1112 I/9 Sighted two seaplanes through periscope, may have been PBM's.
1135 I/9 Surfaced.
1624 I/9 Sighted two planes, submerged.
1911 I/9 Surfaced to run through TOKARA GUNTO.
2011 I/9 APR contact 132 Meg., sweeping across us every 3 seconds.
2020 I/9 Plane turned on searchlight, too late to drop. Submerged.
2229 I/9 Surfaced.
2235 I/9 Plane diving at us, submerged. Changed course to east to clear cut.
They have us cut in. Will try another approach on the surface

0724 I/10 Surfaced for another try at transiting TOKARA GUNTO.
0854 I/10 Sighted plane. Submerged.
1410 I/10 Surfaced for another attempt at getting into the East China Sea.
With a force 4-5 wind and number 3 sea, the aircraft left us alone.
11 April 1945
0400 I/11 J.O.O.D. sighted a persistent white cap and got us turned away in
time to watch two torpedo tracks run parallel to our new course. A
beautiful shot; 120' degree track down the trough of the sea. The
SD and SJ had been secured to prevent planes homing, and the ST
failed to pick up land at 20,000 yards, a surfaced submarine at
about 1500 yards, and planes right on top of us. There must be
an answer, but so far we haven't found it. Turned on SJ to search
for our assailant and found nothing. Spent the day submerged to
rest and devise some aircraft evasion tactics.
2215 I/11 Driven down by a plane at 6 miles. Picked up this one on AFR-1
and keyed the SD.
12 April 1945
1200 I/12 L 30-38N
l 128-37 E
0100 I/12 Surfaced for another short run.
0340 I/12 Another plane ran us down, made contact by same means as before;
APR-1 and then keyed the SD.
0507 I/12 Surfaced to try our "best speed" again.
0517 I/12 Just got our blowers stopped - submerged for a plane sighted.
0616 I/12 Surfaced.
0621 I/12 Did not get the blowers secured this time - another plane.
1015 I/12 Surfaced to get on with the war.
1017 I/12 Hardly got the blowers started. Submerged for two planes headed
our way.
1054 I/12 Surfaced.
1119 I/12 Another plane - submerged.
1225 I/12 Sighted through the periscope and had a good look at our tormentors.
They were two EMILYS in column, distance about 1000 yards, altitude
not more than 200 feet.
1518 I/12 Surfaced.
1647 I/12 Sighted a single EMILY. This one circled wide around toward the sun
and then turned our way. Submerged.
2002 I/12 Surfaced. Managed to stay up all night and actually made best speed.

13 April 1945
1200 I/13 Submerged patrol on line between SASEBO and SAISHU TO.
2145 I/13 Exchanged calls with TRUTTA by SJ radar. Changed our tactics. Now
swinging the SJ at high speed on the 20,000 yard scale to detect the
night fliers. The ST is not doing the job properly.
2330 I/13 Plane contact on SJ at 7 miles, closed to 3 miles. Submerged for one
hour.
14 April 1945
1200 I/14 Submerged patrol on SASEBO - SAISHU TO line.
0900 I/14 Heard echo ranging to eastward on 15.2 kcs. and 18.8 kcs. Headed for
pingers.
1030 I/14 Sighted smoke through the periscope. Started approach on what turned
out to be one 2000 ton freighter and three frigate-type escorts.
Shortest range to track was 5300 yards by ST radar. It was small
gratification to know the ST was working.
2000 I/14 Surfaced to get on the possible SHANGHAI route of our target. Made
maximum speed again.
15 April 1945
0208 I/15 Submerged for plane.
0323 I/15 Surfaced.
0350 I/15 Submerged for plane.
Conducting submerged patrol southwest of SAISHU TO on line to SHANGHAI.
Heard numerous depth charge explosions at random times, all distant.
2000 I/15 Surfaced to go to the northern part of YELLOW SEA. The sea was flat
calm. Started getting strong radar echoes to limit of sargeens all
around the compass. Most of them were in pairs.
2300 I/15 Turned south to investigate two targets which had moved in from
80,000 yards to 50,000 yards in about an hour. They had practically
stopped.
16 April 1945
0200 I/16 Interference very strong all around on the SJ. Keyed the SD and made
contact at 10 miles, closing. Submerged.
0300 I/16 Surfaced and found that our two targets had shifted to east of us.
The distance traveled would require a speed of over 15 knots.
0330 I/16 More strong interference on the SJ, all around. Submerged on an SD
contact at 6 miles. It looks as though our enemy is using a sugar
band airborne radar. The pulse rate synchronizes perfectly with ours
at about 1600 pulses/second.
0430 I/16 Surfaced for morning stars. The long range targets had all secured
for the day.
Conducted submerged patrol to SAISHU TO - SHANGHAI route. Sighted
3 mines.
2000 I/16 Surfaced and closed southwest corner of SAISHU TO. We were apparently
undetected by the radar on MARA TO at 20,000 yards.
17 April 1945
1200 I/17 Investigated KEITEITO BYOCHI submerged. Nothing sighted except a dozen
fishermen. Heard echo ranging from direction of land all day.
2000 I/17 Surfaced and headed for SAISHU KAIKYO. Sea flat-calm - chased more
gremlins without result.
18 April 1945
1200 I/18 As we headed west into SAISHU KAIKYU suspected that a shore-based radar on
the N.E. point of SAISHU TO was tracking us.
0400 I/18 Received orders from TRUTTA to join her in north part of YELLOW SEA. Too late
to back out of here today.
0630 I/18 Suspicions confirmed. A small patrol boat came south from the Korean coast
and started an alternative pinging and listening search at the position of our
dive. Went deep (150 feet) as he approached too close for periscope observations.
0730 I/18 Another patrol came out from SAISHU TO.
0830 I/18 A third patrol started pinging to the east of us. These three echo-ranged and
listened until about sunset, occasionally working over a false contact with a
healthy barrage of depth charges.
LIONFISH retired to eastward.
2030 I/18 Surfaced and started the long trek to join TRUTTA. Rainstorms and growing seas
aided our retirement. The Japs passed up a good chance to really bottle up an
American submarine. A few radar pickets would have done the trick.

19 April 1945
0130 I/19 Made a contact at 10,000 yards on an SJ equipped submarine. Turned to avoid
and made a contact at 4000 yards on a single unidentified target. Left those
two to figure it out for themselves, we had a long trip ahead.
20 April 1945
1200 I/20 Enroute new station on west coast of KOREA.
21 April 1945
0330 I/21 Received aircraft contact report on battleship and carrier standing north
along China Coast, and cruiser heading for SAISHU TO from SHANGHAI. Started
patrol west of NOKUZAK TO on the long chance that the BB and CV were going
to cross the YELLOW SEA during the day.
22 April 1945
0600 I/22 Submerged patrol west of KOKUZAN TO.
(Ship Contact No. 5) Sighted and heard echo ranging of frigate-type patrol
headed west from KOKUZAN TO, passed 6000 yards to South.
23 April 1945 - 27 April 1945
Fog-bound patrol off SEKINO SUIDO, DAITO WAN, and SHANTUNG PROMONTORY.
1200 I/27 During this period the sea was dead calm. Visibility varied zero to two
miles during the day, and from zero to unlimited at night. Radar performance
was phenomenal, with "gremlins" moving all over the screen at ranges up
to 90,000 yards. Encountered many small boats at night, and sighted or
heard a few off the western approaches to DAITO WAN and SEKINO SUIDO.
28 April 1945
0100 I/28 Radar contact at 37,000 yards on a gremlin which tracked for a change;
course 120, speed 4~5. Closed to 6000 yards in a bright full moon and
could see nothing. Submerged on the track. Suspected a small A/S vessel
sending up radar decoys. The target tracked perfectly on the ST. No sound
contact. At a range of 3000 yards sighted a sailing junk. Let him go by
for a look in daylight in preparation for a work-out on the deck gun. Made
an end-around and had a good look. No one could tell whether the characters
painted on the stern were Chinese or Jap, but he was not powered, not loaded,
and not armed. Let him go. Maximum radar range on this target by daylight
was 8000 yards.
29 April 1945
1100 I/29 Submerged patrol on south coast of KWANTUNG PENINSULA.
Visibility reduced to 100 yards by fog. Found the ST radar excellent for in-
shore navigation.
We had planned on stirring up a little excitement by lobbing about 50 rounds
of 5' H.E. into the port area of PORT ARTHUR. Object: confusion, more than
damage, but the fog persisted until midnight. Headed for southern part of area
12 as ordered by SPRINGER. Ran through the entire China Coast fishing fleet
north of SHANTUNG PROVINCE, 8000 yard radar contacts all around the dial for
three hours.
30 April 1945

l 124-18 E
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Submerged patrol on TSINGTAO-DAITO WAN route, southwest of DAITO WAN west entrance.
0900 I/30 Two echo-rangers made a sweep headed southwest. Visibility about one mile.
Heard several heavy barrages of depth charges, very distant.
1530 I/30 Heard five or six pings to northwest. Changed to optimum approach course for anyone
headed for DAITO WAN. Depth charging still going on, but less frequently.
1 May 1945
1230 I/1 Enroute southern part of Area 12.
Destroyed by gunfire a three-masted schooner of about 100 tons. It was loaded with
lumber and logs. Fires were burning merrily when we shoved off.
1825 I/1 Sighted small PC type patrol standing west from vicinity of DAI KOKUZAN. Avoided
on the surface.
2 May 1945
1200 I/2 Submerged patrol southwest of SAISHU TO.
3 May 1945
1200 I/3 Submerged patrol east of SADDLE IS.
4 May 1945
1200 I/4 Patrol east of SADDLE IS. Life guarding for SHANGHAI strikes. More phenomenal radar
ranges. Small fishing boats showed as large targets at 37,000 yards.
2340 I/4 Submerged for plane closing rapidly. APR contact at 180 megacycles.
5 May 1945
1200 I/5 Patrol and life guard east of SADDLE IS.
0158 I/5 Submerged when plane illuminated us with searchlight.
0303 I/5 Submerged again for rapidly closing plane, APR contact at 180 megacycles.
0408 I/5 Surfaced and shortly thereafter sighted and made contact on a large ship
with running lights and a brightly illuminated red cross amidships. When
contact was first established he tracked at zero speed. Shortly thereafter
he increased to 16 knots on course 010 degrees T. Did not consider the
speed change suspicious, and let him go by as a properly marked hospital
ship.
1945 I/5 Sighted TREPANG through periscope and surfaced. He relieved us of life
guard duty. Headed for home.
6 May 1945
1200 I/6 Enroute SAIPAN from SHANGHAI. Sea glassy, radar ranges phenomenal. Made radar
contact at 38,000 yards on a small power boat, which was barely visible on a
clear night at 2000 yards.
0645 I/6 Sighted plane which looked like a PBM. Angle on the bow was zero at four miles,
however, Submerged.
1345 I/6 Sighted plane as before. Submerged. We would certainly like to know if these
planes are friendly, but they give us no chance to find out safely.
1500 I/6 Surfaced.
1619 I/6 Ship Contact No. 14. Sighted small freighter through the high periscope. It was
apparently headed for SHANGHAI from NAGASAKI or SASEBO, and without escort.
Made an end-around and arrived on the track with a range about 20,000 as the
sunset haze set in. There was a sharp horizon behind us, none on his bearing.
1840 I/6 With generated range about 10,000 and no radar contact decided he had sighted us.
Started search at flank speed. This night, for the first time in several days,
radar ranges were normal.
Contact not regained.

7 May 1945
1200 I/7 Enroute SAIPAN.
0823 I/7 Sighted plane, closing fast, Submerged.
0943 I/7 Sighted plane, not closing.
1104 I/7 Sighted plane, closing, Submerged.
1500 I/7 Sighted plane, closing, Submerged.
All of the above planes looked like PBM's, except the one not closing, which may
have been a PRIVATEER. The PBM's were too close to ask questions, so we pulled the
plug and may have lost three chances to pick up a contact.
1605 I/7 Heard a block-buster, not aimed at us, but not too far away, either.
1640 I/7 Surfaced.
1820 I/7 Sighted TREPANG through high periscope. Exchanged calls by radar.
8 May 1945
1119 I/8 Sighted plane, closing, Submerged. This one looked like the others of the past few
days, a large 2-engined flying boat.
1900 I/8 Passed through NANSEI SHOTO and headed for rendezvous with RAY.
9 May 1945
1200 I/9 Waiting for the RAY to deliver her B-29 survivors and ECM. Fired on two floating
mines. Scored several 20mm and 40 mm hits without sinking or exploding either mine.
1915 I/9 Moored alongside U.S.S. RAY. Received 10 B-29 survivors (3 wounded) and the RAY's
ECM.
1939 I/9 Set course for SAIPAN.
2200 I/9 Converted ballast tanks.
2330 I/9 Reversed course to take life guard station off KYUSHU.
10 May 1945
0100 I/10 APR contact 180 megacycles.
0106 I/10 Rapidly closing SJ Radar contact on plane. Submerged.
0800 I/10 Arrived on station and relieved the RAY.
1315 I/10 No business for us. Headed for the barn once more.
1610 I/10 Sighted two more mines.
11 May 1945
0840 I/11 APR contact at 145 megacycles.
0848 I/11 Rapidly closing SJ radar contact in direction of a low cloud. Nothing sighted.
Submerged.
1130 I/11 Many SD contacts at ranges of 25-60 miles, probably B-29's.
1515 I/11 Sighted two mines. Horny-looking brutes.
12-15 May 1945
Enroute SAIPAN.
1200 K/15 Arrived alongside ORION (AS18). Disembarked aviators and refueled.
1000 K/16 Underway for Midway.
