Sungai Ujong

His struggle against the British began in March 1872 when Datuk Kelana Syed Abdul Rahman, who governed Sungai Ujong (modern-day Seremban) allowed the British to open a tin mine and set up their operations within his domain. With the help of British soldiers, he defeated his enemy Datuk Bandar Tunggal and burned Rahang.

As the appointment of a foreigner, Resident P.J. Murray, into Datuk Kelana's court was seen by other local officials as a telltale sign of a British invasion, the officials crowned Tuanku Antah as the Yamtuan of Seri Menanti, who did not recognise Datuk Kelana's authority.

Datuk Kelana claimed Terachi as part of his territory in 1875, which led to Tuanku Antah's ire. He dismissed the local government there that supported Datuk Kelana. Resident Murray interpreted this as a breach against Datuk Kelana's administration, so he went to Terachi with 20 soldiers led by Lt. Hinxman, and an interpreter and doctor from Australia, Dominic Daly, to investigate, but they did not find any sign of disorder there. Murray returned to Sungai Ujong, but Daly travelled from Terachi to Kuala Pilah to measure their distances. Daly was turned away when his party stumbled unto 200 men who threatened them to leave, and requested Murray to help him.^[1]

Battle of Bukit Putus

Tuanku Antah mobilised 4000 soldiers in preparation for the oncoming British invasion, and was helped by several others: Datuk Siamang Gagap, the Tunku Besar of Tampin, and the people of Rembau, Jelebu, and Johol. His army marched into Bukit Putus and Paroi, where he warned Murray not to interfere with his sovereignty by trespassing into Terachi. The British Resident then requested help from the Straits Settlements, who sent 20 soldiers led by Lt. Peyton from Malacca, while Lt. Hinxman and his troops immediately dug trenches and fortified their compound, due to uprisings. Lt. Hinxman also brought another army with him, consisting of 30 troops, 30 policemen, and 6 Arabs, to attack Tuanku Antah at Paroi, but they were outnumbered by the locals, who surrounded and defeated them, while Tuanku Antah's forces occupied a house along the banks of the Linggi River as their base of operations.

On 5 December 1875, the British used Datuk Kelana's cannons to fight against Tuanku Antah. After a one-hour-long shootout, Lts. Hinxman and Peyton advanced through a swamp to destroy Tuanku Antah's fort, but they were not able to find him, and Tunku Laksamana took his place to govern Seri Menanti.

Reinforced by 350 soldiers led by Governor Anson from Penang, the British bombarded Tuanku Antah's fortress. Tuanku Antah was forced to retreat, and the British retook Paroi. With the arrival of the battleship HMS Thistle to Sungai Ujong, still more reinforcements arrived under Lt. Col. Clay, who led his group of 280 soldiers to retake Bukit Sungai Ujong. He later led his troops through Langkap into Bukit Putus, where his forces defeated more of Tuanku Antah's soldiers, and advanced on to Seri Menanti. Notified of the British approaching to his capital, Tuanku Antah fled with his family to Johor, where they came into the protection of Sultan Abu Bakar.

Sultan Abu Bakar then advised him to make peace with the British. In May 1876, Tuanku Antah arranged a meeting with the four Undangs of Negeri Sembilan between them and William Jervois, the Governor of Singapore. Under a peace treaty between all the belligerents, the British agreed to allow Tuanku Antah to rule Seri Menanti, Johol, Ulu Muar, Jempol, Terachi, Gunung Pasir, and Ineh, and renamed his title Yang di-Pertuan Seri Menanti while the other regions of Negeri Sembilan will continue to be ruled by their respective leaders, and Sungai Ujong remains under British rule.^[1]
