47 Ships Sunk by Kamikaze Aircraft. by Bill Gordon. Sources differ regarding the number of ships sunk by kamikaze aircraft during World War II. Inoguchi (1958, 211-34) lists the names of 34 ships sunk by kamikaze attacks, and Warner (1982, 323-34) gives the names of 57 ships sunk by special attack aircraft. However, an examination of other historical records indicates that both of these two lists do not have the correct number of ships sunk by kamikaze.
Sinking ships without warning. German's sunk the Bristish passenger ship Lusitania May 1915. 1200 killed included 130 Americans. Wilson demanded reparations and apology. Bryan instructed to send memo to Germany, hesitant, but did. Germans said Lusitania was armed (false) and carrying military cargo (true, British was using civilians to shield war cargo). Bryan refused to write 2nd note and resigned as Sec of State.
