Siem Reap
The Thai army managed to defeat the Burmese, who quickly retreated through the pass. Maha Chakkraphat's thoughts then turned to Cambodia. Not only had Ang Chan attacked and looted Prachinburi, turning its people into slaves, but he also refused to give Maha Chakkraphat a white elephant he had requested, rejecting even this token of submission to Siam. Maha Chakkraphat ordered Prince Ong, the governor of Sawankhalok, to lead an expedition to punish Ang Chan and recover the Thai captives. The rival armies met, and Ang Chan killed Prince Ong with a lucky musket shot from an elephant's back. The leaderless Thai army fled, and Ang Chan allegedly captured more than 10,000 Siamese soldiers. To celebrate his great victory, King Ang Chan supposedly named the battleground "Siem Reap", meaning 'the total defeat of Siam'.
