although extremely hazardous, for
the enemy to bridge that river, and by so doing ultimately to reduce the
place. But the ocean could not be bridged; and it was quite possible to
convert Antwerp, for a season, into an ocean-port. Standing alone upon an
island, with the sea flowing around it, and with full and free marine
communication with Zeeland and Holland, it might safely bid defiance to
the land-forces, even of so great a commander as Parma. To the
furtherance of this great measure of defence, it was necessary to destroy
certain bulwarks, the chief of (10th June, 1584) which was called the
Blaw-garen Dyke; and Sainte Aldegonde was therefore requested to return
to the city, in order to cause this task to be executed without delay.

Nothing could be more judicious than this advice. The low lands along the
Scheldt were protected against marine encroachments, and the river itself
was confined to its bed, by a magnificent system of dykes, which extended
along its edge towards the ocean, in parallel lines. Other barriers of a
similar nature ran in oblique directions, through the wide open pasture
lands, which they maintained in green fertility, against the
ever-threatening sea. The Blaw-garen, to which the prince mainly alluded,
was connected with the great dyke upon the right bank of the Scheldt.
Between this and the city, another bulwark called the Kowenstyn Dyke,
crossed the country at right angles to the river, and joined the other
two at a point, not very far from Lillo, where the States had a strong
fortress.

The country in this neighbourhood was low, spongy, full of creeks, small
meres, and the old bed of the Scheldt. Orange, therefore, made it very
clear, that by piercing the great dyke just described, such a vast body
of water would be made to pour over the land as to submerge the Kowenstyn
also, the only other obstacle in the passage of fleets from Zeeland to
Antwerp. The city would then be connected with the sea and its islands,
by so vast an expanse of navigable water, that any attempt on Parma's
part to cut off supplies and succour would be hopeless. Antwerp would
laugh the idea of famine to scorn; and although this immunity would be
purchased by the sacrifice of a large amount of agricultural territory
the price so paid was but a slender one, when the existence of the
capital, and with it perhaps of the whole confederacy was at stake.

Sainte Aldegonde and Martini suggested, that, as there would be some
