Rentap and his warriors 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 built another fortress at Bukit Stulak. When he retired from fighting, he moved to Karangan Panggil in Ulu Wak, Pakan, and died of old age in the year 1870. He was not buried, but his remains were kept according to the symbol of the Iban-Dayak warrior which was honourably laid down to rest in peace in a mortuary known by the Iban Dayak as Lumbong. Later, his remains were installed inside a jar in a traditional ceremony known as Ngerapoh.
