(All times are zone K, -10)
0727 hours - In position 27°55'N, 146°05'E sighted mast bearing 151°(T), estimated range 22000 yards. Commenced approach.

0735 hours - Identified the ship as a destroyer.

0740 hours - Sighted two escort carriers in column. The destroyer was patrolling approximately 2000 yards ahead of the leading carrier. Indended to attack the leading escort carrier but maneuvers to evade the destroyer made this impossible so settled for an attack on the second carrier instead.

0801 hours - In position 27°57'N, 146°07'E fired six bow torpedoes from 1000 yards. Two torpedo explosions were heard. At the time of the explosions the destroyer was being observed and the explosions were not observed. Commenced maneuvering to bring the stern tubes to bear.

0803 hours - Sound picked up fast screws close aboard. A very loud explosion then followed that shook the boat considerably. Thought this to be a second escort that had not been observed or it was a bomb dropped by an aircraft. Went deep and rigged for silent running.

0806 hours - At 375 feet. Proceeded to the south-west at slow speed.

0813 hours - Three depth charges were dropped.

1324 hours - Sighted an escort carrier bearing 036°(T) at a range of about 16000 yards in the approximate position of the attack. She was stopped and down by the stern.

1330 hours - Commenced approach. Sighted a seaplane patrolling near the carrier.

1400 hours - Sighted the plane coming towards. Went deep.

1420 hours - On the way back to periscope depth. Heard the destroyer coming towards. Went deep again.

1500 hours - Decided the destroyer was not in contact so started to proceed to periscope depth again.

1535 hours - Reached periscope depth. Sighted the other escort carrier towing the damaged one. The destroyer was patrolling between them and us. Range to the carriers was 14000 yards, speed 5 knots. Commenced approach. Soon lost the carriers in a rain squall and did not sight them afterwards.

1840 hours - Surfaced and conducted a radar search but unable to contact the carriers. Abondoned the search shortly before midnight and continued passage to our patrol area.
