Result

The Portuguese fort fell to the Dutch and Kandyan forces.

01A fort on Koneswaram’s rock

Koneswaram, the temple of Shiva on the headland at Trincomalee, is praised in the Tevaram hymns of Sambandar and Sundarar and counted among the holiest shrines of Lanka. In April 1622, on the Tamil new year, Constantino de Sá had it plundered and thrown down, and its stones were used to build a fort across the headland. Seventeen years later that fort was the next target of the Dutch–Kandyan alliance after Batticaloa.

02The Dutch take it

In May 1639 a Dutch fleet landed troops at Trincomalee while Kandyan forces closed in by land. The Portuguese garrison was small and could not be relieved, and the fort was taken. Rajasinha had hoped the Dutch would hand the coastal forts to him, but they kept them as security for the cost of the war, the beginning of a long quarrel. Koneswaram was not rebuilt on the rock until the 20th century, after temple images were found buried nearby in 1950.

Why it matters

Trincomalee was one of the first Portuguese forts in Lanka to fall to the Dutch, who would hold the island’s coasts until 1796.
