Rear Admiral (Vice Admiral, posthumously) Kajioka Sadamichi (39) (former CO of KISO) of the 6th Escort Convoy is the convoy commander. The convoy's escorts are escort carrier TAIYO, destroyers FUJINAMI and YUNAGI, kaibokan HIRATO, KURAHASHI, MIKURA, SHONAN and CD-11. TAIYO's 631st Naval Air Group provides air cover with 12 Nakajima B5N Kates.

Because of the fire and speed of sinking, most of her crew are lost. If common practice obtained, including passengers about 1,200 were probably aboard. Of these reportedly 747 perish; but by some miracle, her CO, Captain Sugino Shuichi (46) is among the just over 400 surviving crew and passengers. At 2312, RASHER also torpedoes and hits TEIA MARU. The ex-French liner is set afire and explodes at 2340 at 10-09N, 119-56E. 2,665 passengers and crew are lost [3]

Author's Notes:
[1] Fuel oil was of four grades:
L0: Heavy oil for boilers.
L1: No. 1 heavy oil for diesel. 90% light oil ingredient.
L2: No. 2 heavy oil for diesel. 50% light oil ingredient.
L3: No. 3 heavy oil for boilers. Less than 10% light oil ingredient.

[2] Lubricating oil was of two grades:
No. 1 for internal lubrication of machinery (cylinders, etc.).
No. 2 for external lubrication of machinery.

Conversion: 1000 liters = 264.172 US gallons.

[3] Sources vary as to the number of passengers and crew aboard TEIA MARU. One Japanese source gives 5,478 passengers while another lists 4,795 Army (many air force) and 427 civilians. Of these, 2,316 troops, 275 passengers, 6 armed guards, 4 shipboard gunners, 10 special lookouts, and 54 crewmen, for a total of 2,665 were KIA. USN radio intercepts put passenger strength at 5,300.

[4] TAMATSU MARU was carrying the IJA’s 2nd Battalion and regimental headquarters of the 13th Independent Infantry Regiment (26th Division) and division and regiment communications troops. She also carried four of the twelve 100-mm guns of the 22nd Field Heavy Artillery Regiment and one of the four 300-mm howitzers of the 4th Independent Heavy Artillery Battalion. The 19th Independent Rapid Fire Artillery Battalion was aboard with about 480 men and twelve 47-mm antitank guns. Included were various headquarters and airfield units. One 179-man airfield management section was bound for the Philippines. The IJA’s 6th Aviation Signal Regiment was heading for Cebu.

The sinking of TAMATSU MARU was the worst merchant disaster of the Pacific War and the fourth worst loss of life on any Japanese vessel during the war.

[5] According to some sources TEIYO MARU was sunk by LtCdr Henderson's USS BLUEFISH.

Special thanks go to Yutaka Iwasaki of Japan for his generous help in decoding IJN fuel grades in JACAR. Thanks also go to John Whitman of the USA and Fontessa-san of Japan for JACAR data on the troops carried by TAMATSU and TEIYO MARUs and general thanks to Gilbert Casse of France.
