Tengku Alam and his followers launched the first blow of the war by seizing Jementah town, just outside Segamat, on 25 October 1879. The headman or governor of Jementah reported to the ruler of Johor, Maharaja Abu Bakar, who responded by sending a powerful force led by his cousin, Ungku Ahmad. Ungku Ahmad was a great tactician who contributed to the Johor Government's rapid victory.
