Kobe. Undergoes hull inspection at Pier No. 1 of Mitsubishi Heavy Industries, Ltd. shipyard. ASAHI MARU enters drydock.

At 1700, Rear Admiral (later Vice Admiral) Hirose Sueto's (39) Balikpapan Invasion Convoy departs Tarakan, Borneo with IJN transports NITTEI, ASAHISAN, TATSUGAMI, NANA, KANAYAMASAN, SUMANOURA, KUMAGAWA and TOEI MARUs and IJA transports KURETAKE, HAVANA, EHIME, LIVERPOOL, TEIRYU (ex-German AUGSBURG), HITERU, TSURUGA, HANKOW and NISSHO MARUs carrying the Balikpapan Invasion Force consisting of MajGen Sakaguchi Shizuo’s 56th Mixed Infantry Group (Sakaguchi Detachment) and the Kure No. 2 Special Naval Landing Force (SNLF) escorted by patrol boats PB-36, PB-37, PB-38, minesweepers W-15, W-16, W-17, W-18 and SubChasDiv 31's CH-10, CH-11 and CH-12.
Cover is provided by light cruiser NAKA with DesDiv 2's YUDACHI, SAMIDARE, MURASAME, HARUSAME, DesDiv 9's ASAGUMO, MINEGUMO, NATSUGUMO and DesDiv 24's KAWAKAZE and UMIKAZE. Seaplane tenders SANUKI and SANYO MARUs provide air cover.
Poor weather hampers air reconnaissance by ABDA (American-British-Dutch-Australian) forces, but ABDA Air finally locates the invasion force. Rear Admiral (later Vice Admiral) William A. Glassford's Task Force 5's light cruisers USS MARBLEHEAD (CL-12), BOISE (CL-47) and Cdr Paul H. Talbot's DesDiv 59's old destroyers PARROTT (DD-218), POPE (DD-225), JOHN D. FORD (DD-228) and PAUL JONES (DD-230) are ordered by Admiral (later Senator) Thomas C. Hart (USNA 97), ADBAFLOAT  Commander, to intercept the convoy before it reaches Balikpapan.
22 January 1942:
Davao. Provisioned by transport KIRISHIMA MARU.
23 January 1942: The Invasion of Balikpapan, Dutch Borneo:
Davao. Provisioned by minelayer NICHIYU MARU.
Glassford heads north to find the IJN invasion force, but USS BOISE runs aground on a reef and is forced to retire and USS MARBLEHEAD develops engine trouble. DesDiv 59 is detached and increases speed so as to arrive at Balikpapan at midnight.
Storms protect the invasion force until it is almost to Balikpapan. At 1050, the convoy is attacked by three enemy aircraft, which are repulsed. At 1525, nine Dutch Martin Model 166 (B-10) bombers and four light bombers from Samarinda attack and hit transports NANA and TATSUGAMI MARUs. The latter is hit in No. 6 hold by a bomb, splinters from others that land to port alongside the same hold add to the fires raised. Navigation became impossible and over the following hours the flames take a firm grip. At 1730, the ‘Abandon Ship’ order is given. Finally, at 2100, after a huge explosion the ship sinks at 01-18S, 117-43E with unknown casualties. TATSUGAMI MARU, only slightly damaged, continues to Balikpapan. At 2130, the transports begin disembarking their troops.
24 January 1942:
Dutch Navy LtCdr C. A. J. van Well Groeneveld's (former CO of HMNS K-XIV) submarine HMNS K-XVIII, operating on the surface due to the weather, fires four bow torpedoes at the light cruiser NAKA, flagship of the IJN's covering force, but they all miss. At 0045, Groeneveld fires at NAKA, but misses and hits transport TSURUGA MARU port amidships, sinking her with the loss of one crewman and 38 troops. The covering force moves eastwards to carry out antisubmarine sweeps.
Cdr Talbot's DesDiv 59 arrives from the south. Since the covering force is to the east searching for submarines, the four destroyers are virtually unopposed. At 0316, they begin their first attack firing their 4-inch guns and launching ten torpedoes at the anchored transports, but all their torpedoes miss. Talbot orders another attack.
At 0330, the USS POPE hits and sinks transport SUMANOURA MARU. Only nine of her crew of navy sailors survive. At 0335, USS PARROTT and the USS PAUL JONES hit transport TATSUGAMI MARU with torpedoes in a deep fuel tank, the resultant flooding cause her to sink by the stern in Balikpapan Bay at 01-18 S, 117-04E, and four of her crew lose their lives. USS POPE and USS PARROTT sink the 2nd Base Force's patrol boat PB-37 (casualties unknown) with torpedoes and gunfire.
At 0345, USS JOHN D. FORD sinks transport KURETAKE MARU with gunfire and torpedoes. Six crewmen and 272 troops are KIA. ASAHISAN MARU suffers damage from gunfire and torpedoes but remains afloat. KUMAGAWA MARU also suffers slight damage in the engagement. At 0332, USS JOHN D. FORD scores gunfire hits on ASAHI MARU whose hospital ship status is obscured by the darkness. At 0350, their torpedoes gone, Talbot's DesDiv 59 departs southward.

 ABDAFLOAT = American, British, Dutch and Australian Naval Command. In reality, a non-unified command.
 This marks the first known instance of an Allied attack on a Japanese hospital ship during the Pacific War.
 This IJN shared 5,794-ton collier (B/C-AC) YASUKUNI MARU was not IJN Sub Tender YASUKUNI MARU.
 The absence of damage to the larger ships in the convoy suggests they may have detached for Kirun (Keelung) before the attack with only the slower escorts and cripples left behind.
Thanks to Mr. John Whitman of Virginia, USA, Mr. Matt Jones of USA and Mr. Gilbert Casse of France.
