The chronicles recount that Nemiao Sihabodi, the General of the Burmese Armies, at the end of 1766 CE, sent soldiers to establish an enclosure at the Monastery of the Crying Crow to build tall forts with bastions so that they could fire their large guns at the City of Ayutthaya. The Siamese attacked the Burmese with a boat army. One of their leaders was dancing with a sword in hand in front of the boat, probably showing the Burmese they were not feared, protected by occult incantations. However, he was shot at by the Burmese and fell into the water, whereupon the whole boat army retreated to the city.
“[Posuphla] advanced forward and established his stockade at the Three Fig Trees. Then he sent men to establish stockades at the Village of the Fort and the Monastery of the Landing of the Crying Crow and built tall forts.” [2]
The Burmese fort at Wat Ka Rong was one of the forts which started the last cannonade of Ayutthaya. The Chronicles mention that on Tuesday, the 9th day of the waxing moon, at four o'clock in the afternoon, the large canons of the forts at the Tha Ka Rong Monastery fired their deadly load on the Royal city. At the same time, combustibles were set alight under the foundations of the defence walls at Hua Ro, beside the Maha Chai Fort. The defence wall collapsed around eight o'clock in the evening, and the Burmese made their final assault. Ayutthaya fell that night, never to arise.
"Reaching 1129 of the Royal Era, a year of the boar, ninth of the decade, and arriving at a Tuesday, the ninth day of the waxing moon in the fifth month, the ninth day and middle day of the New Years Festival, the Burmese lighted fires to burn the combustible firewood under the foundations of the walls opposite the Head of the Sluice beside the Fort of Grand Victory, and the Burmese in the stockades of the Monastery of the Crying Crow and of the Monastery of the Jubilant Lady, as well as in each and every other stockade, lit [the fuses of] their great guns—the guns in the forts and in the bastions—and simultaneously fired them on into the Capital in volleys from a little past three mong in the afternoon until dusk. As soon as the walls where they had lit the combustible firewood to consume the foundations had collapsed somewhat, around the second thum, they thereupon had [the fuse of] the signal gun lit. The Burmese troops of each brigade on each side who had been prepared, having accordingly taken their ladders and simultaneously leaned them against the places where the walls had collapsed and against other places all around the Holy Metropolis, climbed them and were able to enter the Capital at that time. Now they lit fires in every vicinity and burned down buildings, houses, hermitages and the Holy Royal Palace Enclosure, including the palaces and royal domicile. The light of the conflagration was as bright as the middle of the day. Then they toured around to chase and capture people, and to search out and confiscate all their various sorts of valuables, [whether] silver, gold, or [other] belongings." [3]
