19 April 1944: Allied Operation "Cockpit":
Sumatra, Indian Ocean. In the first combined operation between Admiral James Somerville's, (Commander-in-Chief, Eastern Fleet) British Pacific Fleet and the USN Pacific Fleet, carrier aircraft from HMS ILLUSTRIOUS and USS SARATOGA (CV-3) attack Sabang, NEI. The strike force is made up of 17 "Barracudas" (No. 810 and No. 847 Sqdns) and 13 F4U "Corsairs" (No. 1830 and No. 1833 Sqdns) from HMS ILLUSTRIOUS and 11 TBF "Avengers", 18 SBD "Dauntlesses" and 24 F4F "Hellcats" (VT, VB and VF-12) from USS SARATOGA.

The strike force encounters no air opposition and flak only after the attack is well under way, indicating total surprise. The planes damage HATSUTAKA and sink transports HARUNO (ex Dutch KIDOEL, one crewman killed), and KUNITSU MARUs. Oil storage tanks also are destroyed and heavy damage is inflicted on port facilities. The Corsair and Hellcat pilots claim 24 aircraft destroyed on the ground in a suppressive sweep over nearby Lho Nga airfield. The only Japanese response is an attack by three G4M "Betty" torpedo bombers, all of which are splashed by a Combat Air Patrol from USS SARATOGA.

Later that day at 0955 HATSUTAKA departs port for Penang.

At 1646, USN codebreakers intercept and decrypt a message from HATSUTAKA that reads: “Scheduled to arrive Penang at 1230, 20th. Request arrangements be made for the following: 1. Necessary repairs to the following damage: (lists damage to transmitter, searchlights, and holes in hull ----). 2. Killed in action 3, Patients 5. 3. ---.”

1 May 1944:
Off the coast of Malaya. That evening, an enemy submarine's periscope is spotted a mere 30 m off AMAGIRI MARU's starboard flank. AMAGI MARU opens fire and the escorts drop two DCs. Two torpedo tracks are sighted, but AMAGI MARU successfully evades them.

2 May 1944:
Auxiliary minesweeper KYO MARU No. 1 joins the convoy and replaces KEINAN MARU No. 5 that is detached. At 2240, AMAGI MARU is hit in her No. 2 hold by one of three torpedoes fired by LtCdr (later Vice Admiral, Sir) Hugh S. Mackenzie's submarine HMS TANTULUS. Four soldiers are KIA. At 2330, KYO MARU No. 1 takes off passengers and later transfers them to HATSUTAKA.

2 May 1945:
At 2155 LtCdr Benjamin C. Jarvis' (USNA ’39) USS BAYA (SS-318) and Cdr Frank D. Latta’s (USNA ’32)(former CO of USS NARWHAL (SS-167) USS LAGARTO (SS-371) SJ radar pick up four targets at 15,000 yards; a tanker, and unidentified ship and two escorts one of which is later mis-identified as a SHIRATAKA-type minelayer. At 2305, USS BAYA attacks on the surface unsuccessfully. At 2307, HATSUTAKA opens fire on USS BAYA with 20-mm, 40-mm, and 2 or 3 4.7" guns at range of 1100 yards. At 2309, Baya fires another three torpedoes in a "down the throat shot", but HATSUTAKA combs their tracks. At 2320, when HATSUTAKA turns on her searchlight, USS BAYA submerges and fires another torpedo at her, but misses again. At 2325, when USS BAYA surfaces, HATSUTAKA secures her searchlight and again commences firing on USS BAYA. At 2329, she drops six depth charges that shake USS BAYA violently. At 2333, Jarvis informs Latta that he was driven off by the escort.

3/4 May 1945:
Gulf of Siam (Thailand). After midnight, USS BAYA again attacks the tanker unsucessfully and is again driven off by the escorts. That same night, HATSUTAKA detects, depth-charges and sinks USS LAGARTO with all 86 crewmen in the Gulf's shallow waters at 07-55N, 102-00E. Early in the morning, USS BAYA attempts to contact USS LAGARTO with no success. [3]

13 May 1945:
At 1600, HATSUTAKA departs Ha-Tien, SW Indochina for Singapore escorting cargo ship TOTTORI MARU.

14 May 1945:
Gulf of Siam. At 0737, LtCdr Albert L. Becker's (USNA ’34) USS COBIA (SS-245) fires five torpedoes at a minelayer Becker misidentifies as "YAEYAMA", but two broach and HATSUTAKA combs the remaining tracks. At 1150, HATSUTAKA attacks USS COBIA not ceasing until after 1320. USS COBIA notes that HATSUTAKA apparently had two echo ranging devices, evidenced by alternate high and low note pings.

At 1430, LtCdr Frank M. Smith's (USNA ’35) USS HAMMERHEAD (SS-364) attacks TOTTORI MARU, carrying 500 tons of rice, at 10-58N, 102-24E, but she evades three torpedoes.

That same day, HATSUTAKA catches USS COBIA in shallow water and attacks with depth charges. Becker takes USS COBIA to the bottom at only about 120 feet, but USS COBIA gets mired in about 20 feet of mud. USS COBIA takes a beating and is heaviy damaged by the depth charges. After HATSUTAKA departs, Becker rocks the submarine with his electric motors and breaks free.

15 May 1945:
At 0020, lookouts aboard TOTTORI MARU spot a surfaced submarine (USS HAMMERHEAD). In high seas and poor visibility, TOTTORI MARU opens fire with her forward deck gun, followed by HATSUTAKA, scoring several near misses. At 0127, TOTTORI MARU is hit on the bow by a torpedo from USS HAMMERHEAD. At 0132, she sinks bow first at 09-58N, 101-05E. 52 crewmen are KIA. HATSUTAKA picks up 19 survivors and turns back towards Singapore.

16 May 1945:
Off the E coast of Malaya. At 0525, LtCdr Francis W. Scanland's (USNA ’34) USS HAWKBILL (SS-366) fires six torpedoes and gets two hits that damage HATSUTAKA. A sea truck takes her under tow stern first towards the mainland, but Scanland attacks and fires three more torpedoes at her from over 4,600 yards. HATSUTAKA is hit, breaks in two and sinks at 04-49N, 103-31E. Her surviving crewmen refuse rescue. LtCdr Ozaki Takashi (60) survives. He is later promoted Cdr.

23 May 1945:
At 1525, USN codebreakers intercept and decrypt a message from the CO of HATSUTAKA that reads: “At and after 0530 on the 16th of May, 3 torpedoes were fired (one direct hit in the engine room, navigation impossible). At 1100 we received a second torpedo attack and sank six miles off Zungun --. ” At 1625, USN codebreakers intercept and decrypt another message from HATSUTAKA that reads: “HATSUTAKA action summary. ----- Between 0020 and 0215 on the 15th engaged 6 submarines. Kept down two of them and inflicted considerable damage, but TOTTORI MARU was sunk by the others -----.”

10 August 1945:
Removed from the Navy List.

3 April 2008:
NW of Pulao Tenngol, Malaya. A team of divers from Davy Jones' Locker Co. of Koh Tao, Thailand, locates the wreck of HATSUTAKA. The wreck was found N of Dungun, about one kilometer off shore. The bow section is lying on its port side, measuring about 45m in length. This forward section lies on a roughly N-S orientation. The stern sits upright, about 25m off the bow section, extending west, towards the mainland.


Author's Notes:
[1] General note: HATSUTAKA was used as a fast transport in the Indian Ocean area for much of her career

[2] For action details see trom of destroyer AKIZUKI.

[3] On 19 May 2005, USS LAGARTO was located in the Gulf of Thailand by Wreck Research Vessel MV TRIDENT based at Koh Tao, Thailand. The wreck is mostly intact and sitting upright in about 70 m/225 ft of water. The stern is shrouded in Thai fishing nets. Forward starboard torpedo door No. 4 is partially open and empty that suggests USS LAGARTO went down fighting and fired a torpedo during her last moments. Also visible forward of the conning tower port quarter is massive damage. A hole about 18 feet high and 8 to 9 feet wide is on the port side, near the forward torpedo room.

Clearly, USS LAGARTO sustained a direct hit from a depth charge that completely destroyed her external steel plating. The sub's external control planes are juxta-positioned; the foreword planes are set to the ‘dive’ position whereas the stern planes are set to ‘surface’. The rudder is positioned at hard right. All of USS LAGARTO's hatches are closed.

Thanks go to Matthew Jones of Mississippi for assistance with COs. Thanks also go to the late John Whitman of Virginia, USA for info on CNO intercepts of Japanese messages and to Mr. Gilbert Casse of France and Berend van der Wal of Netherlands for general assistance.
