Commander’s Comments:

After arriving in the designated patrol area we started patrolling north of island of Java. On 09 December we spotted a large patrol and changed course to avoid detection.

10 December 20:48 hours, radar contact at 9,000 yards off the port bow, a large contact according to the RTO. At 3,500 yards we dove to radar depth to avoid being sighted by any escorts, as the speed of this contact seems to indicate that this is a Battle Group of some kind. At 20:57 hours we spotted a CV coming out of the darkness and set-up and fired six torpedoes resulting in 5 hits and 1 dud with the subsequent sinking of a Shokaku Class CV. We also spotted a CA of an unknown class but could not get the stern tubes to bear before the escorts drove us deep. 22:43 hour’s soundman reports that there is "Low Speed screw sounds" overhead. The escorts’ pinging is very faint so we decided to go to periscope depth for a look-see. At 67 feet we spotted a CA circling our position and at 600 yards we fired 4 torpedoes at the CA resulting in 3 hits and 1 dud. Observed that the CA is now on fire and listing badly. Fired another torpedo resulting in the sinking of a Takao Class CA. Went deep to avoid the payback from the escorts again. Minor depth charging on the way to a save depth with only minor damage to the hull. After two hours we were able to evade and loose the ASW and resumed our patrol.

11 December, 19:42 hours, radar contact astern coming almost straight for us. We dove to avoid detection by any escorts. 19:53 hours we spotted a CVL Sea Plane carrier of the Chitose class. 19:58 hours we fired all stern tubes at the CVL resulting in 3 hits and 1 dud and sinking the target. We had to dive deep to avoid the ASW from the escorts. After about three hour’s time we were able to evade the ASW and finally resumed our patrol.

12 December, 05:20 hours, Radar contact and it’s very foggy out so we will try to move in under the cover of the fog seeing with the radar only. We were able to maneuver into the front of the contact using radar and went to radar depth with the target at 3,000 yards distance. 05:39 hours we spotted a medium convoy, and finally at 05:46 hours we fired at a and sunk a Troop Transport. Dove to avoid the ASW attack. Lost contact with the escorts and resumed patrol.

12 December, 20:02 hours, Radar contact, turned to intercept. 20:10 hours spotted a small convoy and after moving into firing position we fired two torpedoes resulting in 1 hit and 1 dud and sinking a Oil Tanker. Moved off with out ever being detected by the escort.

13 December, 00:09 hours, single radar contact. Moved into a firing position and after observing that the contact is a Standard Merchantman we decided to attack with the Deck gun. After chasing down the target we sank it with gunfire. Resuming patrol.

14 December, 11:23 hours, large radar contact. Executed an end-round to get into a firing position. 13:01 hours we are submerged in front of the on coming convoy. 13:16 hours fired and sank a Standard Merchantman, a Troop Transport and a Oil Tanker. We went deep to avoid the counter attack by the escorts and after 4 hours we were able to evade with no damage. Heading home with all tubes empty.

Captains note; The new Radar unit recently installed provided us with targets that we would normally would have missed.
