In 1544, the armies of King Tabinshwehti of Burma invaded and took Sandoway, beginning the Toungoo–Mrauk-U War. However, he was unable to march further, and was held there for two years. Thus, he brought in Talaing and Shan fighters and revitalized his offensive, marching north to Mrauk U. However, once he reached the city, Tabinshwehti retreated, as he it was too well-defended and he did not want to besiege or blockade it.
