Negotiations continued. The burgomasters--the party representing wealth and commerce--favored submission; they shrank from the destruction of their property and trade. New advances were made; but while the envoys were still in the camp of Louis, the populace and the Orange party rose, and with them the spirit of resistance. On the 25th of June Amsterdam opened the dykes, and her example was followed by the other cities of Holland; immense loss was entailed, but the flooded country and the cities contained therein, standing like islands amid the waters, were safe from attack by land forces until freezing weather. The revolution continued. William of Orange, afterward William III. of England, was on the 8th of July made stadtholder, and head of the army and navy; and the two De Witts, the heads of the republican party, were murdered by a mob a few weeks later. The resistance born of popular enthusiasm and pride of country was strengthened by the excessive demands of Louis XIV. It was plain that the Provinces must conquer or be destroyed. Meanwhile the other States of Europe were waking up to the danger, and the Emperor of Germany, the Elector of Brandenburg, and the King of Spain declared for Holland; while Sweden, though nominally in alliance with France, was unwilling to see the destruction of the Provinces, because that would be to the advantage of England's sea power. Nevertheless the next year, 1673, opened with promise for France, and the English king was prepared to fulfil his part of the compact on the seas; but the Dutch, under the firm leadership of William of Orange, and with their hold on the sea unshaken, now refused to accept conditions of peace which had been offered by themselves the year before. Three naval battles were fought in 1673, all near the coast of the United Provinces; the first two, June 7 and June 14, off Schoneveldt, from which place they have taken their name; the third, known as the battle of the Texel, August 21. In all three Ruyter attacked, choosing his own time, and retiring when it suited him to the protection of his own shores. For the allies to carry out their objects and make any diversion upon the seaboard, or on the other hand to cripple the sea resources of the hard-pressed Provinces, it was necessary first to deal successfully with Ruyter's fleet. The great admiral and his government both felt this, and took the resolution that "the fleet should be posted in the passage of Schoneveldt, or a little farther south toward Ostend, to observe the enemy, and if attacked, or seeing the enemy's fleet disposed to make a descent upon the shores of the United Provinces, should resist vigorously, by opposing his designs and destroying his ships."[51] From this position, with good lookouts, any movement of the allies would be known.
