Tabinshwehti
Martaban (1540–1541)

Tabinshwehti next tried to complete his control of Lower Burma. In 1540, he issued an ultimatum to Martaban, the last holdout, to surrender in exchange for amnesty. However, the offer was promptly rejected by the wealthy port's ruler Saw Binnya, who had heavily fortified his city and enlisted several Portuguese naval and land mercenaries. In November 1540, 13,000-strong Toungoo land and naval forces attacked the city. For seven months, Martaban's Portuguese-led defenses kept besiegers at bay. Finally, right before the rainy season in May 1541, Adm. Smim Payu 's flotilla broke through the seven Portuguese warships guarding the harbor, and the city fell. The sack raged for three days. Tabinshwehti ordered a whole scale execution of the viceroy, his family, and all the "gallant" defenders for they had refused his prior offer of amnesty. The mass execution had the desired effect. The governors of Moulmein (Mawlaymyaing) and southern territories (present-day Mon State), abutting then Siamese frontier submitted. He appointed Saw Lagun Ein, brother-in-law of Takayutpi, as viceroy of Martaban.
