Ultimately, more than 60,000 Filipino and 15,000 American prisoners of war were forced into the Bataan Death March. However, about 10,000–12,000 of these eventually escaped from the march to form guerrilla units in the mountains, tying down the occupying Japanese. On 7 September 1944, the Japanese ship "Shinyō Maru" was sunk by USS "Paddle"; on board the "Shinyo Maru" were U.S. POWs, of whom 668 died and 82 survived.
