 After USS YORKTOWN's (CV-10) aircraft bombed Wake Island for two days, the Japanese commander, Captain (later Rear Admiral) Sakaibara Shigematsu (46) believed the Americans were about to invade and recapture the island. Sakaibara ordered all 98 civilians POWs executed on 7 October 1943. He personally beheaded one civilian POW. Tried and convicted by a military tribunal, he was hanged at Guam on June 18, 1947.
 It is not known which part the TATSUWA MARU was in but on account of age and loaded condition it is presumed the second part.
LA PEROUSE is known to have departed Singapore 0730 on 15 July 1943 for Saigon at 8.5 knots that was the likely convoy speed. It seems likely the ship would have escorted part or all of the convoy in the circumstances.
Thanks goes to Gilbert Casse of France.
