21 March 1945:
South China Sea. Off Nha Trang, Indochina. At about 1120, convoy HI-88-I is attacked by Fifth Air Force B-25 "Mitchell" medium-bombers of the 345th Bomb Group’s 501st Bomb Squadron. TATEISHI is hit by at least one, and possibly two, of three 500-lb bombs dropped by a B-25 and sinks at 11-50N, 109-18E.
The planes also sink cargo vessels MOTOYAMA MARU No. 1 and FUSHIMI MARU and subchaser CH-33. The B-25's damage small oiler TAKASAGO MARU NO. 6 and subchaser CH-9. CH-20 and damaged CH-9 take refuge at Nha Trang.
At 1120, USN codebreakers intercept and decrypt a message from CH-33 that reads: “Engaging 15 B-25s. CH-33 and FUSHIMI sank.” Codebreakers decrypt another message that reads: “At 1100 in position 12-03N, 109-00E convoy HI-88I . . .”
CH-33 sunk and “CH-9 is to ---anchor off Natoran at 1200----. Killed in battle: Captain and 7 others. Wounded: 222 men.” A later Japanese report amends the location of this attack to 12-30.7N., 109-14.3E.
During the attack, one B-25 is shot down near TATEISHI. Four men are seen in a life raft about two miles from shore. Three are captured by the Japanese, one of whom dies of wounds shortly thereafter. About a month later, a Kempei-tai (military police) NCO beheads the remaining two B-25 crewmen.
