The above video is an American US Navy film recording the legitimate engaging, attacking, and sinking of the Imperial Japanese Navy Ship – designated the “Buyo Maru – sunk off the coast of New Guinea (in transit to Rabaul) on January 26th 1943. With hundreds of “unarmed” Imperial Japanese soldiers and sailors in the water (or in lifeboats) – Captain Dudley Morton then surfaced the USS Wahoo and ordered his crew to open-fire on the survivors using Deck-Guns. Captain Morton also ordered that this action be “filmed”.
