Fourth Larut War occurred in 1873, merely a year after the previous battle. Weeks after the Hai Sans regained Larut, the Ghee Hin, supported by Raja Abdullah, counter-attacked with arms and men from Singapore and China. Ngah Ibrahim's properties in Matang were destroyed. Local Malay residents were also killed and their property, destroyed. Trouble spread to Krian, Pangkor and Dindings. The quarrelling Malay chiefs who had taken sides in the Larut Wars were now alarmed at the disorder created by the Chinese miners and secret societies. The Straits Settlement Penang Chinese seeing their investments destroyed in the Larut Wars sought intervention form British. Over 40,000 Chinese from the Go-Kuan and Si-Kuan were engaged in the fratricidal war involving the Perak royal family. In August 1873, Archibald Edward Harbord Anson, the last Lieutenant-Governor of Penang, sought to bring about a ceasefire between the two parties and convened a meeting at the beginning of the month attended, apart from Anson, by Chung Keng Quee (Hai San), Ho Ghi Sui (Ghee Hin), Foo Tye Sin (pro-Hai San), Ngah Ibrahim (pro-Hai San), Abdullah (pro-Ghee Hin), Tengku Kudin (pro-Abdullah) and a British Naval Captain. The two sides agreed to keep the peace pending British arbitration with Ngah Ibrahim taking responsibility for the Hai San and Abdullah taking responsibility for the Ghee Hin. Abdullah failed so completely in his task in ensuring the Ghee Hin kept the peace that the British were prompted to back Ngah Ibrahim and the Hai San. On 3 September 1873 outgoing Straits Settlements Governor Sir Harry Ord recognised Ngah Ibrahim, through a proclamation, as the independent (i.e. independent of Perak rule) ruler of Larut. On 5 September he temporarily lifted an arms embargo (imposed since February) just long enough for the Hai San in Larut to receive munitions. In the middle of that month a British vessel got into an entanglement with some Ghee Hin junks and this led to British bombardment and capture of Ghee hin stockades at Matang and Kuala Selinsing. Ngah Ibrahim's Penang residence was blown up on 16 September 1873. A week later two things happened - a similar attempt was made on Chung Keng Quee's house and Abdullah and his Ghee Hin cohorts were arrested at sea and brought back to Penang where they were eventually released but forbidden to return to Perak.
