The earl of Gloucester was not hard to persuade, for he could not bear the shame of the situation. At the same time, loathing delay because his noble country, for the sake of two persons, was being tormented by the plunder and slaughter of civil war, he preferred, if God should allow it, to hazard a final decision. He also hoped for the divine approval in his enterprise, because the king had wronged his son-in-law who was in no way at fault, was besieging his daughter, and had turned into a castle the church of the Blessed Mother of God at Lincoln. How greatly these things must have influenced the prince's mind! Would it not be better to die and fall with glory, rather than bear so signal an affront? So, for the sake of avenging God and his sister, and to free his relatives, he took the risk. The adherents of his party, most of them disinherited men inflamed to war by grief for what they had lost and conscious valour, followed him eagerly, though he cunningly concealed his purpose all the way from Gloucester to Lincoln, keeping the whole army in uncertainty, except for a very few, by taking an indirect route.
The time of decision came on the very day of the Purification of the most blessed Mary [2 Feb.1141], beside the river that flowed between the two armies, named Trent, which was then so much swollen by a heavy fall of rain as well as water from its source that there was no possibility of fording it. Only then did the earl disclose his intention to his son-in-law, who had met him with a strong body of troops, and the rest of his followers, adding that he had long since made up his mind that nothing should ever compel him to retreat; he would die or be captured if he did not win the victory. All filled him with good hope, and so - wonderful to hear - he resolved to risk a battle at once, and swam across the racing current of the river mentioned above with all his men. So eager was the earl to make an end of the troubles, that he would sooner face the final danger than have the kingdom's misfortune prolonged. For the king on his side had broken off the siege and offered battle with spirit, accompanied by very many earls and an active body of knights. The royalists first attempted that prelude to the fight which is called jousting, for in this they were accomplished. But when they saw that the ‘earlists', if the expression may be allowed, were fighting not with lances at a distance but with swords at close quarters and, charging with their banners in the van, were breaking through the king's line, then all the earls to a man sought safety in flight. [Ce adds There were six earls who had entered the battle on the king's side.] A few [Ce Many] barons, of notable loyalty and courage, thinking they should not abandon the king even at this desperate moment, were taken prisoners. The king himself, though he did not lack spirit in self-defence, was at length attacked on all sides by the earl of Gloucester's knights and fell to the ground on being struck by a stone. It is not known who dealt the blow. So, as all around him were captured or put to flight, he brought himself to yield for a time and be held a prisoner. Therefore the worthy earl of Gloucester gave orders that the king should be kept alive and, unharmed, not suffering even that he should be the victim of any insulting language. Behold, he mildly protected in humiliation him whom he had just been furiously assailing when exalted in majesty, so that, controlling emotions of anger and joy, he both showed kindness to a relative and had regard, even in the person of a captive, to the splendour of the crown. But the mass of the citizens [Ce burgesses] of Lincoln was in great part cut down, through the just anger of the victors and without causing any grief to the vanquished, since it was they who by their instigation had given rise to this calamity.
