27 May 1945:
Korea Strait, off Geomundo Island. AGUNI and kaibokan OKINAWA are attacked by two Consolidated PB4Y-2B "Privateers" piloted by Lt Leo E. Kennedy and LtCdr (later Rear Admiral, USNR-Ret) George L. Hicks of Patrol Bombing Squadron VPB-109 based at Yontan, Okinawa.
Kennedy launches a Mark-9, Mod 0, Special Weapon Ordnance Device (SWOD) radar-guided “Bat” glide bomb from a long distance. The bomb's 1,000-lb warhead explodes off AGUNI’s starboard bow demolishing the whole foredeck area ahead of the bridge and killing 33 sailors. After being hit, AGUNI's crew have to cut her anchor chain to free her. Kaibokan CD-12 is dispatched to assist OKINAWA in rescuing AGUNI’s crew, but despite the heavy damage the kaibokan remains navigable and proceeds stern first to Pusan, Korea on her own power. 
Pusan. AGUNI undergoes repairs at Chosen Heavy Industries' shipyard until the end of war.

Pusan. AGUNI's crew is notified of the termination of the war.

Removed from the Navy List.
20 May 1948:
Scrapped at Iino Kaiun K. K's Yard (former Maizuru Navy Yard).
 The account of the “Bat” attack is based largely on Kimata Jiro’s 1994 Nippon Kaibokan Senshi ("Battle History of Japanese Kaibokan Frigates"). Contrary to some reports by USN personnel, the "destroyer" (sic) (AGUNI) did not sink. Other sources attribute AGUNI’s damage to a mine. In fact, the Japanese characters for "mine" and "guided bomb" can be confused, but the damage itself supports a bomb or missile attack since there was no underwater damage. Only the foredeck was dished in. Moreover, AGUNI's sailors identified the weapon as a "miniature aircraft".
In the same attack, using conventional bombs, Kennedy sank 882-ton 2E type freighter DAITO MARU No. 2 and four smaller freighters and damaged two small vessels. For this action Kennedy was awarded the Navy Cross, but he was KIA three days later by AA fire while making a conventional attack off the Yangtze River, China.
Thanks go to Dr. Higuchi Tatsuhiro of Japan. Thanks also go to Jeff Donahoo of Iowa and Matthre Jones of Ohio for help in identifying kaibokan COs and to Gilbert Casse of France.
