Though the Spanish had a settlement on the western end of the island they were unable to keep the Lanun pirates in check, and on occasions were severely handled by them, as were also the Dutch.
With these pirates were associated the Bajaus or sea-gipsies, a roving people, who lived entirely in their prahus, with their women and children.
The vessels employed by Lanuns on marauding expeditions were sometimes of 60 tons burden, built very sharp in the prow and wide in beam, and over 90 feet in length. A double tier of oars was worked by slaves to the number of 100, and the fighting men would be from 30 to 40; the prahus of the smallest size carried from 50 to 80 in all. The bows of the vessels were solidly built, and fortified with hard wooden baulks capable of resisting a 6-pounder shot; often they were shod with iron. Here a narrow embrasure admitted a gun for a 6 to a 24-pound shot. In addition to this, the armaments consisted of several guns, usually of brass, of smaller calibre. Sometimes the piratical fleets comprised as many as 200 prahus, though the Lanuns usually cruised in small fleets of 20 to 30 sail. They would descend on a coast and attack any village, sack and burn it, kill the defenders, carry away men, women, and children as slaves, slaughter the cattle, and ravage the plantations. A cargo of slaves captured on the east coast of Borneo would be sold on the west coast, and those taken in the south would find a ready market in the north, in Sulu110 and the Lanun country. Their cruising grounds were extensive – around the coasts of the Philippine islands, Borneo, and Celebes to Sumatra, Java, and the Malay peninsula, through the Moluccas to New Guinea, and even up the Bay of Bengal as far as Rangoon. In 1834, a fleet of these Lanuns swept round the coast of a small island in the Straits of Rhio, opposite Singapore, and killed or carried away all the inhabitants.111 In addition to their original home in the bay of Lanun, they had settlements in Marudu Bay in the north of Borneo, and towns along the west coast almost as far south as Ambong, and on the east coast to Tungku, and on to Koti. In Marudu their chief was Sherip Usman, who was married to a sister of the Sultan Muda of Sulu, and who was in league with Pangiran Usup, uncle to the Sultan of Bruni, and his principal adviser. Usman supplied the pirates with powder, shot, and guns, and they, on returning from a piratical expedition, paid him at the rate of four captives for every 100 rupees worth of goods with which he had furnished them. Such captives as had been taken in the vicinity of Bruni he would sell to Pangiran Usup for 100 rupees each, who would then demand of their friends and relations Rs. 200 for each. "Thus this vile Sherip, not reckoning the enormous price he charged for his goods in the first instance, gained 500 per cent for every slave, and the Pangiran Usup cleared 100 per cent by the flesh of his own countrymen."
In 1844, Ambong was a flourishing town occupied by an industrious and peaceable people, subjects of the Sultan of Bruni. In 1846, Captain Rodney Mundy, R.N., visited it, and the town was represented by a heap of ruins alone; the inhabitants had been slaughtered, or enslaved to be passed on to Usup, that he might make what he could out of them, by holding them to ransom by their relatives.
The Balenini were hand in glove with the Lanuns, and often associated with them in their expeditions. They issued from a group of islands in the Sulu sea, and acted in complicity with the Sultan of Sulu, whose country was the great nucleus of piracy. They equipped annually considerable fleets to prey upon the commerce with Singapore and the Straits; they also attacked villages, and carried off alike crews of vessels and villagers to slavery, to be crowded for months in the bottom of the pirate vessels, suffering indescribable miseries. Their cruising grounds were also very extensive; the whole circuit of Borneo was exposed to their attacks, except only the Lanun settlements, for hawks do not peck out hawk's een. When pursued and liable to be overtaken, they cut the throats of their captives and threw them overboard, men, women, and children alike. Up to 1848, the principal Balenini strongholds were in Balenini, Tongkil, and Basilan islands, but they were then driven out of the two former islands by the Spaniards, and they established themselves on other islands in the Sulu Archipelago; and Tawi Tawi island, which had always been one of their strongholds, then became their principal one.
Trade with Borneo and the Sulu Archipelago was rendered almost impossible, or at least a very dangerous pursuit, and even merchantmen using the Palawan passage to China, which takes them close along the coast of Borneo, often fell a prey to these pirates.
Earl, writing a year or two before the advent of the late Rajah to Sarawak, remarks in connection with Borneo, that it ought to be considered but "an act of justice to the natives of the Indian Archipelago, whom we have enticed to visit our settlement of Singapore, that some exertion should be made towards the suppression of piracy." He blames the unaccountable indifference and neglect which the British Government had hitherto displayed, and expresses his sympathy for the natives. He considered it his duty to point the way – it was left to the late Rajah to lead in it.
The Natuna, the Anamba, and the Tambilan islands, which stretch across the entrance of the China sea between Borneo and the Malay peninsula, were common lurking haunts of the pirates. Amongst these islands they could find water and shelter; could careen, clean, and repair their prahus; and they were right in the track of vessels bound to Singapore, or northward to the Philippines or China. To replenish their stores and to obtain arms and ammunition they would sail to Singapore in innocent-looking captured prahus, where they found a ready market for their booty amongst the Chinese. Muskets of English make and powder from English factories were found in captured prahus and strongholds. At Patusan a number of barrels of fine gunpowder from Dartford were discovered exactly as these had left the factory in England.
Against these the Rajah was powerless to take the offensive. They had to be left to be reduced or cowed by the spasmodic efforts of British men-of-war. What he urged, though ineffectually, was that a man-of-war should patrol the coast and curb the ruffians. What was actually done, but not until later, was to attack and burn a stronghold or two, and then retire. The pirates fled into the jungle, but returned when the British were gone, rebuilt their houses, and supplied themselves with fresh vessels.
Near at hand were the Saribas and Sekrang Sea-Dayaks occupying the basins of rivers of these names, the Sekrang being an affluent of the Batang Lupar.
In each of these rivers was a large Malay community of some 1000 fighting men who lived by piracy, and who trained the numerous Dayaks, by whom they were surrounded, to the same lawless life that they led themselves, and guided them on their predatory excursions. Here again both Dayaks and Malays were under the influence of Sherips, Mular, his brother Sahap, and others. In course of time these Dayaks became expert seamen, and, accompanied by the Malays, yearly issued forth with fleets composed of a hundred or more bangkongs,112 sweeping the seas and carrying desolation along the shores of Borneo over a distance of 800 miles.
The Sea-Dayaks soon became aware of their power; and accordingly, both in their internal government and on their piratical expeditions, their chiefs attained an authority superior to that of the Malay chiefs, their titular rulers.
In May, 1843, H.M.S. Dido started on her eventful cruise to Borneo, having the Rajah on board. After passing Sambas, Captain Keppel dispatched the pinnace and two cutters under the first lieutenant, with whom went the Rajah, to cruise along the coast. Lanun pirates were seen, but, easily outsailing the flotilla, escaped. Off Sirhasan, the largest of the group of the Natuna islands, whither the boats had been directed to go, six prahus, some belonging to the Rajah Muda of Rhio (an island close to Singapore, belonging to the Dutch, and under a Dutch Resident), and some to the islanders, mistaking the Dido's boats for those of a shipwrecked
