This doctrine in the History of International Law is known as that of mare clausum, or “closed sea.” The death-blow to this domination was given by the entrance of the Dutch into the Indies, and it is not a mere coincidence that we find the doctrine of closed sea itself scientifically assailed, a few years later, by the great Dutch jurist, Grotius, the founder of the system of international law in his work, De Libero Mare.
The Trading Methods of the Dutch.—The Dutch made no attempts in the Indies to found great colonies for political domination and religious conversion. Commerce was their sole object. Their policy was to form alliances with native rulers, promising to assist them against the rule of the Portuguese or Spaniard in return for exclusive privileges of trade. In this they were more than successful.
In 1602 they obtained permission to establish a factory at Bantam, on the island of Java. This was even then a considerable trading-point. “Chinese, Arabs, Persians, Moors, Turks, Malabars, Peguans, and merchants from all nations were established there,” the principal object of trade being pepper.[2]
The character of the treaty made by the Dutch with the king of Bantam is stated by Raffles. “The Dutch stipulated to assist him against foreign invaders, particularly Spaniards and Portuguese; and the king, on his side, agreed to make over to the Dutch a good and strong fort, a free trade, and security for “their persons and property without payment of any duties or taxes, and to allow no other European nation to trade or reside in his territories.”
Spanish Expedition against the Dutch in the Moluccas.—The Spaniards, however, did not relinquish the field to these new foes without a struggle, and the conflict fills the history of the eighteenth century. When the Dutch expelled the Portuguese from Amboina and Tidor in February, 1605, many of the Portuguese came to the Philippines and enlisted in the Spanish forces. The governor, Don Pedro Bravo de Acuña, filled with wrath at the loss of these important possessions, with great activity organized an expedition for their conquest.
In the previous year there had arrived from Spain eight hundred troops, two hundred of them being native Mexicans. Thus Acuña was able to organize a powerful fleet that mounted seventy-five pieces of artillery and carried over fourteen hundred Spaniards and sixteen hundred Indians.[3] The fleet sailed in January, 1606. Tidor was taken without resistance and the Dutch factory seized, with a great store of money, goods, and weapons. The Spaniards then assailed Ternate; the fort and plaza were bombarded, and then the town was carried by storm.
Thus, at last was accomplished the adventure which for nearly a century had inspired the ambitions of the Spaniards, which had drawn the fleet of Magellan, which had wrecked the expeditions of Loyasa and Villalobos, for which the Spaniards in the Philippines had prepared expedition after expedition, and for which Governor Dasmariñas had sacrificed his life. At last the Moluccas had been taken by the forces of Spain.
Capture of a Dutch Fleet at Mariveles.—So far from disposing of their enemies, however, this action simply brought the Dutch into the Philippines. In 1609, Juan de Silva became governor of the Islands and in the same year arrived the Dutch admiral, Wittert, with a squadron. After an unsuccessful attack on Iloilo, the Dutch fleet anchored off Mariveles, to capture vessels arriving for the Manila trade.
At this place, on the 25th of April, 1610, the Spanish fleet, which had been hastily fitted at Cavite, attacked the Dutch, killing the admiral and taking all the ships but one, two hundred and fifty prisoners, and a large amount of silver and merchandise. These prisoners seem to have been treated with more mercy than the captives of Van Noort’s fleet, who were hung at Cavite. The wounded are said to have been cared for, and the friars from all the religious orders vied with one another to convert these “Protestant pirates” from their heresy.
An Expedition against the Dutch in Java.—Spain made a truce of her European wars with Holland in 1609, but this cessation of hostilities was never recognized in the East. The Dutch and Spanish colonists continued to war upon and pillage each other until late in the century. Encouraged by his victory over Wittert, Silva negotiated with the Portuguese allies in Goa, India, to drive the Dutch from Java. A powerful squadron sailed from Cavite in 1616 for this purpose. It was the largest fleet which up to that date had ever been assembled in the Philippines. The expedition, however, failed to unite with their Portuguese allies, and in April, Silva died at Malacca of malignant fever.
