East China Sea. LtCdr (later Cdr) David C. White's (USNA ’27) USS CERO (SS-225), LtCdr (later Captain) Edgar J. MacGregor's (USNA ’30) USS SHAD (SS-235) and LtCdr John A. Moore's (USNA ’32) USS GRAYBACK (SS-208) are patrolling W of Okinawa. The three submarines had formed up at Midway under SubRon 2's Captain (later Vice Admiral) Charles B. Momsen (USNA ’19) as the first of COMSUBPAC's wolfpacks. They receive an "Ultra" signal based on code-breaking intelligence that alerts them that a convoy will pass through their patrol area.[1]

At 1627, Moore's submerged USS GRAYBACK spots the masts of the convoy north of her position. USS GRAYBACK tracks the convoy, but loses it at 1800 in the darkness. Moore surfaces and acquires the convoy on his SJ radar.

22 October 1943:
Off Kirun, Formosa (now Keelung, Taiwan). LtCdr Moore makes a long "end-around" run and sets up ahead of the convoy. At 0327, USS GRAYBACK submerges. At 0347, the submarine fires six torpedoes. Four torpedoes hit AWATA MARU. One touches off a magazine and creates an enormous explosion. AWATA MARU sinks N of Miyako-jima at 26-32N, 125-05E. 1,087 men of the 17th Division and 223 navy crewmen are KIA. MAIKAZE and NOWAKI unsuccessfully counterattack. Later, the destroyers rescue 76 troops and 88 crewmen. HIE MARU escapes and makes for Rabaul via Truk.

At 1045, USN codebreakers at Fleet Radio Unit, Melbourne, Australia (FRUMEL) intercept and decode a message from the 4th Destroyer Division that reads "When No 3 Group and TEI 4 Transport Force were at 24-45N, 125-00E at 0348 on 22nd October course 150 degrees speed 14 knots, AWATA MARU was hit by 4 torpedoes from an enemy submarine and sank immediately. MAIKAZE attacked whilst NOWAKE searched. Good contact obtained but result unknown. Picked up survivors at 0940 and resumed passage to Rabaul.

11 November 1943:
190 miles NNW of Kavieng, New Ireland. LtCdr (later Captain) Delbert F. Williamson's (USNA ’27) USS DRUM (SS-228) is on patrol between the Carolines and New Ireland to intercept expected Japanese reinforcements during the forthcoming invasion of Tarawa. Alerted by an Ultra message, Williamson sights a convoy, sets up and fires six Mark-14 steam torpedoes at HIE MARU at 01-00N, 149-20E. The first torpedo explodes prematurely. Transport KANAYAMASAN MARU reports three torpedo explosions astern. NOWAKE counterattacks unsuccessfully. The convoy suffers no damage in the attack.

At 1029 that day, a USAAF Fifth Air Force B-24 "Liberator" bombs the convoy and damages HIE MARU. 31 crew and passengers are KIA, 28 badly wounded, 110 lightly wounded.

17 November 1943:
385 miles SW of Truk. LtCdr (later Captain) Delbert F. Williamson's (USNA ’27) USS DRUM again sights and identifies HIE MARU steaming in the convoy. At 1245, in a submerged attack, Williamson fires four torpedoes at HIE MARU. Only one hits in hold No. 3. HIE MARU takes on a list to port. The escorts mount a heavy counter-attack that almost sinks USS DRUM. Depth charges knock paint off her bulkheads.

At 1250, USN codebreakers intercept a message from HIE MARU that reads: “At 1245, November 17, in position 01-45 N, 148- [blurred print] E. received 1 torpedo hit in No. 3 hold; No. 2 and No. 3 holds flooded. At present no danger of sinking. -----.”

At 1730, HIE MARU sinks at 01-45N, 148-45E. There are no casualties among the 3,000 troops aboard. The other ships in the convoy are unscathed.
