defeated by Badruddin. Hashim managed to establish a rightful position in Brunei Town to become the next Sultan after successfully defeating the piratical forces led by Yusof who fled to Kimanis in northern Borneo where he was executed. Yusof was the favourite noble to the Sultan and with Hashim's victory, this upset the chances of the son of Sultan Omar Ali Saifuddin II to become the next leader. Mahkota, after his capture in Sarawak in 1844 became the Sultan's adviser in the absence of Yusof who had been executed.

The British destroyed the town forts and invited the population to return with no harm to be done to them while the Sultan remained hiding in the jungle. Another expedition was sent to the interior but also failed to find the Sultan. Brooke remained in Brunei with Captain Rodney Mundy and HMS Iris along with Phlegethon and HMS Hazard while the main expedition continued their mission to suppress piracy in northern Borneo. Upon finding that Haji Saman was
