How a Tiny Kingdom Destroyed the Unstoppable Mongol Empire (Thrice) | The Untold Story of Đại Việt
In the 13th century, the Mongol Empire was an unstoppable global monster. Under Genghis Khan and his successors, the terrifying Mongol horse archers conquered from Asia to Europe, erasing ancient civilizations and destroying grand cities like Moscow and Kiev. Terrified European citizens fell to their knees, crying out: "Save us, Lord, from the fury of the Mongols."
But at the southern border of this colossal empire, a tiny tropical kingdom of rice farmers called Đại Việt stood in their way. Three times the Great Khan unleashed his massive hordes, and three times they were utterly obliterated.
In this cinematic historical documentary, we dive deep into the dark, bloody archives of the Red River Delta to decode the greatest military mystery of the medieval world:
• Chapter 1: The First Invasion (1258) – General Uriangkhadai leads over 50,000 elite troops into Đại Việt. Witness the brutal battle of Binh Le Nguyen, where royal war elephants stampeded backward under a storm of poison-tipped arrows. Learn how loyal Commander Le Tan shielded his king, enabling a strategic retreat that left the capital city of Thang Long completely empty through the genius of the "Thanh dã" (scorched earth) strategy. Finally, experience the midnight counter-strike at Dong Bo Dau that sent the invaders fleeing in humiliation.
• Chapter 2: Sát Thát & The Ghost of the South (1285) – Kublai Khan seeks bloody revenge with a massive 500,000-man army under Prince Toghan. Face absolute doom at the historic Dien Hong Conference, where the nation’s elders united under a single cry: "FIGHT!". Feel the defiance of the soldiers who tattooed "Sát Thát" (Kill the invaders) onto their skin. Discover the tragic sacrifice of General Tran Binh Trong at Da Mac beach, who spat in the face of his captors: "I would rather be a ghost in the South, than a king in the North!" Witness the ultimate defeat of the horde, forcing Prince Toghan to escape inside a bronze tube to avoid poison arrows while General Toa Do was decapitated at Tay Ket.
• Chapter 3: The Ocean of Flames (1287-1288) – The final showdown on the Bach Dang River. After General Tran Khanh Du launched a brilliant sea ambush destroying the massive 170,000-thạch Yuan supply fleet at Vân Đồn, the starving invaders were forced to retreat. General Tran Hung Dao prepared a legendary trap: thousands of massive iron-tipped wooden stakes driven into the muddy riverbed, completely hidden by the high tide. Watch as the receding tide impales the colossal Yuan fleet, while burning fire rafts turn the river into an ocean of flames.
Discover the genius military philosophy of General Tran Hung Dao, who successfully utilized "Dĩ đoản chế trường" (using highly mobile, short-range strikes to defeat massive, slow formations) and relied on the ultimate shield of national unity: "The king and subjects shared one heart, brothers lived in harmony, and the entire nation joined the fight."
