The United Provinces were in truth the mainspring of the coalition. Though among the smallest in extent of the countries arrayed against Louis, they were strongest in the character and purpose of their ruler, the Prince of Orange, and in the wealth which, while supporting the armies of the confederates, also kept the poor and greedy German princes faithful to their alliance. Almost alone, by dint of mighty sea power, by commercial and maritime ability, they bore the burden of the war; and though they staggered and complained, they still bore it. As in later centuries England, so at the time we are now speaking of Holland, the great sea power, supported the war against the ambition of France; but her sufferings were great. Her commerce, preyed upon by French privateers, lost heavily; and there was added an immense indirect loss in the transfer of the carrying-trade between foreign countries, which had contributed so much to the prosperity of the Dutch. When the flag of England became neutral, this rich business went to her ships, which crossed the seas the more securely because of the eager desire of Louis to conciliate the English nation. This desire led him also to make very large concessions to English exigencies in the matter of commercial treaties, undoing much of the work of protection upon which Colbert sought to nourish the yet feeble growth of French sea power. These sops, however, only stayed for a moment the passions which were driving England; it was not self-interest, but stronger motives, which impelled her to a break with France.
