Cause → Event → Consequence
The Topasses, a mixed Portuguese-Timorese community, held significant influence over Timor and came into conflict with the Dutch East India Company (VOC), which sought to expand its control over the island. Tensions escalated to open military confrontation by 1749.
On 9 November 1749, a large Topass army engaged a numerically smaller VOC force on the hillside of Penfui near modern Kupang. During the battle, the Timorese allies of the Topasses abandoned the fight, decisively shifting the outcome. The Topass leader Gaspar da Costa was killed, and the Topass army was defeated.
Following the defeat, both Topass and Portuguese influence on Timor declined significantly. Over time, a formal boundary was drawn between Dutch and Portuguese Timor, a division that eventually became the modern border between West Timor, part of Indonesia, and East Timor, now the independent nation of Timor-Leste.
