22 August 1944:
Luzon Strait. At 1415, Cdr (later Captain) Gordon W. Underwood’s USS SPADEFISH (SS-411) torpedoes HAKKO MARU No. 2 at 18-48N, 120-46E. Hit amidships and under the bow, she begins to flood. The escorts counterattack dropping 11 depth charges, but fail to damage SPADEFISH. Still able to make four knots, HAKKO MARU No. 2 is beached at PasaquinBay, N Luzon.
Destroyer YUNAGI patrols the bay. Underwood’s USS SPADEFISH makes several attempts to penetrate the bay and finsh off HAKKO MARU No. 2, but is foiled by YUNAGI. Meanwhile, the Japanese manage to refloat HAKKO MARU No. 2, move off to deeper water and drop anchor. After many hours of stalking the destroyer,
SPADEFISH fires four wakeless Mark-18 electric torpedoes from her stern tubes at YUNAGI, but the destroyer
jinks at the last moment and they all miss. After surviving a counter attack, Underwood withdraws.
25 August 1944:
GENKAI MARU and CD-25 are detached from passing convoy TAMA-24 and arrive at Pasaquin Bay. They offload five motor torpedo boats from HAKKO MARU No. 2 to GENKAI MARU. About 300 passengers are also transferred to several small motor-sail boats and taken to Manila. Later, YUNAGI is detached and joins convoy TAMA-24.
18 September 1944:
Pasaquin Bay. Efforts to salvage HAKKO MARU No. 2 fail. She breaks up in heavy swells and is later deemed a constructive total loss.
