A Spanish officer who had mounted the breach for an instant, and, after being hurled back, almost miraculously escaped with his life, reported that he had seen neither helmet nor harness as he looked down into the city -- only some plain looking people, generally dressed like fishermen. The cannonade was renewed on the following morning, and after 700 shots had been fired and the breaches enlarged, a fresh assault was ordered. But the troops absolutely refused to advance. It seemed to them that the devil, whom they believed the Protestants worshipped, had protected the city, otherwise how could a handful of townsmen and fishermen have defeated the invincible soldiers of Spain, outnumbering them eight fold.

In vain Don Frederick and his generals entreated and stormed. Several of the soldiers were run through the body, but even this did not intimidate the rest into submission, and the assault was in consequence postponed. Already, indeed, there was considerable uneasiness in the Spanish camp. Governor Sonoy had opened many of the dykes, and the ground in the neighbourhood of the camp was already feeling soft and boggy. It needed but that two great dykes should be pierced to spread inundation over the whole country. The carpenter who had soon after the commencement of the siege carried out the despatches had again made his way back. He was the bearer of the copy of a letter sent from the prince to Sonoy, ordering him to protect the dykes and sluices with strong guards, lest the peasants, in order to save their crops, should repair the breaches. He was directed to flood the whole country at all risks rather than to allow Alkmaar to fall. The prince directed the citizens to kindle four great beacon fires as soon as it should prove necessary to resort to extreme measures, and solemnly promised that as soon as the signal was given an inundation should be created which would sweep the whole Spanish army into the sea.
