Indian Ocean. SW of the Cocos Islands. HOKOKU MARU attacks Captain Willem Horsman's 6, 341-ton Royal Dutch Shell tanker ONDINA and her escort, LtCdr William J. Wilson's, RINR, Australian-built minesweeper HMIS BENGAL at 19-45S, 92-40E. BENGAL closes the range with HOKOKU MARU to protect the tanker.

At 1545 (JST), HOKOKU MARU opens fire. Both ships are damaged in the ensuing action. AIKOKU MARU is 6 miles NW of the scene and closing. A lucky shot from ONDINA's 4-inch gun hits HOKOKU MARU's starboard torpedo tube which had just been loaded. After the ensuing explosion, a fire breaks out that rages out of control and reaches the aft magazine. More explosions follow that blow out her sides. At 1752, HOKOKU MARU sinks. [4]

AIKOKU MARU arrives and hits BENGAL. LtCdr Wilson, confident the ONDINA can outrun the AMC, disengages at best possible speed. AIKOKU MARU scores six hits on ONDINA and virtually disables her. Captain Horsman is killed. AIKOKU MARU fires two torpedoes at the tanker, but both miss. With her ammunition expended, ONDINA's crew Abandons Ship.

AIKOKU MARU rescues 278 of HOKOKU MARU’s crew. She fires a last torpedo at ONDINA and departs. Later, AIKOKU MARU departs the Indian Ocean for Penang, then proceeds via Singapore to Rabaul.

18 November 1942:
ONDINA arrives at Fremantle.

Authors’ Notes:
[1] Japanese sources claim MALAMA was also torpedoed.

[2] On 20 July 1942, GENOTA is commissioned in the IJN as the oiler "OSE".

[3] This story was given first hand to Peter Cundall by HAURAKI's 3rd Engineer. HAURAKI is sent back to Japan, renamed HOKI MARU, and enters IJN service as a transport serving in the South Seas. HOKI MARU is sunk in Truk in Feb '44.

[4] Dutch and Japanese accounts of the battle are generally consistent, but the BENGAL's account does not match either one. Uncertainty also exists as to which ship scored the fatal hit on HOKOKU MARU. Dutch and Japanese sources credit ONDINA. In Singapore Naval circles, there were strong rumours that HOKOKU MARU was accidentally sunk by a hit from AIKOKU MARU.

Special thanks for assistance in developing this TROM go to go to Mssrs. Peter Cundall of Australia, Jean-Francois Masson of Canada, Andrew Obluski of Poland and Jan Visser of the Netherlands.

Thanks go to Toda Gengoro of Japan for information in Revision 4.
