Brederode declined to do so and resigned their offices. Orange offered
his resignation, but Margaret was unwilling to accept it and urged him
to discuss the matter first with Egmont and Meghem. The three nobles met
accordingly at Willebroek, April 2. William used his utmost powers of
persuasion in an attempt to convince Egmont that he was courting
destruction. But in vain. He himself was not to be moved from his
decision, and the two friends, who had worked together so long in the
patriot cause, parted, never to meet again. Orange saw that he was no

Orange did not take this extreme step without adequate cause. At the
very time that he left the Netherlands Philip was taking leave of the
Duke of Alva, whom he was despatching at the head of a veteran force to

who had ventured to oppose the arbitrary exercise of the royal
authority. He had for some time been preparing this expedition. He still
kept up the pretence that he was coming in person to enquire into the
alleged grievances, but he never had the slightest intention of quitting
Madrid. Alva sailed from Cartagena (April 27) for Genoa, and proceeded

picked body of some 12,000 men. With these he set out in June for his
long march across the Alps and through Burgundy, Lorraine and Luxemburg.
His progress, jealously watched by the French and Swiss, met with no
opposition save for the difficulties of the route. He entered the
Netherlands on August 8, with his army intact. A number of notables,
