Henry II, who had been in Normandy fighting his enemies, landed in England on 8 July. His first act was to do penance for the death of Thomas Becket, who was murdered by some of Henry's knights three years earlier and had already been canonized as a saint. The day following the ceremony at Canterbury, on 13 July, in a seeming act of divine providence for Henry II, William the Lion and many of his supporters were surprised and captured at the Battle of Alnwick by a small band of loyalists. In the aftermath Henry II was able to sweep up the opposition, marching through each rebel stronghold to receive their surrenders. With England taken care of, Henry returned to Normandy and set about a settlement with his enemies, and on 30 September "King Henry, the king's son, and his brothers, returned to their father and to his service, as their lord".
