Martaban, a thriving Mon port town, will be difficult for Tabinshwehti to subdue, supported as it is by Portuguese soldiers and arms and defended on the land side by strong fortifications backed with earthwork and on the water side by seven Portuguese ships under Paulo Seixas.

Martaban tries to negotiate surrender when supplies run out, but Tabinshwehti will accept only a complete surrender.

Martaban tries without success to lure away Tabinshwehti’s Portuguese mercenary commander Joano Cayeyro.

Finally, Tabinshwehti uses fire rafts to burn and drive away the ships guarding the water side of the fortifications, then maneuvers a high fortress raft armed with guns and cannons to a position in front of the river side fortifications.

The attackers clear the walls of defenders and launch a final assault on the town.

(Pinto records in detail the pillaging and executions that supposedly took place in the wake of the defeat after seven months of siege.)
