Leyden (Netherlands War of Independence).
This city was invested May 26, 1574, by 8,000 Walloons and Germans under Valdez, who in the course of a few days had erected 62 batteries round the place. There was no garrison, with the exception of a few "freebooters" and a burgher guard, under Jan van der Does. The Prince of Orange, in order to save the city, determined to open the dykes, and on August 3 the gates at Schiedam and Rotterdam were opened, and the dykes broken along the course of the Yssel. Meanwhile the citizens had come to an end of their bread, but by strenuous efforts the fleet under Admiral Boisot succeeded in throwing relief into the city at the beginning of October. By this time the city was on the verge of starvation, and 8,000 of the inhabitants had perished of pestilence. The Spaniards, however, had been driven from work after work, and on October 3 the last of their redoubts was mastered, and Valdez was forced to raise the siege.
