Getting home to Normandy, and understanding the King better now, he naturally allied himself with his old friend the Earl of Shrewsbury, who had still thirty castles in that country.

This was exactly what Henry wanted.

He immediately declared that Robert had broken the treaty, and next year invaded Normandy.
He pretended that he came to deliver the Normans, at their own request, from his brother's misrule.

There is reason to fear that his misrule was bad enough; for his beautiful wife had died, leaving him with an infant son, and his court was again so careless, dissipated, and ill-regulated, that it was said he sometimes lay in bed of a day for want of clothes to put on--his attendants having stolen all his dresses.

But he headed his army like a brave prince and a gallant soldier, though he had the misfortune to be taken prisoner by King Henry, with four hundred of his Knights.
