The siege of Kotte was an offensive which took place during the Sinhalese–Portuguese War between 1557 and 1558. A 50,000-strong Sitawaka army led by King Mayadunne besieged Sri Jayawardenapura Kotte, the capital of Kotte Kingdom, for 12 months against a combined force of Portuguese and Lascarins led by Captain-major Dom Afonso Pereira de Lacerda. After receiving reinforcements from Mannar, Portuguese made a sally and succeeded in forcing the besiegers to withdraw. This siege marked the beginning of a series of battles between Portuguese and Sitawaka forces, and ultimately ended as Portuguese abandoned Sri Jayawardenapura Kotte in 1565.
