Suddenly a man whose face and garb were alike unknown to him, stood before him and asked him why he sat there so mournfully on his seat of stone, while all within the palace were wrapped in sleep. “What is it to thee,” said the weary exile, “where I choose to spend the night?” “But I know,” answered the stranger, “both why thou art here, and why thou art so sad and what thou fearest. Now what wouldst thou give to any one who should free thee from thy anxieties and persuade Redwald not to deliver thee into the hands of thy enemies?” “All that I possess,” said Edwin. “And what if he assured thee that thou shouldst overcome thine enemies and become a king greater than any English king before thee?” “I would give the gratitude which he deserved to any one who could confer on me such benefits.” “And how, if he could point out to thee a new way of life and salvation better than any that thy fathers have known? Wouldst thou hearken to his voice and obey his counsels?” “Assuredly I would,” said Edwin. The stranger put his hand upon his head and said: “When next thou shalt receive this sign, remember what thou hast promised and fulfil it.” With that the stranger, whether he were living man or spirit, zealous missionary or martyred apostle, vanished into the darkness. A little cheered by the vision but still melancholy and anxious, Edwin was sitting yet before the palace when lo! his friend the courtier returned to him with joy in his countenance and said: “Arise, dismiss thy cares, go to thy couch and slumber with a quiet mind. The danger is past. The queen, to whom in secret Redwald disclosed his purpose, persuaded him not for any of Ethelfrid’s gold to sell his far more precious kingly honour, or sacrifice the friend who had sought his protection in extremity.” When day dawned it was seen that Edwin’s friend had spoken truly. The king dismissed Ethelfrid’s messengers with a final refusal, and knowing now that he would have to face that king’s anger, resolved to anticipate the blow and to restore the fugitive to his kingdom. Hastily collecting his army he came upon the surprised and imperfectly prepared Ethelfrid on the banks of the Idle, a little river of Nottinghamshire, and there won a decisive victory. It was true that Redwald’s own son, Regenheri, perished in the fight, but Ethelfrid himself was also slain, and the power of Bernicia for a season annihilated. It was a memorable day for the dwellers in the fens by the Humber, and six centuries later the historian, Henry of Huntingdon, still heard the proverb: “As when the Idle river grew foul with Anglian blood.”
