-  During depth charge attack, about 25 minutes after fir­

sound resembling air bubbling through wster. Believe this
heark during that depth charge attack, awd was not heard
during depth charging expuiranced later in fine day. Sub­

For several hours, observed with perilcope two fishing vessels, one of about 250 tons and one of about 300 tons, both of sampan type. Decided to make a battle surface and have target practice for 5 inch, 51 cal. gun crew at sunset. At 18O7, made battle surface and fired first round at 18OO,s opening range about 9500 yards. Gun trained with difficulty, but fired total of twelve rounds of 5" point detonating 111.4 ()0.3) implicitly. At sl:.6; secured gun as it could no longer be trained without the full strength of two men.

No hits were observed, due to long range and training casualty, which was due to self causing the training gear to freeze. Re-occurrence of this casualty will be prevented by exercising training and elevating mechanlmsn every fourth night.

The following system of fire control was used:

0 The Commanding Officer was on the Bridge conning the ship and issuing fire control orders to the Cunnery Officer who was stationed at the gun in supervision of servicing and local control of the gun, and acting as safety officer.

Spotting was done from the Convins JWwe was the fire control center. The Recytive Officer made spots for deflection and range using the perilcope. It was planned to obtain range spots from the SIaED 74 during 1wo hour. all points were collected and the gun range and deflection settings computed by the plotting officer, who was in direct communication with the sight sutter at the gun via battlle telephoncs led through the

Health, Food and Habitability.

In general, the health of personnel was good. The meals were of excellent quality, and the habitability was equivalent to the high standards of other fleet typesubmarines. In connection with habitability, it is interesting to note that the newly installed officers’ bunk room was better ventilated, and provided sleeping accomodations for six officers that were more comfortable, than did the two staterooms and wardrooms which the bunkroom has taken the place of. However, officers, while pleased with the sleeping arrang.e.sent, stated that the stowage facilities, while adequate, was not as convenient and handy.

mention may be extremely important, as, during the recent outbreak of the illness which occurred on October 27, 1943, one man became hysterical. This one case, it is believed, was due to a run-down condition of health of the man concerned.

PERSONNEL:

It is believed that the personnel of this vessel are all trained. Contributing, thereto, is the training received by personnel, during the recent overhaul, at the following schools and training facil[i]ties:

J.T. Radar Operators’ School, NYMI
Night look-out School, NYMI
Summer Training Device, NYMI and NMM. Operating Hospital, 690 acres, Calif.
Marine 10T. Intervention Point,
Coiner Island.

Gyro , NMM.
Distant, First Aid, U.S.N.H.,
Target Area Lost Mask, Calif.
Fire Controller, NYMI.
Attack Tracer, NYMI.

However, it is to the relief of the Corradines that the Torpedo Fire Control Party would have functioned more perfectly if modern Attack Teachers, able to run multiple targets, had been available both at Perry’s Point, California, (century NYMI), 400 feet. Ground manevous Trenchholes have been available, and, of the Understanding Railway Training F-ork which proceeded this coordinated training, tests were made possible by an effective Gamma Spanish path in the Seventh Commander at class,

it was reported by the Torpedo Wing, Survey Officers' School, Philadelphia, that those who were in attendance were attacked and subjected to a maximum fair battle tactics course. Six officers trained on the East. Report the firing of ? training had

It is noted that two attacks were made possible by favorable weather. These were the first Radar attacks made by this vessel. This improvement is attributed to the fact that ships of Undated Passengers would be protected against being scrambled,

RURRYG (Cont).

Lieutenant Award-Ackerman, U.S. Navy, the Executive

Officer of this vessel, acted as the Periscope Officer for
each attack made. In this capacity, he provided the Com-
manding Officer with Information upon which the various
plans for action were based; Through the use of this
torpedo fire control set-up, the Comending Officer was
better able to concentrate on the strategy and tactics of
the attack. In this,con position, it is believed that one
or two hits might have been scored on the Neian Haru, in
addition to those on the Asaka Heru, on the otct of Oct.
over 22, 1943, had this vessel been equipped with a suit
able Night Attack Periscope ana a EP. for the *38R Radar.

**Damage to Own Ship**
None.
Three bombs or depth charges were evidently dropped by a flare of the flare.

Brif framework
Range was excessive to hit such a small target. Use of the periscope was difficult because of heavy sea and sound conditions were very poor. Undoubtedly should not have fired.

TASK GROUP ORGANIZATION

Commender Task Group 17.14
in U.S.S.CERCO (SS225)

Captain C. B. MOISEN

Task Units

17.14.1 U.S. S. CERO (SS225)
- Commanded D. C. WHITE
17.14.2 U.S. S. GRAYBACK (SS208) - Commander J. A. MORE
17.14.3 U. S. S. SHAD (SS235) - Commander E. J. MacGREGOR III

26 September, 1943.

1. The task group was composed of three submarines, task
units 17.14.1, 17.14.2, and 17.14.3.

This unit:              Task Group 17.14.

The next higher echelon:  Task Force 17.

Major Task Force:       U.S. PACIFIC FLEET.

2. The operations of Task Group 17.14 were carried out
in accordance with Commander Submarines, PACIFIC FLEET opera-
tion order #217-43, Serial 001347 of 28 September, 1943.

3. Enclosures (B), (C) and (D) cover the details of the
activities of Task Group 17.14 required by reference (a);
this report will cover only the broader aspects of a "Wolf
Pack" operation.

4. Exercises with convoys to and from Hawaii, with the
helpful cooperation of the Commander Hawaiian Sea Frontier,
were conducted for several weeks prior to the departure of
this Task Group. Cue, two and three submarines operated
with the convoys, attacking singly, in pairs and in groups
of three. It became apparent that three submarines would
be the ideal number to use for a coordinated attack. Two
could not be expected to cover all possibilities and four
would be unwieldy. Until an effective means of employing
and controlling more can be devised, it is quite possible and
to be limited to three. However, it is quite possible and
would be very effective to employ more than one group in the
same general area by keeping them well separated by plan.

5. Using the game board on the wardroom dance floor

at the Submarine Base, problems were set up for groups to
attack single ships and groups of ships. The studies of
these games produced excellent results and a doctrine of
coordinated attack by three submarines was evolved.

6. On 23 September, 1943, the Force Commander (Rear
Admiral 0. Lockswood, jr., USN) authorized a group con-
sisting of the CHRO, SHAD and GRAYBACK. The area assigned
was the East China Sea.

7. The CHRO and GRAYBACK left the Submarine Base, Pearl
Harbor on 26 September for Midway. Enroute various commu-
nication exercises were held and the doctrine was revised
and put into shape. The SHAD joined in Midway and Task
Group 17.14 l return Midway on l October for the Area. Commu-
nication drills were held enroute and a few signals were
added to the list.

8. Cno group was expected to pass west of the
Bonins to and from Tokyo Bay and this Group patrolled
along those routes on 10 October. Submarines were sub-
merged when GRAYBACK made a contact and attacked. The
SHAD received the contact report and althouthvarious ter-
gets were sighted 011 October, no attacks were made.
The signal did not get through to the CHRO. CHRO heard
about twelve depth charges but could not detect the direc-
tion. A depth charge direction indicator would have been
very valuable here .

9. On the night of 11-12 October when proceeding to-
ward area, CHRO made a contact by radar. The Comandino Of-
ficer did not know just where the other two submarines were
and we did not have a grid of this area. No on contact signai
was made. This was a fault in the plan that needed coi
rection. CHRO attacked twice, sinking one ship and damaging
another with four torpedoes. When last seen just before
dark, it was low in the water with a destroyer alongside.

10. All submarines were in assigned squares on the lthi.
and proceeded to hrcassive squares according to the plan.

11. On 14 October GRAYBACK made a contact. Again all
submarines were submerged and signal did not aEt throiugh.

tacks, the escort is free to hold thls one down by a pro

traeted depth chargc attack, leaving his convoy to proceed

unprotected. Mhen more tban one submarine is present, they

cannot afford to do this.

23. tVhen the CERO attack,ked on 12 Oc tober, the destroY

ers spent severa1l hours counter-attacking after each of the

attacks, dropping a large numbr of depth changes (approx

imately sixth-five).

24. tVhen the SHAD attackcd on 27 Oc tober, tbe CERO

28 November, 1943.

Subject: Commander Task Group 17.14 War Diary.

- 7. The recommendations made in paragraph 26 regarding weather fronts is considered worthy of investigation. Such practice has been used by the Germans who were able to give valuable information to their submarines by means of weather stations located in the Arctic regions. If not possible now, our weather central may soon be prepared to furnish submarines with weather front information along the Empire routes such that they can take advantage of these fronts. This will be investigated.

8. By copy of this endorsement the Commander Submarine Force, Pacific Fleet, congratulates the Commander Task Group 17.14, not only for the efficient manner in which this group was organized and maintained, but for the intense study and preparation made prior to his departure.
