Following the death of their
father, the first and the second born, led their armies to Ayutthaya in order to claim the
throne. Both princes engaged each other in personal combat, mounted on elephant; on
or near the “charcoal market” bridge (Saphan Pa Than). Both were severely wounded,
their throats slashed open at the same time and died in combat. The youngest brother,
Chao Sam Phraya, was then invited to Ayutthaya and proclaimed King under the title of
Borommaracha II. The King commanded two chedis built on the site where his brothers
engaged in battle. He cremated both his brothers and on their cremation site Wat Racha
Burana (1) was built.
