The fortunate or the prudent had not yet succeeded in entirely plundering their companions, when the distant booming of cannon was heard from the river. Instantly, accoutred as they were in their holiday and fantastic costumes, the soldiers, no longer mutinous, were summoned from banquet and gaming-table, and were ordered forth upon the dykes. The patriot Admiral Boisot, who had so recently defeated the fleet of Bergen, under the eyes of the Grand Commander, had unexpectedly sailed up the Scheld, determined to destroy the, fleet of Antwerp, which upon that occasion had escaped. Between, the forts of Lillo and Callao, he met with twenty-two vessels under the command of Vice-Admiral Haemstede. After a short and sharp action, he was completely victorious. Fourteen of the enemy's ships were burned or sunk, with all their crews, and Admiral Haemstede was taken prisoner. The soldiers opened a warm fire of musketry upon Boisot from the dyke, to which he responded with his cannon. The distance of the combatants, however, made the action unimportant; and the patriots retired down the river, after achieving a complete victory. The Grand Commander was farther than ever from obtaining that foothold on the sea, which as he had informed his sovereign, was the only means by which the Netherlands could be reduced. 1574 [CHAPTER II.] First siege of Leyden--Commencement of the second--Description of the city--Preparations for defence--Letters of Orange--Act of amnesty issued by Requesens--Its conditions--Its reception by the Hollanders--Correspondence of the Glippers--Sorties and fierce combats beneath the walls of Leyden--Position of the Prince--His project of relief Magnanimity of the people--Breaking of the dykes-- Emotions in the city and the besieging camp--Letter of the Estates of Holland--Dangerous illness of the Prince--The "wild Zealanders"-- Admiral Boisot commences his voyage--Sanguinary combat on the Land-- Scheiding--Occupation of that dyke and of the Green Way--Pauses and Progress of the flotilla--The Prince visits the fleet--Horrible sufferings in the city--Speech of Van der Werf--Heroism of the inhabitants--The Admiral's letters--The storm--Advance of Boisot-- Lammen fortress----An anxious night--Midnight retreat of the Spaniards--The Admiral enters the city--Thanksgiving in the great church The Prince in Leyden--Parting words of Valdez--Mutiny--Leyden University founded--The charter--Inauguration ceremonies.
