The bishop fled to Gloucester, where Matilda had assembled the greater number of her adherents. During the absence of Stephen in the east, the flames of revolt were raging throughout the west, and churches as well as castles were fortified by the insurgents for the purposes of defence. The bishops are said not to have scrupled to take part in these military operations: they were seen, as in the time of the Conqueror, mounted on chargers, and clad in suits of mail, bearing a lance or a truncheon in their hands, directing the attacks of the soldiers, and drawing lots for a share of the booty. [Illustration: INTERVIEW BETWEEN THE EMPRESS MATILDA AND QUEEN MAUD. (_See p._ 174.)] In 1141 Stephen displayed the utmost activity in marching against his enemies. After having crossed and recrossed the country, he appeared before the castle of Lincoln, which was in the hands of the adherents of Matilda. The townspeople, however, favoured the king's cause, and, in opposition to the garrison, assisted him to lay siege to the fortress. Meanwhile the Earl of Gloucester had collected an army of 10,000 men, and in the hope of effecting a surprise, marched rapidly to Lincoln, and appeared before the besieging troops. Stephen, however, had been apprised of his coming, and having drawn up his forces in battle array, placed himself at their head. The contest was unequal; most of the royal cavalry deserted to the enemy, and many of the other troops wavered in their allegiance. In such a case defeat was inevitable. Stephen fought with valour, but after having broken his sword and battle-axe, he was made prisoner by the Earl of Gloucester. This defeat was disastrous to the royal cause. Many of the Norman nobles and of the clergy, among whom was Henry of Winchester, the king's own brother, gave in their adhesion to the cause of Matilda. The support of the bishop is said to have been gained by a promise on the part of the empress that he should be placed in the position of her chief minister, and should have the disposal of all the vacant benefices of the Church. On the day after this bargain was concluded, the granddaughter of the Conqueror made her triumphal entry into Winchester. She was received at the gates by Bishop Henry, at the head of the clergy, who conducted her to the cathedral; and the brother of Stephen pronounced a blessing upon all who should follow her cause, and a curse on those who should oppose it.
