Aceh Sultanate
Around that same time period, the Sultanate of Aceh had grown into a regional power with a formidable naval force and regarded Portuguese Malacca as potential threat. In 1629, Iskandar Muda of the Aceh Sultanate sent several hundred ships to attack Malacca, but the mission was a devastating failure. According to Portuguese sources, all of his ships were destroyed and lost some 19,000 men in the process.
