Japan’s Last Lifeline Convoy — How the US Navy Hunted It Down

On January 12, 1945, Task Force 38 found convoy Hi-86 off French Indochina—and wiped it out in hours. But was this really Japan's last lifeline, or the final symbol of a blockade already won? This full WWII documentary follows the evidence behind the South China Sea raid: how American intelligence tracked the convoy, why Japan's oil routes were already collapsing, and what the loss of Hi-86 truly meant for the empire's ability to keep fighting. From the morning strike to the death of the cruiser Kashii and the carnage at Cam Ranh, we separate the real scale of destruction from the legend. 0:00 The Destruction of Convoy Hi-86 1:39 Ambush at Sea 6:32 The Fuel Crisis 14:17 Halsey's Bold Gamble 20:22 The Intelligence Net 26:36 The Doomed Fleet 34:07 The Morning Strike 41:20 Death of Kashii 48:07 Carnage at Cam Ranh 54:10 Tallying the Ruin 60:35 The Severed Lifeline If you enjoy deep-dive Naval history, subscribe for more WWII documentaries.
