The invasion initially met little resistance, as the Burmese force was too large for the small guard posts on the border.[2] Upon hearing of the Burmese invasion, Maha Chakkraphat mobilized his kingdom, then gathered his forces at Suphanburi, a town just west of Ayutthaya.[3] When Tabinshwehti and his Burmese army arrived at the walled town of Kanchanaburi, they found it deserted.[4] The King of Burma then continued his march eastward, capturing the villages of Ban Thuan, Kaphan Tru and Chorakhe Sam Phan.[4] Tabinshwehti divided his army into three columns, the first commanded by Bayinnaung, the second by the Viceroy of Prome, and the third by Yong, the Governor of Bassein.[5] The Burmese continued their advance and captured the ancient town of Uthong as well as the villages of Don Rakhang and Nong Sarai and closed on Suphanburi. When the Burmese attacked the town, the Siamese defenders could not withstand the onslaught and retreated towards Ayutthaya. Tabinshwehti ordered his army southeast along two canals, and crossed the Chao Phraya River near Phong Phaeng. From here he encamped his army directly north of the Siamese capital of Ayutthaya on a field called the Lumpli Plain.[4]

Maha Chakkraphat left the capital with his forces to engage Tabinshwehti and test Burmese strength. On this occasion, he mounted his chief war elephant. Accompanying him were his Chief Queen, Sri Suriyothai, and one of their young daughters, Princess Boromdhilok, the two riding together on a smaller war elephant. Both royal ladies were dressed in male military attire (helmet and armour), with the queen wearing the uniform of an Uparaja. Also accompanying their father on elephant mounts were two sons, the Uparaja and heir apparent, Prince Ramesuan, and his brother Prince Mahin.[4][6]

The Siamese army under Maha Chakkraphat soon met the advance column commanded by the Viceroy of Prome, and the two armies engaged in battle. The commanders of the two forces engaged in single elephant-combat, as was the custom of the time.[7] Maha Chakkraphat's elephant panicked and gave flight, charging away from the enemy, the viceroy giving chase. Fearing for the life of her husband, Queen Sri Suriyothai charged ahead to put her elephant between the king and the viceroy, thereby blocking his pursuit.[6][8] The viceroy then engaged the queen in single combat, fatally cleaving her from shoulder to heart with his spear, also mortally wounding her daughter. Both mother and child met their deaths on the back of the same elephant.[8][9][10] It was said that the viceroy did not know he was fighting a woman until his blow struck. As she fell dying, her helmet came off, exposing her long hair. Burmese chronicles do not mention any instance of single combat (on elephant-back or otherwise) by the Viceroy of Prome.[note 1]

Prince Ramesuan and Prince Mahin then urged their elephants forward to fight the viceroy, and drove him and his remaining forces from the field, then carried the bodies of their mother and sister back to Ayutthaya. The Siamese king meanwhile rallied his army, and retreated in good order back towards the capital.[6][8]
