From Pevensey, William marched to Hastings, and ravaged the country for provisions, constructing at the same time a wooden fort as a secure basis of operations. Harold was at York when he received the intelligence of the landing of the Norman host, and he made hot haste to London, whence he issued a summons to all the men of England to come to his aid against the invader.
But in the supreme hour of the fortunes of the English kingdom, it was found that the old disunion which the kings of Wessex had in vain attempted to overcome, was still as potent a factor for evil as in the days of the Danish invasions. From Wessex, and from the earldoms of Harold's brothers, men readily came to defend the fatherland; but Edwin and Morcar, with a short-sightedness and ingratitude which are almost incredible, kept back the men of the North, under the expectation that William, if he overcame, would be content with Wessex and the South, and that so the house of Leofric would profit by the overthrow of the house of Godwin.
Harold abode in London for six days, gathering his host together, and entered into negotiations with Duke William. That there was any sincerity on either side may be doubted, and probably the first proposal, which was sent apparently by Harold, was only made to gain time. It is said that William was offered a sum of money to depart. To this William replied by a series of clever propositions, of which the first was that Harold should give up the kingdom in exchange for the earldom of Northumberland, an offer which, if made, shows that the Norman duke by no means felt the ground to be safe under his feet. Then he is related to have appealed to the mediation of the Pope, a tolerably safe proposal, considering his previous dealings with the Holy See. Lastly, he is said to have challenged Harold to single combat, an offer which the king likewise declined, on the ground that this was not a mere personal quarrel, but a matter in which the whole English nation was concerned.
By the end of six days, Harold had collected a considerable force, and determined to risk a battle, and a consideration which influenced him not a little was the difficulty of provisioning so large a host without causing annoyance to the people. Here, as on previous occasions in his career, Harold was actuated by motives of humanity; but it may be doubted whether it would not have been wise to wait for more levies, and then overwhelm the Normans, who, man for man, were far better warriors than the English, by sheer numbers. He advanced, however, southwards, and halted on a hill called Senlac, to the north-west of Hastings.
The position was a very strong one, and Harold, with great military skill, fortified it with a palisade, thereby making a most formidable barrier against the Norman cavalry. The battle of Senlac, or Hastings, as it is popularly called, was fought on the 14th of October, and the evening before it was spent, it is said, by the Normans in prayer, and by the English in drinking and the singing of songs.
The battle began about nine o'clock. The English host was marshalled behind the palisade, all on foot, for they, unlike the Normans, were never fond of fighting on horseback, and Harold, with his brothers Gurth and Leofwine, stood under the royal standard. Against them the Normans advanced in three divisions, of which William commanded the centre. On the left was Alan of Brittany, with a force of Bretons, and troops from Maine and Poitou; on the right was Roger of Montgomery, at the head of the mercenary troops, whom William had hired from wherever they could be collected. The first attack failed completely, and the Normans, after a vain attempt to break down the palisade, were driven back in confusion, the Bretons being the first to fly. Unfortunately, in their excitement, some of the English soldiers pursued beyond the palisade, and were easily cut down in the plain. In the second attack, William of Normandy was unhorsed by Earl Gurth, but went against him on foot and cut him down; about the same time Leofwine was also slain.
Still, the English barrier was intact, and it seemed as if the Normans must withdraw in discomfiture. But William's generalship was equal to the occasion. He had seen how helpless the English were upon the open plain, and he resolved, therefore, to lure them from behind their defences by a feigned flight. The ruse was successful, and a considerable portion of the English army suffered for disobedience of Harold's orders by being compelled to make their escape as best they could to the broken ground to the back of the hill.
Still Harold fought on, and as evening was coming on, it seemed as if he might even yet be able to hold the field. Then William bethought him of another plan, and ordered his archers to shoot into the air, whereby the English were seriously incommoded. One of the falling shafts pierced Harold through the eye, and he was mortally wounded. The battle was to all intents ended when he died; his house-carls were killed at their posts, the light-armed troops fled into the rocks and swamps, inflicting severe losses upon such of their enemies as ventured to pursue them.
Thus did William of Normandy win the great battle of Hastings, which lasted from sunrise to sunset, and which, for the valour displayed by both armies and their leaders, was worthy to decide a contest for a crown. William, in the course of the battle, had three horses killed under him, and lost nearly fifteen thousand men; the loss of the English was probably considerably more.
William, at the height of his success, gave orders for the whole army to fall on their knees, and return God thanks for so signal a victory; after which he caused his tent to be pitched on the field of battle, and spent the residue of the night among the slain. Not less perhaps in gratitude for the past, than in the hope that such a work would procure him heavenly favour for the future, he solemnly vowed that he would erect a splendid abbey on the scene of this his first victory; and when this vow was accomplished, the altar of the abbey church stood on the spot where the standard of Harold had been planted. The holy house thus founded was called Battle Abbey.
