Luzon Strait. At 1415, Cdr (later Captain) Gordon W. Underwood’s (USNA ’32) 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’s captain beaches her at Pasaquin Bay, N Luzon.
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. She moves off to deeper water and drops anchor. After many hours of stalking YUNAGI, SPADEFISH fires four stern torpedoes at YUNAGI, but the destroyer jinks at the last moment and they all miss. After surviving a counter attack, Underwood withdraws.
NIYO MARU is ordered to proceed with ASAKAZE to Manila while YUNAGI
remains to assist and protect the beached cripple.

The torpedo blows the bow off ASAKAZE, but she remains afloat and NIYO MARU takes her in tow for Dasol Bay. Nimitz, out of torpedoes, withdraws. As the destroyer's flooding increases dangerously, her crew abandons ship and is taken aboard NIYO MARU. 20 miles SW of Cape Bolinao, ASAKAZE rolls over and sinks at 16-06 N, 119-44 E. NIYO MARU proceeds safely into Dasol Bay.
