After the war of 1548, Maha Chakkraphat insisted on battling Burmese armies near Ayutthaya, so he heavily fortified the city. He, however, de-fortified other cities in order to prevent the Burmese from taking them as bases. The census was taken to derive all available manpower to war. The arms and horses and elephants (white elephants) were caught and accumulated in the full-scale preparation for war.
