Once arrived at Duiveland, they could more easily cross the intervening creek to Schouwen, which was not so deep and only half as wide, so that a force thus, sent through these dangerous shallows, might take possession of Duiveland and lay siege to Zierickzee, in the very teeth of the Zealand fleet, which would be unable to sail near enough to intercept their passage.
The Commander determined that the enterprise should be attempted.

It was not a novelty, because Mondragon, as we have seen, had already most brilliantly conducted a very similar expedition.

The present was, however, a much more daring scheme.

The other exploit, although sufficiently hazardous, and entirely, successful, had been a victory gained over the sea alone.

It had been a surprise, and had been effected without any opposition from human enemies.
