Cause

After three failed attempts to capture the Kingdom of Kandy, the Portuguese grew alarmed when King Rajasinghe II began negotiating with the Dutch for military assistance. Portuguese Captain General Diogo de Melo de Castro sought to provoke the Sinhalese, seizing an elephant gifted by the king, which escalated tensions and prompted him to march his forces toward Kandy.

Event

On 28 March 1638, the Sinhalese army ambushed the Portuguese force at Gannoruwa as it retreated from Kandy, which had been evacuated and sacked. The Portuguese were surrounded with all escape routes blocked. The Sinhalese attack was decisive, leaving only 33 Portuguese soldiers alive; the heads of the fallen were brought before King Rajasinghe II.

Consequence

The battle ended Portuguese military efforts to subjugate the Kingdom of Kandy and was the last battle fought by the Kingdom of Kandy itself. Soon afterward, the Dutch, allied with the Sinhalese, drove the Portuguese entirely from the island, ending Portuguese rule in Sri Lanka.
