This made Wade the first whiteman to be a slained victim by the natives of Sarawak. The person who shot Wade with a rifle was later wounded by Mr. Simpson, an officer of the Phlegethon. With this settled, Brooke was then determined to pacify the Iban Dayaks of Skrang and led a strong troop to attack Rentap. On 19 August at Karangan Peris in the Skrang area, Rentap first fought against Brooke's forces. He ambushed the advance trackers of Brooke's reconnoitering troop with a formidable array of war boats and thousands of men on either bank of the river, placed to effectively use spears and blowpipes. With boats and bamboo rafts blocking their retreat, the troop's whiteman leader Mr Stewart, a Malay chief Datuk Patinggi Ali and 30 of his men were killed, and 56 others wounded. This was the first time the Brooke officers saw how devastating the fighting and war by the Iban. On 26 August, a Skrang chief arrived, deputed by the other chiefs of Skrang to assure Captain Keppel of their submission and desire for peace. In 1849, the Iban of Saribas and Skrang combined forces to attack those living near the Batang Rajang river mouth. Brooke quickly engaged British navy to surprise them upon their return. When the Iban troop reached the Maru sandbar, they were bombarded by cannon fires. Sensing danger, some of the Saribas boats stopped at the sandbar and disembarked to escape overland to Saribas with two main boats made daring attacks on the schonner but was deflected, thus escaping into the Saribas river. Brooke force chased after them upriver. At the Battle of Nanga Peka, the Paku Iban and Malay troop enticed Brooke force into a fight after which the Brooke force suffered casualties including 3 sons of their Iban chief, Jugah of Lundu. After this defeat, Brooke force returned to Kuching and sent a captive home to bring Brooke's message requesting the Iban to surrender at Kuching at once to avoid further attack. Meanwhile, the Skrang boats tried to escape by paddling to the Batang Lupar river mouth where they were attacked by British navy ship waiting for their coming. In 1850, after Linggir's defeat at the Battle of Betting Maru, Brooke had a fort built at the junction of the Batang Skrang and the Batang Lupar rivers.
