S-13 (SS-118) was laid down on 14 February 1920
by the Portsmouth (N.H.) Navy Yard; launched on 20
October 1921; sponsored by Miss Mary Howe; and
commissioned on 14 July 1923, Lt. Wilder D. Baker in
command.

Following duty along the northeast coast in 1923, S-
13 visited the Panama Canal Zone, St. Thomas, and
Trinidad from January into April 1924. Sailing from
New London on 24 November, she proceeded, via the
Panama Canal and California, visited Hawaii from 27
April to 25 May 1925, and returned to New London on
12 July. In addition to service in the northeast from
then through 1928, S-13 operated in the Panama Canal
area from February through April 1926; visited
Kingston, Jamaica, from 20 to 28 March 1927; and
served again in the Panama Canal area from February
into April 1928. From 1929 into 1936, S-13 operated
almost exclusively in the Panama Canal area, although
she visited Baltimore from 15 May to 5 June 1933, and
New London from 15 May to 1 June 1935. Departing
Coco Solo on 13 June 1936, S-13 was decommissioned
on 30 September that year at Philadelphia.

S-13 was recommissioned on 28 October 1940. Fol-
lowing voyages to Bermuda, S-13 operated in the Pan-
ama Canal area from December 1941 into June 1942;
off Guantanamo from June into August; in the Pan-
ama Canal area from August into January 1944; at
Trinidad from February into May; at Guantanamo
from May through July; and in the Panama Canal
area through the remainder of the year. Departing
Coco Solo on 3 January 1945, S-13 proceeded to Phila-
delphia for inactivation. She was decommissioned on 10
April 1945, struck from the Navy list on 19 May and
sold on 28 October of that year to Rosoff Bros., New
York City. Resold to Northern Metals Co., Philadel-
phia, Pa., on an unspecified date, she was scrapped.

2. In general the weather during the entire patrol was mostly
  favorable for conducting a surface patrol. About one half of
  the time, however, skies were overcast and intermittently there
  were numerous rain squalls and periods of greatly reduced
  visibility which did not continue for more than three or four
  hours at a time.
  Seas were from the southwest and south during the entire
  patrol and varied in intensity from condition 1 to 5. At no
  time were the seas rough enough to cause serious discomfort.
  Wind during the entire period was from the south and south-
  west and varied in force from 1 - 5.

3. Due to overcast skies, fixes were obtained only at irregular
   intervals. As a result the daily set and drift as shown by
   the fixes obtained indicated no constant tidal information.
   Although most sets were in an easterly direction the only
   description applicable to the currents based on the information
   obtained was that they were "various and unpredictable".

4. Routine.

5. None sighted until last day in Gulf of Panama. These vessels
   were not identified as they were escorted by patrol vessels.

6. Aircraft sighted as follows:

   1110 June 4,1942 - Lat 07° 16' N Long. 91° 45' W. Sighted
                     4 Motored Army bomber on easterly course.
                     Plane circled ship three times then
                     proceeded eastward.

   1115 June 4, 1942 - Sighted Navy patrol plane which passed
                     directly over-head and continued to
                     southwest.

   1101 June 6, 1942 - Lat. 07° 07' N Long. 91° 45' W. Sighted
                     4 motored Army bomber on northerly course.
                     Exchanged signals on searchlight and plane
                     continued to westward.

   1005 June 7, 1942 - Lat 07° 26' N Long. 91° 19' W. Sighted
                     4 motored Army bomber directly overhead.
                     Bomber circled, exchanged signals and
                     proceeded to westward.

   1047 June 8, 1942 - Lat. 07° 12' N Long. 91° 20' W. Sighted
                     PBY Navy plane 6 miles to eastward on a
                     northerly course. Plane did not approach
                     closer and probably did not sight this
                     vessel.

   1112 June 9, 1942 - Lat. 07° 21' N. Long. 92° 20' W. Sighted
                     Army bomber to the southwest, distance
                     9 miles on a westerly course.

   1120 June 9, 1942 - Sighted Navy PBY plane to the northeast,
                     distance 8 miles on a northwesterly course.
                     Neither plane appeared to sight this vessel
                     as neither approached to exchange recognition
                     signals and each proceeded on his original
                     course.

   0952 June 11, 1942 - Lat. 06° 08' N Long. 92° 07' W. Sighted
                     Navy PBY plane 8 miles on the port quarter
                     headed on a westerly course. Plane circled
                     submarine close aboard, exchanged signals
                     and departed to northward.

1255 June 11, 1942 - Lat. 06° 08' N Long. 92° 23' W. Sighted
                       Navy PBY plane 10 miles ahead on a southerly
                       course. Plane did not change course and
                       apparently did not sight this vessel.
0935 June 13, 1942 - Lat. 06° 04' N. Long. 92° 13' W. Sighted
                       Navy PBY plane 8 miles to northeast on
                       a westerly course. Plane evidently did not
                       sight this vessel.
1105 June 18, 1942 - Lat. 05° 50' N. Long. 92° 10' W. Sighted
                       Navy PBY plane 9 miles to eastward on a
                       northerly course. Plane evidently did not
                       sight this vessel.
June 20, 1942    - During passage in Panama Bay sighted 3
                       Army bombers and numerous P-40 fighter planes.

7. None.

9. None.

10. Radio reception was in general poor. Static was worst at night
    from midnight to about six in the morning. During this period
    although the signals from N.A.A. (Washington, D.C.) 15.6 k.c., was
    usually of strength 4, interference made it practically impossible
    to make accurate copies of their complete schedules broadcasted at
    that time. During daylight, particularly from about ten in the morn-
    ing until sunset, the signals from N.A.A faded out so that reception
    during this period was also unreliable. At periscope depth, N.A.A.
    on 15.6 k.c. could not be copied but N.A.A. on 18.0 k.c. frequently
    came in well enough to be reliable. At all times surface and sub-
    merged, N.A.A. came in better on 18.0 k.c. than on 15.6 k.c. From
    N.A.B., Balboa, C.Z., 24.0 k.c., the reception was usually good
    and when the new schedule was started on 19 June, 1942, it was
    received complete.
         Messages originating at N.B.C., Coco Solo, C.Z., (4155 k.c.)
    directed to submarines in the Pacific frontier were received with
    only slight garbles.
         Considerable difficulty was experienced in trying to get N.B.C.
    to answer up when called, the delay caused by this failure to
    establish radio communication amounting to one instance to three
    hours. If the message to be relayed had been a contact report it
    is doubtful if it could have gotten thru before this vessel would
    have been forced to submerge.

11. As no vessels were encountered while submerged there was no
    opportunity to test out sound conditions. However, temperature
    variations at various depths were noted indicating the probable
    presence of density layers.

12. Health of the entire crew was excellent throughout the patrol.
    There were one or two minor stomach disorders but these responded
    to treatment except in one case which from its case history is
    chronic. Being on the surface during most of the patrol permitted
    the ship to be adequately ventilated at all times and the living
    spaces were therefore comfortable. Had the seas been exceedingly
    rough, or had it been necessary to remain submerged for extended
    periods of time, conditions would undoubtedly have been much worse.

13. Engine miles steamed: Surface - 4093.5; Submerged - 45.4.

14. Fuel oil expended - 19,697 gallons.

15. Factors of endurance remaining:

16. Patrol was discontinued in accordance with operation order before
    any factor of endurance required it. However, since ship carried
    only two thirds of her capacity when actually leaving for patrol
    only 6895 gallons remained upon return to base. It is believed
    the limiting factors would have been provisions and fuel for this
    particular patrol.

17. No.remarks.

From: Commander Submarine Division Thirty-Two.
To : Commander Submarines, Atlantic Fleet.
Via : Commander Submarine Squadron Three.

SUBJECT: USS S-13 - Report of First War Patrol.

1. Forwarded. The patrol was uneventful, no contacts
with the enemy having been made.

2. The material condition of S-13 upon completion of
patrol was excellent, no serious casualties having been en-
countered. The Commanding Officer, S-13, is to be congratulated
upon the excellent state of cleanliness of his ship after 38
days at sea away from the Submarine Base. This condition, in
the opinion of the Division Commander, shows an exceptionally
high state of morale and pride in their ship on the part of the
officers and crew.

SUBJECT: USS S-13 - Report of First War Patrol.

1. Forwarded. The weather information submitted
conforms with previous reports. Density layers have frequently
been encountered in the locality.

2. Radio reception is frequently poor in this area
owing to atmospheric conditions. It is considered that use
of NBA primary broadcast on 24 kcs will overcome the difficulties
with NAA broadcasts. Radio San Juan, at approximately the same
distance from Coco Solo as the patrol station, causes considerable
interference on 4155 kcs and some on 8310. In asmuch as frequencies
above the limit of the TCE transmitters (9050 kcs) are not available
the only possible solution would seem to be the stationing of a
relay ship about half way to the patrol area. This is not
practicable as a permanent station.

SUBMARINE DIVISION THIRTY-TWO

c/o Postmaster, New York, New York
3 July 1942.

From: Commander Submarine Division Thirty-Two.
To: Commander Submarines, Atlantic Fleet.
Via: Commander Submarine Squadron Three.

SUBJECT: USS S-13 - Report of Second War Patrol.

1.
Forwarded. One possible sound contact with an
enemy submarine was made at 1830, 26 June 1942. Nothing was seen
through the periscope. Two other incidents are noteworthy. At
0342, 27 June 1942 the S-13 sighted a small single mast sail boat
about 60 feet long. The S-13 feels sure that this vessel should
be investigated if she has made no report of the presence of a
submarine to the Colombian authorities. At 0330, June 27, 1942,
the S-13 sighted a bright light on St. Andrews Island that made
three flashes spelling out "O" in Morse code. This light was
pointed directly at the S-13. I recommend that this incident be
reported to Colombian authorities in order that adequate investigation
can be made. It is possible that German submarines are receiving
aid from inhabitants of this island.

2.
Prior to this patrol the S-13 had been at sea train-
ing and on patrol for a period of thirty-eight days. After a
period of only three days in port S-13 was sent out on this patrol.
The S-13 remained submerged during daylight hours. Upon return
to port the crew and officers were tired. Practically 100% were
giving evidence of good morale. It is felt that when air con-
ditioning is installed that all day submerged patrols will be
easier on allhands and heat rashes will be reduced.

3.
Only one casualty of importance occurred. A
cylinder head cracked around the starting air valve recess. The
engineer force exhibited their initiative and ingenuity by blanking
off the air starting valve, thus permitting continued use of the
engine.

4.
Due to excess static, NAA in Washington was rendered
unintelligible. The S-13 then shifted to Balboa, C.Z. for Fox
schedules. It is recommended that all traffic for submarines in
Panama Sea Frontier be forwarded from NBA on 24 kc., regardless
as to whether they are operating in Pacific or Atlantic Sector.

0300 June 27, 1942 - Patroling to west of St. Andrews Island.
                          When shifting to float on both engines, there
                          was a casualty on the starboard engine -
                          appeared to be a cracked cylinder head.
                          Decided to leave it running and investigate
                          after submergence before morning twilight.
0330 June 27, 1942 - When about 6 miles west of St. Andrews Island
                          and headed directly towards it, a bright light
                          in the vicinity of North Cliff or May Hill gave
                          three long flashes. Light had not appeared
                          before and did not appear again during the
                          night, no answering flashes were seen from the
                          west. The moon was to the west of this vessel
                          at the time and it is possible that S-13 was
                          sighted. The light is not listed under
                          navigational aids and should be investigated.
                          Went westward to be in position to intercept
                          any vessels communicating with the beach.
.0505 June 27, 1942 - Submerged and commenced submerged patrol work-
                          ing in towards the south end of St. Andrews
                          Island. Periscope exposures every 10 minutes.
                          Examination of starboard engine revealed a
                          crack in the head of number two cylinder at
                          the air starting valve seat. By blanking off
                          the air starting valve, the engine was kept
                          in commission during the remainder of the
                          patrol.
1927 June 27, 1942 - Surfaced - Sighted Courtown Cays Light bear-
                          ing 60° T, distant 7 miles - Took departure
                          on course 153° T, returning to Submarine Base.
0518 June 28, 1942 - Patrolling, enroute to Submarine Base.
                          Submerged and commenced submerged patrol. One
                          half hour after sunrise made periscope
                          exposures every half hour. Seas were rough
                          and depth could not be maintained accurately
                          at 42 feet.
1943 June 28, 1942 - Surfaced and continued course to Submarine
                          Base, charging on one engine.
0537 June 29, 1942 - Patrolling enroute to Submarine Base.
                          Submerged and conducted usual day time en-

                          miles.
1650 June 29, 1942 - Identified Isla Grande and Los Farallones
                          Islands.

1845 June 29, 1942 - Surfaced. Due to rain squalls and poor
                       visibility, lost contact with entrance buoy
                       and did not pick up escort vessel. As
                       position was doubtful reported by radio to
                       Commander Submarine Squadron Three and in
                       obedience to his radio orders staod in, as
                       soon as increasing visibility enabled this
                       vessel to pick up Gatun Range.
2130 June 29, 1942 - Passed swept channel entrance buoy 100 yards
                       to port.
2140 June 29, 1942 - Contacted escort vessel and after several
                       delays caused by obstructions in the channel
                       stood in through mine fields.
0041 June 30, 1942 - Passed through breakwater.
0130 June 30, 1942 - Moored to pier 3, U.S. Submarine Base, Coco
                       Solo, Canal Zone. Patrol completed.

2. Weather. The weather was usually overcast with rain squalls
   although during many hours of the night the moon came through
   the clouds and the visibility was excellent. Seas were
   continually rough, condition three or four, and except when
   patroling in the lee of St. Andrews Island, maintaining depth
   control at periscope depth was difficult.

3. No unusual tidal conditions were noted.

4. All star sights were taken before morning twilight and after
   evening twilight. Because the moon frequently made the
   visibility good. The results were gratifying; usually giving
   a position that was accurate within four or five miles. In
   this connection it is pointed out that if a fix had not been
   obtained on the morning of making the landfall on St. Andrews
   Island, S-13 would have been well east of Courtown Cays and
   St. Andrews Island and might not have located land until after
   nightfall of that date. No bubble octant was used.

5. Contacts:
   1840 June 25, 1942 - Lat 10° 53' Long 80° 27' W.
                       Sighted a small sailing craft 2 miles to the
                       southwest. Boat was pitching heavily with
                       the sea and could not have been false
                       rigging on a submarine. Evening twilight
                       was setting in and when this vessel surfaced
                       sailing craft was out of sight.

1830 June 26, 1942 - Sound reported screws on the starboard
side and a low frequency ping at regular
intervals. Headed towards sound to present
a smallest possible target. Maintained
intermittent contact with sound bearings
until battery was almost discharged waiting
for enemy submarine, if it should turn out
to be such, to surface. From time to time
when sound bearing was reported dead ahead,
came to periscope depth to determine whether
any of target was visible. None was sighted.
In maneuvering submerged frequently made
attempts were frequently made to keep
in order to ram if sound contacts ahead
screws. However, bearings shifted frequently
and were never loud, hence it is believed
that at no time was contact possible.
Although the periscope was used at all
depths, nothing was sighted.
The Commanding Officer is not positive that
the noises heard were actually those of an
enemy vessel, but all sound operators insist
that they were sure the sounds heard were
those of screws and not sounds which might
emanate from a school of porpoises or waves
against the beach. In this connection
it is pointed out that the bearings were
frequently one hundred and eighty degrees
from the beach.
The following remarks were submitted to the
Commanding Officer by the Sound Operator:
The pinging sound picked up on the JK-8
receiver amplifier could be heard through a
frequency range of 15 to 21 Kcs.
This pinging sound appeared to be similar
in some respect to that of QC equipment except
the sound had a coarse note (not clear bell
like sound).
In my opinion, the output signal seemed to
have a slightly higher frequency at the
beginning of the signal and then swing to a
low frequency at the termination of the
signal.
Propeller noises were definite beats at about
300 rpm although no turn count was obtained.
Propeller noises were intermittent - when
they were stopped other noises could be heard
on that same bearing (internal ship noise.)

-4-

U.S.S. S-13

The pinging was never trained directly on
this vessel, but faint echoes were heard from
time to time. (The possibility of pinging
being from a fathometer is suggested).
Sound Operators (CRM and RM1c both sound school
grads.) are certain that the noises were from
a ship.

1730 June 27, 1942. When making a periscope exposure in a rough
sea halfway between Courtown Cays and St.
Andrews Island picked up a sailboat about
800 yards on port beam. As at least four
feet of the periscope were out of water at
the time, this vessel was undoubtedly sighted.

1050 June 28, 1942 - Lat. 11° N Long 80° 50' W. Sighted a
tuna boat patrol vessel 3 miles to the west-
ward. Boat was on a westerly course. (was
painted gray and appeared to be one of our
picket vessels.)

6. None.

7. None.

8. None encountered.

9. The only defect experienced that might have been serious
was the casualty to the starboard engine during the early
morning hours of June 27, 1942. However, the ship's force
blanked off the air starting valve on the affected cylinder
head and the engine was kept in full commission for the
remainder of the patrol.

10. Radio reception from NBA 24 k.c. was good. On 4155
there was considerable interference from stations in the
United States and San Juan, Puerto Rica. The only message
directed to this vessel from Coco Solo, C.Z. was received
complete. It should be pointed out that when there is any
message of importance for a submarine which is on a patrol
requiring all day submergence, such message should be
repeated at least two or three times during the hours of
darkness to insure its deliver. A reported sinking of a
Columbian Schooner within 40 miles of the S-13 on her patrol
station was not received until this vessel was returning
to her base although it occurred while S-13 was in the
vicinity.

U.S.S. S-13

It was the third transmission of this report, and it is
probable that the first two transmissions were made from
Balboa during daylight hours and consequently were not
received.

11. Sound conditions were good and the temperature variations
at various depths indicated the presence of density layers.

12. Although there was no serious illness on board, the
continued 13 and 14 hours submergence seemed to take the
starch out of the crew. Eating was very light at all times
although all hands generally managed to eat at least one
good meal a night. After the third day everyone was
afflicted with prickly heat and a few boils. As this
patrol was of short duration, no definite treatment for
heat rashes was prescribed. Some relief was found from
alcohol baths and cold swab downs. In the future this
vessel plans to take prescribed medical antidotes for
skin disorders on every patrol in sufficient quantities
to allow everyone adequate relief. Vitamin pills and salt
tablets were rationed daily.

13. Miles steamed - Surface 524.6; Submerged 234.4

14. Fuel oil expended - 3,705 gallons.

15. Factors of endurance remaining:

Torpedoes         Fuel         Provisions     Fresh Water
14 (allowance)    31,151       25 days        2,200 gals.

Personnel
8 days*

*Because of fatigue from the patrol immediately preceding,
the resistance of the crew was not up to normal.

16. Operation order designated time of leaving patrol area.

17. As pointed out before in this report, the ill effects caused
by continued all day submergence definitely affected the
efficiency of the crew. Prickly heat rash especially

-6-

was a continual source of irritation which had the patrol
continued many days longer would have become serious. It
is expected that the installation of air conditioning units
on board vessels of this division will definitely improve
the health and stamina of the crew. The Commanding Officer
believes that if the operation order is modified so as to
allow certain minor deviations from the prescribed patrol
routine and areas, greater initiative might be exercised in
taking advantage of reports of ship sinkings in the immediate
vicinity which are received on the broadcast schedules.

2.
In regard to the entry at 1920, June 24 the S-13
did not allow sufficient time after being granted "Affirm" before
reaching the net. Under the present procedure employed by the
Inshore Patrol, granting "Affirm" to the vessel means that the
order has been given to open the net; proceed cautiously. A
white light on the net vessels is lighted when the net is open.
The procedure is being studied by the Inshore Patrol with a
view to revision. Vessels of the Squadron are informed of the
procedure and necessity for proceeding slowly.

3.
The delay in entering the channel on the night
of June 29 was the result of a suspected vessel in the minefield.
Under the circumstances it was not considered advisable to open the
net until a thorough search had been made.

4.
Bubble octants will be very valuable when received.
It is hoped that delivery will be expedited.

5.
The sound contact reported at 1830, June 26, 1942
may have been propellers. An enemy submarine had been sighted
45 miles distant at 1115 that day. As the submarine dived and
planes were kept in the vicinity, it is improbable, but not
impossible, that it was the same one. On the other hand, the
noises of the surf on the rocks in the vicinity may have been
mistaken for propellers.

6.
The flashing light seen at 0330 June 27 and the
probable sighting by the sail boat at 1730 June 27 have been
reported to the Intelligence Officer of the 15th Naval District.
The possibility of enemy submarines using the density layers to rest
during the daylight has also been reported. A copy of this report
is being forwarded to the Commander Panama Sea Frontier.

2. Excessive regularity of air patrol as reported in para-
graph 6 is once again noticed. It is gratifying to note that the planes
of the Pacific Patrol are investigating submarines more closely than
heretofer.

3. It is gratifying to the Division Commander to note that
S-13 returned from a twenty-four day patrol in excellent material condi-
tion. The ship was above average as to cleanliness, as were the officers
and crew. The officers and members of the crew are to be congratulated
upon this exhibition of an excellent state of morale.

2. The weather during most of the patrol was good except for the clouds
   which invariably gathered during morning and evening twilight and pre-
   vented the taking of reliable star sights. The skies were overcast
   for almost fifty percent of the time but the seas were calm (condition
   0 to 2 from the southwest) until the last week when they reached con-
   dition 3 for several days. The wind was variable and light generally
   blowing from the southwest with force 1 to 2. Rain squalls were fre-
   quent both day and night.

3. As previously reported on patrols in this area the currents encountered
   were various and unpredictable although there seemed to be a general
   tendency towards an easterly set. Lack of successive star fixes pre-
   vented obtaining more detailed information.

4.  Good star fixes were obtained from sights by moonlight, and several
    fair fixes were obtained during the hours of darkness when there
    was no moon. The octant was tried by all officers and although a
    few good sights were taken, the platform of a submarine bridge was
    usually too unsteady to permit them to obtain the best results. It
    is believed, however, that with more practice, sights accurate to
    within 3 or 4 miles may be taken.

5.  None.

6.  Aircraft sighted:

    0700 to 1500
    July 11, 1942 - Sighted 2 navy PBY planes and numerous army
                    bombers and fighter planes ehile proceeding
                    down swept channel and in the Gulf of Panama.

    1125 July 16, 1942 - 07° 39' N. Long. 92° 23' W - Sighted 4 motored
                    army bomber 9 miles to northward on a westerly
                    course. Bomber came in to one mile on the star-
                    board beam then resumed its westerly course.

    1130 July 17, 1942 - Lat. 07° 32' N. Long 92° 20' W - Sighted 4
                    motored army bomber 10 miles to the northeast
                    on a westerly course. Bomber approached to
                    within one mile, exchanged recognition sig-
                    nals and proceeded in a westerly direction.

    1102 July 19, 1942 - Lat. 07° 30' N. Long. 92° 30' W - Sighted
                    a 4 motored army bomber 10 miles to southeast.
                    Bomber approached, exchanged signals and pro-
                    ceeded to westward.

    1158 July 19, 1942 - Lat. 07° 30' N. Long. 92° 35' W - Sighted 2,
                    4 motored bombers, one 10 miles to the south-
                    east and one eight miles south, both on westerly
                    courses. Both approached close aboard, exchanged
                    recognition signals and departed to westward.

    1058 July 21, 1942 - Lat. 07° 44' N. Long. 92° 04' W - Sighted a
                    4 motored army bomber 10 miles to the north-
                    east. Plane approached to within 4 miles of
                    this vessel then headed westward without
                    exchanging any recognition signal.

    1118 July 25, 1942 - Lat. 07° 26' N. Long. 92° 12' W - Sighted
                    4 motored army bomber dead ahead, distance
                    4 miles, headed for this vessel. Bomber
                    approached close aboard, circled this
                    vessel twice and continued to eastward.

    1202 July 28, 1942 - Lat. 07° 28' N. Long. 92° 12' W - Sighted a
                    4 motored army bomber 10 miles to the northeast
                    on a westerly course. Bomber came close aboard,
                    exchanged recognition signals, circled this
                    vessel three times and continued to proceed in
                    a westerly direction. Plainly printed on plane
                    "Hell from Heaven".

1208 July 29, 1942 - Lat. 07° 31' N. Long. 92° 30' W - Sighted
4 motored army bomber 11 miles to eastward
on a northwesterly course. Plane came close
aboard, exchanged recognition signals, cir-
cled this vessel once and proceeded on a
westerly course.

1050 July 30, 1942 - Lat. 07° 28' N. Long. 92° 20' W - Sighted
4 motored army bomber 10 miles to north-
east on a westerly course. Plane came within
about 8 miles of this vessel but continued on
a westward course and apparently did not sight
us.

1120 July 30, 1942 - Lat. 07° 29' N. Long. 92° 25' W - Sighted
4 motored army bomber 6 miles to the east on
a westerly course. Plane came close aboard,
exchanged recognition signals, circled this
vessel once, and proceeded to westward.

1208 July 30, 1942 - Lat. 07° 30' N. Long. 92° 30' W - Sighted
4 motored army bomber 9 miles to the north-
east on a westerly course. Plane came close
aboard, exchanged recognition signals, and
proceeded to westward.

1110 July 31, 1942 - Lat. 07° 33' N. Long. 92° 26' W - Sighted
4 motored army bomber 6 miles to northward
on a westerly course. Plane came close
aboard, circled this vessel, exchanged recog-
nition signals, and proceeded to westward.

1130 July 31, 1942 - Lat. 07° 31' N. Long. 92° 29' W - Sighted
4 motored army bomber 8 miles to eastward on
a westerly course. Plane came close aboard,
exchanged recognition signals, circled this
vessel, and proceeded to westward.

1150 August 3, 1942 --Lat. 07° 32' N. Long. 90° 50' W - Sighted
4 motored army bomber 12 miles to the south-
east on a westerly course. Upon sighting this
vessel when 6 miles on our starboard beam, plane
turned towards us and apparently dropped several
objects into the sea, one of these objects ap-
peared to explode and it is believed that all
were bombs, a number of which failed to deton-
ate upon contact with surface of ocean. Plane
then came close aboard, circled and exchanged
recognition signals, then proceeded to westward.
The words "ALICE LOUISE" were painted on this
bomber.

7. None.

8. None observed.

9. None.

10. Radio reception from NBA, 24 k.c. was good and all schedules were
    readily copied. There was considerable interference from various sta-
    tions on 4155 and 8310 k.c.s. and it was always difficult to raise NBC
    on account of this. When frequency was shifted to 4135 and 8270 kcs,
    August 3, 1942, considerable improvement was noted. Only one unident-
    ified commercial station seemed to interfere on these frequencies.
    Reception on the loop antenna was good to a depth of forty to forty five
    feet. When the loop of the antenna was in the plane of transmission the
    signal could be copied to a depth of fifty feet. While copying messages
    there is usually an intermittent "fading out" of the signal which is due
    to the rolling of this vessel in a heavy sea. Therefore when sending
    traffic "blind" from Coco Solo, C.Z. in order to guarantee the immediate
    reception of important messages which are transmitted on 4135 and 8270
    kcs, it is recommended that each group be sent double as it frequently
    happens that some messages received on these frequencies has missing
    letters and groups even when the reception appeared to be good when the
    transmission began.

11. As previously reported by submarines patrolling in this area, the varia-
    tion of the temperature at various depths indicates the presence of
    density layers. Typical readings taken several times showed the follow-
    ing temperatures:

    Surface 80° F
    40 feet 76° F
    60 feet 74° F
    90 feet 70° F
    120 feet 68° F

    There was no opportunity to test sound conditions.

12. In general the health of the crew was excellent, there being only a few
    minor cases of skin rashes. Each member of the crew took one vitamin
    pill a day and it is believed that they definitely helped to keep every-
    one energetic. There was no general "slacking off" in the performance
    of the men during the last week of this patrol as there was during the
    previous patrol when vitamin pills were not used. Because of the com-
    paratively few hours spent submerged the ship was fairly comfortable at
    all times.

13. Engine miles steamed:
    Surface - 4783
    Submerged - 78.1

14. Fuel oil expended - 26,012 gallons.

15. Factors of endurance remaining:

    Torpedoes | Fuel | Provisions | Fresh Water
    14 (Allowance) | 11,546 | 7 days | 1,000 gallons.

    Personnel
    Indeterminate - Probably two weeks more under ideal conditions.

16. Operation order ended patrol. It is believed that the limiting factor
    would have been suitable provisions. The size of the ice box on this
    vessel limits the fresh provisions that can be carried to about a
    thirty days' supply. Although fresh water was not rationed there was
    more than an adequate supply because the ship's evaporators were run
    at all times while on the surface.

17. It is believed that a thirty day patrol is not too long for a govern-
    ment type "S" boat when conditions permit many hours of surface
    cruising. With the installation of air conditioning, more adequate
    ice box facilities and the piping of #3 main ballast tank to permit
    the carrying of fuel oil there, if necessary, it is believed that this
    type of submarine could make a forty or forty five day patrol.

U.S.S. S-13 REPORT OF FOURTH WAR PATROL
PERIOD FROM 6 SEPTEMBER 1942 TO 23 SEPTEMBER 1942.
AREA: PANAMA SEA FRONTIER, PACIFIC SIDE.
OPERATION ORDER: Commander Submarines, Pacific Group
(Comsubdiv-31) mailgram 032000 of
September, 1942.

TIME ZONE PLUS 5.

1. 0715, 6 September 1942 - Departed Submarine Base, Coco Solo, Canal
Zone and transited canal southbound,
mooring starboard side to U.S.S. BOWDITCH
at pier 13 George, Balboa, Canal Zone, at
1600.
0650, 7 September 1942 - Departed Balboa, C.Z., enroute to patrol
station using route Red.
1246, 7 September 1942 - Made trim dive. Lat. 08-12-N. Long 79-
30-W.
1315, 7 September 1942 - Surfaced and proceeded at 10 knots.
1830, 7 September 1942 - Passed point Cano enroute to station.
2210, 7 September 1942 - Passed point Sail Affirm.
8-11 September 1942 - Enroute to patrol station.
0900, 11 September 1942 - Arrived on station. Lat. 06-30-N. Long.
90-00-W. During time on station patrolled
to westward during daylight hours and to
eastward during darkness, adjusting speed
so as to arrive at the initial point at
dawn each day. Dove at start of morning
twilight each day, except on 14 September
1942, and surfaced after sunrise. On 14
September 1942, remained on surface long
enough to get morning stars and then dived.
Training dives were made at various other
times but because of stern plane casualty
with consequent poor depth control, this
practice was discontinued on 19 September
and decision was made that except for
morning dive to only dive in case of
emergency.
1700, 19 September 1942 - Received Commander Submarine Squadron
Three despatch 191925 of September direct-
ing return to Balboa.

1930, 19 September 1942 - Enroute to Initial point.
0300, 20 September 1942 - Arrived Initial point and proceeded to
                               Balboa, Canal Zone, via route Red.

                               S-12 at pier 18 George, Balboa, C. Z.

2. Weather during most of patrol was bad (Uncomfortable). Skies were
   overcast about 80% of the time and only one or two reliable star sights
   were obtained. The sea was very choppy on top of a long deep swell
   from the southwest. The wind averaged force four, also from the south-
   west. Rain squalls were frequent both day and night.

3. The current obtained from fairly unreliable fixes indicated a
   fairly constant easterly set of about one knot.

4. As noted above, star fixes were not too reliable. Attempts were
   made to use the bubble octant with not very satisfactory results.

5. None.

6. Aircraft sighted:

   1205, 12 September 1942 - Lat. 06-23-N. Long. 92-10-W. Sighted
                               4 motored army bomber eight miles to
                               the north on a westerly course at about
                               800 feet altitude. Plane closed ship and
                               recognition signals were exchanged. Plane
                               departed on southerly course.
   1235, 12 September 1942 - Lt. 06-23N. Long. 92-12-W. Sighted
                               4 motored army bomber six miles to the
                               west on a southerly course at about 800
                               feet altitude. Plane continued on
                               southerly course.
   1122, 16 September 1942 - Lat. 06-29-N. Long 92-20-W. Sighted
                               4 motored army bomber eight miles to the
                               west on a southerly course at about 1500
                               feet altitude. Plane continued on same
                               course.
   1200, 18 September 1942 - Lat. 06-26-N. Long. 92-25-W. Sighted
                               4 motored army bomber six miles to north-
                               west on a xoutherly course at 1500 feet
                               altitude.

7. None.

U.S.S. S-13

8. None.

9. Stern plane casualty believed to be bent vertical tilting rod.
   Stern plane motor required to carry about 150% overload which caused
   periodic cutting out by overload trip. Unable to operate plane by
   hand.

10. Radio reception was good.

11. No density layers noted and no means for determining sound
    conditions.

12. General health of crew was excellent. There being only one minor
    case of stomach sickness which was cleared up in one days time. The
    air conditioning was a big help. It was particularly noted that
    personnel having had the usual amount of sleep seemed to be normally
    refreshed.

13. Engine miles steamed:

    Surface - 4190 miles.
    Submerged - 27 miles.

14. Fuel oil expended - 19, 631 gallons.

15. Factors of endurance remaining:

    Torpedoes | Fuel | Provisions | Fresh Water | Personnel
    13        | 13,834 | 15 days    | 2500 gallons | 20 days.

16. Operation order ended patrol. Provisions would undoubtedly have
    been limiting factor.

17. During patrol the new rocket pistol (Buck Rogers Pistol) and the
    Very pistols were tested. The rocket pistol was very satisfactory,
    but it was noted that in order to allow for complete burning of flares,
    pistol must be fired straight up. The Very pistol test was very un-
    satisfactory, one shell out of 14 fired operated properly. It has
    been the policy on this vessel to consider the Very pistol as a standby
    for the rocket pistol but because of these results this practice has
    been discontinued.
