Combined Fleet - IJN Escort Aguni: Tabular Record of Movement
Patrol Bombing Squadron 109 (VPB-109) War Diary, May 1945, page 13
(Page 13) “[May 27, 1945] traveled true, hitting destroyer directly on the bow above water line. The explosion blew off the bow back to the turret. Both planes circled at 5,000 feet altitude at 6 to 7 miles distant before AA from the undamaged DD was received, forcing withdrawal. As soon as the AT detonated, the undamaged destroyer originally a mile away, proceeded to a position 100 yards from the sinking destroyer, then turned broadside to the planes (both destroyers had initially turned bow to the planes’ attack) to fire. Firing started as the last window settled to the water.”
