I-65 departs Sasebo for Palau with Admiral Daigo's flagship, light cruiser YURA, and SubDivs 29 and 30. Enroute, SubRon 5 is diverted to Samah, Hainan Island, China.

5 December 1941:
Departs Samah, with ComSubDiv 30 Captain Teraoka aboard, on her first war patrol to cover the invasion transports.

9 December 1941:
SE of Indochina near Poulo Condore Island (05-00N, 105-30E). At 1415 (local), I-65 reports sighting "two enemy battleships, course 240, speed 14 knots" to SubRon 5 aboard YURA. This is Vice Admiral Sir Tom Phillips' Force "Z's" new battleship HMS PRINCE OF WALES, old battlecruiser HMS REPULSE, destroyers HMS ELECTRA, EXPRESS, TENEDOS and Australian destroyer HMAS VAMPIRE. Phillips had sortied from Singapore to find and attack the Malaya invasion transports.

LtCdr Harada's report is received by YURA, light cruiser KINU and the 81th Naval Communications Unit in Saigon. The reception is poor and YURA needs another 1.5 hours to decode and relay the message to Vice Admiral Ozawa Jisaburo aboard flagship CHOKAI.

I-65 surfaces and starts a tail chase but a sudden squall cloaks the British ships. While Harada continues the chase, a Kawanishi E7K "Alf" from the KINU buzzes I-65, mistaking it for an enemy submarine. Harada crash-dives. When he surfaces 30 minutes later, the contact with Phillips' force is lost.

18 March 1944:
Indian Ocean, SW of Colombo. I-165 torpedoes 3,916-ton British armed merchant NANCY MOLLER (ex-ROWENA, NORFOLK) enroute from Durban with a cargo of coal to Colombo, Ceylon. She goes down rapidly after two hits to port side at 02-14N, 78-25E. I-165 surfaces about 50 yards from the lifeboats and attempts to establish the identity of the ship. Six men from one boat ared ordered aboard the submarine and Able Seaman Gunlayer Dennis Fryer is taken POW.

Two Chinese sailors are shot, but three Lascars from the same boat are released. Before departure, I-165 circles the wreckage of NANCY MOLLER, spraying it and the survivors with machine-gun fire.

24 June 1944:
Biak is defended by a regiment of the IJA's 36th Division and the IJN's 28th Base Force. After Operation "Kon" is cancelled, the C-in-C of the 4th Southern Expeditionary Fleet, Vice Admiral Yamagata Seigo (former CO of CV HOSHO) requests that three submarines be sent to evacuate the staff officers. I-165 is the only one available at that time.

5 July 1944:
Returns to Surabaya, where some officers and sailors are rotated.

24 July 1944:
Departs Surabaya for a rescue mission to Biak but has to return because of mechanical troubles.

12 August 1944:
I-165 departs Surabaya for a rescue-supply mission to Korim Bay, Biak, via Ambon Island, Netherlands East Indies, carrying supplies and ammunition including 80 supply drums, of which 60 are lashed to her deck.

18 August 1944:
LtCdr Shimizu attempts to contact the troops at Korim Point, but there is no answer. He proceeds to the reserve area N of Wardo Bay where three „subchasers” (probably Fairmile B motor launches from the RAN New Guinea Motor Launch Flotilla based at Mios Woendi) attempt to contact her with blinker signals around 1630 (JST). LtCdr Shimizu crash-dives to 200 ft (60 m) immediately.

I-165 is heavily depth-charged and soon develops a major leak to her engine room, resulting in a 23-degree upward angle. The temperature within the boat rises to 70° F. Eventually the submarine is pushed to the depth of 360 ft (110 m). The explosions loosen the fastenings for the supply drums which float to the surface. LtCdr Shimizu orders the remaining drums released from inside of the sub and some rubbish and oil ejected through a torpedo tube. All machinery is shut down. For the next four hours the submarine hovers at 360 ft, using the automatic trim system.

After surfacing ten hours after the start of the attack, the crew discovers one of I-165’s aft diving planes has been lost and the vertical rudder control shaft is bent. The entire aft section has been heavily washboarded by the explosions. [4]

23 August 1944:
The battered I-165 arrives at Ambon, Netherlands East Indies in the Banda Sea for temporary repairs.

27 August 1944:
Arrives at Surabaya.

10 September 1944:
Departs Surabaya for Singapore.

13 September 1944:
American codebreakers intercept an IJN mesage that reads: "I-165 was depth charged off Biak. Inspection in drydock reveals ----- extensive repairs required beyond local facilities. Major overhaul in Empire recommended (four months estimated)."

24 September 1944:
I-165 departs Singapore via Hainan Island for overhaul at Sasebo.

10 October 1944:
LtCdr Ono Yasushi (65)(former CO of RO-64) assumes command from LtCdr Shimizu.

17 October 1944:
Arrives at Sasebo.

15 December 1944:
Removed from active service and reassigned to the Kure SubRon's SubDiv 19 as a training ship.

1 April 1945:
Reassigned to SubDiv 34, Sixth Fleet. I-165's deck gun is removed and she is configured to carry two "kaiten" human torpedoes. She is also fitted with a Type 13 air search radar. After conversion she is returned to active duty in the Combined Fleet.

15 June 1945: The Eighth Kaiten Mission:
I-165 is in the "Todoroki" (sound of great cannon) group with I-36, I-361 and I-363. As the last boat of the group, I-165 departs the Hikari Kaiten base for a remote area E of Saipan to attack the American fleet.

16 June 1945:
At 1600, I-165, carrying 1-man "kaiten" suicide torpedoes, leaves the Bungo Channel at 1600 on 16th June and proceeds on a 35-day patrol to the east of the Mariannas to attack Allied shipping routes.

Off Bungo Suido. In heavy seas and murky weather, LtCdr Stephen S. Mann Jr.'s USS DEVILFISH (SS-292) on her third patrol sights the outgoing I-165 and fires two torpedoes from stern tubes. Ono evades the attack and crash-dives. DEVILFISH attempts to chase the adversary on the surface, but fails to regain the contact. Later, Ono later sends a situation report (the last one received from I-165).

23 June 1945:
Minelayer USS CHAMPION (AM-314)in concert with destroyer escort USS GILLIGAN (DE-508) detects an underwater contact (probably I-165) at 14-51N, 135-50E. The ships make several depth charge runs and hedgehog attacks which produce large air bubbles and diesel fuel. The contact is heard descending through 300ft after the last attack.

27 June 1945:
480 miles E of Saipan. At 1220, Lt (j.g.) R.C. Janes' Lockheed PV-2 "Harpoon" of VPB-142 is passing over a rain cloud when he makes a visual contact with a surfaced submarine heading NW at 14 knots, with what appears to be midget subs on its deck. Janes makes a sharp turn, swoops down and drops three Mark-47 depth charges and five markers. An oil slick is sighted, followed by fragments of wood and two kaitens.

At 1247, Janes drops a Mark-24 "Fido" acoustic homing torpedo, continuing the search until 1425. I-165 is lost at 15-28N, 153-39E with all 106 crewmen.[5]

28 June 1945:
Proceeding from Allied radio traffic analysis the IJN Owada Communications Unit reports that a Japanese submarine later identified as I-165 made a successful kaiten attack off Saipan.

29 July 1945:
Presumed lost in the Marianas.

15 September 1945:
Removed from the Navy List.


Authors' Notes:

[1] An I-165 machinist’s mate came down with acute appendicitis and underwent a successful surgery aboard the submarine.

[2] Older sources identify I-65’s victim as Dutch KPM merchant MEROENDOENG (2,464 tons), but she was even not at sea at the time of attack.

[3] Several sources claim that NANCY MOLLER’s master James B. Hansen was killed either in the torpedo explosion or during the machine-gunning of the survivors. In reality, he survived the attack. Able Seaman D. Fryer likewise survived the war.

[4] Several sources identify the IJN submarine damaged off Biak as I-365, but this is obviously a typo.

[5] A postwar Japanese analysis suggests that at the time of sighting I-165 could have been in the process of dumping her kaitens, which may have developed defects enroute to her target area.

[6] This report is the reason why some postwar accounts suggest that I-165 conducted a kaiten attack prior to her loss.
