Meanwhile, the king's friends were not idle in the west. Walter de Lacy, a Norman baron, and Eghelwig, the Saxon abbot of Evesham, roused the people of the country to take arms against Roger Fitzosborne and his Welshmen; and the people, regarding the Welsh as their natural enemies, obeyed the call of Walter and Eghelwig, and crowded to the royal standard.

At length the royal soldiers and the insurgents met face to face. It was on the banks of the Severn that the hostile armies encountered and fought a sanguinary battle. The Welsh, however, were defeated, and with such slaughter that the river was crimsoned with their blood. Roger Fitzosborne was made prisoner, and with him many adherents were taken with arms in their hands. The chief was kept in secure custody till the Conqueror should decide what was to be his fate. But the inferior captives were summarily disposed of. Some were hung on gibbets, some had their eyes put out, and others underwent such mutilation as to render them incapable of further mischief.

While such disasters attended the adventure of Roger Fitzosborne on the Severn, Ralph de Gael did not yield to the temptation of lingering with his fair bride at Norwich. Leaving that city, the bold Breton encamped in the neighbourhood of Cambridge, and succeeded in alluring a multitude of Saxons to his standard. But Ralph de Gael's part of the enterprise proved little more successful than that of Roger Fitzosborne had been. While the Breton earl was still gathering men to his camp, William de Warren, with Odo, Bishop of Bayeux, and Geoffrey, Bishop of Coutance, took the field, and the insurgents found themselves menaced by a force decidedly superior to them in number. Not shrinking, however, from a conflict, they bravely faced the royal force at a place named Fagadon. There a stubborn battle was fought; but Ralph de Gael's men were completely defeated; and the chief escaped from the lost field, while many of his adherents were taken and treated with the utmost cruelty. Indeed, the victors are said to have been so merciless as to cut off the right foot of every captive, no matter what his rank or nation.

In the midst of this operation, Ralph de Gael had the fortune to reach Norwich. He threw himself into the citadel with some vague and desperate notions of defending himself to the last. Seeing, however, the impossibility of holding out, he left the fortress under the charge of his bride, and sailed to Brittany to implore the aid of his friends. The daughter of Fitzosborne made a brave defence, but her resistance proved vain. After a somewhat protracted struggle, the men-at-arms, seeing famine staring them in the face, recognised the necessity of yielding, and agreed, not only to surrender Norwich, but to leave England in case of their lives being spared. Almost every Breton who had come to England with the Conqueror was involved in the ruin of Ralph de Gael, and departed from the English shores. "Glory be to God in the highest!" Lanfranc wrote joyfully to King William, "your kingdom is freed from the filthy Bretons."

On returning to England, William, at Christmas, held a great council of barons, and dealt with the rebel chiefs. Both were condemned to lose their estates. De Gael, being absent, could not, of course, be punished in person; but Fitzosborne, who appeared before the assembly, was sentenced to perpetual imprisonment.

When matters had reached this stage, a son of Sweyn, King of Denmark, unaware of the ruin of those who had craved assistance, approached the eastern coast. But the Danes made no attempt to land. On learning what had happened they turned their helms towards Flanders, and left Fitzosborne to his fate.

But even captivity and chains could not break the strong spirit nor humble the haughty pride of Fitzosborne. Even in his dungeon he found a way of braving and insulting the king whom he had attempted to dethrone. One day, during Easter, the Conqueror, according to a Norman custom, sent him a magnificent suit of precious stuff, as if he had been at liberty. Fitzosborne received the vestments with a smile, examined the coat and mantle of silk, and handled the jacket, trimmed with foreign furs, as if highly pleased. Having done so, however, Roger ordered a fire to be kindled, and committed coat, mantle, and jacket to the flames.

"Thus," said he, "does the son of William Fitzosborne treat the gifts of the bastard to whom his father gave a crown."

"By the splendour of God!" exclaimed the Conqueror, boiling with anger, when informed of this scene, "the man who has thus insulted me shall never leave his prison alive."
