However the Burmese referee said the Burmese champion was too distracted by the dance, and declared the knockout invalid. The King then asked if Nai Khanomtom would fight nine other Burmese champions to prove himself. He agreed and fought them all, one after the other with no rest periods in between. His last opponent was a great kickboxing teacher from Rakhine. Nai Khanomtom mangled him by his kicks and no one else dared to challenge him.
King Mangra was so impressed that he allegedly remarked, "Every part of the Siamese is blessed with venom. Even with his bare hands, he can fell nine or ten opponents. But his Lord was incompetent and lost the country to the enemy. If he had been any good, there was no way the City of Ayutthaya would ever have fallen." [18]
King Mangra granted Nai Khanomtom freedom along with either riches or two beautiful Burmese wives. Nai Khanomtom chose the wives as he said that money was easier to find. He then departed with his wives for Siam. Other variations of this story had him also winning the release of his fellow Thai prisoners. His feat is celebrated every March 17 as Boxer's Day or National Muay Boran Day in his honor and that of muay boran's.
