Dutch capture of Bonjol ends the Padri War

Background. The Padri War began in 1803 as a conflict between Padri Muslim clerics and Adat traditionalists in Minangkabau. Traditionalists appealed to the Dutch for help against the Padris. The Dutch initially struggled due to resources being stretched by the Diponegoro resistance in Java, but eventually intensified their military efforts in West Sumatra.

Siege of Bonjol. Tuanku Imam Bonjol continued the struggle from his fortress in Bonjol after escaping capture in 1832. The Dutch attack on Bonjol had failed by September 1833, as reported by van den Bosch before the Governor-General was replaced. A renewed offensive began in mid-August 1835 after Bugis reinforcements arrived, but Dutch troops still failed to control Mount Tajadi, and a large-scale final attack was launched in December 1836.

Final Assault. In early 1837, Major General Cochius led a massive attack on Fort Bonjol. Dutch troops surrounded Bonjol from all directions for six months. Additional troops arrived in July 1837. On 15 August 1837, Tajadi Hill fell, and Fort Bonjol was completely conquered on 16 August 1837.
