Had this expedition started but a few days earlier, the mischief that had been done would have been prevented, though that mischief was far less than it would have been had not the pirates been forced to beat a hasty retreat on receiving news that so powerful a force was out against them. They had attacked Matu, but that town was found to be too well prepared to be carried without considerable loss, and, their aim being not glory but to procure heads, captives, and plunder, with the least possible risk to themselves, they retreated in search of easier prey after sustaining a loss of ten killed, but not before they had taken a detached house in which they obtained seven heads and captured four girls. Palo they had plundered, and had there seized three girls;[167] they spared the place as being the main source of their salt supply. Two vessels trading to Singapore were captured, and the crew of one were all killed. Serikei proved too strong for them. A detachment had gone westward, and off Sambas they killed some Chinese fishermen and took their heads. At Sirhasan, one of the Natuna islands, they captured a trading vessel, and on their way back to join the main fleet attacked the Malays living at the mouth of Muaratebas, but were repulsed after a desperate fight. A trading prahu was there seized, the owner and five of the crew being killed. Coming across Abang Husin, a nephew of the Datu Temanggong, they killed him and his boat's crew of six, after a gallant defence.
A couple of days having been spent in destroying the captured bangkongs and securing prisoners, the expedition proceeded up the Saribas river. After some exciting episodes and hard work in cutting their way through innumerable trees, which had been felled across the river to impede their progress, the force reached Paku, which was taken and burnt for the second time. The expedition then proceeded up the Rejang, to punish the Sekrang Dayaks living in the Kanowit. Eighteen villages were destroyed, and the country laid waste for a hundred miles. This done, the Rajah returned to Kuching with the whole force, arriving there on August the 24th. With him came many Serikei people, who wished to escape from the tyranny of Sherip Masahor,[168] an infamous and intriguing half-bred Arab chief, who appears to have but lately settled in the Rejang as the Bruni governor, and who in the near future was to cause the Sarawak Government considerable trouble.
