Yssel formed two sides of a great quadrilateral; and
furnished for the natural fortress, thus enclosed, two vast and admirable
moats. Within lay Good-meadow and Foul-meadow--Bet-uwe and Vel-uwe--one,
the ancient Batavian island which from time immemorial had given its name
to the commonwealth, the other, the once dismal swamp which toil and
intelligence had in the course of centuries transformed into the wealthy
and flowery land of Gueldres.

Beyond, but in immediate proximity, lay the ancient episcopal city and
province of Utrecht, over which lay the road to the adjacent Holland and
Zeeland. The very heart of the republic would be laid bare to the
conqueror's sword if he could once force the passage, and obtain the
control of these two protecting streams. With Utrecht as his base, and
all Brabant and Flanders--obedient provinces--at his back, Spinola might
accomplish more in one season than Alva, Don John, and Alexander Farnese
had compassed in forty years, and destroy at a blow what was still called
the Netherland rebellion. The passage of the rivers once effected, the
two enveloping wings would fold themselves together, and the conquest
would be made.

Thus reasoned the brilliant young general, and his projects, although
far-reaching, did not seem wild. The first steps were, however, the most
important as well as the most difficult, and he had to reckon with a wary
and experienced antagonist. Maurice had at last collected and reviewed at
Arnhem an army of nearly fifteen thousand men, and was now watching
closely from Doesburg and Deventer every movement of the foe.

Having been forced to a defensive campaign, in which he was not likely at
best to gain many additional laurels, he was the more determined to lay
down his own life, and sacrifice every man he could bring into the field,
before Spinola should march into the cherished domains of Utrecht and
Holland. Meantime the rain, which had already exerted so much influence
on the military movements of the year, still maintained the supremacy
over human plans. The Yssel and the Waal, always deep, broad, sluggish,
but dangerous rivers--the Rhine in its old age--were swollen into
enormous proportions, their currents flowing for the time with the vigour
of their far away youth.

Maurice had confided the defence of the Waal to Warner Du Bois, under
whose orders he placed a force of about seven thousand men, and whose
business it was to prevent Bucquoy's passage. His own
