Wat Sop Sawan is mentioned in Royal Chronicles as it relates to warfare. Burmese
armies set up a number of stockades west of the city. One of these Burmese stockades
was situated directly across the river from Wat Sop Sawan (where Wat Thammaram is
located today). This strategic position put Burmese cannons within firing range of the
Rear Palace (Wang Lang). As a result, Siamese troops dragged armaments to an
embrasure at the Wat Sop Sawan corner and fired into the middle of the Burmese army.
Cannon balls killed many elephants, horses, and soldiers (Cushman 60-61).
