King Henry, on the other side, was very apprehensive of his nephew's greatness, well knowing to what end it was directed; however, he seemed not to regard it, contenting himself to give the Earl employment at home by privately nourishing the discontents of his new subjects, and abetting underhand another pretender: for William had so entirely lost the hearts of his people, by his intolerable avarice and exactions, that the principal towns in Flanders revolted from him, and invited Thierri Earl of Alsace to be their governor. But the King of France generously resolved to appear once more in his defence, and took his third expedition into Flanders for that purpose. He had marched as far as Artois, when he was suddenly recalled to defend his own dominions from the fury of a powerful and provoked invader: for Henry King of England, moved with indignation to see the French King in the midst of a peace so frequently and openly supporting his most dangerous enemy, thought it the best way to divert Louis from kindling a fire against him abroad, by forcing him to extinguish one at home: he therefore entered into the bowels of France, ravaging and laying waste all before him, and quickly grew so formidable, that the French King to purchase a peace was forced to promise never more to assist or favour the Earl of Flanders; however, as it fell out, this article proved to be wholly needless; for the young Earl soon after gave battle to Thierri, and put his whole army to the rout; but pursuing his victory, he received a wound in his wrist, which, by the unskilfulness of a surgeon, cost him his life.[24] [Footnote 24: The lance passed through or under the ball of his thumb into his wrist. The wound gangrening, he died within five days. [D.S.]] This one slight inconsiderable accident did, in all probability, put a stop to very great events; for if that young prince had survived his victory, it is hardly to be doubted but through the justness of his cause, the reputation of his valour, and the assistance of the King of France, he would in a little time have recovered Normandy, and perhaps his father's liberty, which were the two designs he had in agitation; nor could he well have missed the crown of England after the King's death, who was now in his decline, when he had so fair a title, and no competitors in view but a woman and an infant. 1129.
