After conquering his outlawed brother, Tostig, and Harold Hardrada, King of Norway, at Stamford Bridge, he had to hurry back to meet William Duke of Normandy, which he did on a hill on the Sussex Downs, afterwards called Senlac. He closed his life on the field of battle, after a reign of forty weeks and one day. Then the Conqueror had the country at his mercy, but he recognised the importance of London's position, and moved forward with the greatest caution and tact. The citizens of London were possibly a divided body, and William, knowing that he had many friends in the city, felt that a waiting game was the best for his cause in the end. His enemies, led by Ansgar the Staller, under whom as sheriff the citizens of London had marched to fight for Harold at Senlac, managed to get their way at first. They elected Edgar Atheling, the grandson of Edmund Ironside, as King, but this action was of little avail. When William arrived at Southwark the citizens sallied forth to meet him, but they were beaten back, and had to save themselves within the city walls. William retired to Berkhamsted,[13] and is said to have sent a private message to Ansgar asking for his support.[14] In the end the citizens, probably led by William the Bishop, who was a Norman, came over to the Conqueror's side, and the best men repaired to Berkhamsted. Here they accepted the sovereignty of William, who received their oath of fealty. Thus ends the Saxon period of our history, and the Norman period in London commences with the Conqueror's charter to William the Bishop and Gosfrith the Portreeve, supposed to be the elder Geoffrey de Mandeville. In the foregoing pages the main incidents of the history of Saxon London are recited. These are, I fear, rather disconnected and uninteresting, but it is necessary to set down the facts in chronological order, because from them we can draw certain conclusions as to the condition of London before the Norman Conquest. Unfortunately our authorities for the Saxon period do not tell us much that we want to know, and, in consequence, many of the suggestions made by one authority are disputed by another. Still we can draw certain very definite conclusions, which cannot well be the subjects of contention. The first fact is the constant onward march of London towards the fulfilment of its great destiny. Trouble surrounded it on all sides, but, in spite of them all, the citizens gained strength in adversity, so that at the Conquest the city was in possession of those special privileges which were cherished for centuries, never given up, but increased when opportunity occurred. Patient waiting was therefore rewarded by success, and London by the endeavours of her men grew in importance and stood before all other cities in her unique position.
