Fluckey's (USNA ’35) USS BARB (SS-220) at the overlapping targets. AZUSA MARU blows up and sinks with all hands (100 crewmen and passengers). UNYO is hit starboard side by the other three torpedoes in Fluckey's salvo; one in the stern in the steering compartment, the other in the engine room. UNYO settles aft.

17 September 1944:
At 0142 UNYO radioes "Torpedo attack, two torpedoes, damage sustained." Sinking was not expected. However, the sea conditions worsened, pounding hard at the fantail, and collapsing the emergency reinforcements to the bulkheads. By 0730, UNYO is listing heavily to starboard, and the order is given to abandon ship. At 0755, she sinks by the stern at 19-10N, 116-35E.

Kaibokan CD-21 rescues her survivors and searches for the attacking submarine. At 1547, Cdr (later Rear Admiral) Charles W. Wilkins' (USNA ’24)USS SEAHORSE (SS-304) dives and begins an approach on the frigate from 16,900 yards. At 1757, Wilkins, now at 700 yards, fires a full bow spread of six torpedoes. One hits CD-21 that breaks in half and takes down 170 men including all survivors of AKANE MARU.

7 October 1944:
W of Manila. A wolf pack known as the “Holtz Cats”, consisting of LtCdr (later Captain) Arnold H. Holtz’s (USNA ’31) USS BAYA (SS-318), LtCdr Henry D. Sturr’s (USNA ’33) USS BECUNA and LtCdr Francis W. Scanland, Jr’s (USNA ’34) USS HAWKBILL (SS-366) heads through the South China Sea towards Fremantle, Australia.

USS BAYA intercepts a contact report from USS WHALE (SS-239) further north that a convoy escorted by two aircraft carriers and destroyers traveling at 14 knots is heading through USS BAYA's patrol area. Cdr Holtz alerts the USS HAWKBILL and USS BECUNA.

At 1900, USS BECUNA makes radar contact with the northbound convoy. A few minutes later, Scanland’s HAWKBILL sights the convoy. At 2149, USS HAWKBILL fires six torpedoes at a large freighter, but they all miss. Scanland then evades an escort.

Soon after attack on convoy HI-77 begins, MANJU MARU charges a submarine and drops depth charges, an act of bravery the convoy commander later cites.

At 2200, KINUGASA MARU carrying 1,000 port service workers, is hit by one or more torpedoes by either USS BAYA or USS HAWKBILL. Abandon Ship is ordered soon thereafter. MANJU MARU drops depth charges to prevent further attack.[1]

At 2224, USS HAWKBILL, running on the surface, attacks the same large freighter. Scanland fires three more torpedoes. This time two hit and cause a huge explosion. KINUGASA MARU was loaded with ammunition. The entire area is bathed in light. A mushroom of white and yellow flame rises hundreds of feet in the air. [2]

Holtz’s USS BAYA also fires torpedoes at KINUGASA MARU and claims two hits. [3]

At 2227, KINUGASA MARU sinks at 14-30 N, 115-446E. Ten passengers and 33 crewmen are killed.

Haylor's (USNA ’36) USS HAKE (SS-256) and LtCdr (later Cdr) Francis A. Greenup's (USNA ’36) USS HARDHEAD (SS-365).

6 January 1945:
Gulf of Thailand, 60 miles NE of Kota Bharu, Malaya. LtCdr (later Cdr) Thomas L. Wogan’s (USNA ’30) USS BESUGO (SS-321), patrolling the mouth of the Gulf, picks up a target on SJ radar.

10 March 1945:
Removed from the Navy List.

Authors' Note:
[1] The time of the torpedoing of KINUGASA MARU is based on Japanese records and varies from American records; however, the early abandonment of the ship better explains the low number of lives lost.

[2] Most sources, including Japanese sources, credit USS HAWKBILL and USS BAYA with sinking KINUGASA MARU W of Balintang Channel, NNW of Luzon at 19-40N, 118-05E.

[3] USS BAYA claimed two hits at 2233 - six minutes after USS HAWKBILL reported KINUGASA MARU sank.
