A week had elapsed since the great dyke had been pierced, and the flotilla now lay motionless--in shallow water, having accomplished less than two miles. The wind, too, was easterly, causing the sea rather to sink than to rise. Everything wore a gloomy aspect, when, fortunately, on the 18th, the wind shifted to the north-west, and for three days blew a gale. The waters rose rapidly, and before the second day was closed the armada was afloat again. Some fugitives from Zoetermeer village now arrived, and informed the Admiral that, by making a detour to the right, he could completely circumvent the bridge and the mere. They guided him, accordingly, to a comparatively low dyke, which led between the villages of Zoetermeer and Benthuyzen: A strong force of Spaniards was stationed in each place, but, seized with a panic, instead of sallying to defend the barrier, they fled inwardly towards Leyden, and halted at the village of North Aa. It was natural that they should be amazed. Nothing is more appalling to the imagination than the rising ocean tide, when man feels himself within its power; and here were the waters, hourly deepening and closing around them, devouring 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.
