garrison, and asking for relief. Edward sent the letter on to Philip, bidding him come to the relief of the town. In July Philip led an army toward Calais. A portion of it sent to dislodge the Flemings, who were acting with Edward at Quesnoy was defeated. He appeared at Sangatte on the 27th. He was unable to get at the English who were securely posted behind the marshes, and challenged Edward to come out to battle. It is said that Edward declared that he accepted the challenge; but it is probable that he answered more wisely. Anyway, two days later, on August 2, the French decamped. The next day the town surrendered at discretion. The garrison came forth with swords reversed, and a deputation of the townsmen with bare heads and ropes about their necks, prostrated themselves before Edward, offering him the keys of the city. He at first intended, or made as though he intended, to put the inhabitants to the sword as a punishment for their piracies, but spared them at the intercession of his queen. During the summer his army suffered much sickness, arising from lack of good water. With some few exceptions he banished the people of Calais; and sent over to England offering grants and privileges to those who would colonize the town. After agreeing to a truce for nine months, he returned home with his wife and son, and after a stormy passage, landed at Sandwich on October 12. All England was filled with the spoils of Edward's expedition, so that there was not a woman who did not wear some ornament, or have in her house fine linen or some goblet, part of the booty the king sent home from Caen or brought back from Calais.
