The Burmese–Siamese War (1568–1569) also known as the War of the first fall (สงครามคราวเสียกรุงครั้งที่หนึ่ง) was a military conflict fought between the Kingdom of Ayutthaya (Siam) and the Kingdom of Burma. The war began in 1568 when Ayutthaya unsuccessfully attacked Phitsanulok, a Burmese vassal state. The event was followed by a Burmese intervention which resulted in the 2 August 1569 defeat of Ayutthaya, which became a Burmese vassal state. Burma then moved towards Lan Xang, occupying the country for a short period of time until retreating in 1570.

Background

In 1485,

overtaking Hanthawaddy and cementing Toungoo's status as an empire.[4]

Internal struggles over the control of the

Tavoy, while Ayutthaya managed to protect the rest of its territory.[5][6][7]

A second

Sawankhalok, Kamphaeng Phet, and Sukhothai thus turning them into tributary states, denying Ayutthaya valuable allies. Ayutthaya's capital was then sacked, while Maha Chakkraphat was forced to become a priest in Bago, Burma. However, he was soon allowed to return home on a pilgrimage during which he abandoned priesthood and returned to power.[8][9][10][4]

Conflict

Prelude

In 1568, Ayutthaya king

Mahathammarachathirat
. When Mahathammarachathirat asked Ayutthaya for assistance Maha Chakkraphat dispatched general Phya Siharat–Dejo, tasking him with detaining Mahathammarachathirat. Siharat–Dejo instead remained in Phitsanulok and disclosed Maha Chakkraphat's true intentions, pushing Burma into an armed intervention.

Siege of Phitsanulok

A Burmese force broke through the Lao lines and joined the defenders of Phitsanulok which was besieged at the time. In the meantime, an Ayutthayan army advanced on Phitsanulok under the guise of reinforcements. Upon their arrival the Ayutthayans were asked to stay outside the city, on the same night the Phitsanulokans launched flaming rafts on the Ayutthayan fleet, destroying it. The losses prompted both the Lao and Ayutthayans to break the siege and retreat, the Lao troops later ambushed and annihilated a Burmese force that attempted to chase them.[11][12]

During the course of his retreat, Maha Chakkraphat unsuccessfully attacked Kamphaeng Phet. His plans changed however when he learned that Mahathammarachathirat was on an official visit to Burma, causing him to return to Phitsanulok. The Ayutthayans then proceeded to kidnap all of Mahathammarachathirat's family but his son Prince Naresuan who was accompanying his father. The kidnapping was to dissuade Phitsanulok from launching counter-attacks on Ayutthaya, nonetheless this act led the Burmese to initiate a joint invasion of Ayutthaya with the help of their Thai puppet states.[13]

Having gained the support of northern Thai states,

Phetchabun. The Lan Xang forces prevailed at which point one of the commanding generals from Nakhon Phanom broke south toward Ayutthaya. The Burmese rallied and were able to destroy the divided forces, and King Setthathirath had to retreat toward Vientiane.[14]

Siege of Ayutthaya and Vientiane

Siege of Ayutthaya

The Burmese then laid siege to Ayutthaya city. After heavy cannon fire put a stop to Burmese attempts at digging up to the walls, the invaders began building a bridge at Koh Keo in order to access the walls from a new direction. Maha Chakkraphat died during the course of the siege, therefore his son Mahinthrathirat ascended the throne. Frequent Ayutthaya sorties once again prevented the Burmese from finishing the construction. Bayinnaung then sent an Ayutthayan noble he held captive under the guise of a deserter. Not only was the spy allowed into the city but he was also put into a position of power. On the night of 7 August 1569, the spy opened the gates of the city, bringing its downfall. The Burmese army sacked the city. Mahinthrathirat along with his family and the nobility were captured and taken to Pegu. Mahinthrathirat died on the way in the same year.[15]: 63  Ayutthaya became a Burmese vassal state, with Mahathammarachathirat appointed king.[14][4][16]

Burmese invasion of Lan Xang

The Burmese took several weeks to regroup and rest having taken Ayutthaya, which allowed Lan Xang to rally their forces and plan for prolonged

Nam Ngum, northeast of Vientiane. In 1570, after having no success against the Laotian guerrilla forces, Bayinnaung retreated and was chased by the forces of Setthathirath. The Laotians were able to capture 30,000 troops, 100 elephants, and 2,300 pieces of ivory from the Burmese.[16]
