*On 26 of January 1943, Wahoo and her crew were involved in a controversial incident where the survivors of the Japanese transport ship ''Buyo Maru'' were attacked in the water. Though there are conflicting accounts on who had engaged first, several survivors were gunned down in the water and on lifeboats.
