The king was so indignant at this defeat, that he incited the Norman nobles to stir up an insurrection, hoping, no doubt, to punish the boy by depriving him of his title, altogether.
Once when William was out hunting, he passed the night at a remote castle without military escort. His cousin, Guy of Burgundy, hearing of it, laid a plot to kill him, but this was prevented by the Court fool, who accidentally found it out and travelled all night, at full speed, to warn the Duke of his danger. He managed to get into the castle at four o'clock in the morning, and knocked violently on William's chamber door with the handle of his whip, shouting: "get up! get up, my lord!" William obeyed the summons, and mounting his swiftest horse, half dressed, rode with fiery speed for many hours before he was beyond danger. Even while making his escape, he might have been caught, for his horse was almost exhausted when he had the good fortune to meet a gentleman who supplied him with another.
Later, the young duke had a chance to turn the tables on his cousin, Guy, whom he captured in battle. But remembering that they had been friends in early childhood, William forgave the attempt his cousin had made on his life, and released him.
The King of France was just planning another attack on William's dominions when the young man married, and then Matilda's father became such a powerful ally that the king hesitated. Soon after he died. Relieved of this anxiety, the duke thought he might settle down and enjoy the society of his young wife; but, the Archbishop of Rouen, who had reasons of his own for trying to prevent the marriage, pronounced it unlawful, and the young couple were so distressed that they appealed to the Pope. He decided that if each would build and endow an Abbey, as well as a hospital for the blind, he would grant them dispensation. This was not difficult, so Matilda founded the Holy Trinity for Nuns, and William founded the Monastery of St. Stephen.
Then William set to work to erect a palace for his own dwelling very near the Monastery. Matilda had a great taste for architecture and took pleasure in superintending these buildings. The great hall of the palace was one of the finest apartments in all Europe and the edifice itself was superb.
This royal couple did everything to render their subjects happy and contented, and provided work for them by building ships and harbors, which promoted trade also.
Though we know that Matilda did not love her husband before marriage, she became a devoted wife afterwards, and William showed his entire confidence in her by leaving her to govern his country when he went over to England to obtain a promise from Edward the Confessor that he would adopt him as successor to the throne.
