By the alliance with the kings of France, the Norman dukes had been greatly helped to gain their present eminence, and to the Norman dukes the French kings, in their turn, owed their stability upon their own thrones; they had fought for each other and stood by each other again and again. Now, there was a rift between them that grew wider and wider—a rift that came from jealousy and fear of the Normans' wealth and enormous growth in strength. They were masters of the Breton country, and had close ties of relationship, moreover, with not only Brittany, but with Flanders and the smaller county of Ponthieu, which lay between them and the Flemings. Normandy stretched her huge bulk and strength between France and the sea; she commanded the French rivers, the French borders; she was too much to be feared; if ever her pride were to be brought down, and the old vassalage insisted upon, it could not be too soon. Henry forgot all that he owed to the Normans' protection, and provoked them by incessant hostilities—secret and open treacheries,—and the fox waged war upon the lion, until a spirit of enmity was roused that hardly slept again for five hundred years. There were other princes ready enough to satisfy their fear and jealousy. The lands of the conspirators stretched from Burgundy to the Pyrenees. Burgundy, Blois, Ponthieu, Aquitaine, and Poictiers all joined in the chase for this William the Bastard, the chief of the hated pirates. All the old gibes and [Pg247] taunts, and contemptuous animosity were revived; now was the time to put an end to the Norman's outrageous greed of power and insolence of possession, and the great allied army divided itself in two parts, and marched away to Normandy. King Henry's brother, Odo, turned his forces toward Rouen, and the king himself took a more southerly direction, by the way of Lisieux to the sea. They meant, at any rate, to pen the duke into his old Danish region of the Côtentin and Bessin districts; all his eastern lands, the grant from Charles the Simple, with the rest, were to be seized upon and taken back by their original owners.
