A private and most audacious attempt to secure the person: of Alva and
the possession of Brussels had failed. He was soon, however, called upon
to employ all his energies against the open warfare which was now
commenced.

According to the plan of the Prince, the provinces were to be attacked
simultaneously, in three places, by his lieutenants, while he himself was
waiting in the neighborhood of Cleves, ready for a fourth assault. An
army of Huguenots and refugees was to enter Artois upon the frontier of
France; a second, under Hoogstraaten, was to operate between the Rhine
and the Meuse; while Louis of Nassau was to raise the standard of revolt
in Friesland.

The two first adventures were destined to be signally unsuccessful. A
force under Seigneur de Cocqueville, latest of all, took the field
towards the end of June. It entered the bailiwick of Hesdin in Artois,
was immediately driven across the frontier by the Count de Roeulx, and
cut to pieces at St. Valery by Marechal de Cossis, governor of Picardy.
This action was upon the 18th July. Of the 2500 men who composed the
expedition, scarce 300 escaped. The few Netherlanders who were taken
prisoners were given to the Spanish government, and, of course, hanged.

The force under the Seigneur de Villars was earlier under arms, and the
sooner defeated. This luckless gentleman, who had replaced the Count of
Hoogstraaten, crossed the frontier of Juliers; in the neighborhood of
Maestricht, by the 20th April. His force, infantry and cavalry, amounted
to nearly three thousand men. The object of the enterprise was to, raise
the country; and, if possible, to obtain a foothold by securing an
important city. Roermonde was the first point of attack, but the
attempts, both by stratagem and by force, to secure the town, were
fruitless. The citizens were not ripe for revolt, and refused the army
admittance. While the invaders were, therefore, endeavoring to fire the
gates, they were driven off by the approach of a Spanish force.

The Duke, so soon as the invasion was known to him, had acted with great
promptness. Don Sancho de Lodrono and Don Sancho de Avila, with five
vanderas of Spanish infantry, three companies of cavalry, and about three
hundred pikemen under Count Eberstein, a force amounting in all to about
1600 picked troops, had been at once despatched against Villars. The
rebel chieftain, abandoning his attempt upon Roermonde, advanced towards
Erkelens. Upon the 25th April
