On Tuesday, 7 April 1767 CE, at 15.00 Hr, the Burmese set fire to the base of the city wall on the edge of the Maha Chai Fortress. All Burmese stockades began firing their heavy guns into the city. At dusk, the city wall collapsed. At 20.00 Hr, the Burmese commander ordered a general attack, during which the Burmese scaled the walls on all sides of the city. At the point where the city wall crumbled, the Burmese entered the city around midnight. Ayutthaya turned to ashes.
A detail out of the Royal Chronicles of Ayutthaya explains:
“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.” [2]
On the south side of the road, in front of Wat Mae Nang Pluem, some remnants of the Burmese fortifications are still visible [3]. Two earthen mounds of a stockade, used by the Chinese as burial mounds after the city's fall, are among the last surviving witnesses to the 1767 CE tragedy.
