When Libau RENTAP realised that it was useless for him to defend the fortress of Bukit Sadok any longer, he commanded his war men to leave it from the opposite side of the mountain. Now the attacking party of Tuan Muda Charles Brooke under cover of the musket shot, rushed over the neck of the rock and entered the fortress through the holes made by the shots from “Bujang Sadok”.
They found that Libau RENTAP and his war men had escaped except for the dead and dying. Inside the fortress they also found the arms captured by Libau RENTAP when he fought against Alan Lee and William Brereton at Lintang Batang stockade in 1853. A large quantity of gun powder and the famous one armed iron cannon named the “Bujang Timpang Berang”. That afternoon the Sarawak Government Forces attacking party burnt down Libau RENTAP fortress at Bukit Sadok. A guns was fired and in ten minutes a tongue of flame shot up into the sky with thick black smokes. At dusk the summit of Bukit Sadok was seen burning for miles and miles away. It marked the end of Libau RENTAP’s power over the White Rajah’s and his long career as a great Dayak Iban war leader where he got the title of Raja Ulu, but he won’t surrender his life to the White Rajah’s.
Libau RENTAP and his war men did not surrender but retreated to Bukit Lanjak Entimau at the headwaters of Batang Skrang, Lemanak and Engkari. He then moved down to the Ulu Entabai the branch of Kanowit and Julau and made another fortress at Bukit Setulak. At his old ages he moved to Karangan Panggil in Ulu Wak, Pakan and died at old ages in the year 1870. He was not buried, but his remains was kept according to the symbol of the Dayak Iban warrior, but honourably laid down to rest in peace in a mortuary known by the Dayak Iban as “Lumbong”.
His tomb, the “Lumbong” is still intact today located at the summit of Bukit Sibau at the headwaters of Budu/Kabo River of Saratok and Wak River of Pakan. His remains was before kept in a large ceramic jar but it was later placed inside a coffin after the reburial of his remains was done in October, 1989 which was done by the Sarawak State Government in the Dayak Iban traditional heroes burial ceremony named Gawai Ngelombong.
