In 1592 King Naresuan sent two different forces to the cities of Dawei and Tenasserim. The first, under the command of Phraya Chakri, had 50,000 troops to attack Tenasserim. The second unit, under the command of Phraya Phra Khlang, had 50,000 troops to capture Dawei. Dawei and Tenasserim were cities in Thailand during Sukhothai period, which the Burmese had captured. However, the Governor of Tenasserim learned of the Siamese plans and sent an urgent message to the King of Pagu, Nanda Bayin, who ordered an army to oppose the Siamese.:139-140 Tenasserim resisted the siege for 15 days while the siege of Dawei lasted 20 days, before the Siamese were successful in capturing both cities. Both consented to be subject to Ayutthaya as in the past.:140 After Phraya Chakri captured Tenasserim city, he captured Mergui and the boats in the port, which included 3 foreign sloops and 150 other boats. He then sent Phraya Thep Archun by sea to Tavoy so as to assist Phraya Phra Khlang if the Burmese advanced that far. Phraya Chakri then marched with a force of 30,000 to Tavoy by land, leaving a garrison of 10,000 at Tenasserim under Phraya Sri Sainarong. Simultaneously, Phraya Phra Khlang sent 100 boats and 5,000 men under Phraya Phichai Songkhram and Phraya Ram Khamhaeng to assist Phraya Chakri.:141 The Burmese had sent 200 boats and 10,000 men under the command of Samin Ubkong and Samin Phataba. This Burmese flotilla was caught in the middle of the Siamese flotillas advancing from the north and south. Many Burmese boats were sunk, some beached their boats and fled, while the rest sailed away. Saming Ubakong was killed and 500 men were captured.:141-142
