Some of the attendants of the commissioners, who had come with them from France, made their escape, and, returning to Paris, they reported to the King of France all that had occurred. It now came his turn to be angry, and both parties began to prepare for war. The King of England took sides with his son, and so was drawn at once into the quarrel. Various military expeditions were fitted out on both sides. Provinces were ravaged, and towns and castles were stormed. The Prince of Wales was overwhelmed with the troubles and perplexities which surrounded him. His people were discontented, his finances were low, and the fortune of war often turned against him. His health, too, began to fail him, and he sank into a state of great dejection and despondency. To complete the sum of his misfortunes, his oldest son, Richard's brother, fell sick and died. This was a fortunate event for Richard, for it advanced him to the position of the oldest surviving son, and made him thus his father's heir. It brought him, too, one step nearer to the English throne. Richard was, however, at this time only four years old, and thus was too young to understand these things, and probably, sympathizing with his father and mother, he mourned his brother's death. The parents, at any rate, were exceedingly grieved at the loss of their first-born child, and the despondency of the prince was greatly increased by the event. At last the physicians and counselors of Edward advised that he should leave his principality for a time and repair to England. They hoped that by the change of scene and air he might recover his spirits, and perhaps regain his health. The prince resolved on following this advice. So he made arrangements for leaving his principality under the government and care of his brother, John of Gaunt, and then ordered a vessel to be made ready at Bordeaux to convey himself, the princess, and Richard to England. When every thing was ready for his departure, he convened an assembly of all the barons and knights of his dominions in a hall of audience at Bordeaux, and there solemnly committed the charge of the principality to his brother John in the presence of them all. He said in the speech that he made to them on that occasion, that during all the time that he had been their prince, he had always maintained them in peace, prosperity, and power, so far as depended on him, against all their enemies, and that now, in the hope of recovering his health, which was greatly impaired, he intended to return to England. He therefore earnestly besought them to place confidence in, and faithfully serve and obey, his brother, the Duke of Lancaster, as they had hitherto served and obeyed him. The barons all solemnly promised to obey these injunctions, and they took the oath of fealty and homage to the duke. They then bid the prince farewell, and he soon afterward embarked on board the ship with his wife and son, and set sail for England.
