On January 26, 1943, the submarine USS "Wahoo" fired on survivors in lifeboats from the Japanese transport "Buyo Maru". Vice Admiral Charles A. Lockwood asserted that the survivors were Japanese soldiers who had turned machine-gun and rifle fire on the "Wahoo" after she surfaced, and that such resistance was common in submarine warfare. According to the submarine's executive officer, the fire was intended to force the Japanese soldiers to abandon their boats and none of them were deliberately targeted. Historian Clay Blair stated that the submarine's crew fired first and the shipwrecked survivors returned fire with handguns. The survivors were later determined to have included Allied POWs of the Indian 2nd Battalion, 16th Punjab Regiment, who were guarded by Japanese Army Forces from the 26th Field Ordnance Depot. Of 1,126 men originally aboard "Buyo Maru", 195 Indians and 87 Japanese died, some killed during the torpedoing of the ship and some killed by the shootings afterwards.
