The rescue effort is covered by destroyer HATSUZUKI. HATSUZUKI radios Ozawa that an American cruiser-destroyer force is attacking the destroyers left behind to assist CHIYODA. Ozawa orders OYODO, Rear Admiral Matsuda's CarDiv 4 and their destroyers to engage the Americans. They reverse course to 185 degrees, and set off at 16 knots. The Americans sink HATSUZUKI and chase off WAKATSUKI and KUWA, then sink stationary CHIYODA with all hands.

Holtz closes the range to attack. Reaching an attack position, he submerges to radar depth ahead of Kimura's force. BAYA has problems maintaining depth control, so Holtz decides to carry out his attack by sound. At 2207, at 3,200 yards, he fires a full bow salvo at the leading "cruiser" (actually ASASHIMO), but all six torpedoes miss.

24 July 1945: The Final Destruction of the Imperial Japanese Navy:
Etajima. From 0600 to 1700, OYODO suffers several attacks by about 50 of Vice Admiral (later Admiral) John S. McCain's Task Force 38's SB2C Helldiver dive-bombers and F6F Hellcats. She is strafed and hit by five 500-lb bombs and many near misses that cause her to list slightly to starboard. A major fire breaks out.

28 July 1945:
Etajima. From 0600 to 1700, OYODO suffers several attacks by about 40 of Task Force 38's aircraft. She is hit by four more bombs from SB2C-4s of USS WASP's (CV-18) Air Group 86 and by aircraft from SHANGRI-LA (CV-38) and F6F-5 fighter-bombers from MONTEREY's (CVL-26) VF-34. At 1000, hits near the bridge cause extensive flooding and OYODO takes on a heavy list to starboard. Captain Taguchi orders to counterflood the portside spaces to right his cruiser, but at 1200 she capsizes to starboard in shallow water. Soon thereafter the survivors abandon the ship. A total of 223 sailors are killed and 180 injured in the last two attacks.

In the afternoon the exposed hull of the cruiser is hit by 5-inch rockets, ripping two 2-ft wide holes in the portside hull.

20 November 1945:
Removed from the Navy List.

Authors' Notes:
[1] As per "Senshi Sosho", Vol. 96 (1976). Lacroix and Wells (1997, p. 647) provide slightly different data.

[2] Captain Taguchi's first name appears as Shoichi in older sources. The IJN Navy List of 1927 (p. 209), however, identifies him as Taguchi Masaichi.

Special thanks for assistance in researching the IJN officers mentioned in this TROM go to Mr. Jean-François Masson of Canada and Fontessa-san of Japan. Thanks for assistance also goes to "Adm. Gurita" of the Netherlands and Andrew Obluski of Poland. Special thanks go to Hans Mcilveen of the Netherlands for info on FRUMEL intercepts and to Erich Muehlthaler of Germany.
