If any non-Thai speakers stumble upon this video, let me explain - this segment of a theatre play "Legend of King Naresuan" features Mingyi Swa, Burmese prince (son of king Nanda Bayin, formally titled Uparaja, which is technically rather a viceroi, than a prince) inspecting the troops before the battle of Nong Sarai (1593). Historically, Mingyi Swa fell in said battle, though Thai sources claim there was a formal elephant duel between him and King Naresuan, while Burmese sources claim he was killed by an explosive shell from an Ayutthayan mortar.
