On their arrival, they began active operations. They were repelled on all sides, and after seven days’ ineffectual attempts, they gave up their design. They returned to Manilla, it is said, with a loss of half their number, and without having done any injury to the Sooloos. Not discouraged with this failure, the Spaniards, about two years after, organized a still larger force, which is estimated by some accounts as high as ten thousand men. Although this failed in its attempts on the fort at Soung, the Spaniards obtained possession of Tanjong Matonda, one of the small ports on the island, where they erected a church and fort. Here they established a colony, and appointed a governor. The inhabitants upon this deserted their habitations in the neighbourhood, and fled to the mountains, which, it is said, excited the mountaineers, a host of whom, with their chief, whose name was Sri Kala, determined to rush upon the Spaniards, and annihilate them. Having to contend against disciplined troops, it was not an easy task to succeed. But Sri Kala had a follower, named Sigalo, who offered to lead the host to battle against the Spaniards, and to exterminate them, or to die in the attempt. The chief accepted his offer, and Sigalo, with a chosen few, marched towards the fort, leaving the rest of the mountaineers in readiness to join them at an appointed signal, and rush into the fort en masse.

Sri Kala and Sigalo, in order to lull the watchfulness of the Spaniards, took with them a young woman, of exquisite beauty, named Purmassuri. The lustful Spaniards were thus thrown off their guard, the signal was given, and the host, rushing forward, entered the fort, every Spaniard within which was slain. A few only, who were on the outside, escaped to the vessels, which set sail, and after encountering various mishaps, returned to Manilla

Some time after this the Sultan Bantilan died, and his son Alimud-deen was proclaimed sultan. Dalrymple did not return until 1762, with a part of the appointed cargo; but the vessel in which the larger part had been shipped, failed to arrive, from not being able to find Sooloo, and went to China. Thence she proceeded to Manilla, and afterwards to Sooloo. The captain of the latter vessel gave a new credit to the Sooloos, before they had paid for their first cargo; and on the arrival of Dalrymple the next time, he found that the small-pox had carried off a large number of the inhabitants, from which circumstance all his hopes of profit were frustrated. He then obtained for the use of the East India Company, a grant of the island of Balambangan, which lies off the north end of Borneo, forming one side of the Straits of Balabac, the western entrance to the Sooloo Sea. Here he proposed to establish a trading port, and after having visited Madras, he took possession of this island in 1763.

In October, 1763, the English took Manilla,[46] where the Sultan Amir was found by Dalrymple, who engaged to reinstate him on his throne, if he would cede to the English the north end of Borneo, as well as the south end of Palawan. This he readily promised, and he was, in consequence, carried back to Sooloo, and reinstated; his nephew, Alim-ud-deen, readily giving place to him, and confirming the grant to the East India Company, in which the Ruma Bechara joined.

After various arrangements, the East India Company took possession of Balambangan, in the year 1773, and formed a settlement there with a view of making it an emporium of trade for Eastern commodities. Troops and stores were sent from India, and the population began to increase by settlers, both Chinese and Malays, who arrived in numbers. In the year 1775, the fort, notwithstanding all the treaties and engagements between Dalrymple and the Sultan, was surprised by the Sultan, and many of the garrison put to death. This virtually put an end to the plans of the English, although another attempt was made to re-establish the settlement by Colonel Farquhar, in 1803; but it was thought to be too expensive a post, and was accordingly abandoned in the next year. This act of the Sooloos fairly established their character for perfidy, and ever since that transaction they have been looked upon as treacherous in the highest degree, and, what is singular, have been allowed to carry on their piracies quite unmolested. The taking of Balambangan has been generally imputed to the treacherous disposition and innate love of plunder among the Sooloos, as well as to their fear that it would destroy the trade of Sooloo by injuring all that of the archipelago. But there are strong reasons for believing that this dark deed owed its origin in part to the influence of the Spaniards and Dutch, who looked with much distrust upon the growth of the rival establishment. Such was the jealousy of the Spaniards, that the governor of the Philippines peremptorily required that Balambangan should be evacuated. The Sooloos boast of the deed, and admit that they received assistance from both Samboangan and Ternate, the two nearest Spanish and Dutch ports. These nations had great reasons to fear, the establishment of a power like that of the East India Company, in a spot so favorably situated to secure the trade of the surrounding islands, possessing fine harbours, and in every way adapted to become a great commercial depôt. Had it been held by the East India Company but for a few years, it must have become what Singapore is now.

The original planner of this settlement is said to have been Lord Pigot; but the merit of carrying it forward was undoubtedly due to Dalrymple, whose enterprising mind saw the advantage of the situation, and whose energy was capable of carrying the project successfully forward.

Since the capture of Balambangan, there has been no event in the history of Sooloo that has made any of the reigns of the Sultans memorable, although fifteen have since ascended the throne.

Sooloo has from all the accounts very much changed in its character as well as population since the arrival of the Spaniards, and the establishment of their authority in the Philippines. Before that event, some accounts state that the trade with the Chinese was of great extent, and that from four to five hundred junks arrived annually from Cambojia, with which Sooloo principally traded. At that time the population is said to have equalled in density that of the thickly-settled parts of China.

The government has also undergone a change; for the sultan, who among other Malay races is usually despotic, is here a mere cipher, and the government has become an oligarchy. This change has probably been brought about by the increase of the privileged class of datus, all of whom are entitled to a seat in the Ruma Bechara until about the year 1810, when the great inconvenience of so large a council was felt, and it became impossible to control it without great difficulty and trouble on the part of the sultan. The Ruma Bechara was then reduced until it contained but six of the principal datus, who assumed the power of controlling the state. The Ruma Bechara, however, in consequence of the complaints of many powerful datus, was enlarged; but the more powerful, and those who have the largest numerical force of slaves, still rule over its deliberations. The whole power, within the last thirty years, has been usurped by one or two datus, who now have monopolized the little foreign trade that comes to these islands. The sultan has the right to appoint his successor, and generally names him while living. In default of this, the choice devolves upon the Ruma Bechara, who elect by a majority.

From a more frequent intercourse with Europeans and the discovery of new routes through these seas, the opportunities of committing depredations have become less frequent, and the fear of detection greater. By this latter motive they are more swayed than by any thing else, and if the Sooloos have ever been bold and daring robbers on the high seas, they have very much changed.
