outwitting the great stadholder. On the 14th
September he made a retrograde movement towards the Rhine, leaving two
thousand five hundred men in Lingen. Maurice, giving profound thanks to
God for his enemy's infatuation, passed by Lingen, and having now, with
his cousin's reinforcements, a force of nine thousand foot and three
thousand horse, threw himself into Coeworden, strengthened and garrisoned
that vital fortress which Spinola would perhaps have taken as easily as
he had done Lingen, made all the neighbouring positions secure, and then
fell back towards Wesel on the Rhine, in order to watch his antagonist.
Spinola had established his headquarters at Ruhrort, a place where the
river Ruhr empties into the Rhine. He had yielded to the remonstrances of
the Archbishop of Cologne, to whom Kaiserwerth belonged, and had
abandoned the forts which Bucquoy, under his directions, had constructed
at that place.

The two armies now gazed at each other, at a respectful distance, for a
fortnight longer, neither commander apparently having any very definite
purpose. At last, Maurice having well reconnoitred his enemy, perceived a
weak point in his extended lines. A considerable force of Italian
cavalry, with some infantry, was stationed at the village of Mulheim, on
the Ruhr, and apparently out of convenient supporting distance from
Spinola's main army. The stadholder determined to deliver a sudden blow
upon this tender spot, break through the lines, and bring on a general
action by surprise. Assembling his well-seasoned and veteran troopers in
force, he divided them into two formidable bands, one under the charge of
his young brother Frederic Henry, the other under that most brilliant of
cavalry officers, Marcellus Bax, hero of Turnhout and many another
well-fought field.

The river Ruhr was a wide but desultory stream, easily fordable in many
places. On the opposite bank to Mulheim was the Castle of Brock, and some
hills of considerable elevation. Bax was ordered to cross the river and
seize the castle and the heights, Count Henry to attack the enemy's camp
in front, while Maurice himself, following rapidly with the advance of
infantry and wagons, was to sustain the assault.

Marcellus Bax, rapid and dashing as usual, crossed the Ruhr, captured
Broek Castle with ease, and stood ready to prevent the retreat of the
Spaniards. Taken by surprise in front, they would naturally seek refuge
on the other side of the river. That stream
