This victory brought the rebellion in England to an end. On hearing the news Henry marched against the castle of Huntingdon, which had been for some time besieged, and it at once surrendered. There his natural son Geoffrey, who had been made Bishop of Lincoln the summer before, joined him with reinforcements, and he turned to the east against Hugh Bigod. A part of the Flemish force which was expected had reached the earl, but he did not venture to resist. He came in before he was attacked, and gave up his castles, and with great difficulty persuaded the king to allow him to send home his foreign troops. Henry then led his army to Northampton where he received the submission of all the rebel leaders who were left. The Bishop of Durham surrendered his castles and gained reluctant permission for his nephew to return to France. The king of Scotland was brought in a prisoner. The Earl of Leicester's castles were given up, and the Earl of Derby and Roger Mowbray yielded theirs. This was on the last day of July. In three weeks after Henry's landing, in little more than two after his sincere penance for the murder of St. Thomas, the dangerous insurrection in England was completely crushed,--crushed indeed for all the remainder of Henry's reign. The king's right to the castles of his barons was henceforth strictly enforced. Many were destroyed at the close of the war, and others were put in the hands of royal officers who could easily be changed. It was more than a generation after this date and under very different conditions that a great civil war again broke out in England between the king and his barons.
