Bang Rajan (2000)

Set right before the fall of Thailand's old capital, Ayuttaya, Bang Rajan draws on the legend of a village of fighters who bravely fended off the Burmese armies. In 18th century, when King Mangra ascended the Burmese throne, he sent a huge army to attack the former Thai capital city of Ayutthaya by two different routes. But the small village of Bang Rajan chose to sacrifice their own lives before becoming slaves to the Burmese empire. With no support from the Royal army, the villagers drives the invading Burmese away many times until their names have become legendary during the time. As each subsequent battles becomes fiercer, the villagers tries to forge a canon to battle the enemy in a final battle where everyone, women and children included, have to fight in combat.
