Admiral Boisot and the Prince of Orange had been misinformed as to the lie of the lands, and had assumed that the rupture of the "Land-scheiding" would flood the country inland all the way to Leiden. Instead, the rebel flotilla once again found their path blocked, this time by the Greenway dike, less than a mile inland of the "Land-scheiding", which was still a foot above the water level. Again however the Spaniards had left the dike largely undefended, and the Dutch broke through it without much difficulty. Due to easterly winds driving the water back seawards, and the ever growing surface area of the land that the water covered, the flooding was by this time so shallow that the fleet was all but stranded. The only way that was deep enough for them to proceed was by a canal, leading to a large inland lake called the "Zoetermeer" (freshwater lake). This canal, and the bridge over it, were strongly defended by the Spaniards, and after a brief amphibious struggle, the Admiral gave up the venture. He dispatched a despondent message to the Prince, saying that unless the wind turned, and they could sail around the canal, they were lost.
