Pom Sattakop is named in the Royal Chronicles of Ayutthaya as the ‘Fort behind the Frogs.’ The Burmese occupied in 1766 CE positions at Ban Pom and Wat Ka Rong and established a stockade at Wat Phukhao Thong. Phraya Sri Suriyapaht, who commanded the Sattakop Fortress, had a large gun called the Grand Black King of Death, prepared to shoot at the new Burmese position. The King of Death was loaded with a double charge of gunpowder and two cannon balls. Only one round was fired and the large gun was temporarily disabled. Afterwards, the Siamese managed to use the cannon again and sank two Burmese fighting boats.
“One day later on Phra Si Suriyaphaha, who was the lord of the positions defending the Fort Behind the Frogs, thereupon had the gun Holy Grand King of Time and Death loaded with two charges [of gunpowder] and two cannonballs and fired at the Burmese stockade at the Monastery of the Gold Mountain. Now they were able to fire [just] one round forth [before] the gun accordingly cracked.” [4]
The fort stood at the mouth of Khlong Fang on its north bank. It overviewed the confluence of the waters coming from the northwest (old Bang Kaeo River and Maha Phram Canal) and the Lopburi River. The Sattakop fort was a single bastion, a bulwark outward from the city wall.
Presumably, after the Burmese attack in 1760 CE, a new bastion was built north of Fort Sattakop. The new fort is named Supharat Fort in the ‘Description of Ayutthaya’, a lengthy description of the city covering walls, forts, gates, ferries, roads, bridges, checkpoints, customs posts, markets, craft settlements, temples, and palaces, probably compiled in the early Bangkok period. The reason for the construction of this extra fort is unknown to me.
The Supharot Fort is found on the 19th-century map and Phraya Boran Ratchathanin’s map of 1926 CE. On the 1974 CE Fine Arts Department map, it becomes part of a large fort with two bastions connected by a curtain with battlements. The Sattakop Gate was situated between the two bastions. Wat Khok was located behind the fortification. On the road in front of the Sattakop Gate, there was a fresh market. [5]
Most parts of the wall and the fortresses were dismantled in the reign of King Rama I, who had the bricks taken to construct the new capital in Bangkok. [6]
