HISTORY OF SHIPS NAMED POLLACK

The nuclear-powered submarine POLLACK (SS(N) 603) is the second ship
of the fleet named for a gadoid food-fish resembling the true Cod, but
with the lower jaw projecting and without the barbel.

The first POLLACK (SS 180) was built by the Portsmouth Navy Yard,
New Hampshire. Her keel was laid 1 October 1935 and she was launched 15
September 1936, under the sponsorship of Miss Anne Carter Lauman, daughter
of Captain P. G. Lauman (CC), USN, Production Officer at the Portsmouth
Navy Yard. The fleet submarine was placed in commission on 15 January
1937, Lieutenant Clarence E. Aldrich, USN, in command.

POLLACK had an overall length of 300 feet 7 inches; extreme beam,
25 feet 1 inch; standard displacement of 1,330 tons; mean draft of 13
feet 10 inches; submerged displacement of 1,997 tons; designed speed of
19.25 on the surface, 8.75 knots submerged; and a designed depth of 250
feet. Her designed complement was 5 officers and 45 men. She was armed
with six 21-inch torpedo tubes, one 3-inch .50 caliber gun, two .50
caliber guns, and four .30 caliber guns. She carried sixteen torpedoes.

POLLACK stood out of the Portsmouth Navy Yard on 7 June 1937 for a
shakedown training cruise which took her to Guantanamo Bay, the
Netherlands West Indies; the Virgin Islands, Puerto Rico, the Bahama
Islands, ports of Texas, and the Panama Canal. She returned from this
cruise to Portsmouth on 4 September 1937 and was underway on 29 November
for the west coast of the United States. She reached her new base at
San Diego, California, on 19 December 1937 and spent the next eleven
months in a rigorous schedule of maneuvers along the western seaboard
with Submarine Division Thirteen, Scouting Force. POLLACK shifted to
base at Pearl Harbor on 28 October 1939. Except for periods of overhaul
in the Mare Island Navy Yard, she remained in Hawaiian waters until the
outbreak of World War II. She was enroute from Mare Island to Hawaii
when the Japanese made their infamous attack, she entered Pearl Harbor on
9 December 1941.

POLLACK, GUDGEON and PLUNGER were the first American submarines to
invade the Empire waters of Japan and were also the first Pacific Fleet
Submarines to make the hazardous 3,400-mile voyage from Oahu to Japan.
POLLACK cleared Pearl Harbor on 13 December 1941 and was off the coast
of Honshu, Japan, a few hours before midnight of 31 December when she
sighted the light of a ship and commenced a surface approach. Unable
to cross the enemy's track when she found herself between the moon and
the target, she dived to make the first night-periscope attack of the
Pacific Fleet Submarine Force. The dim view afforded by the periscope

— page 3 —
SHIPS NAMED POLLACK

did not allow for ranging and course estimation and two torpedoes missed
their mark, causing Lieutenant Commander S. P. Mosely to take a "dim view"
of night-periscope attacks. However, improvements developed from the
need found in pioneer tactics such as this resulted in "light treated"
optical systems in periscopes in the summer of 1942 and two years later
a true night periscope of even greater efficiency became available.

POLLACK stalked a merchant ship in broad daylight off Tokyo Bay on
3 January 1942 but that freighter escaped while two aircraft circled
over the sea to keep her down. She damaged the 2,700 ton cargo ship
HEIJO MARU on 5 January and made her first kill two days later when she
sent the 2,250-ton cargo ship UNKAI MARU NO. 1 to the bottom (34°-27' N;
138°-59' E.). This enemy was the first officially confirmed victim of
the Pacific Fleet Submarine Force. On 9 January 1942 the 5,387-ton
freighter TEIAN MARU was sunk (35°-00' N; 140°-36' E.) by a night-surface
attack which required great competence and daring under any circumstance,
and a doubled measure of skill for pioneer POLLACK who was not equipped
with radar. Her last torpedo was expended in an unsuccessful attack on
a destroyer in the early morning darkness of 10 January and she
terminated her first war patrol at Pearl Harbor on 21 January 1942.

POLLACK was underway from Pearl Harbor on 18 February 1942 and set
course to intercept enemy cargo ships carrying war material to Nagasaki
by way of the Formosa Channel. She let go her first salvo in this traffic
lane the night of 11 March, and when the enemy zigged away from two torpedo
wakes, she let go a single torpedo which passed under the freighter without
effect. A third try with a single torpedo resulted in a tremendous
explosion which sank the 1154-ton cargo ship FUKUSHU MARU (30°-53' N; 126°-
20' E.).

POLLACK sank two sampans with gunfire about three hours after
midnight of 12 March 1942. She then turned her attention to a cargo
ship who escaped the erratic run of two torpedoes, then deftly maneuvered
clear of two others when their wakes were spotted on the moonlit surface.
Without time to reload bow tubes or swing for a stern shot, POLLACK manned
her 3-inch deck gun whose first shot found its mark on the enemy's bridge.
The automatic firing device jammed after this first shot and only twelve
more salvos could be fired by hand before the freighter's superior speed
put her safely out of range of that fighting submarine. POLLACK
continued to patrol the traffic lanes between Korea and ports of Honshu
until 13 March 1942 when she was directed to attempt the interception of
enemy aircraft carriers reported bound from Yokosuka for Staring Bay,
Celebes. She found no trace of the enemy force by 22 March when the
search was called off and returned to Pearl Harbor on 8 April 1942.

POLLACK departed Pearl Harbor on 2 May and was in waters of the
Japanese home islands on 12 May when she battle-surfaced to riddle a
600-ton patrol vessel with 3-inch and .50 caliber hits. This target
settled by the stern and burned furiously at every point above the
waterline. On 14 May 1942 POLLACK received word of an enemy carrier
heading for Kure and sped across the south bound traffic lanes from

2

SHIPS NAMED POLLACK

Tokyo in an attempt to intercept. As she continued in the carrier's
track on 19 May, she took time out to sink four sampans, including one
with a regular cargo vessel bridge. A high-speed ship crossed ahead in
the inky darkness which marked the first morning hours of 21 May, and
POLLACK closed the track at full speed. Four torpedoes missed their
mark as an enemy destroyer opened out to the right of the aircraft
carrier which turned away from the deadly salvo. There was no chance
of POLLACK being able to attain the speed necessary for a second try.
She destroyed a trawler on 31 May and after an uneventful search for the
defeated enemy units retiring from the historic Battle of Midway,
returned from her third war patrol to Pearl Harbor on 16 June 1942.

POLLACK underwent four months of overhaul in the Pearl Harbor Navy
Yard, then put to sea for her fourth war patrol on 10 October 1942. Before
she reached her assigned area she was ordered back to Midway, arriving 23
October 1942. She fueled to capacity and stood out of the Midway channel
that same day to patrol the approaches to Truk in an attempt to intercept
crippled enemy ships believed enroute to that enemy stronghold from sea
battles in the Solomon Islands. When sufficient time had elapsed for the
crippled enemy ships to reach their bases, she was assigned to patrol in
the northern sector of the Truk area. There were no contacts with enemy
shipping during the entire patrol and POLLACK returned to Pearl Harbor on
29 November 1942.

POLLACK's fifth war patrol was again spent in waters of the Japanese
Empire. After clearing Pearl Harbor on 31 December 1942, she ran into
mountainous seas while guarding the Tsugaru Strait, and continued to be
plagued by winds of gale force, snow and hail storms as she patrolled
along the coast and southeast of Shiraya Saki. Her only target of
opportunity was a fast freighter, intercepted on the night of 21 January
1943. As she moved in for the kill in bright moonlight, three shells
whistled overhead from the enemy's stern gun. That target put on more
speed but POLLACK managed to close the range to 2400 yards and fired four
torpedoes for undetermined results before she was outdistanced. She
terminated her fifth war patrol at Pearl Harbor, 10 February 1943.

POLLACK spent her sixth war patrol in an area normally low on enemy
contacts, the shipping lanes between the Gilbert and Marshall Islands.
She put to sea from Pearl Harbor on 6 March 1943 and intercepted a
freighter in the sealane between Jaluit and Makin Atolls on the afternoon
of 20 March 1943. Forced to break off the attack when spotted by two
patrol vessels, she evaded their depth charges and continued chase until
after daybreak the next morning when she gained ahead to sight the
freighter coming out of the rain with one escort on the port quarter.
She sent three torpedoes streaking for the target which took a hit and
became enveloped in a smokey haze with a list to port. As this spectacle
was observed through the periscope, POLLACK was rocked by the tremendous
explosion of an aerial bomb and a wall of water rose to block the target
from view. The first string of depth charges exploded well astern as she
went deep but a second depth charge attack sent paint chips flying. Two
enemy escorts milled over the surface for another attack before they were
left astern.

POLLACK let go of three torpedoes at a freighter attempting to
enter Jaluit Lagoon on 4 April 1943 and was again forced down by aerial
bombs. By 9 April her patrol began to assume the aspect of an illegal
blockade of Jaluit Lagoon. One heavy laden vessel had been prevented
from entry and others which had been observed in the lagoon since the
end of the preceding month, were apparently afraid to leave. Agressive
patrol found the area outside the lagoon to be devoid of other enemy
shipping and this exasperating situation was aptly reflected by entry
in POLLACK's war diary: "We were very much tempted to send them a
message daring them to come out." She terminated her sixth war patrol
at Midway on 18 April 1943.

Underway for her seventh war patrol, POLLACK cleared Midway on 10
May 1943 to reconnoiter Ailuk Atoll and Wotje Island, then patrolled
to the south and west towards Schischmarev Strait. On 18 May she found
the 2,110-ton ex-gunboat TERUSHIMA MARU standing out of the channel north
of Inijun Island. Two torpedo hits blasted that enemy from the surface
of the ocean as POLLACK hunted deep water to evade the last of seven
depth charges dropped by the prowling escorts. She cleared that area and
was off Jaluit Atoll the next afternoon to intercept the 5,350-ton
converted light cruiser BANGKOK MARU standing out from the southeast pass.
A deadly salvo of three torpedoes sent chunks of that enemy's stern more
than three hundred feet into the air and she settled beneath the waves in
latitude 5°-37' North, longitude 169°-27' East. POLLACK dodged twenty-
one exploding depth charges before she gave the hunters above the slip
to resume patrol of the shipping lanes between Jaluit and Kwajalein Atolls.
When she used her transmitter on 13 June to acknowledge cancellation of
change in orders, POLLACK apparently had her position fixed by the search
equipment of Japanese patrol bombers. From that day on she became the
object of an intensive search from the air which greatly hampered her
opportunities of attack. She escaped these killers and terminated her
seventh war patrol at Pearl Harbor on 25 June 1943.

POLLACK spent her eighth war patrol off the east coast of Kyushu,
Japan. She left Pearl Harbor astern on 20 July 1943 and moved in on a
three-ship convoy in Empire waters on the afternoon of 6 August. Two
torpedoes missed their mark and she was held down by two destroyers
while the convoy grasped for distance. This game of hide-and-seek
terminated two hours later when she had maneuvered clear for an "end-
around" on the surface. She gained ahead for a second try and was
rewarded by the sight of a hit which threw a geyser of water as high as
the enemy's bridge, followed a few minutes later by two flashes and
explosions (27°-54' N; 140°-51' E.). She was unable to gain position
for another attack and patrolled to the northwest and northeast of Tori
Shima until 21 August when she set course for Bungo Suido.

In the early morning darkness of 27 August 1943, POLLACK picked out
one of five merchant ships off the coast of Kyushu and pressed home an
attack which sank the 3,520-ton passenger-cargo ship TAIFUKU MARU (32°-
27' N; 132°-24' E.). A destroyer sped back down the torpedo track and
was discouraged by two torpedoes from POLLACK just moments before she

4

SHIPS NAMED POLLACK

went into a deep and silent run which took her from the scene of a
fierce counter-attack. Her last torpedoes were expended on 3 September
1943 when she slipped past a destroyer and let go with four torpedoes
which sank the 3,521-ton cargo ship TAGORNOURA MARU (34°-10' N; 140°-
12' E.). Her men counted the explosion of seventeen depth charges in
the distant sea while POLLACK outwitted the escort and made her way
clear. She returned to Pearl Harbor on 16 September 1943. The next four
months were taken up by overhaul in the Pearl Harbor Navy Yard.

POLLACK got underway from Pearl Harbor on 28 February 1944 and
battled heavy seas as she entered the assigned area of her ninth war
patrol off Nanpo Shoto on the 18th of March. Two days later she made a
night surface attack and watched two torpedoe hits blow the 1327-ton
freighter NAKUYU MARU to pieces (30°-53' N; 140°-42' E.). Yellow flames
lit up the sky as the target disappeared from sight. The flaming oil
continued to burn on the surface for sometime afterward, clearly
illuminating a submarine chaser which raced frantically about and dropped
an aimless pattern of depth charges. POLLACK quietly withdrew and knifed
through heavy seas in chase of a convoy. She slowly gained and pressed
home the first attack an hour after midnight of 24 March 1944. Two
explosions were immediately followed by a great column of red and orange
flame where the target had been. POLLACK then swung and fired four
deadly salvos which exploded in a freighter and left it aflame. She next
turned her attention on a second cargo ship and heard two resounding
explosions in that target as she withdrew from the scene near the dawn.
The victim of her first attack was a 300-ton submarine chaser but the
other targets were never identified.

Towards the evening of 3 April 1944 POLLACK found herself in an
unusual situation. Commander Lewellen stated in his report: "With
ships all around us the only problem was to pick out one at which to
shoot. I felt, and probably acted very much like a small child in a
candy store trying to get the most for his two pennies." She sent the
last of her torpedoes streaking for one of some twenty cargo ships and
was rewarded by the sound of two tremendous explosions, followed by
muffled ones as the 2,814-ton passenger-cargo ship TOSEI MARU slipped
beneath the sea in latitude 30°-00' North, longitude 139°-44' East. With
all torpedoes gone, she spent the next three and a half hours dodging
more than fifty depth charges and aerial bombs. She cheated the milling
escorts of their prey and returned to Midway on 11 April 1944.

POLLACK's tenth war patrol was conducted off the Nanpo Shoto. She
cleared Midway on 6 May 1944 and was sixteen days out to sea when she
moved in on about ten merchantmen with several escorts. She scored
torpedo hits which sank the 1,270-ton Japanese destroyer ASANAGI (28°-
20' N; 138°-57' E.) and was held down by a fierce counter-attack while
the remaining ships of the convoy made good their escape. She returned
to Pearl Harbor on 7 June 1944.

POLLACK cleared Pearl Harbor for her eleventh war patrol on 15
July 1944. She touched at Majuro, Marshall Islands, and then steamed
on lifeguard station in support of the air strikes made on Woleai Island
the 1st of August. She was off Yap Island 4-5 August for similar duty,
then patrolled in the Yap-Palau area, taking time out to shell the
phosphate plant on Fais Island on 27 and 30 August. She terminated
her eleventh war patrol at Brisbane, Australia, on 12 September 1944.

POLLACK underwent a refit period at Brisbane, then got underway
on 6 October for exercises with HMAS GEELONG until the 10th. She then
steamed by way of Mios Woendi, Padaido Islands, to Pearl Harbor where she
arrived on 18 November for training operations off Oahu with units of the
Pacific Fleet destroyer force. She was underway from that port on 25
January 1945, enroute with PERMIT (SS 178) to the east coast of the
United States. She transited the Panama Canal on 13 February and reached
the Submarine Base, New London, Connecticut, on 24 February 1945. The
remainder of her career was spent as a training ship for men of the
Submarine School at that base. She entered the Portsmouth Navy Yard on
14 June for inactivation and was decommissioned there on 21 September
1945. Her name was stricken from the Navy List on 29 October 1946 and
she was sold for scrapping on 2 February 1947.

report follow.

        3.      The Commander Submarines, Pacific Fleet, concurs
in the remarks of the Division Commander in the last paragraph
of his letter of comments. The patrol was carried out in an
energetic and aggressive manner.

        4.      The failure in communications between bridge
control and conning tower during the attack on January 5 is
noted. This was undoubtedly due to the state of the weather at
the time and the difficulty of passing the word from the conning
tower to the bridge. Voice tubes are being installed on all
submarines of this command between conning tower and the bridge
to correct this difficulty.

        5.      It is noted that previous reports of Japanese
destroyers being equipped with echo-ranging equipment on 18 kilo-
cycles is confirmed. Apparently not all destroyers are so equipped,
and apparently those not equipped with supersonic conduct a very
inefficient listening watch.

        6.      Steps are being taken to increase the allowance
of 7 x 50 binoculars to twelve, with a reserve supply on each
tender and base.

U.S.S. POLLACK REPORT OF 1st WAR PATROL.
PERIOD FROM 13 December to January.
AREA Four.
ZONE TIME plus 10½ to minus 10 enroute; minus 10 in area.

1. NARRATIVE
13 December. Left Base for Patrol Area Four, which is
          defined as that area north of Lat. 34°-10'
          north and between the north and south lines
          extending through IRO SAKI and INUBO SAKI.

14 December. Made quick dive, went to test depth, every-
          thing satisfactory.
          Set speed at 9 knots (80% load on one main
          engine) to increase endurance, which is cal-
          culated as follows:

          9 KNOTS (WITHOUT ZIG ZAG)
17.5 days to arrive, using                     30,700 gals.
19 days to return, using                       33,000 "
10% safety factor                              8,000
                                     Total     71,700 gals.
On Board at 1700/14                            84,200 "
Left for use on station                        12,500 gals.

          12 KNOTS (WITHOUT ZIG ZAG) (2 Engines 80% Load)
13 days to arrive, using                       37,800 gals.
19 days to return, (1 engine)                  33,000 "
10% Safety factor                              8,000 "
                                               78,800 gals.
On Board                                       84,200 "
Left for use on station                        5,400 gals.

          Higher speeds use more fuel. By careful
          conservation of water, air, and electricity
          we will probably increase endurance.

15, 16, 17,
18 December. Uneventful. Made training dive and held
          drills daily.

20 December. Training dive. Number one main motor com-
          menced sparking heavily, attempted repairs.

## The Power of Visuals: How Images Enhance Communication

In today's fast-paced world, effective communication is paramount. While text-based information has its place, the strategic use of images can significantly amplify the impact and clarity of your message. From marketing campaigns to educational materials, images offer a unique ability to engage audiences, convey complex ideas, and evoke emotions in ways that words alone often cannot.

### Why Images Matter in Communication

1.  **Increased Engagement and Attention:** Our brains are hardwired to process visual information rapidly.

Subject: Comments on POLLACK War Patrol.

This patrol was conducted under very adverse
weather conditions. Head winds enroute area delayed scheduled
time of arrival by about five days with consequent increased
fuel consumption and reduction in maximum period station could
have been maintained. While the POLLACK left station early
due to expenditure of torpedoes she could have stayed only
about five days longer to arrive Pearl with 8000 gallons
(10% capacity) of fuel. Despite extremely rugged conditions
the health and morale of the crew, food etc. would have permit-
ted remaining on station until fuel expenditures required
return. Fueling at Midway enroute to station should insure
the submarine fuel endurance for remaining on station about
20 days regardless of weather encountered.

It is gratifying to note that the vapor compres-
sion stills adequately took care of the fresh and battery water
situation. The crew was unable to disassemble coils for
cleaning.

The air conditions apparatus paid for itself
in increased habitability, reduction of battery grounds, and
providing enough fresh water to wash clothes.

Washing machines should be considered a necessity.

Voice tube arrangement from both sides of bridge
to conning tower with outlets for helmsman and man at torpedo
firing key must be provided. Lack of communication (Plus
green seas over bridge) caused an unnecessary torpedo expendi-
ture on the night of January 5, for which no one should be
censored.

The problem of having dry binoculars can only be
met by at least doubling the present allowance.

There is very good evidence that magnetic ex-
ploders functioned properly on attacks made on 7 and 9 Jan-
uary. Suggest Commanding Officers in the future report
depth settings of torpedoes fired and estimates of draft of
targets.

Subject: Comments on POLLACK War Patrol.

1. Voice Tube. The voice tube from the bridge to
the Conning Tower has been authorized by Commander Submarines,
Pacific Fleet and will be installed prior to the departure of the
POLLACK for another patrol.

2. Main Motors. The sparking on #1, #3, and #4 main
motors is considered a serious situation. It will be the con-
trolling job during the refit period. The Base is undertaking to
correct this defect and efforts are being made to obtain the ex-
pert advice of a Factory representative of the Elliot Co., or
some other company.

3. Binoculars. The lack of sufficient good binoculars
is a recognized fact. It is recommended that at least forty
pairs of 7 x 50 binoculars be requisitioned by despatch and if
necessary have them shipped by air mail to insure that submarines
going on patrol have them. It is suggested that every effort be
made to obtain a watertight glass.

4. Vapor Stills. It is noted that the ship's force
was unable to disassemble the vapor stills for cleaning after 400
hours in use. Attention is invited to Commander Submarines,
Scouting Force Bulletin No. 34-41 in reference to scale removal.
No difficulty should be encountered if the contents of paragraph
3 of this bulletin are carried out. This bulletin was published
after the departure of the POLLACK on patrol.

5. Main Engines. Main engines #3 and #4 will be
given a complete overhaul. The Relief Crew will start the over-
haul. This should be a good test of what can be expected of a
Relief Crew. The entire overhaul will take between three and
four weeks.

6. Coolers. The zincs in the coolers will be renewed.
This is a long tedious job but will be accomplished during the
refit period.

1. The POLLACK was withdrawn from her originally
assigned area after four days in that area and given another
assignment together with two other submarines. This change
in plan necessitated the use of more fuel than ordinarily would
have been used and accounts for POLLACK returning from patrol
on the fiftieth day. During the short time that POLLACK was
in the area, the Commanding Officer showed a very aggressive
spirit.

2. This is the first instance where a submarine
of this Force has been permitted by weather or other circum-
stances to use the gun against the enemy. It is to be noted
that when two sampans threatened interference with his opera-
tions, he sank them both by gunfire. This not only gave him
freedom of movement, but at the same time started the destruc-
tion of Japan's vital fishing fleet. It is regretted that on
the attack by gunfire on a merchantman, range could not be
maintained due to the position of the gun aft. It is consid-
ered, however, that a further chase could have been made to
get into a favorable firing position once more since the tar-
get is listed as a 13½ knot ship. The blinding effect of
night gunfiring is again noted and further efforts will be
made to obtain flashless powder for use on submarines. In
the meantime, submarines must arrange some signal for the
pointer to give just before firing, such as blowing a whis-
tle, in order that the gun crew may close their eyes just be-
fore the flash.

3. The Commanding Officer states that on his at-
tack at 1330, 10 March, he had probably overestimated the tar-
get's masthead height and therefore the range was in error.

Subject: U.S.S. POLLACK - Report of Second War Patrol.

1. This is the second war patrol to be conducted
by the U.S.S. POLLACK and whereas the results were not as
good as was hoped for, it was not because of lack of effort
or determination on the part of the commanding officer.

2. It is of interest to note the success of our
submarines firing at reasonably short ranges on a 180°
a track recently used with much success by the British submarine
service in the Mediterranean.

3. It is considered a needless expenditure to fire a
torpedo at a 150 foot ship as was done on 12 March 1942. Such
shipping should either be sunk by gun fire, else allowed to
pass by.

4. This the first time the deck gun and 50 caliber
machine guns have been used by one of our submarines on patrol.
Much speculation has been made as to whether or not Sampans
carrying lights are some type of patrol vessels. The two Sampans
sunk on this patrol indicate they are only fishing boats and are
no cause for a submarine to dive as has been done in many cases
in the past.

5. It is considered that the commanding officer showed
good judgement in assuming that the vessel sighted on 26 March,
1942 was some type of "Q" ship and should be given a wide berth.

6. The POLLACK is due for a Navy Yard overhaul after
her next patrol at which time her main storage batteries will
need renewal. Considering the time since last overhaul, age
of ship and type of operations recently conducted she is consider-
ed to be in very good material condition. Cracks in cylinder
liners is a new casualty for this ship will be investigated to
determine the probable cause.

1. The Squadron Commander concurs in the comments

2. It is undesirable to clean the Kleinschmidt stills
at sea, and they should be cleaned at the end of 200 hours use
to eliminate the collection of too much scale. With two stills
aboard the submarine she has a capacity of 12000 gallons of water
plus the quantity carried in her tanks. This should be suffi-
cient to make it unnecessary to clean stills while on patrol.
The Submarine Base is equipped and fitted to disassemble, clean
and repair these stills with much less effort than is required
by the ship's force while on patrol. Experiments are being
performed to make this operation an easier task.

           1. The POLLACK conducted an aggressive patrol
and it is unfortunate that no supply vessels were sighted.
The night attack on the carrier was a failure due to the
large speed error. Enemy speed was obtained by estimate
only since it was too dark to take a range and the POLLACK
is not fitted with a keel mounted QC. This again emphasizes
the necessity of firing with calculated data rather than by
seaman's eye whenever possible.

U.S.S. POLLACK, Third War Patrol, Report of.

1.
with relative high speeds employed in attempting to intercept
a damaged carrier, with consequence increased fuel consumption
materially reduced the maximum period station could be maintained.
The first three war patrols made by this vessel were for a period
of 39 days, 49 days and 46 days respectively and the limiting
factor of endurance remaining in each case was fuel. This clearly
indicates the necessity of employing the most economical speed
proceeding to, on, and returning from station.

2.
On this patrol a practice was followed of keeping
one torpedo tube forward and one aft flooded each night, tubes
being rotated daily. The outer doors were kept closed. This
procedure caused severe pitting in war heads and after bodies of
the flooded torpedoes, pittings extending completely through the
war heads in many places. By intelligent compensation, together
with reasonably safe diving procedure, it is considered entirely
feasible to flood the tubes from sea and dive without losing
depth control. Such procedure is habitually followed by other
submarines in the Squadron and should be adopted by the POLLACK.

3.
Whereas it is to be regretted the one chance of
inflicting heavy damage resulted in four misses on an enemy
carrier on the night of May 21st, it is considered that the
attack was well conducted and aggressively carried out. The
six attacks with the three inch and .50 cal. machine guns
proves conclusively that submarines have little to fear from
Japanese sampans and large fishing boats. Judicious destruction
of these vessels is a diversion for the crew and is costly to a
nation which depends to a great extent on her fishing industry.

4.
The excellent material condition of the POLLACK
speaks well for the refit received just prior to going on patrol
and for an excellent maintenance routine carried out by the crew
while on patrol.

Subject:        Comments on U.S.S. POLLACK War Patrol.

        1.      This completes the third war patrol for the
POLLACK. All of these patrols were started after the normal
short upkeep period and in each case the ship returned in good
material condition. This speaks well for upkeep and operating
personnel. High speed to and from station shortened the time
on station.

        2.      Seven war heads were seriously pitted as well
as the air flasks and after bodies due to running with tubes
flooded. It is realized that it is desirable to run with tor-
pedo tubes flooded. After much study however, it is believed
that this cannot be done and still expect the torpedoes to per-
form reliably. By copy of this letter commanding officers of
submarines of this squadron are directed not to run with their
torpedo tubes flooded while on patrol.

1. The U.S.S. POLLACK, upon departure on her Fourth
War Patrol, was assigned an Empire area. On 20 October, 1942,
while enroute to this area from Midway, due to the situation
developing in the South Pacific, she was ordered to return to
Midway at best speed, to refuel and then proceed to the South
Pacific. On 26 October, 1942, while enroute to the South Pacific,
the POLLACK was ordered to patrol the approaches to TRUK in an
attempt to intercept crippled enemy ships believed enroute to
TRUK from the Solomons. When it was estimated that sufficient
time had elapsed for crippled enemy ships to reach their bases,
the POLLACK was assigned to the North Section of the TRUK Area.

2. It is disappointing that there were no contacts
and no attacks on this entire patrol.

## The USS Pollack: A Silent Hunter in the Pacific

The USS Pollack (SS-180) was a Porpoise-class submarine, one of the early "fleet boats" of the United States Navy. Commissioned in 1937, she saw extensive service during World War II in the Pacific Theater. Her wartime career was marked by numerous patrols, often in challenging conditions, and she was credited with sinking several Japanese ships.

### Early Career and Pre-War Service

Before the war, Pollack conducted training exercises and patrols in the Pacific, helping to refine the tactics and capabilities of the U.S. submarine force. These early years were crucial for developing the skills and teamwork that would be vital in the coming conflict.

### World War II Patrols

With the outbreak of World War II, Pollack was immediately thrust into combat. She conducted a total of eleven war patrols, operating in various critical areas of the Pacific, including the waters around the Philippines, the East China Sea, and the Truk Atoll.

**Notable Engagements and Challenges:**

*   **First Patrol (December 1941 - January 1942):** Pollack was one of the submarines on patrol when the Japanese attacked Pearl Harbor. She immediately began offensive operations, though early patrols were often hampered by unreliable torpedoes, a problem that plagued the U.S. submarine force in the initial years of the war.
*   **Submarine Warfare in the Pacific:** Pollack's patrols involved long periods of submerged operations, evading Japanese anti-

Subject:          U.S.S. POLLACK - Fourth War Patrol, Comment on.

                  1.      There is good indications from this patrol that
the North Pass to Truck is well guarded by radar. This conten-
tion is borne out by the fact that upon surfacing close to the
Pass on evenings of 10 and 16 November POLLACK was quickly
silhouetted by searchlights. Because of the likelihood of such
radar, POLLACK conducted most of her patrol far enough off
shore to be out of radar range.

                  2.      The material condition of the POLLACK upon her
return from patrol was excellent. The major defect noted was
the noisey operation of the bow and stern planes which were
completely overhauled by the Navy Yard just before departure
on patrol. It is anticipated that the refit will be accomp-
lished during the normal period of two weeks.

                  3.      Health and morale of personnel was excellent and
the Commanding Officer is deserving of credit for the clean,
neat and well cared for appearance his ship presented upon
completion of patrol. The carefully planned training schedule
carried out for both officers and men is commendable and
should bear fruit on future patrols.

1. This command concurs in remarks expressed in enclosures (B) and
(C).

2. The decision of the Commanding Officer to leave his area 15
days early with 44,437 gallons of fuel remaining is considered an error in
judgement. Too much stress cannot be placed on the necessity of all submarines
operating at economical engine speeds so that the maximum time may be spent in
the assigned areas. It must be borne in mind that one of the functions of the
advanced base at Midway is for refueling, and the belief of the Commanding
Officer that Midway would be by-passed was unsound. The POLLACK could have
remained on station an additional ten days.

3. In view of insufficient evidence of damage on attack number two,
the POLLACK is not credited with any damage on that attack. Damage is credited
as follows:

DAMAGED
1 Freighter (LYONS MARU Class) - 7018 tons.

PROLOGUE:
Arrived Submarine Base, Pearl Harbor, T.H. 30 November, 1942,
for refit after patrol of fifty days duration (first refit since
overhaul by Navy Yard, Pearl Harbor).

Major items of work accomplished:

(1) Renewed #3 main motor bearing.
(2) Overhauled auxiliary engine.
(3) Renewed worn gears and realigned pump drive gear
assembly on #2 main engine.
(4) Installed rubber mounting pads and pipe couplings on
trim pump.
(5) Repaired leaky air cooler #2 main generator, installed
spare armature and removed ground in fields caused by
salt water leakage.

Refit was completed by assigned completion date (14 December)
except for #2 main generator. Insulation readings between series
and shunt field coils dropped from 150,000 ohms to 7,000 ohms dur-
ing treatment in place, and on 16 December began removal of gen-
erator through hole cut in pressure hull forward of hard patch.
Washing with fresh water and baking in ovens brought minimum read-
ings to 4 megohms without removal of pole pieces or field windings
from frame. Original armature sent to Navy Yard, Pearl Harbor for
treatment and spare was installed. Repairs completed 25 December.

Training 26-28 December. Fired 3 torpedoes on periscope
approaches, 3 on"SJ" radar approaches, submerged (simulating
night attack by radar, submerged). Also conducted night radar
approaches on surface (no torpedoes fired) and furnished services
to destroyer for sound training on all three days.

Loaded 29-30 December.

2. WEATHER:
    Twenty-six hours after departure from Midway we were forced
    to slow and from this time on until our arrival in the area
    the weather was "fit for neither man nor beast" except
    for one day which seemed to good to be true. The officer
    of the deck's watches were cut to two hours as it would
    have been absolutely impossible to endure more with any
    degree of vigilance. Face masks were tried as protection
    against the driving hail, snow, and sleet but for the
    most part were soon discarded as being much too uncomfort-
    able. During this period sleep was out of the question
    as too much effort was required just to remain in ones
    bunk. All hands experienced the indignity of being thrown
    bodily from bunk to bulkhead at the most unexpected times.
    We arrived in the area exhausted from constant battering
    and lack of sleep.
    During five of the twelve days on station the weather was
    also very bad, with a great deal of snow, sleet, and high
    winds. Surfacing at night with the seas and the reversal
    of course to head back toward the beach was a problem in
    seamanship. When ready to attempt it we would pass the
    word below, "Ready about", which would be the signal for
    all hands to get hold of something secure with one hand
    and hang on to something which might start coasting with
    the other. Even the "Boots" became familiar with the old
    sailing term. The lowest temperature was 23° and while
    in the area the maximum temperature was 36°.

3. TIDAL INFORMATION:
    No radical differences were noted from comments of pre-
    vious patrols in this area except that change of injection
    temperature on 23 January, indicating that we had changed
    from the OYA SHIO into the KURO SHIO was misleading.

4. NAVIGATIONAL AIDS:
    SHIRIYA SAKI and ERIMO SAKI lights were exhibiting normal
    characteristics except for reduced brilliancy. Arc of
    visibility of these lights appears to be all around to
    the seaward instead of as given in the light list. It is
    thought that KAME BAKU light was burning on 26 January
    but it was not positively identified.
    After becoming familiar with the peaks in any locality
    it is safe to approach close in, but it will usually
    take several hours to identify them well enough to be
    sure of positions.

B. ORDNANCE:
(1) Failure of fw'd angle setter. On 21, January while attacking the
large freighter in a night surface attack the forward angle setter failed
to follow the T.D.C. due to excessive binding in the gyro spindles. All
spindles had been withdrawn daily while inboard slugs were fired and had
not been observed to be operating sluggishly. The old ½ H.P. drive motor
which had formerly given sufficient torque had been replaced by a one
H.P. motor so that no difficulty had been expected or experienced in
equally cold water when all spindles were exercised in a battle problem
just prior to entering the area. Each spindle was worked out separately
and all grease connections flushed out with lub oil until all four
spindles turned freely while engaged. The long period of excessive cold
must have caused the grease to harden sufficiently to produce binding.
All angle setters were operated daily throughout the remainder of the
patrol and this procedure will be followed from now on. The commanding
officer feels that the torpedomen should have observed and reported the spindles to
be sluggish and the failure to see and report this was inexcusable.
(2) Failure of #3 and #4 Torpedo Tubes to Fire: During the same attack as
in paragraph (1) an unsuccessful attempt was made to fire #3 and #4
torpedo tubes. They failed to fire either electrically or by hand. Both
torpedoes were partially withdrawn and inboard slugs were fired both
electrically and by hand. The torpedoes were then put back in the tubes
and inboard slugs again fired with the gyro spindles engaged to see if
the binding of the spindles could have been the cause of the failure.
Unfortunately the spindles had been freed in the meantime so that nothing
could be proved since they both withdrew promptly. If the cause were
binding of these spindles why did the top tubes fire? The only answer
seems to be that the lower spindles must have been binding more than the
two upper ones or that the upper tubes were fired twice, however, there was
sufficient evidence to disprove the latter theory.
(3) Hot Run in #5 Torpedo Tube. A faulty stop bolt in this tube permit-
ted the torpedo guide stud to ride under it while the ship was pitching
severely, thus allowing the torpedo to creep forward in the tube, result-
ing in tripping the tripping latch. The torpedo governor tripped and the
torpedo was placed back in commission on 17 January.

C. C.&R.
(1) Negative kingston failed to open on several occasions although the
operating gear functioned normally.
(2) The 600# check valves chattered badly on all deep dives.
(3) #4 M.B. flood does not close in power and is difficult to close by
hand.
(4) #2 periscope fogged up continuously in high power.
(5) The after battery hatch leaked around its flanged joint following
the depth charge attack.

D. COMMUNICATIONS AND RADAR.
(1) Due to the heavy weather all antennae carried away at one time or
another. Several times they were covered by 2-3 inches of ice and this
additional weight was too much.

and four men who have made all five patrols and sixteen men who have
made four patrols. The relief crew plan attempts to solve this problem
but over 50% of the men do not want to go to the relief crew nor do
they want new construction except as a means to get home on leave. In
my opinion great good could be done the war cause, the boat, and morale
at home by permitting the Pollack to spend six weeks enroute to and at
a west coast port. It is very difficult for our men who would like to
remain on the Pollack to see so many of the boats go through Pearl on
their way east while they return time and again to the unnatural
existance in Hawaii.
The performance of duty of officers and men alike under the difficult
conditions imposed by weather, gunfire, and depth charging was most
gratifying. The following named officers are deserving of commendation:

Lieut. A.F. WEINEL, USN, for his excellent work as navigator and for
his assistance and coolness under heavy gunfire during the night
surface attack.

Lieut. J.R. ZULLINGER, USN, for his outstanding performance of duty
as engineering officer and for the excellent depth control at
200-250 feet during the three hour depth charge attack. The trim
pump was used only once and his expert coaching of the planesmen
made it possible to run silent and allude the patrol.

Lieut. A.M. WALES, USNR, who, as Radar Officer, maintained and
repaired the "SJ" radar under the most difficult conditions. He is
not a graduate of the Radar School but has on his own initiative
developed a repair technique which is remarkable.

The following named enlisted men:

B.F. SWICK, S1c, V-6, USNR.
R.O. MAYE, TM.3c, USN.
M.T. CONNOLLY, S2c, V-6, USNR.

are commended for their performance of duty during the night surface
attack. The chase was very exciting, extending over a period of
two hours, during which time they did not relax their vigilance nor
look outside their own sectors - even with shells landing close aboard,
and made no move until ordered to clear the bridge.

1. The Sixth War Patrol of the U.S.S. POLLACK was aggressively
carried out and thorough area coverage was attained. Excellent reconnaissance
information was obtained.

2. It is unfortunate that only three suitable targets were con-
tacted. Much enemy shipping was seen within the lagoon at JALUIT, but ap-
parently was not too active.

3. Of the three possible targets, the POLLACK aggressively carried
out attacks on two, one of which lasted over twelve hours. The attacks were
aggressively made in spite of intensive anti-submarine tactics by the enemy.

4. The Commander Submarine Force, Pacific Fleet, congratulates
the Commanding Officer, Officers, and Crew of the U.S.S. POLLACK for this
aggressive patrol in which they inflicted the following damage to the enemy:

March 27, 1943.
Submerged at dawn 5 miles off the S.W. coast of Jaluit
in very heavy rain squalls and low visibility. Patrolled

     normal approach course but smoke was not seen again.
     A rain squall forming in the area where the smoke was
     first sighted may have been what we thought was the
     smoke.
1923 (M) Surfaced and conducted a thorough search for source of
     smoke but found nothing, then set course for Jaluit.

April 2, 1943
0600 (M) Submerged six miles from the eastern point of Jaluit.
0644 (M) Sighted smoke bearing 267° T. It appeared to be a coal
     burner standing north along the coast, went to battle
     stations, but as we approached closer to the island the
     source of smoke proved to be a steamer anchored or
     moored inside the lagoon near S.E. Pass.
0745 (M) Sighted two float-biplanes circling over the island.
0837 (M) Sighted another steamer inside the lagoon, visible
     through the opening between ENIDJ Island and AINEMAN
     Island. It was close to the reef and appeared to be
     tied up to a dock. Her booms were working and she
     seemed to be unloading.

     catcher type with very high masts and crows nest on
     each.
1205 (M) Soon picked up two small and fast propeller beats and
     we sighted two patrols coming down on us from the north.
     Both were 40 ft. two-masted schooners with sails and
     auxiliary engines. They seemed to suspect our presence
     for they trailed us for an hour in spite of our efforts
     to shake them off.
1258 (M) Sighted a four engine patrol plane to the northward
     and headed right for us at about 2 miles. Went to 120
     feet, stopped evasive machinery, and shook off the
     patrols which had closed us considerably.
     Returned to periscope depth.
1430 (M) During the day we sighted at least 3 float-type bi-
     planes over Jaluit, sometimes singly, but more often
     in 3 plane formation, and they appeared to be practicing
     formation flying and landing.
     Planned to take a position off S.E. Pass tonight in
     order to intercept any steamers coming out during the
     night or early morning. A study of all available data

lagoon. Two were tied up at piers on ENYBOR Island or
to buoys just off the island and about a mile north of
the Pass. The others were anchored inside the lagoon.
there were five or six pairs of masts but it was dif-
ficult to distinguish some of the masts from the trees
and towers on the island. Some of these could have been
patrol boats.

0817 (M) Sighted a float plane landing in the lagoon.
0830 (M) Sighted a four engine patrol plane headed east.
0958 (M) Sighted another float plane headed directly at us so went
to 90 feet for a while.
1043 (M) 3 miles off East Point we sighted smoke bearing
017°T. commenced approach. Smoke turned out to be a
steamer of the KIMISIMA MARU class, 5,193 tons, heavily
laden, painted a dark war color - looking like a naval
auxiliary. Speed was 6.5, knots while zig-zagging
radically and frequently. The plan was a combination
of constant helm and large course changes for short legs.
We were thrown from bow to bow in a most perplexing
manner. Her base course was 180°, speed 14 knots. At
one stage of the approach we found ourselves headed
from her track with a range too small for us to bring
the bow tubes on and the angle too large for much
of hitting. However, she zigged back, not once but
and steamed proudly across our stern at 1,800 yards
range. This was fine as the boys in the after room had
been getting impatient so at
1145 (M) Fired the stern tubes on a 105° port track, gyro angle
3° and 7°, torpedo depth 15 feet. The sea as
usual was flat calm and we knew the planes seen earlier
were probably over us so the periscope exposures were
very short, but one escort was seen on the target's
quarter and headed at her stern as if he were giving
way for us. He may have been standing clear of bomb
as twelve seconds after firing the first torpedo a bomb
exploded very close aboard off the port quarter and had
we been going in for a bow shot it could have easily been
termed a "near miss". This was followed by machine gun
fire. Started deep to avoid more bombs and heard two
torpedo explosions, the targets screws stopped, and
she sounded as if she were breaking up. One torpedo
fired at a point midway between the stern and the bridge,
the other just aft of her stack.

## The Power of Storytelling: Exploring the Impact of Narratives

Storytelling, an art as old as humanity itself, holds an undeniable power to shape our understanding of the world, influence our emotions, and connect us to one another. From ancient myths and folklore to modern novels and films, narratives have always been a fundamental way for humans to make sense of their experiences and transmit knowledge across generations. This essay will delve into the multifaceted impact of storytelling, examining its role in cultural preservation, emotional connection, and the development of empathy and critical thinking.

One of the most significant impacts of storytelling lies in its ability to preserve and transmit culture. Before the advent of written language, stories were the primary means by which societies passed down their history, values, beliefs, and traditions. Oral traditions, such as epic poems, fables, and legends, served as living archives, ensuring that the wisdom and experiences of ancestors were not lost. Even in contemporary society, stories continue to play a crucial role in cultural identity. Family anecdotes, national histories, and community narratives all contribute to a shared understanding of who we are and where we come from. By engaging with these stories, individuals gain a sense of belonging and a deeper appreciation for their heritage.

Beyond cultural preservation, storytelling fosters profound emotional connections. A well-crafted narrative has the capacity to evoke a wide range of emotions, from joy and excitement to sorrow and fear. When we immerse ourselves in a story, we often identify with the characters, experiencing their triumphs and tribulations as if they were our own. This emotional engagement is not merely a passive experience; it can lead to catharsis,

    (a) Evaporators: #1 Electric Evaporator was out of com-
    mission from 15 April on. The compressor discharge pressure
    was high (8-9 lbs.) and the motor tripped out on over-
    load, caused probably by excessive scale. Hours in operation-
    245.

4. COMMUNICATIONS AND SOUND

    (a) The training gear for the upper "JK" sound head carried
    away. This casualty has occurred on two previous patrols.

11. WAS RADIO RECEPTION COMPLETE AND WHAT WERE LAST CONSECUTIVE
    SERIALS SENT AND RECEIVED?

    No. Last consecutive serial sent - No. 5. Last consecutive
    serial received - No. 91.
          There was very poor reception during the entire time
    we were in the area. The new low frequency 16.68 KCS is sub-
    ject to occasional interference by NSS and is also subject to
    fading. Serials 48, 53 and 62 able, were received garbled.
    (the latter being cancelled.) Serials 42 and 46 were received
    garbled and later cancelled after an entire day and night had
    been spent trying to decipher them and in checking the E.C.M.
          The patrol was conducted within the Pearl 2,000 mile
    circle but NQM could never be received on the under-water rec-
    eiving loop while submerged either while on station or on re-
    turn to Midway. Reception on this loop while on the surface
    was good except while on heading 335°T where it usually faded
    completely.
          In transmitting we were unable to get an answer when
    calling NQO on 4235 KCS but could always raise one of the
    Island stations when calling NQO on 4265 KCS. Five (5) mes-
    sages were transmitted in this manner.

          Sound conditions were better than was expected. This
    may be attributed to the excellent work on the part of our
    sound operators who were all certainly on the job twenty-four

U.S.S. POLLACK, Report of Sixth War Patrol - Comment.

1. The Sixth War Patrol of POLLACK covered a period of forty-
three days between departure from Pearl Harbor and return to Midway. Thirty-
two days were spent in patrol areas. Patrol was terminated in accordance with
instructions contained in Operation Order.

2. Comments on Attacks:

ATTACK NO. 1
The chances of hitting on this attack were meager because of
the small track angle and large gyro angle. The first three torpedoes
apparently missed. Loss of depth control prevented observation of the
fourth torpedo, but the time of explosion corresponded closely with length
of torpedo run. The Commanding Officer fully realized that the condition
for this attack were unfavorable, but this was the first target encountered
after almost a week in the area, and the desire to shoot was very keen.

ATTACK NO. 2
This was an extremely well planned and executed attack. Gyro
and track angles were favorable, firing intervals were short and spread
was adequate. Effective counter measures by enemy patrol craft prevented
observation of results, but times of explosions checked with torpedo
runs, and Commanding Officer is certain at least two hits were obtained.
It is felt that the POLLACK was in considerable danger of
being sighted on the surface during the night, in which case the oppor-
tunity for attack might have been lost, but the Commanding Officer
considered the night too bright for a night attack even at radar depth.
In the absence of any positive evidence that there were planes
overhead during this attack, and in view of the shallow depth set on
the torpedoes (8 feet), it is believed that the explosion three hundred
yards off the bow of the POLLACK was a premature rather than an
aircraft bomb. However, the point should not be overlooked that it is
possible to mistake explosions from aircraft bombs for prematures.

ATTACK NO. 3
This was another well executed attack. Here again enemy
counter measures prevented observation of results, but there was every
indication that two hits were obtained.

3. COMMENTS ON MATERIAL. Major defects listed in the patrol
report will be corrected during current refit at Midway, with the possible
exception of noisy bow and stern plane shafting. An effort will be made to
silence the shafting, but no assurance can be given that any great improve-
ment will be effected since this shafting is inherently noisy.

It is believed that the difficulty with jamming of main induction can
be corrected by adjustment of the operating linkage.

While there are no particularly large jobs to be undertaken in
POLLACK during the refit, the overall work load is quite heavy and the full
two weeks will be required to accomplish the refit.

4. The Commanding Officer obtained no comparison between effects
of Torpex and TNT war heads since he was unable to observe any of the torpedo
hits.

5. The anti-submarine activities in the areas patrolled by the
POLLACK were very much in evidence. It is entirely possible that the ships
observed in Jaluit over a period of seven days remained there because they
knew of the presence of the POLLACK in the vicinity.

1. Forwarded.

2. With the possible exception of one premature,
torpedo performance was excellent with a creditable showing
of 50% hits. It is to be regretted that Pollack was driven
deep after each attack and was unable to witness probable
sinkings on her second and third attacks.

3. Having determined the target's speed, base
course and zig-zag plan at 0045 March 21, the commanding
officer should have gone in and delivered his attack. By
waiting until daylight there was a good chance of the enemy
changing the base course just prior to dawn, thereby throw-
ing the Pollack into an unfavorable position for attack.
That this did not occur was fortunate and the attack delivered
at 0702 was well made.

1. The POLLACK's Seventh War Patrol was the first for
the new commanding officer.

2. POLLACK conducted her patrol in an area normally
low in contacts. This patrol proved no exception to the above.
POLLACK, however, carried out good area coverage and was able to
find two good targets, on which she made successful attacks. Both
attacks were aggressively conducted.

3. It is noted that many sailing craft were sighted
throughout the area. It is believed that the enemy is now using
this type of craft to carry provisions and supplies from major
bases to the many outlying islands in the area. Because of this
all sailing craft should be destroyed by gun fire whenever feasible.

4. It is noted that the POLLACK used the SD radar con-
tinuously during the bright moonlight nights. This probably
brought about many of the plane contacts encountered. Several
directives have been issued regarding the possibility of the enemy
DFing our SD radar. The SD radar can be DF'd easily if used in-
discriminately.

5. The Commander Submarine Force, Pacific Fleet, con-
gratulates the Commanding Officer, officers, and crew for this
aggressive and successful patrol. The POLLACK is credited with
having inflicted the following damage upon the enemy:

PROLOGUE:

On April 18, 1943, arrived Midway from Sixth War Patrol.
On April 19, commenced refit by Submarine Base assisted by
Relief Crew of Submarine Division FORTY-FOUR. On April 23,
Lt. Comdr. R.E. PALIER, U.S.N., relieved of command by Lt. Comdr.
B.E. LEWELLEN, U.S.N. May 2, completed refit. May 7, com-
pleted three day training period. Not depermed nor wiped;
no sound tests.

1. NARRATIVE:

May 10
0912(Y) Underway from Submarine Base, Midway for patrol
        area.
0953(Y) Made trim dive off entrance.
1250(Y) Parted company with escort.
2400(Y) Crossed International Date Line and changed time
        and date to 0000(L), May 12, 1943.

May 12-15
        Made training dives and battle surfaces, and held
        fire control drills daily enroute to station. No
        contacts.

May 16
        Entered area; and as we could not make Wet je by
        dawn, decided to reconnoiter Ailuk Atoll.
0610(L) Sighted Ailuk Atoll.
0628(L) Commenced submerged patrol. Intermittent rain
        squalls prevented close observations; however,
        no buildings nor activity were seen.

May 17
0430(L) Dived off Wotje Island and patrolled south and west
        toward Schischmarev Strait. Noted numerous build-
        ings on Wotje, one group of which at the northern
        end of the Island appeared to be hangers or rather
        extensive shops.

0714(L) Sighted trawler type patrol vessel to seaward
          headed toward entrance.
1156(L) Sighted yacht type patrol boat apparently pat-
          rolling entrance to the Strait. Played tag
          with him until
1335(L) Sighted small freighter, similar to TOKATI MARU
          on page 116 of ONI 208-J, standing in toward the
          Strait from the southward.
          Commenced approach but was unable to close range
          to less than 5000 yards. During approach,
          trawler type patrol vessel sighted earlier stood
          in and patrolled very close to entrance. Both
          patrol boats stood in with freighter.
          Closed reef to get a good look inside lagoon.
          The freighter which had just entered steamed
          across the lagoon and anchored off Wotje Island.
          One other small freighter which was painted dark
          red and which had about a ten degree list appeared
          to be aground off the northern tip of ENE
          CHERUTAKKU ISLAND. No other ships were in the
          lagoon.
1846(L) Surfaced and headed for Maloelap Atoll. Was much
          surprised to have noted no air activity at Wotje.

May 18
0336(L) While about 10 miles west off Enijun Channel,
          SJ radar made contact at 11,000 yards; nothing
          in sight. Commenced tracking and found that the
          target was changing course radically, apparently
          patrolling.
0407(L) Made second radar contact at 8300 yards and
          shortly thereafter lost contact on first target
          at 7400 yards.
0420(L) We were challenged by blinker when generated range
          on first target was 4000 yards. Still could not
          see either ship; but as it was commencing to
          get light and we were to the eastward, dived and
          continued approach submerged. Targets proved to
          be the trawler type patrol vessel and the small
          freighter sighted yesterday off Wotje. Again
          was unable to close to firing range. Both vessels
          stood in toward the channel where they were met
          by a yacht type patrol boat. All three vessels
          stood into the lagoon, leaving no patrol outside.

Two radio towers and a very high lookout tower are located on
the southern end of Wotje Island rather than at the point marked
"Radio Station" on the chart.
Three channel buoys are visible from seaward at Enijun Channel.
Two entrance buoys mark the main channel north of Enijun Island; and
one buoy is to the southward of the Island, probably inside the lagoon.
There is some evidence to indicate that Maloelap and Aur Atolls
are about 4 miles to the eastward of their charted positions.
The islands can be sighted through binoculars on a clear, dark
night at about 10 miles.

Subject:     U.S.S. POLLACK - Seventh War Patrol - Comment on.

             1.    This patrol was the seventh for the POLLACK and
the first as commanding officer for Lieutenant Commander Lewellen.
It covered a period of forty-six days of which thirty-three were
spent in the area producing twenty-eight contacts of which five were
suitable torpedo targets. One, the first, contact was most cooper-
ative in that he came back twice. The POLLACK needed three strikes
to hit. It is noted that the POLLACK conducted two successive
patrols in the same area.

             2.    ATTACKS.

                   Both attacks were made from the escort side and a fa-
vorable track angle attained with relatively small gyro angles.
Presence of escort prevented more advantageous firing ranges. All
torpedoes performed normally and five of the seven fired were ob-
served to hit. Spreads used are considered adequate. In the second
attack the fire control organization in which the executive officer
makes the actual periscope observations and the commanding officer
confines himself to conning was employed successfully. This is the
system used to such excellent advantage in the WAHOO. The present
executive officer of the POLLACK was formerly engineering officer of
the WAHOO.

             3.    MATERIAL.

                   The work list is of such length as to make it question-
able whether all items can be completed in the normal refit period.
Every effort will be made to do so. Docking will be required.
POLLACK is scheduled for a navy yard overhaul after the next patrol.

             4.    The experience of unexpected depth bombs during the
afternoon of May 31 demonstrates anew the desirability of going deep
between infrequent periscope observations. It may have been well to
have investigated the possibility of the schooner being equipped
with radio before letting it go on June 11.

Closed the range to 6,000 yards, at which dis-
tance the shapes of the larger ships could just
be made out. It was impossible to identify
them at this range; but they appeared to have
the general outline of large warships. Radar
in the meantime had picked up three more es-
corts on this side of the formation, and an-
other one astern. The nearest one of these
was about 3,000 yards away and closing rapidly.
He seemed to have detected, or at least sus-
pected, our presence as he was opening out in
our direction from the rest of the formation.
We were still too far from the track to com-
mence a submerged approach, so put this fel-
low astern and opened the range again.

Sept. 1
0018(I) Attained position ahead and again started in
for the attack, with much the same result.
We had now picked up a total of eight screen-
ing vessels, and there may have been more. At
least we seemed to get fouled up with one every
time we started in. It was by this time ap-
parent that we were not going to get in on the
surface even though it was a very dark night.
Worked up ahead again and determined to go to
radar depth in time to avoid the screens. Felt
that we had the zig plan pretty well worked out
by this time so at

0120(I) Started in, this time determined to get through
or else. Everything seemed to be going nicely
and we were just getting ready to ease down to
radar depth when the targets zigged radically
away leaving us abeam at about 6,000 yards.
Started in to close the range, but found that in
so doing we were converging a screening destroyer.
Turned out to let him pass with the idea of going
in behind him.

0140(I) When we were 2700 yards abeam of the destroyer
he detected us and turned toward. He must
have picked us up on his sound gear or else he
was equipped with radar, as he could hardly
have seen us at that distance on such a dark
night. Turned away and went to emergency speed,
hoping to lose him in the dark. He apparently
had us spotted, however, as he turned on three
red lights in a vertical row on his foremast and

Sound reported a noise which sounded like an air
leak on board, and the escort appeared to have no
difficulty in staying on us until this noise was
eliminated. Thereafter, he gradually drew away
from him, although he continued to drop an oc-
casional charge, to a total of 17.
2250(I)         Came to radar depth.
2255(I)         Surfaced.
2300(I)         Escort turned on searchlight and swept in our di-
                rection, but beam did not reach us. He must have
                heard us when we speeded up on surfacing. Ap-
                parently he was still guarding our damaged target;
                but we had no torpedoes left, so cleared area.
2311(I)         SJ radar made contact dead astern at 2300 yards.
                Range opened to 2450 yards and contact disappeared.
                Another definite but unexplainable contact.
2340(I)         SJ radar made a series of contacts at ranges of
                500 to 800 yards. This may have been a school of
                whales which had been sighted in the vicinity
                during the afternoon.

Sept. 4
0404(I)         Dived.
1844(I)         Surfaced and proceeded toward Midway.

Sept. 5
0850(I)         Sighted conning tower of submarine through number
                one periscope, bearing 084° T., range 20,000 yards.
                Turned away and commenced tracking. Determined his
                course to be about 180° T., and set course to pass
                out of sight astern of him.
0955(I)         Lost sight of submarine, bearing 164° T.
1032(I)         Sighted same submarine, bearing 195° T. He was now
                on a northeasterly course and gaining bearing on
                us. Either he was patrolling, or had previously
                sighted us and was now trying to work around ahead
                of us.
1057(I)         Dived with the idea of closing him submerged for
                more positive identification.
1337(I)         Having made no further contact with submarine,
                surfaced and headed north. Broadcast contact re-
                port.
1612(K)         Resumed course for Midway.

Sept. 6
2226(K)         Sighted green, three star grenade, bearing 126°T.
                No indication on radar and nothing in sight. Con-
                cluded this must be one of our own subs, probably
                the SEAWOLF.

(C) WEATHER:
The weather in general was excellent except for a number of
calm days on which very careful periscope handling was required.
In the Nanpo Shoto there were two days of glassy calm and four-
teen days on which only small wavelets ruffled the surface. Off
Bungo Suido there were two days of flat calm and six days with
very light air. Low hanging cumulus clouds in amounts four to
ten were usually present throughout the day but these generally
cleared in time to take star sights in the evening. The nights
were generally clear with low hanging clouds around the horizon.
No storms were encountered.

(D) TIDAL INFORMATION:
The current from Midway to longitude 145°E. was in accordance
with the Pilot Chart for July.
In the Nanpo Shoto currents up to one knot were frequently
experienced. East of the line of Islands from the Bayonnaise
Rocks to Sofu Gan the currents were variable but in general set
to the north and northeast. West of the Islands there appeared
to be an eddy from the Kuroshio which curved from an easterly
set in latitude 31°-30N., to south in latitude 30°N., to south-
west in latitude 28°-30N. In latitude 31°-45N., longitude
138°E. a drift of 2.7 knots setting 085°T. was encountered. At
31°-30N., 136°-20E. The drift was 1.6 knots setting 120°T.
Off the Bungo Suido the currents were in accordance with the
Pilot Chart, and as previously reported by other submarines in
this area. Maximum current 2.7 knots was measured. (Note: The
Pilot Chart of the North Pacific for August has on the back of it
a very complete discussion of the Kuroshio).

(E) NAVIGATIONAL AIDS:
Sofu Gan and Tori Shima make excellent landmarks.
Tori Shima sighted at 20 miles on a dark clear night.
Tori Shima was spilling lava out of a central crater on
10 August. The lava was flowing down NE slope into sea. There
was no glow visible at night, however.
The following navigational lights were observed showing nor-
mal characteristics except they all were dimmed:
Ashizuri Saki - Southern tip of Shikoku
Kanai Saki
Okino Shima

1. Start from the top left and move right, then down.
2. Identify headers, column names, and data entries.
3. Pay close attention to numbers, dates, coordinates, and specific naval terms.
4. Maintain line breaks and table structure.
5. Note any unclear text.

Remarks:---Convoy was zig-zagging at intervals of ten to twelve
minutes. Tracking from ahead was most unsatisfactory as it re-
quired from four to six minutes for plot and TDC to detect each
zig, so that it was very difficult to attain a favorable pos-
ition from which to start the approach. Radar bearings were not
sufficiently accurate for good tracking.
It is believed that the fourth torpedo sank and ex-
ploded at a considerable depth close to the submarine. The ship
was swinging when this torpedo was fired, and it was seen to
circle off to the right and the wake disappeared. At almost the
same instant the target was hit, a violent explosion shook the
submarine.

(I) MINES:

     No mines were carried; none were encountered; and no mine
sweeping operations were observed.

(J) ANTI-SUBMARINE MEASURES AND EVASIVE TACTICS:

     The ship resembling the Amagisan Maru was painted haze gray.
The second ship in this same convoy (contact #3) was painted with
a medium pattern camouflage, and was observed to be towing a
heavy cable. This cable was similar to the cable towed by our
mine sweepers except that it was towing much deeper.
     Echo ranging was used by the Nips in all counter attacks,
although in most cases they appeared to have little success with
it and soon gave it up for listening. The DE escorting the
convoy on 3 September (contact #34) was the only vessel en-
countered which used echo ranging in searching. At night, he
used it intermittently prior to our attack, as well as during
his counterattack. The pinging heard on this patrol gave a
sharper note and the individual pings were of shorter duration
than our own or the pinging heard on previous patrols. The
frequency was not accurately determined although the ping-
ing was heard with the receiver amplifier turned to 22 kilo-
cycles.
     There were two "Chidori" torpedo boats patrolling in the
Bungo Suido area which were quite active. There was consider-
able patrol activity, both surface and air, in this locality
whenever ship movements were pending. Depth charges were
dropped either on false contacts or as nuisance charges.
     No air coverage for convoys was encountered in the Nanpo
Shoto area, and air patrols in that area appear to be fairly
light.

(K) MAJOR DEFECTS AND DAMAGE:

     The auxiliary generator armature was placed out of com-
mission after seven days on station due to low insulation read-
ings (100,000 ohms). This armature had twice been flooded with
oil on previous patrols, and the insulation readings have drop-
ped on each successive patrol. The reading was between three
and four thousand ohms at the completion of the last refit.
     Both high pressure air compressors failed during this patrol.
#2 was found to be pumping lub oil in the second and third
stages. It was disassembled but the cause of the difficulty was
not discovered. In the process of reassembly, two fourth stage
rings were broken. No spares were available on board, so it
had to be left out of commission. #1 developed a serious knock

        1.        POLLACK did not average a contact per day of
patrol but the contacts were plentiful and the targets attractive.
The fifty-eight day patrol produced forty contacts from which
five attacks developed. All sixteen torpedoes were fired with
four sure hits and a possible fifth which damaged three freighters
totaling 18,000 tons. There is no positive information to add
to the torpedo performance picture. The Commanding Officer feels
that the terrific explosion felt by the POLLACK in Attack #2
was an erratic torpedo which sank under the ship. The patrol
boats proved troublesome throughout the patrol and the task
force encountered was well screened. On the favorable side of
the luck ledger were the several helpful density layers.

        2.        POLLACK's general material condition is such that
a general overhaul is required. Fifteen months and five patrols
have intervened since last navy yard overhaul. The ship will be
currently refitted and made ready for assignment with the Anti-
Submarine Warfare Training Unit. Following this assignment,
POLLACK should be thoroughly overhauled before making another
patrol. Plans will go ahead to install a Mark III T.D.C.
during the coming overhaul and the question of raising the SJ
will be investigated. It is gratifying to know that the hull
stood 380-feet without any evidence of permanent distortion.

        3.        POLLACK was camouflaged but the Commanding Officer
was unable to draw any definite conclusions as to its efficacy.
He did feel, however, that it was beneficial on the occasion of
crossing 2000 yards dead ahead of an enemy destroyer while
conducting the surface night attack #3.

1. The eighth war patrol of the POLLACK was aggressively conducted
in areas numerous with contacts.

2. All of POLLACK's attacks were tenaciously executed. Enemy anti-
submarine measures prevented observation of final results.

3. The explosion under the POLLACK during the attack on the night
of August 6, 1943, was probably one of POLLACK's own torpedoes exploding at the
end of a circular run.

4. This patrol is considered successful for Combat Insignia award.

5. The Commander Submarine Force, Pacific Fleet, congratulates the

U.S.S. POLLOCK (SS180) - Report of Ninth War Patrol.

(A) PROLOGUE:-
Arrived Submarine Base, Pearl Harbor, on 16 September
1943 from Eighth War Patrol. After a ten day refit by the Submarine
Base, commenced local operations for the Commander Destroyers,
Pacific Fleet, furnishing sound services. From 19 November 1943
to 8 February 1944, overhauled at Navy Yard, Pearl Harbor. The
following major alterations were completed:- lengthened conning
tower, installed Mark 3 TDC in conning tower, relocated SJ and SR
Radar antennas aft periscope shears, installed new SJ-1A Radar
transmitter and PPI, installed TBL-4 transmitter, installed cen-
trifugal trim pump, converted #7 main ballast tank to fuel ball-st
tank, and removed degaussing. From 17 to 24 February conducted
training exercises, which were considerably interrupted by the
necessity for correcting material deficiencies that developed as an
aftermath of the Navy Yard overhaul. Fired six practice torpedoes
and twelve rounds from the four inch gun, which was installed dur-
ing this period to replace the three inch previously mounted. Sound
tested and departed. Due to leaky fuel
ballast tank vent blanks, and for installation of mechanical plane
angle indicators.

(B) NARRATIVE:-

28 Feb
1300(IK) Departed Submarine Base, Pearl, for Midway.

2 Mar
1818(X) Encountered heavy head seas which necessitated slowing.
Flooded out master gyro compass.

3 Mar
1022(Y) Sighted two SBDs which passed within two and one half
miles of POLLOCK without giving any indication of having
sighted her (Plane contact #1). The light colored smoke
floats must be quite effective in those heavy seas.
Arrived Midway and topped off fuel, lub oil and provisions.
Departure delayed by necessity for replacing gyro me-
chanism and air line to #2 impulse bottle.

0545(K) Submerged.
1915(K) Surfaced.
2033(K) Made SJ Radar contact on Safu Can bearing 208 degrees T.,
     range 27,000 yards. Proceeded to check at log which was
     found to be somewhat erratic. It appeared to do fairly
     well if manually deflected each time speed was changed;
     so it was decided to create a new battle station, and we
     now have an official "Pit Log Jiggler".
2310(K) Set course to eastward.

21 Mar.
0045(K) SJ Radar contact bearing 210 degrees T, range 19,000 yards.
     Range closed very rapidly to 13,000 yards and disappeared.
     Believe it to have been a plane (Plane contact #3).

23 Mar.
0030(K) Auxiliary engine back in commission for limited use after
     having completed makeshift repairs. Regular blower removed
     and portable blower rigged to provide air circulation
     through generator.

1050(K) While patrolling on the surface, sighted yellow flare
     bearing 080 degrees T, distance 2500 yards.
1054(K) U.S.S. HALE surfaced on our beam, leaving no fooling very
     small and very foolish, but at the same time extremely
     thankful it was a friend instead of a Jap. Exchanged calls
     with HALE and received message asking if they could help
     us. Judged this to be a bit of sarcasm, but chose not to
     consider it as such and generously invited them to join
     our party on the morrow. They accepted; so gave up
     present search and set course to the westward in company
     with the HALE. Decided to be in position with HALE on
     bearing 240 degrees T, distant 10 miles, by dawn of next
     day, and to remain submerged during the day. Directed
     HALE to use aircraft contact code with indefinite call on
     450 kcs for reporting contacts. Stayed in Radar contact
     with HALE during night.

0316(K) Steadied on course 270 degrees T. and fired two stern
        tubes at second ship in column which was slightly closer
        and which had by this time drawn up and overlapped the
        first target on the starboard quarter.
0317(K) One minute and twenty-five seconds after firing heard one
        torpedo hit followed seven seconds later by another. The
        escort by this time had drawn up fairly close on our star-
        board quarter, so came left to course 220 degrees to put
        him astern.
0328(K) Range 4200 yards to the escort, which appeared to have
        given up the chase and stopped or reversed course. Both
        targets had by this time disappeared from the Radar. Inas-
        much as they had previously appeared as very large pips,
        it is believed they both sank. Commenced reload, which
        again proved to be slow work. Discovered the flask pressure
        on one torpedo to be down to 2000# and that it was imposs-
        ible to get depth on a second.
0443(K) Reload completed. Decided, however, to make no more
        attacks this night for the following reasons: unsatisfactory
        condition of torpedoes, undesirability of making a trim
        dive after having fired ten torpedoes and having used a
        considerable quantity of fuel, proximity of dawn which
        would leave insufficient time for an attack if a trim dive
        was made, the uncertainty as to our geographical position.
        The heavy seas made a daylight submerged approach out of
        the question even if a favorable position for one could have
        been gained in the time remaining before daylight. Retired
        to the northward toward own area.
0535(K) Transmitted contact report on area frequency.
0600(K) Submerged.
26 Mar.
1027(K) While submerged sighted mast bearing 276 degrees T, dis-
        tance 8-9,000 yards (Ship contact #4). Commenced approach.
1111(K) Contact developed into five fishing trawlers, closest range
        7,000 yards.
28-30 Mar. For three days encountered heavy seas, which shifted
        gradually from southwest to northwest. During this period
        it was possible to do little more than ride out the storm.

1921(K) Heard the last of fifty five depth charges and bombs ex-
          ponded on us this date. No damage sustained.
1930(K) Sound picked up light screws bearing 044 degrees T.
1937(K) Sound act of light screws bearing 075 degrees T. Came
          right to bring those bearings abaft the beam.

          sage to NFM and then rebroadcast contact report.
2310(K) Secured transmitting and set course for point of departure
          from area.

4 Apr.
0547(K) Dived and decided to spend the day submerged. Heard several
          distant bombs or depth charges during the day. Wondered if
          some other submarine ran into the hornet's nest we had
          stirred up.
1938(K) Surfaced and set course for Midway.

5 Apr.
1250(K) While cruising on the surface, periscope watch sighted

TARGET DATA-D MAGE INFLICTED

Description:- Attack made on two large AKs in staggered column
             with escort on starboard quarter of second ship.
             These vessels were on the starboard flank, dis-
             tance 2000 yards from the main body of the con-
             voy. Bow tubes were fired at the leading AK.Stern
             tubes were fired at the second AK. The first ship
             either slowed or stopped when hit, and the second
             ship had drawn up on the starboard quarter of the
             first when the stern tubes were fired.

Ships probably Two large unidentified AKs of about 7500 tons.
sunk:-

Damage determined Two hits were heard from the bow tube salvo and
by:- the first target was seen to burn. Two more hits
             from the stern tubes on the second target were
             heard, and five minutes after firing the stern
             tubes, both targets had disappeared from Radar.

TORPEDO ATTACK NUMBER THREE (Continued):-
REMARKS:- Track angles are computed from recordings of ship's
          head, torpedo gyro, and target course.They obvious-
          ly are not in conformity with the spread used.This
          may be due to inaccuracies in recording, as the
          ship was yawing at the time of firing and both the
          ship's head and the gyro angles were changing
          rapidly. It is also possible that the spread was
          incorrectly applied or that the firing bears were
          not correctly matched.

TARGET D.T. - DAMAGE INFLICTED
Description:- Target was an unidentified passenger-freighter of
          about 7,000 tons in convoy with approximately 20
          other AKs. Escorts included two DDs of the FUBUKI
          class. Several aircraft contacts made earlier in
          the day indicated probable air coverage. Contact
          was made by periscope, while patrolling submerged.
          Visibility was good but heavy seas made periscope
          observations difficult.

Ship probably One AK of about 7000 tons.
sunk:-

Damage determined Heard one and possibly two torpedoes hit,
by:- followed by crackling noises of ship breaking
          up, through hull and on sound gear. Approximately
          7 minutes after firing first torpedo, sound re-
          port d four loud but muffled explosions on the
          bearing of the target after which breaking up
          noises ceased.

before being taken aboard. Battery water had been made on board
to replace that which had been previously used, but it had been
carefully tested before being transferred to the battery water
tanks. In any event, however, the casualty was entirely due to a
personnel failure of the men in the tanks was not tested in
accordance with existing instructions before watering was begun.
Since the forward battery appeared to have somewhat the higher
chlorine content, treatment was begun on it first. The electrolyte
in all cells was pumped down to the level of the top of the plates.
Due to repeated failures of the acid pumps, this was not completed
until 0500 on the 12th. The battery was then watered, grounds
cleared and a charge started at 0843. In the meantime, pumping
was commenced on the electrolyte in the after battery. By 1526 there
was no further evidence of chlorine in the forward battery and the
charge was secured. Charge was commenced on the after battery
at 2045, and at 0405 both batteries were placed on charge together
and equalized. As a result of this treatment the chlorine appeared
to have been eliminated from both batteries, although no very con-
clusive tests could be made with the facilities available. Electro-
lyte samples will be forwarded for test immediately upon arrival in
Midway, and gravities will be equalized during the refit period.
At 0100 on 18 March, on starting the auxiliary engine a
loud noise was heard at the generator end of the engine. Inspection
disclosed that the generator blower impeller had struck the casing
with the result that one blade had been torn out of the impeller
and six more had been bent, a piece two feet long had been broken
off of the air guide in the casing and the casing cracked for an
additional two feet and bits of metal which had been gouged out of
the casing had been thrown into the cooler and blown on into the
generator windings. The resistance of the armature windings dropped
from 4 megohms to 150,000 ohms, and could not be improved. A por-
table blower was rigged to provide some ventilation and the genera-
tor was placed back in commission for limited use at 0030 on 23
March. The exact cause of this casualty could not be determined;
but it is suspected that the bolts securing the two halves of the
impeller together worked loose and allowed the impeller to spread
out and strike the blower casing.

tion and frequent tube failures. The wiring and switches in both
units are in extremely poor condition due to breakdown of the in-
sulation and the amount of repair work that has been done on
these units. The wiring and switches in the control unit appear
to be heavy enough to carry the additional load of the PPI
as the heating in these circuits has been sufficient to melt sol-
dered connections. It has been necessary to bypass three fuses
and one power switch in this unit due to failure of these elements.
A PPI unit was also installed during overhaul and proved
extremely valuable in determining target disposition, and also in
staying on the target selected for tracking. Considerable leakage
was experienced around #2 periscope and water was spotted around
in the conning tower. The PPI unit became damp and arcing occurr-
ed in the power supply. The eventual failure of the high voltage
power supply transformer was caused by overloading and surging due
to this arcing. It is necessary that heater resistors be install-
ed in this unit to keep it dry.

(N) SOUND GEAR AND SOUND CONDITIONS:-

Sound gear operation was satisfactory with the exception
of one casualty. On attempting sound communication with the U.S.S.
HALE the CC was discovered to be inoperative. Trouble was locat-
ed in the key contacts and repaired. No attempt was made to es-
tablish sound communication after the trouble was remedied.
Sound conditions were excellent throughout the entire
area. These good conditions can probably be attributed to the
isothermal temperature gradients encountered. Sound picked up
target screws at a maximum distance of seven thousand yards.

(O) DENSITY LAYERS:-

All gradients observed during the entire patrol were
isothermal. This was probably due to the exceedingly rough
weather. The turbulence of the water undoubtedly destroyed any
positive or negative thermal gradient within the POLLACK depth
range. Water temperature was noted to be consistently higher
than atmospheric temperature. During overhaul the Bathythermo-
graph was altered to provide a maximum depth range of 450 feet.

(U) REMARKS:

     During the first control drills enroute to station it was decid-
ed to try using true bearings on the TDC for radar approaches. This
system appeared to have considerable merit and was later successfully
employed on all radar attacks. True bearings were read by the record-
er directly from a true bearing repeater, and the TDC operator match-
ed true instead of relative bearings. This method has the following
advantages:
     (a) The plotters receive true bearings directly without the
necessity of taking the ship's head on each observation and con-
verting relative to true bearings; or the necessity of having an
extra man in the conning tower just to read true bearings.
     (b) It is easier for the TDC operator to match true bearings
than relative bearings when the ship is yawing. This is an advantage
which was not realized until the attacks on the night of 24-25 March
when the ship was yawing badly and the relative bearing dial was
spinning madly.
     (c) It is easier for the TDC operator to note the direction and
rate at which the true bearing is changing, and therefore to more
easily analyze the target movements. This factor is deemed to be by
far the most important benefit gained; and is in itself sufficient
to justify the use of true bearings for radar approaches. The very
location of the true bearing index between own ship and target dials
makes it easier for the operator to visualize the effects of any
bearing change on the set up. In using relative bearings, all but
the most experienced TDC operators are prone to analyze on a basis
solely of corrected versus observed bearing. Although theoretically
this method may give the correct solution, in practice it frequently
results in a wrong analysis and has on more than one occasion caused
the operator to place the POLLACK on the wrong bow of the target. If
the direction and rate of change of true bearing are noted, this
mistake should seldom, if ever, occur.

     There is one disadvantage in using true bearings in that the true
bearings on own ship's dial in the Mark III TDC are hard to read.
The dial is graduated in two degree increments and the index is so
made that considerable parallax exists between the index mark and the

Enroute to station the Pit Log became inoperative. Every
effort was made to get it back in commission, as radar tracking
without this instrument would be of very doubtful accuracy. Shaft
revolutions are of little value in determining speed through the
water, as the speed made good varies considerably with trim and sea
conditions. Reasonably satisfactory repairs were eventually effect-
ed, but the operation of the Log is still somewhat erratic.

Prior to attacks two and three, it was discovered that the
forward TBT was reading inaccurately on certain bearings. The ad-
visability of firing on fixed bearings or on radar bearings was
seriously considered; but after further checking of the TBT, it
was decided that the probable inaccuracy in using it would be at
least no greater than in either of the other two methods. In re-
trospect, it is believed that any attempt to fire on a fixed bear-
ing would have met with complete failure. With the ship yawing as
it did, such a procedure would very distinctly have entailed firing
"on the fly". Neither the Pit Log nor the TBTs is up to the high
standard of quality and accuracy of the rest of our fire control
equipment, and it is strongly recommended that the installation of
the new and improved types be expedited to the utmost.

Prior to departure from Pearl, the POLL CK finally succeeded
in obtaining one of the new mushroom type pressure proof bridge
speakers, which was mounted forward and connected to the 2-MC sys-
tem. It performed beautifully and is now one of our most prized
possessions. The Sperry type speaker which was mounted aft, how-
ever, proved to be completely useless and was a severe handicap in
firing the stern tubes. On those occasions when the stern tubes
were fired, it was necessary for the Commanding Officer to stay on
the forward part of the bridge where he could stay in communication
with the fire control party and the radar, and to relay orders back
to the officer on the TBT. Effective communications between either
end of the bridge and the conning tower are an absolute necessity
for successful night surface attacks and retirement.

developed with skill and daring into very successful attacks.

3. Attack Number One was a night surface attack on
a medium sized AK, or AK with a single small escort. Two tor-
pedoes were fired on a 70° port track, range 2100 yards. One hit
was observed and target was seen to disintegrate in a mass of
flame and disappeared from sight and radar in slightly more than
a minute.

Attack Number Two was a night surface attack
against a DD screening a convoy of some twelve or more ships with
other escorts. Four torpedoes were fired at the destroyer on a
90° starboard track, range 2000 yards. One hit was observed which
resulted in an explosion accompanied by a great shower of sparks
and the destroyer disappeared from sight and radar almost immed-
iately. Three minutes after firing, two more explosions were heard
and a large column of flame was observed on the bearing of the
target but in the main body of the convoy beyond. POLLOCK resumed
tracking after a short retirement, regained position on the convoy
and about two hours later delivered

and set target on fire. Two stern shots at second AK both hit.
POLLACK evaded on surface an approaching escort and both targets
disappeared from radar screen within five minutes.

        Attack Number Four found the POLLACK on submerged
day patrol, with heavy seas running, in the midst of a convoy of
some twenty ships with two FUBIKI type DD's, and other escorts.
With only four torpedoes remaining, POLLACK selected an unident-
ified passenger freighter of about 7000 tons and fired four tor-
pedoes from a range of 1500 yards. One hit was heard through hull
and a second by sound. This was followed by characteristic, unmis-
takable, breaking-up noises. Following four loud but muffled ex-
plosions from the direction of the target, the breaking-up noises
ceased and it is considered that the target sank.

        4.      Torpedo performance was excellent and it is par-
ticularly noticed that at least ten sure torpedo hits were obtain-
ed using depth settings of six feet in relatively heavy seas. The
Commanding Officer's recommendation in regard to taking true bear-
ings from radar and introducing them directly into T.D.C. and plot
for radar approaches appears to have considerable merit and is
worthy of complete investigation.

        5.      The death of E. E. OWEN, torpedoman's mate third
class, as a result of a head injury suffered when struck by a tor-
pedo skid is deeply regretted.

        6.      Health and morale of officers and men upon return
from patrol were excellent. The material condition of the POLLACK
is good and refit will be accomplished in the normal period.

U.S.S. POLLACK(SS180) - Report of Tenth War Patrol.

(A) PROLOGUE:-

Arrived Submarine Base, Midway, on 11 April
from Ninth War Patrol. Refitted by Submarine Base and Relief Crew
of Submarine Division SIXTY ONE. From 29 April to 2 May conducted
training exercises, hampered as usual by uncompleted jobs and post
repair difficulties. Not sound tested and not depermed.

(B) NARRATIVE:-

6 May
1559(Y) Got underway for patrol area and finished assembling
auxiliary generator.
1715(Y) Dived to deep submergence to test main engine exhaust
valve. Test satisfactory. Continued on patrol.
1842(Y) Air escort departed.

9 May
1300(M) Sighted oil drum and held gun drill on same. Drum apparent-
ly contained some oil which caught fire and continued to
burn after drum sank.

13 May
1310(L) In Latitude 29-45.5 N., Longitude 154-22 E., sighted
possible torpedo wake abeam to port, and turned away to
avoid. All hands on the bridge who saw it were positive
that it was a torpedo. However, there were at the time
wind streaks on the water which looked very much like
torpedo wakes. Decided not to send contact report in view
of doubtful circumstances; however, real or not, the inci-
dent certainly served the very useful purpose of keeping
the lookouts on their toes.
2154(L) In Latitude 29-53.1 N., Longitude 152-53.5 E., sighted
green flare to northward, range estimated at 4,000 yards.
This was the proper color for the recognition signal at
the time and the flare looked like one of our comets.

U.S.S. POLLACK(SS180) - Report of Tenth War Patrol.

A light rain now set in, and just an occasional glimpse
of the freighter could be had as he passed in and out
of the rain squalls. He obviously wasn't going any place
and acted very much as if he were searching; although he
appeared to be somewhat larger than the type of merchant-
men that the Japs ordinarily use for A/S work. We were
still playing tag with this fellow among the rain squalls,
when at
0510(I) Sighted a larger freighter similar to the KISYO MARU,
bearing 210 d.T., range 6,000 yards. She was preceded
by a small destroyer which was patrolling station 1500
yards ahead. Both ships were presenting large port
angles, so came to the normal approach course and speeded
up. A zig toward gave us a 30 degree angle on the bow
on the freighter; and it looked for a short time as if
we would get into excellent firing position, until another
zig took us with a long shot. The set up was check-
ing well, however; so decided to shoot.
0530(I) Fired four bow tubes with a run of 3300 yards on a 110
degree port track with torpedoes set to run at 10 feet.
Commenced swinging right to bring the stern tubes to
bear. No hits. At about the time the torpedoes should
have hit, the target was seen to commence turning away,
and dropping depth charges a good 4,000 yards.
It is possible that she maneuvered in time to avoid them;
although it is more probable that they ran under, or
just plain missed. She was seen to be riding quite high
out of the water; but it was decided to use the 10 foot
setting because of the long run. The escort commenced
circling away, and it looked for a time as if we might
be able to avoid him at periscope depth. This hope
lived, however, as he soon steadied up with a zero angle
on the bow and began pouring on the coal. We had our
stern to him by this time, so waited until the range
closed to 1500 yards and at
0540(I) Fired two carefully aimed shots down the throat from the
stern tubes. Went deep without waiting to observe re-
sults, which were not long in coming. A pattern of

0820(I) All clear on sound. Came to periscope depth.
0825(I) Sound reported pinging on the port beam. Shortly there-
        after sighted escort still searching for us. Visibility
        poor due to rain squalls, so eased back down below the
        density layer and put him astern.
0927(I) Back at periscope depth. All clear.

24 May
0050(I) Made contact on SJ radar at 2700 yards ahead, nothing
        in sight (Ship contact #4). While turning away the range
        closed to 1800 yards. Still could see nothing from the
        bridge; so opened out and lost contact at 2600 yards.

25 May
0210(I) Made contact on SJ radar at 9600 yards and commenced
        tracking (Ship contact #5). Tracked target on a steady
        course of 315 d.T. at a speed of 12 knots. The size of
        the pip on radar indicated a fair sized ship so at
        went to battle stations and started in. At 6,000 yards
        sound reported pinging on bearing of the target which could
        just be made out as a dark shape against the horizon at
        this point. By the time the range had closed to 4000 yards
        the target appeared to be quite large (larger than it
        subsequently proved to be), and it was thought that we had
        another destroyer. The steady course and fairly high
        speed indicated that he was going somewhere and not just
        patrolling. At a range of 2000 yards the target was seen
        to have only one stack, and it was apparent that it was
        a destroyer escort or a small mine layer. It was never-
        theless a fair sized ship as indicated by the fact that
        it filled two thirds of the binocular field, or about
        three degrees, at this range. We were, by this time, so
        close that it was felt that we would be detected in
        turning away even if we didn't fire.
0327(I) Fired four bow tubes on an 80 degree starboard track at
        a run of 1400 yards, with torpedoes set to run at six
        feet. The fourth torpedo failed to take the angle and
        ran off to the right; but the first two were seen to
        run directly under the target. No explosion! I don't

        No contact having been made, decided to terminate patrol,
        and set course for Midway. This decision was arrived at
        in view of the fact that we had only two torpedoes re-
        maining, one of which was in poor condition (see
        material defects).

        made radar contact on PBY at eight miles on course east.
        Challenged but received no reply.
1955(Y) Sighted flashing light bearing 060 d.T., probably gun-
        fire from or near Midway.

2 June
0526(Y) Sighted escort planes (2 SBDs) five miles abeam. Had to
        coach planes on to our bearing by radio as they were
        flying on past us.
0836(Y) Moored at Submarine Base, Midway. Found that engine re-
        pairs would cause an undue delay; so decided to continue
        on two engines.

U.S.S. POLLACK (SS180) Torpedo Attack #1 Patrol No. 10
Time:- 0324(I) Date:- 22 May 44 Lat:-28-20 N. Long:138-57E

TARGET DATA - DAMAGE INFLICTED

Description:- Convoy of 6-8 merchant ships, 1 large destroyer,
1 or more smaller destroyers, and several small-
er escorts was contacted by radar at 19,000
yards. Target selected was large destroyer,
probably of the ASASHIO class, which was just
to the left of an 200-300 yards closer than the
first AK. Night was clear and fairly dark, al-
though the visibility was improving rapidly.

Ship sunk:- One ASASHIO class destroyer.

Ship damaged:- One unidentified AK.

Damage determined Saw first of three torpedoes hit destroyer with
by:- a violent explosion. Heard three regularly spac-
ed hits followed by a fourth at a slightly long-
er interval. A second column of smoke indicated
that the AK had also been hit. Destroyer was not
actually seen to sink; but when last seen she
was burning fiercely, and it is believed that she
could not have survived three torpedo hits. The
merchant ship moved on, still smoking heavily.

Target draft:- 9' Course:-320d.T. Speed:- 9 kts. Range:-2900(at
firing)

OWN SHIP DATA
Speed:- 11kts. Course:- 077d.T. Depth:-On surface Angle:-Zero(at

FIRE CONTROL AND TORPEDO DATA
Type attack:- Night surface radar attack. Target was tracked by
relative plot, Navigational Plot and TDC. Due to
approaching daybreak no attempt was made to solve
the zig plan, and the attack was commenced as soon
as target disposition and speed were determined.
Torpedoes were fired using TBT bearings and radar
ranges.

(U) REMARKS:-
        The volume of radio traffic and the amount of decoding
involved continues to increase, and has now reached the point
where it is a real burden. While it is appreciated that the
volume of traffic must be maintained for reasons of security, it
is not being wisely maintained, but constantly increased. During
this patrol, 600 messages were received, or an average of 19 per
day. This compares with an average of four to five messages a
day received a year ago. It has been contended that all submarines
need not completely break down a message when a particular address-
ee is indicated in the text. This is not invariably true as fre-
quently these messages bear a serial number which occasionally
appears near the end of the text. Comsubspac 271101 is cited as a
case in point. Unless this message were completely decoded the
serial number would have been missed and the boat would wonder if
it had missed a message of some importance. It is suggested that
the traffic load can be materially reduced by using different
lists of general calls for boats in widely separated zones. All
the boats which are within the 1000 mile circle of Pearl and the
700 mile circles of Midway and Johnston could be given a separate
set of indefinite calls from those assigned to the boats in the
areas. If a constant volume of traffic were maintained for each
zone, very little traffic analysis could be gained from this
division of traffic.

        Experience has shown ONI 208-J, Revised, to be more diffi-
cult to use than the original issue. From the submarine standpoint,
the features of a ship which are most readily distinguishable
through a periscope are the ones which should be used as a basis
of classification. These are as a rule the stacks and the MFK
arrangement. In the revised issue, the classification according
to "island" structures is most unsatisfactory. It is difficult en-
ough to determine whether or not a freighter has a well or flush
deck without attempting to ascertain whether it has a long or short
midships island or whether a structure aft is a deck house or an
island. Any subdivision of classes by types of sterns is absurd.
By the time the stern can be seen, the situation has arrived at a
point where identification is of purely academic interest.

Number TEN.

1. The TENTH war patrol of the U.S.S. POLLACK was
conducted in the Nanpo Shoto Area and covered a period of
thirty-two days. All but two torpedoes were expended in the
eleven days in the area.

2. Torpedo Attacks.

ATTACK NO. 1 - May 22, 1944

This was a night surface attack against a convoy of
approximately 6 ships and numerous escorts. Of four torpedoes
fired at a destroyer, one hit was seen in destroyer, and another
seen in an AK in a far column. Two additional hits were also
heard to hit at time interval for hits on destroyer. Although
the destroyer was not seen to sink, it was burning fiercely and
it is very doubtful if she could have survived. The merchant
ship was observed to move on smoking heavily.

ATTACK NO. 2 - May 22, 1944

On an submerged periscope attack at daybreak after
attack #1, four torpedoes were fired at a medium sized freighter
at range of 3300 yards. No hits were made either due to excessive
range which had to be excepted from an unfortunate zig away, or the
10 foot depth setting used.

Subject: U.S. POLLACK(SS180) - Report of War Patrol

ATTACK NO. 3 - May 22, 1944

On a down the throat shot on a small destroyer
escorting the ship attacked above, two torpedoes were fired from
stern tubes at range of 1500 yards. Both these torpedoes
missed. It is unfortunate that the POLLACK could only fire two
torpedoes on this shot due to number of tubes aft. The counter
attack following this attack was close and severe.

ATTACK NO. 4 - May 25, 1944

On another night surface attack against a DM or
DE four torpedoes were fired at 1400 yards on 80 degree track.
Two torpedoes were seen to run directly under the target and
not explode. It was lucky for this target that it didnt draw
just a little more water. The fourth torpedo fired was observed
to smoke heavily and take an excessive angle to the right.

3. Materially the POLLACK returned in a fair condition.
Two main engines will be completely overhauled, the other two
routined and defective blowers repaired on all main engines.
Although the auxiliary engine will be repaired and placed in
first class condition, it is felt that this engine should be
replaced as soon as practicable. The refit will be completed
in normal period.

4. The Commanding Officer's points in regard to
radio traffic are well taken. Whether or not his suggestions
could be worked out practically is not known, but it is worthy
of further investigation.

5. The Commanding Officer, Officers and men are
congratulated on this successful and very aggressive patrol.
This was one of the shortest patrols reported for a long time
and it is unfortunate that results against the enemy DD's and
A/S vessels was not more productive. The elimination of at
one large DD was most gratifying. It is recommended that the
POLLACK be credited with inflicting the following damage to
the enemy.

1538(I) Lat. 09d.-12'N; Long. 134d.-01'E (Ship contact #5). Smoke
        and thin hull sighted headed for us bearing 318d.T.
1544(I) Submerged and manned battle stations. Came right to 318d.T.
        Target identified positively as a CHIDORI. He looked as if
        he were searching for our convoy. At about 8000 yards
        range he gave us a large port angle and was showing con-
        siderable bow wave. Clocked him at 15 knots. At 5000
        yards he slowed and gave a 15d. port angle on the bow.
        Believed he had detected us after sighting him. Had plan-
        ned to let him join convoy and make a radar attack before
        moonrise but now I was undetermined. At about 3000 yards
        he zigged right still making a slower speed. When picked
        up, he had been pinging long scale but had stopped ping-
        ing altogether from the 5000 yard look. He emitted large
        puffs of black smoke intermittently. Made bow tubes ready
        and set torpedoes on four feet. Figured we could add some
        data on the running of electric fish at shallow settings.
        Force the sea. Set up showed him on course 145d.T.,
        speed 10 knots and bearings checked nicely.
1627(I) ATTACK NUMBER ONE. Miss. Commenced firing four bow tubes,
        with Mark 18-Mod 1, torpedoes. Torpedo run, 2300 yards;
        104d. port track, gyros averaged 10d. left; depth setting
        four feet. Spread by periscope 1/4 length inside stern,
        1/4 length inside stern, 1/4 length ahead, 1/4 length
        astern. Ten second firing intervals. All misses. Sound
        heard torpedoes running normally and out to target. With
        set-up checking the way it was, believe at least one tor-
        pedo ran under target, more likely two. Remained at peri-
        scope depth with fingers crossed.
1633(I) Heard explosion. Target seemed to be swinging towards us
        so went to 250 feet and rigged for depth charge. Three
        more explosions. Realized these were end of run explo-
        sions. Two people timing got six minutes, and six minutes
        and ten seconds from time of firing for the first explo-
        sion.

1452(I) Lat. 09d.-12'N; Long. 138d.-14'E - (Aircraft Contact #13).
          Sighted by lookout and quartermaster, elevation 3d., range
          7 miles. Plane wheeled and headed toward. Submerged to 140
          feet for 15 minutes then periscope depth.
(1855(I) Surfaced. Prior to today we had crossed off Yap Island. On
          previous strikes no Jap planes and only sporadic a.a. fire
          was noticed. Opposition today was a complete surprise to
          us. Don't believe the Liberators attacked. We stood by to
          chase after downed pilots but no information was received
          over schedules.

12 Aug
0458(I) Submerged, course 030d.T. heading for Yap Island which is
          dead ahead, range 25 miles: No information on strike for
          today but want to be in close to witness bombing if it
          comes off and to reconnoiter. No sign of any strike. We
          were within six miles of the beach but did not notice any-
          thing unusual except that at
1605(I) Saw what appeared to be an explosion near the shore line of
          the island about at the beginning of high land at the sou-
          thern tip of the island. Smoke rose about 300 feet in the
          air and was typical of smoke produced by starting a diesel
          engine in cold climate. Smoke persisted about fifteen
          minutes but we couldn't determine its cause. It didn't
          build up gradually. On one sweep of the scope there was
          nothing and the next, a few seconds later, the smoke was
          present at its maximum persistency, definitely indicating
          an explosion. No noise was heard through the hull.
1902(I) Surfaced with Yap Island bearing 110d.T., distant 10 miles
          by radar.
2100(I) No dope about strike tomorrow, headed toward Ulithi atoll
          and Fais Island.

13 Aug
0925(I) Sighted Big Island (Ulithi Group) bearing 071d.T., distant
          15 miles.
1425(I) Submerged for trim.

U.S.S. POLLACK(SS180) - Report of 7th War Patrol.

2026(I) Radar contact on Fais Island, 17100 yards, bearing 075d.T.
2045(I) Circled island remainder of night.
         No information over schedules regarding air strikes in our
         area for 14 August.

14 Aug
0435(I) With Fais Island bearing 065d.T., range 16,000 yards, sub-
         merged and closed land.
1057(I) At this point we were 2 miles from beach on west side of
         the island.
1058(I) Lat. 09d.-53'N; Long. 140d.-36'E - (Plane contact #14).
         Sighted by periscope. Single B-24 dropped a few light
         bombs on island then made about six tree top strafing runs
         over the phosphate works. Not much damage apparent. His
         bombs appeared to hit in the palm groves.
1606(I) Surface two miles northwest of island.
1608(I) No gun fire from beach, so manned 4" and fired 27 rounds
         of 4"-50 cal. high capacity ammunition at phosphate works,
         concentrating on what appeared to be a conveyor located
         midway in long building on Promontory point. Results were
         gratifying. All but two or three shots were direct hits
         on conveyor or building. Saw some good sized holes put in
         the building and considerable smoke. After 27th shot, gun
         did not fully return to battery so ceased firing and re-
         tired. Realize we are definitely not original in our bom-
         bardment but the plant must still be of military value if
         B-24s hit it. Gun's crew gained excellent experience. No
         return fire from the beach was observed. Our closest range
         was 1350 yards. Noticed single gun on the southwest point
         of the island, partially concealed by trees. Either the
         island has been abandoned by the defense force or the gun
         is a dummy, as it was not trained in our direction. Battle
         surface proved costly, however, as number two engine was
         started with some water in cylinders and the upper crank-
         shaft broke. Number two engine out of commission for
         remainder of patrol. See major defects.

to port or vice versa that there was no doubt that they
were close. At one time we had them bearing from 255d.
around the stern to 145 rel. At this point at least three
of them whipped across our stern. No charges ! Sometimes
I think waiting for them is tougher than having them go
off. Three, possibly four, drew slightly aft and seemed
to be opening. Everyone drew a deep breath only to hear
another one start up. Sound reported his screws were all
over the dial. Men in the Forward Torpedo Room and Crew's
Mess heard his screws through the hull plainly.
1845(I) Lost sound contact on all but one. He was small, pinged
a while then listened. Alternately speeded up and s 1.

1734(I) - Fais still looks unoccupied. Battle surfaced at 3000
          yards range and commenced shelling phosphate plant. Ex-
          pended 50 rounds 4"-50cal., 1200 rounds 50cal. machine
          gun and 180 rounds 20mm. ammunition.
          Fire was slow and deliberate due to lack of opposition.
          Hit the phosphate works consistently at average range of
          850 yards. Smoke of building hindered point of aim so
          shifted to barrack area to right of phosphate plant.
          Direct hits set barrack shack ablaze.
          Shifted back to phosphate plant. Two direct hits on
          end of Promontory Point knocked over loading installation
          and part of cliff, also started fires.

U.S.S. POLLACK(SS180) - Report of Eleventh War Patrol.

SPECIAL REPORT ON MARK EIGHTEEN TORPEDOES

The POLLACK carried a full load of Mark 18-1 torpedoes.
While enroute Majuro from Pearl Harbor, a hydrogen explosion
occurred in the after torpedo in number five tube. As no trouble could
be found with the hydrogen eliminator circuit it was felt that
the explosion was caused by insufficient ventilation and the
following routine was established:-

Ventilate torpedoes for 3 minutes with 200# air every
four hours for twelve hours after charging and every
2 hours thereafter.

Upkeep caused much less trouble than was expected.
Only one torpedo required watering in spite of increased venti-
lation. No torpedoes were shifted. Torpedoes in the tubes
when being charged were secured by a strap around the after guide
stud secured to the roller stanchion.

(I) MINES

No mines were carried, none were encountered, and no
mine sweeping operations were observed.

the oil seal rings were in bad condition. The compressor was
completely overhauled, renewing impellers, timing gears, bearings
and oil seal rings.
In all casualties, the compressors were getting an ade-
quate oil supply and were being operated according to instructions.
Compressor trouble with Kleinschmidt evaporators seems to be fair-
ly common on operating submarines, and since in nearly all cases
the compressors can be put into proper operation by the ship's
force with the material at hand; it is believed that carelessness
or inexperience on the part of the overhaul activities is the
cause of most of the casualties.

Main Engines: On 14 August, number two main engine was
found to be flooded when preparing for a battle surface attack on
Fais Island, the exhaust header drain was found closed, though it
had been opened on the dive that morning. Apparently someone had
later checked it being open and inadvertently turned it the wrong
way and closed it. Indicator cocks were opened immediately and
until no water drained from the indicators. It
was then blown out with starting air. The indicator cocks were
then closed and the engine rolled with air.
The engine jacked by hand, then rolled with air.
It turned freely both ways. Since four engines were desired for
the attack, the engine was again rolled with air and the fuel
racks cut in. A loud noise was heard and the engine secured. A
cracked liner was found on number 7 unit, and a break across #7
crank journal and its web. Some water had apparently remained
in the blower and had been forced into number 7 unit as soon as
the engine built up speed. Personnel are considered to be at
fault, both in flooding the engine and failure to drain the blower
properly before starting the engine.

Auxiliary engine. The auxiliary engine as usual requir-
ed more hours work keeping it running than the engine had hours of
use. In spite of this work, the engine even at its best would not
carry over 100 KW (50% of its rated load) without smoking heavily
and overheating. The main chain stretched excessively and several
times could not be timed without breaking the chain, retiming the
cranks, and removing a link from the chain. Enroute Lajuro, it

of alphabet maze failed causing uncertain stopping of this wheel.
Contractor was cleared and tension adjusted restoring normal opera-
tion. At times stopping mechanism would operate regardless of con-
troller position. The ground causing this could not be located but
reversing the power cord corrected this casualty.

(M) R.D.A.R

During the last refit the SDa radar equipment was re-
placed by an SD-3. The new equipment gave perfect performance with
a minimum of maintenance problems. Usual opening range was 25
miles while one of 40 miles was obtained. Enroute from Pearl Harbor
to Majuro Atoll the starboard whip broke off the mast at the base
of the casting due to a defective casting and whip catching in search-
light power cord when being raised. It is interesting to note that
it was possible to load the broken antenna to about 6 ma. Ranges of
30 miles on some bearings were obtained while on others no results
at all were obtained.

The usual SJ check was made at Pearl during last refit
at which time the magnetron, TR tube, and modulation network were
replaced. During trial runs, indicator unit developed bad horizont-
al displacement. As this unit was in extremely poor condition due
to the amount of maintenance work previously performed and severe
overheating which deteriorated wiring and circuit elements, replace-
ment was highly recommended. Though performance was still not sat-
isfactory, the unit could not be replaced at Pearl for none was
available. Sweep and IF trouble occurred continually while enroute
Pearl to Majuro when the indicator unit was replaced by BUSHNELL.
Shortly after leaving Majuro, sweep developed pulsating
high frequency horizontal oscillation with maximum amplitude of
about 100 yards. This trouble is definitely not in the indicator
unit and is intermittent existing 15 or 30 minutes every two or
three hours during operation. Wide temperature or voltage varia-
tions have no effect on it. Every possible means to remedy this
fault has been tried that would not put equipment out of commission
over too long a period, but still condition persists. This does
not impair normal operation but is irritating when tracking using
the precision sweep and is indicative of possible complete failure.
All other failures were easily repaired and maintenance normal.

Except for one day in area Ten Easy, no enemy planes
were encountered. Also, all anti-aircraft opposition from Yap
that we witnessed was of low intensity. From sightings and
negative information over schedules, it is assumed that during
the month spent on station, none of our planes were shot down
or forced to land in the Yap vicinity. This area is void of
ships, even sampans. Due to the fact that the aviators now have
the situation well in hand, it is considered that lifeguard
missions in the Yap vicinity are now superfluous.

To : The Commander-in-Chief, UNITED STATES FLEET.
Via : The Commander, SEVENTH FLEET.
Subject: U.S.S. POLLACK (SS180) - Report of Eleventh
War Patrol, Comments on.

1. POLLACK's Eleventh War Patrol was spent performing
lifeguard services in the YAP-FALAU area. No opportunities for
rescues were presented.

2. Two unsuccessful torpedo attacks were made on small
craft, torpedoes probably running under targets.

3. Anti-submarine tactics experienced off PALAU on
afternoon of 17 August may indicate the Japs are using some sort
of contact firing charge, as no depth charges were dropped after
repeated runs over the POLLACK.

4. POLLACK twice initiated aggressive bombardments of
the phosphate plant on FAIS Island, scoring numerous hits with
her 4" gun and smaller weapons. Small fires were started and
considerable damage to the installations was probably caused.

5. POLLACK was strafed by a friendly B-24 at 1151I,
August 27, position 09-47.5 N, 138-34.3 E. Fortunately no dam-
age was sustained, and POLLACK avoided by submerging.

6. This patrol is not designated "Successful" for
the award of Combat Insignia.

7. The Task Force Commander congratulates the
POLLACK's Commanding Officer, officers and crew upon completion
of their eleventh war patrol and bombardment of FAIS Island in-
stallations.
