evouring the earth beneath their feet, while on the
waves rode a flotilla, manned by a determined race; whose courage and
ferocity were known throughout the world. The Spanish soldiers, brave as
they were on land, were not sailors, and in the naval contests which had
taken place between them and the Hollanders had been almost invariably
defeated. It was not surprising, in these amphibious skirmishes, where
discipline was of little avail, and habitual audacity faltered at the
vague dangers which encompassed them, that the foreign troops should lose
their presence of mind.

Three barriers, one within the other, had now been passed, and the
flotilla, advancing with the advancing waves, and driving the enemy
steadily before it, was drawing nearer to the beleaguered city. As one
circle after another was passed, the besieging army found itself
compressed within a constantly contracting field. The "Ark of Delft," an
enormous vessel, with shot-proof bulwarks, and moved by paddle-wheels
turned by a crank, now arrived at Zoetermeer, and was soon followed by
the whole fleet. After a brief delay, sufficient to allow the few
remaining villagers to escape, both Zoetermeer and Benthuyzen, with the
fortifications, were set on fire, and abandoned to their fate. The blaze
lighted up the desolate and watery waste around, and was seen at Leyden,
where it was hailed as the beacon of hope. Without further impediment,
the armada proceeded to North Aa; the enemy retreating from this position
also, and flying to Zoeterwoude, a strongly fortified village but a mile
and three quarters from the city walls. It was now swarming with troops,
for the bulk of the besieging army had gradually been driven into a
narrow circle of forts, within the immediate neighbourhood of Leyden.
Besides Zoeterwoude, the two posts where they were principally
established were Lammen and Leyderdorp, each within three hundred rods of
the town. At Leyderdorp were the head-quarters of Valdez; Colonel Borgia
commanded in the very strong fortress of Lammen.

The fleet was, however, delayed at North Aa by another barrier, called
the "Kirk-way." The waters, too, spreading once more over a wider space,
and diminishing under an east wind, which had again arisen, no longer
permitted their progress, so that very soon the whole armada was stranded
anew. The waters fell to the depth of nine inches; while the vessels
required eighteen and twenty. Day after day the fleet lay motionless
