U.S. S. HERRING - REPORT OF FIRST WAR PATROL
PERIOD FROM OCTOBER 21 TO NOVEMBER 25, 1942.
AREA CASABLANCA, FRENCH MOROCCO, AND PATROL LINE CAFE
SIM TO MADELRA.
OPERATION ORDER: COMTASK GR THIRTY FOUR POINT ELEVEN
NO. 2-42 dated OCTOBER 15, 1942.

PROLOGUE

HERRING was completed on June 10, 1942 at the
Navy Yard, Portsmouth, N.H., and operated locally in that
area for a period of 3 weeks during which time intensive
training was conducted, including a 5-day WAR PATROL.
Contract torpedo firings were satisfactorily conducted at
Newport, R.I., during the period July 2 - 5, 1942. Training
operations covering another period of three weeks were
completed at New London, Conn., on July 22, 1942. During
this latter period stress was placed on torpedo fire and a
total of ten firings conducted. Immediately prior to
scheduled departure for the Pacific, HERRING was ordered
to Newport, R.I., for special torpedo firings. The period
July 24 to October 3, 1942 was spent at the torpedo station,
Newport, during which time a total of 403 special firings
were conducted. Temporary duty at Newport completed on
October 3, 1942. HERRING returned to New London, Conn., for
upright, routine repairs, and accomplishment of outstanding
alterations incident to becoming a part of Submarine
Squadron Fifty organization. Her work accomplished at
this time consisted of overhaul of ice box interior,
silencing of stern tubes and strut bearings, installation
of SJ and 20-mm equipment, and removal of exterior wiring
and topside fittings.

Throughout the entire period dating from
completion on June 10, 1942 personnel changes were of
a minor nature and the ship's company remained substantially intact.

On October 18, 1942 HERRING reported readiness
for extensive war operations.

1. Took departure from point seven miles east of Montauk Light at 2001 (Q) October 20th, set course for 1st. 39° N., Long. 70° W., zigzagging, speed 12.

October 21 - Submerged running during daylight, 1100 (Q) passed through prescribed point, set course 102° true for 1st. 31° N., Long. 285 W.

October 22 - Submerged running during daylight.

October 23 - Longitude 650 W having been crossed, commenced daylight surface running, zigzag.

October 24, 25, 26 - Uneventful - Conducted daily training dive and torpedo routine.

October 27 - 1142 (P) sighted object resembling conning tower bearing 220° T., distant 6 miles. Dived, changed course to close and went to battle stations. Object no longer visible through periscope. 1215 (P) sighted object bearing 230° T., and changed course to close. 1305(P) identified object either as large run buoys or bow of derelict. At range of 1000 yards object developed to be large run buoys with black and white fairway markings. Took several pictures, and subsequently a possible trap, stood clear submerged for one hour before surfacing in 1st. 34° - 15° N., Long. 430 - 00° W.

October 28, 29 - Uneventful - Conducted daily training dive and torpedo routine.

October 30 - Sighted masts of merchantman at 1307 (O) bearing 150° T., distant 8 miles. Dived. Vessel steering zigzag courses between 305° and 000° T. Went to battle stations and commenced approach. 1348 (O) maneuvered to position for straight bow shot, range 1200 yards, track angle 100° port. Unable to identify. Vessel was about 7500 tons, single stack amidships, two masts, clipper bow, cruiser stern, speed 8 - 9 knots; cargo-passenger type; flush forecastle, small deck house aft with gun; no colors or other identification; starboard deck house aft; in view of (1) uncertainty of nationality, (2) own mission to avoid detection (3) probability of allied or neutral character as indicated by northwesterly course, defensive gun aft, and coloring, decision was made to let him go. Broke off attack, undetected, at 1350 (O) in position 31° - 14° N., 26° - 50° W and resumed course 101° T. 1505 (O) surfaced and went ahead at standard speed 13 knots.

— page 5 —
1. Passed through prescribed point 31° N., 25° W at 0150 (0). Changed base course to 0650 T.
: 2. Crossed 20th meridian at daylight this date, on schedule, and commenced daylight submerging running. 2350 (N) received Admiralty despatch suggesting routing of submarines to clear convoy.
: 3. 0345 (N) received Admiralty despatch directing new route and at 0400 (N) set base course 1040 T. to conform. Held Depth Charge Drills twice daily commencing this date.
: 4. Uneventful - running submerged, periscope patrol, during daylight. On the night of November 4th sighted two white lights on 30-24 watch and maneuvered to avoid.
: 5. Sighted several lights during midwatch, presumably coastal traffic or fishing boats, 0209 (Z) crossed 100 fathom curve at latitude of Casablanca and entered assigned area on schedule. 0550 (Z) submerged on course 090° T. in estimated position 10 miles bearing 330° from AZIMUR POINT light. Fixes for past 24 hours had been unreliable and resort was made to soundings approaching the coast. No navigational charts, lights were distinctly visible at this distance, although within range of AZIMUR POINT light. 0600 (Z) changed course to 030° T., with soundings of 20 - 22 fathoms, in the event position should be to SW of AZIMUR POINT. 0700 (Z) made landfall confirming estimated position, changed course to 070° T. to parallel the coast and identify CASABLANCA before dark. 0922 (Z) changed course to 090° T. to close coast to 20 fathom curve. 1505 (Z) paralleled coast at distance of 4 - 5 miles on course 070° T. 1553 (Z) sighted C. DAR EL BEIDA lighthouse and fixed position accurately at 10 miles bearing 264° from the cape. There are few landmarks along this coast other than a string of tombs, all of which look alike. Changed course to 040° T. 1853 (Z) suffered seven miles of CASABLANCA and had the impression that we had come up in the center of Times Square. The city was lighted up brilliantly except for DAR EL BEIDA light which was extinguished. Illumination to seaward lighthearted every object on the surface.

— page 7 —
1425 (Z) sighted what appeared to be an escort vessel with two submarines in column astern, bearing 100° T., distant about 5 miles, course 270° T. At next observation, twenty minutes later, they were no longer in sight and had apparently turned in to port about the time of first sighting. This was regarded as a routine ship movement from the northeast, or as a possible return from local operations. 1525 (Z) changed course to 090° T. to parallel water-front. 1655 (Z) reversed course. 1755 (Z) changed course to 310° T. to surface well clear of coast after the previous night's experience. Surfaced at 1855 (Z) ten miles from the coast in what was still a disturbing amount of shore illumination. Bearing 2000 T., and not in excess of 1000 yards range, was a well lighted ship, probably a patrol vessel, making slow speed on course about 340°. This should have been sighted through the periscope, although it was not; nor was it picked up on the sound gear before surfacing. Turned tail to him and stood off at high speed on motors. When well clear, and to cover the possibility that we might have been sighted (although there was no indication of it) reversed course and doubled back under his stern, sighting course generally to patrol the CASABLANCA-CAPE MAZAGAN route during the night where we would be reasonably clear of the fishing boats. This track also led the possibility of getting off a shot at darkened coastal shipping; authority to fire at any darkened shipping and on any French man-o-war becoming effective at 2400 (Z) this date. Continuing patrol parallel to coast between CASABLANCA and CAFÉ MAZAGAN. Sighted lighted small craft on two occasions before dawn and maneuvered to avoid. 0440 (Z) DAR EL BINDA light bearing 1350 T. came on showing normal characteristics. 0500 (Z) changed course to 140° T. to close before submerging. 0530 (Z) submerged, changed course to 117° T. heading for a point about one mile north of entrance to reported swept channel. 0802 (Z) sighted two patrol vessels off channel entrance, distant four miles, dead ahead and on reverse of own course.

— page 12 —
1338 (Z) changed course to 250° T. and stood clear at 6 knots. 1445 (Z) slowed to 2.5 knots. 1904 (Z) surfaced, ahead standard speed 15 knots enroute patrol station on CAPE SITI-MADELRA line. Observed single white light on horizon to eastward and intermittent lightning or possibly gunfire from the general direction of CASABLANCA.

November 9 - Uneventful - remained on surface until reaching center of patrol station 40 - 60 miles bearing 235° T. from CAPE SIM. Dived on station at 0530 (N) conducting station patrol at periscope depth. 12 - Uneventful - conducting submerged patrol, periscope depth, during daylight. At 1830 (N) on the night of November 12th made questionable radar contact bearing 240° T. distant 4 1/2 miles. Closed on bearing for four miles but contact was never regained.

November 13 - Uneventful. 0245 (N) received part I of CSS 50 (N)

— page 13 —
15 W. and commenced daylight surface running, course 200° T. speed 15 zigzag. 0630 (N) 0.0.D. sighted coming tower bearing 255° T. distant 5 - 6 miles in Lat. 35° - 25° N. 16° - 25° W. 0.0.D. was quite certain that submarine sighted was one of own class, distinguishable by high periscope sheers above conning tower. When about to challenge him by searchlight at 0640 (N), submarine dive. 0645 (N) changed course 60° to right as precautionary measure, but was convinced that sighting was either GUNNEL or SHAD known to be on same track in about this position. Re-mained on surface transmitting recognition over QC on last observed bearing. No answer received. 0800 (N) resumed base course 2800° T. 2120 (N) crossed 25th parallel at 20° W. Transmitted position and speed of advance on course North to Admiralty.

November 17 - Received U-boat sighting report, originated by GUNNEL, confirming mutuel sighting between GUNNEL and HERRING on previous morning. Since all boats were no north of this point no rectification of the contact appeared advisable.

November 18 - Passed through prescribed point Lat. 45° N., Long. 20° W., at 1000 (N) and set course 0710 T. for point 7 on ROUTE WHITE. Under existing conditions of rough head sea, low ceiling and limited visibility, decided to remain on surface endeavouring to cross ahead of reported convoy as directed. Submerged running would have made this impossible. 2300 (N) received second estimate of convoy position precluding possibility of crossing ahead and indicating that we would pass some 25 miles astern at dawn November 19th.

2. November 19 - Uneventful - submerged running during day-light. No shipping sighted. 2345 (N) passed through point J, set course 0000 T. for point K in Lat. 490 - 02N., Long. 135 - 21W.
3. November 20, 21 - Uneventful - submerged running during day-light. Passed through prescribed point at 2000 (2). November 21st, on schedule, end set course 0600 T. for Lat. 490 - 12N., Long 120 - 55W. 2000 (N) changed course to 0830 T., heading for point 10 miles south of Bishop's Rock, zigzagging in bright moonlight.
4. November 22 - Sighted lights of two small craft at 0220 (N) bearing 0350 T., and changed course to close. At range of 4000 yards identify definitely established not to be U-boats. Resumed base course at 0305 (N), running submerged during daylight.
5. November 23 - 0534 (Z) sighted BISHOPS ROCK light bearing 0230 T. Longitude 8° east having been crossed, resumed daylight surface running. 0820 (Z) sighted WOLFS HEAD light bearing 0230 T. 1203 (Z) sighted escort vessel LA CAPTCHRUSHE accompanied by SIAD and BARD standing out from LIZARD HEAD. Effected rendezvous on schedule and received instructions for passage north. 1312 (Z) ahead at standard speed 15 knots in formation column, open order, following movements of escort vessel. Tested out TBS with ell boats. Darkened ship at sunset.
6. November 24 - Continuing northerly passage through Irish Sea enroute Base II, United Kingdom. Sighted friendly shipping, planes and convoys frequently, Arrived ROTHESAY SOUND, SCOTLAND at 1555 (A) and anchored at 1958 (A).
7. November 25 - 0313 (A) underway from ROTHESAY SOUND, SCOTLAND enroute ROSMARTH BAY, SCOTLAND. 1003 (A) moored starboard side to pier # 3 ROSMARTH BAY, SCOTLAND.

7. Particulars of attacks:

ATTACK NO. TORP. FIRING POINT TRACK DEPTH EST. TORP. EST. RESULT
NO. FIRED INTERVAL AIL ANGLE SETTING DRAFT PERP. SPEED
1 #1 M.O.T. 70(S) 12' 20' H.S.N. 9 Hit
#2 12 Sec. M.O.T. 72(S) 12' 20' H.S.N. 9 Miss

#4 9 Min. M.O.T. 110(S) 12' 20' H.S.N. 9 Hit

Ranges varied from 1200 yards for first torpedo to 1400 yards for fourth torpedo. No. 1 torpedo hit forward of foremast, knocking off part of bow. No. 4 torpedo hit inside stern twisting it upward. Lifeboats manned and lowered. Last observation, preceeded by two detonations, vessel was settled almost to deck line and listed about 30° to starboard; large column black smoke rising above her.

8. Enemy A/S measures: None observed, other than two vessels patrolling off entrance to CASAPLANCA on line of bearing 90° relative, 1000 yards apart. No pinging observed.

9. Enemy mine-sweeping operations: None observed.

10. Major defects experienced:
    a. SJ radar operated only intermittently throughout patrol and required almost constant repair. Lobe-switching feature was inoperative from time of leaving New London, the mast motor being grounded out. It is believed that SJ difficulties were the result of hurried installation and limited test period prior to departure.
    b. TBT on bridge flooded on first day submerged. Inoperative throughout entire patrol.

11. Radio reception: Reception from RUGBY was generally difficult in patrol areas due to excessive static and continual "cracking" noises in receivers. No fading was experienced.

Inability to raise GIBRALTAR on 14 and 15 November is attributed to skip distance phenomenon. Communication with WHITEHALL was established without difficulty on the latter date.

— page 18 —
1. It was found to be impossible to receive
RUGBY schedules while submerged to periscope depth on
patrol stations.

No enemy deception or jamming was observed.

12. Sound conditions and density layers: While
in relatively shallow water sound reception had its usual
erratic characteristics which disappeared after passing
the 50-fathom curve. No density layers were observed.

13. Health and habitability: In general,
excellent, although living conditions were somewhat crowded.

Sick list admissions were as follows:

| NO. | TREATED | DEAGNOSIS | SICK DAYS |
|-----||||
| 1   | D.U. Appendicitis Acute | 6 plus |
| 1   | Burns, 1st & 2nd degree | 6 plus |
| 1   | Cellulitis, left hand | 2 |

14. Miles steamed:
   - Surface: 5621
   - Submerged: 665
   - Total: 6565

15. Fuel oil expended: 54800 gallons.

16. Factors of endurance remaining:
   - TORPEDOES: 20
   - FUEL PROVISIONS: 35,200 gals. 35 days
   - FRESH WATER: 2700 gals. (20,000 Dist. potential)
   - PERSONNEL: 30 days.

17. Factor of endurance causing ending of patrol:
   - None - terminated by order.

— page 19 —
16. Remarks: The number of personnel on board throughout this patrol was considered to be excessive - 6 officers and 66 enlisted men. If at all compatible with the training program, it is recommended that these be limited to a maximum of 6 officers and 60 enlisted men.

It is further recommended that the routing of submarines always be such as to preclude the possibility of interference between boats in water where enemy contacts are probable. Considering the limitations imposed by night navigation, a distance of thirty miles between adjacent positions, enroute is suggested as a reasonable minimum.

1. Narrative:
December 16 - Underway from BASE II, ROSENEAH, SCOTLAND at 1208 (A) in a routine gale, in company with BARB and escort vessel H...s. SARDINYX. Standard speed 15 knots, making passage through IRISH SEA against rough head seas.
December 17 - Continued southerly passage. Exercises scudded with aircraft canceled owing to bad weather and delay in seaplane. Manoeuvered independently when formation became entangled with a large northbound convoy executing a 45° turn. 2400 (A) took departure from point 10 miles south of Bishop's rock, submarine proceeding independently. Set course 253° T on route RLD standard speed 13 knots.
December 18 - From 0015 (A) to 0130 (A) sighted numerous aircraft returning from operations. Some were lighted, others unlit. Practically all released a flare directly ahead of BARB and HARRINGTON. Under existing conditions of bright moonlight some concern was felt regarding the friendly or enemy character of the aircraft. If this is a customary procedure with RAF planes approaching the coast, advance notification would have been helpful. 0713 (A) commenced submerged running during daylight.
December 19 - Uncomfortable - rough head seas made scheduled daily advance of 200 miles impossible but bombing restrictions were sufficiently flexible to cover the delay. 0742 (A) changed course to 180° T., continuing submerged daylight running.
December 20 - 0019 (A) made questionable radar contact bearing 090° T., distance 4000 yards changed course to close but contact was never regained. 0030 (A) resumed base course 180° T., zigzagging. 0729 (A) changed course to 128° T., heading for assigned area.
December 21 - 31 - Uneventful. Intercepted assigned area X.505 off EL FRROL, SPAIN in latitude 43° - 55' N. at 0640 (A) December 21st. Patrolled area submerged during daylight making routine periscope observations while maintaining continuous sound watch. Sighted lighted small craft frequently at night, occasional trawlers and fishing craft to a distance of 20 miles offshore. Practically all shipping sighted moved within territorial waters. Shipping forecasts were used as a check on vessels of appreciable size. There was general conformity, but it was not uncommon to sight lighted shipping making passage along the coast for which no advance information had been received. On subsequent forecasts these movements would be reported, although the information at that time would be of no value. This was a particularly unsatisfactory situation. In the interests of "scrupulously respecting" Spanish neutrality, the presumption had to be made that all lighted shipping

19/3 - Received F.O.K.S. 1512A/31 at 0430 (A) dirigent all submarines to proceed to intercept blockade runner. 0442 (A) set course 302° T., at standard speed 15 knots to comply. Sea moderately rough with strong NW winds. Remained on surface, zigzagging at daylight. 1319 (A) reduced speed to 13 knots with increasing sea and wind. 1341 (A) lookout sighted twin-engine plane on sternboard quarter. Plane had been on parallel course but headed for us a few seconds after sighting. Submerged, continuing to intercept blockade runner. Aircraft released no bombs. 1510 (A) surfaced, all clear, and resumed speed 13 knots. Position circles at this time indicated that there was good probability of intercepting the enemy in about another hour. 1605 (A) sighted U-boat bearing 322° T., distant 4000 yards on approximate course 050° T. Leased vessel U-boat to dive at the same time. Seas were very rough and a periscope observation could be made without broaching only by running in the trough. Endorsed to close U-boat position and hold him by sound but he was not seen or heard again. There was a general feeling of optimism that the blockade runner was nearby and this had been an escort. This optimism was confirmed when, at 1740 (A), unmistakable gunfire was heard through the hull at an estimated distance of 5 - 6 miles. This continued in intermittent bursts for about 5 minutes. At 1750 (A) attempted to look around with about 10 feet of periscope but radius of visibility was not more than 2500 yards under existing sea conditions. Sighted nothing. Estimated position at this time was 45° - 13' N., 110° - 20' E. N. Allowing the periscope a heavy, loud detonation was heard which struck the entire ship. This appeared to come from directly overhead and jarred the sound operator considerably. It was believed to be an aerial bomb and depth was increased to 150 feet. It was also noted at this time that all gunfire had ceased. The sequence of events seemed to indicate that the enemy vessel had either been torpedoed, or had scuttled, yet there remained the possibility of having been bombed.

1946 (a). Received Admiralty despatches at 2200 (a) confirming sinking by U.S.S. SCYLLA. Although it was somewhat disappointing to be in the immediate locality of the action and unable to get off a snort, some consolation was derived from the fact that the aircraft U-boat may have been prevented from getting in at the SCYLLA by being forced down. Set course 1200 T., at 2200 (a) at standard speed 15 knots, returning to assigned area. Passed through general insubility of sinking at 2330 (a) but saw no activity. - Submerged at 0727 (a). Entered assigned area at 2000 (a) and resumed patrol, surfacing at 1937 (a). Received Admiralty despatches on regarding planes with aircrew sightings sweeping 45th parallel during the night. About 2000 (a) received two letter signals on DF frequency, bearing due west. The ship (range in 2-rings, back and forth over a ten degree sector indicated that the plane was reasonably close. 2.55 (a) heard a low-flying plane and saw it pass directly overhead at altitude about 300 feet. Submerged. We were undoubtedly sighted as the phosphorescent wake was very pronounced. - Underway submerged. 0146 (a) surfaced. Heard two-letter signals again on DF frequency on same general westerly bearing. 0153 (a) detected plane on SD radar distance 1/2 mile and submerged again. 0315 (a) surfaced, radar clear, but two letter DF signals continued intermittently. Indications were that one of our own planes was acting as a radio beacon in our area for the planes making the Bay sweep. No information to this effect had been received, if such was the case. January 4 - 10 Uneventful - continuing patrol of area. Two-letter DF signals on 385 kcs were becoming almost a nightly occurrence during this period. In general they appeared to be close aboard and at the western extremity of the area. Activities of fishing boats increased as well and required frequent maneuvering to avoid. Boats operated in groups of four or six and their relatively stationary character suggested the possibility of fishing with drift-lines or nets. The area most frequently used was due North of EL FEHROL and just inside the 100-fathom curve. Shipping movements conformed generally to forecasts subject to previous remarks. Sighted no darkened or suspicious shipping, or any shipping movements outside territorial waters other than occasional trawlers. Most of these were inbound toward PERROL.

from the eastward or northeastward. Shortly before surfacing on January 7, 1945, four more distant explosions similar to those of December 29th.

January 11 - 13 continued patrol of area. During the night of January 13th, made three searches and made radar contact on January 12th and became severe again on January 13th. Upon surfacing on this latter date, the planes could not be rigged in, although tilting operation was normal. Set course 085° T. to run with heavy seas and reduce pounding of planes. Repairs impossible until weather abated. Ran at slow speed during night taking air and occasional water through conning tower hatch. Any other course produced a dangerous pounding condition and lying-to would swamp the bridge. Seas at this time were about 40' high. The protective armor on the 20 mm mount was badly twisted and superstructure noises indicated that some of the superstructure side-plating had broken loose.

January 14 - Submerged at 0600 (A) well in advance of the customer time as it was believed further pounding would result in serious damage. Set course 210° T. to close coast and get a possible ice from PT. LSTAC. to effect repairs. Surfaced at 1945 (A) in a moderately rough sea and decided to attempt repairs using the forward escape trunk as a base of operations with lower hatch closed. Completed renewal of shear pins in about one-half hour, taking aboard several trunks full of water. Bow plane operation again normal. The efforts of Lieutenant H. H. GHEER, Jr., U.S.N., executive officer, C. E. PENNINGTON, CTL(PA) and L. C. CARROLL, LCOLMLU.S.N. are deserving of special mention for their careful planning and expeditious repair work under very unfavorable conditions. Resumed patrol of area at 2100 (A) on general east-west courses about 8 miles North of PT. ESTAC.

January 15 - 16 On the night of January 15th received F.O.V.S. despatch concerning SPICHERN and JACK-LBACHIT no longer being at EL FERROL and directing patrol north of CAPE ORTAGAL. Set course to patrol assigned station although this locality had been under constant patrol previously. Mention of a patrol station by geographical position in a despatcn is not considered the best security. When about to dive at 0730 (A) January 16th made radar contact on a small object slightly forward of starboard beam,

— page 27 —
3000 yards. This locality was then in a
rain squall. Contact moved aft rapidly. Changed
course to bring stern tubes to bear since contact
was now abaft beam, range decreasing. Light
conditions were such that any vessel in the direction
of the contact was at a distinct advantage.
HERRING was out in the clear in early twilight,
whereas the object contacted was concealed by the
darkness of the squall. At a radar range of 1900
yards the JR. O.O.L. reported seeing a small white
wake. This was not confirmed. Dived - shifted to
sound and periscope but contact was never regained.
It is possible the but contact was never regained
or that it was a small unlighted craft. The probable
ability of a U-boat being that far off the normal
route was rather remote. Position: 43°-55'N, 70°-20'W.

January 17 - Received F.O.K.S. despatron at 0100 (A) reporting ALEX LBRECHT as still in EL FERROL and directing HERRING to return to close patrol off that port.
This was the first indication that "close patrol"
of the port had been intended. It appears nowhere
in the patrol orders. The assigned area encompassed
this port, and also covered coastal shipping lanes
over a distance of about 100 miles, and to a distance
of about 35 miles offshore. The area as
assigned had been patrolled constantly within its
limits. The routes selected were those considered
most advantageous to provide both a check on the
movements of neutral traffic, and to intercept any
blockade runners or other enemy traffic further
offshore. This section appeared to cover the intention and OBJECT of the patrol as clearly defined in
F.S.L.I. If close patrol as clearly defined in
it is believed the operation order should now so
stated specifically. There remains some question,
however, of the advisability of restricting a patrol
of this length to the confined waters off a port.
Set course 240° T. to close EL FERROL zigzagging in
bright moonlight visibility 5-6 miles.

January 18 - Continued patrol in general area off FERROL,
closing coast only to such distance as to avoid
detection by various small craft which are frequent
both day and night in close proximity to the coast.
Visibility conditions at night during this period
were very good with bright or partial moonlight
prevailing. It was not uncommon to identify
precinct landmarks from an offshore distance of
10 miles at night. On January 22nd, 23rd and 24th
sea became relatively calm with long southwesters
swell.

1. Continued patrol in eastern portion of area, sea conditions undiminished until forenoon of February 3. On February 2nd received F.O.&S. despatch terminating patrol A... of February 4th and prescribing return route. Set course for southwestern part of area after surfacing on February 3rd preparatory to departure. Signed no suspicious shipping.

February 4: - 1. Departed area submerged at 0800 (A) in Latitude 44° N., on course 2930 T., heading for assigned point on route RED.

February 5: - 6. Continued return pas.sage. At 0245 (A) February 6th received F.O.&S. despatch concerning possible inbound blockade runner and directing HARRING to take patrol station 16° - 05' N., 140 - 15' W. Set course 228° T. at 15 knots to reach assigned station, distant 100 miles. Submerged at dawn, conducting periscope patrol. Surfaced on station at 2000 (A). Signed no shipping. 2315 (A) received F.O.&S. despatch releasing from patrol station and prescribing return route.

February 7: - 9. Resumed northerly passage to rendezvous on route BLUE at 0800 (A) February 7th. Encountered high following seas on the night of February 9th one of which swamped bridge, taking a large quantity of water into conning tower and control room and putting gyro out of co. mission for about six hours.

February 10 - Sighted a large patrol plane at 0605 (A) in Latitude 49° - 44' N, Longitude 70° - 02' W. Plane was flying in low visibility, course about 250° T., and burning a floodlight. At 1150 (A) estimated position by dead reckoning as being at rendezvous point, visibility about 1000 yards - no morning stars obtained, nor landfall on SCILLY ISLES due to heavy mist. Swept with radar contacting escort CUTTYSARK at range of 1800 yards. 1200 (A) proceeded under escort and moored alongside SHAD in FALMOUTH HARBOUR at 1405 (A).

SEVLAN joined formation outside harbor. standard speed 16 knots on various courses concerning to swept channel. 1430 (A) to 1530 (A) rendered services to planes. Extended ship at sunset.
February 12 - Continued passage northwest, 1516 (A) moored at HOSELINE.
2. Weather conditions were not particularly suited to an effective submarine patrol. Average sea conditions were moderately rough with a long swell to complicate depth control. There were few days of relatively calm weather and two occasions storms were encountered with strong winds and high seas. These lasted from three to five days with winds of occasional gale force and seas threatening to swamp the bridge. A cross sea from the southwest generally existed, along with westerly or northwesterly predominating seas. There was a noticeable moderation to the westward of the area both on entering and leaving. This is rough current.
3. Tidal information - Currents, in general, were observed to follow the wind direction and varied from negligible amounts up to 1 or 1 1/4 knots within winds of high intensity. An inshore set was noted when relatively close to the coast and seeking a lee.
4. Navigational aids - All the navigational lights listed in this area show normal undimmed characteristics. PT BETA. Light is occasionally cut off or other but its position is not easily confused with other lights.

During southerly and northerly passages through Irish sea sighted numerous friendly aircraft.

7. Particulars of attack: None.

8. Enemy A/S measures: None observed.

9. Enemy mine-sweeping operations: None observed.

10. Major defects experienced: One blower of a vapor compression still was repaired after seizure, and two spare snare pins were installed in the bow plane rigging mechanism when these became snared in a seaway. Deck lockers in superstructure was badly demolished and set up disturbing noises submerged. These should be more rigidly constructed. Sound needs move become noisy during reversal in train and will be investigated further. All radio antennas have become grounded probably from moisture or leakage into antenna trunk. The SDR radar, covered by separate report, was out of order intermittently. The present state of development of this instrument, and training in its maintenance are still insufficient to provide any great feeling of security in its use.

— page 31 —
1. Radio reception: Very good to excellent throughout the entire patrol. No deception or jamming was observed. Reception with the direction finder loop while submerged was unsuccessful.

: 12. Sound conditions and density layers: Sound reception was generally excellent. No density layers were observed.

: 13. Health and habitability: Health was generally very good. There were several cases of caterpillar fever and two of laryngitis. The long period of submergence resulted in no individual cases causing concern although a general apathy prevailed after about 5 or 6 weeks and occasional absent-mindedness was noted among otherwise reliable individuals. There was a noticeable increase in headaches toward the end of the patrol. Habitability was as good as could be expected in a boat not aired out completely for a long period. Neither temperature nor humidity presented any problems.

18. Remarks -

1. The blockade feature of this patrol, insofar as it concerned the movements of merchant shipping along the coast, was considered to have only a limited effectiveness. Information furnished the commanding officer regarding neutral traffic is subjected to the following criticisms:

(a) Late reports of movements - Commented upon previously in paragraph 1. In a group of five despatches selected at random reporting the movements of 36 ships, 13 of these ships had already passed through the assigned area at the time the despatches were received. An attack on any of these ships over 2500 T., outside territorial waters, would have been authorized by patrol orders - with consequent violation of Spanish neutrality.

(b) Insufficient information - Certain ships were reported by name only, without tonnage, speed or type. Their identity and progress in passage could only be assumed within flexible limits.

(c) Direction of passage - Position reports were received infrequently with no information as to the vessel's destination. The intelligent use of this information is somewhat doubtful.

(d) Lack of descriptive data - No Lloyd's List of Spanish shipping was available. A description of the various types or silouettes of both neutral and enemy vessels should be provided.

(e) Port information - It was only with some difficulty that certain small ports could be located. In at least two instances their locations never were ascertained. Complete Coast Pilots of the Spanish coast, including the Mediterranean should be on board.

(f) Miscellaneous - Weather delays, long voyages and routes with stop-overs enroute introduced intangibles which could only be estimated within wide limits.

2. The duration of the patrol was considered to be excessive. Except for the few hours on the surface during the New Year's day chase, it involved 54 consecutive submerged days avering slightly less than 13 hours each. It is believed that this is a length of time not covered by any previous experience. Autonomy of personnel falls off sharply after 5 or 6 weeks of consecutive submergence and the ability to spend a day or two.

— page 33 —
3. Evaluation of patrol - The commanding officer is of the opinion that the possibilities of a patrol of this sort are hardly sufficient to justify it, and respectfully recommends that further continuance of the present procedure in the light of results achieved and certain features which are both disadvantageous and undesirable to submarine operations. Among these are (1) operating in waters with considerable traffic wherein the probability of a target is remote, (2) limited sea room in the assigned area, (3) operating off the ports of a neutral with neutrality infringement ever a possibility, (4) uncertainty as to the "degree" of neutrality which may be expected, (5) exclusively submarine operations with an incertaine strain on personnel, (6) limited effectiveness of submarine patrol resulting from generally unfavorable sea conditions.

(COPY TO: Commander, U.S.Submarine Squadron 50).

With reference to my signal timed 1602 of 26th February 1943, the Commanding Officer, U.S.Submarine, reports that these D/M signals on 355 M/s. consisted of the letters "D/M", "D/M" or "D/M", followed by a long dash, repeated continuously for periods of half an hour to an hour and followed by a silence for short periods. The letters "D/M" predominate, "D/M" and "D/M" being heard less frequently.

2. The signals were definitely transmitted by hand, no procedure signals were used and no call signs were heard.

3. Except in one case, when the bearing was 100° the bearing of these transmissions was between 230° and 285°, and range and bearing were observed to alter rapidly even during short periods.

4. It is requested that Admiral (Submarines) may be informed of any conclusion that may be reached as to the origin of those signals.

Subject: U.S.S. HERRING - Report of SECOND War Patrol.

1. The report of SECOND WAR PATROL of the HERRING is forwarded herewith. It is well prepared. It was necessary to extend this patrol eight days in order to prevent a gap in coverage of an important port. Thus a planned fifty-day patrol extended into fifty-eight days which proved to be exhausting to personnel because of (1) length of time submerged on station, (2) bad weather, and (3) lack of opportunities for offensive action. Future patrols in this area will be of forty (40) days duration.

2. No damage was inflicted on the enemy as no ships were encountered whose enemy character could be established. The intelligence gained from reconnaissance will be of great value for future patrols in the Bay area, particularly in the event a blockade of the coast is declared.

3. As regards rest and recreation, a hotel near Loch Lomond has been requisitioned for submarine personnel coming off patrols. An officers' club and crew's recreation hall have been set up at the Base and both are now in operation. Approximately half of the crews are sent on leave during each of two leave periods in port. Facilities for recuperation are equal to if not better than those provided for crews of British submarines. The squadron commander is unable to improve the climatic conditions obtaining at the Base, but is of the opinion that conditions are considerably better than those encountered by submarines basing in Alaska. The Commanding Officer, U.S.S. HERRING is reminded that British submarines have been basing in Scotland and Scapa Flow for years and apparently suffer no ill effects. He is also reminded that patrol areas are maintained by Allied submarines in Arctic waters where the rigorous climate is known to be worse than that obtaining in the Bay of Biscay.

4. The repair facilities at the Base are not as adequate as could be desired, but to date the BEAVER force has been able to meet all demands.

5. As has been the case with all patrols in this area, the leak of intelligence on shipping coupled with delays in communicating information of ship movements has imposed a weighty problem on commanding officers. Jane's Fighting Ships and Talbot-Booth's Merchant Ships have been supplied to all submarines. Additional pictures of neutral and enemy merchant shipping are being procured.

6. It appears that the HERRING as well as the other two submarines engaged in the chase for the RHAKOTIS on January 1, was hampered by instructions to dive on plane contact, enemy or otherwise. This occurred five hours before H.M.S. SCYLLA sank the RHAKOTIS at a time and in such a position that the submarines might have been homed on the blockaded runner. By forcing a convoying enemy submarine down in the immediate vicinity, the HERRING contributed indirectly to the successful action and possibly saved H.M.S. SCYLLA from torpedo attack.

7. The creditable performance of duty of Lieutenant H.H. GREER, U.S. Navy, C.E. PENNINGTON, C.T.N.I. (PA), U.S. Navy, and M.D. CARROLL, MOBILE, U.S. Navy, on the night of January 14th is noted.

8. Referring to the remarks in the narrative on January 17th, a close in patrol off EL FERROL was not intended or directed when the HERRING left the Base. Instructions were subsequently changed by F.O.S. dispatches 1923 of January 1, 2254 of January 15, and 1431 of January 16. Unfortunately the HERRING apparently mis-constructed the meaning of the dispatch of January 1.

9. The difficulty experienced in maintaining periscope depth in the sea encountered is noted. When possible, submarines should attempt to time periscope observations with H.S. routines. When sea room on station is available, this can best be done by running in the sea trough. It is strongly recommended that menacing the first H.S. routine at night. Instances have occurred where

U.S. CONFIRMATION - BRITISH SECRET
C-O-N-F-I-D-E-N-T-I-A-L
Subject: U.S.S. HERRING - Report of SECOND War Patrol.

An important message has been sent out during the day and then the message has not been reported until after midnight, thus delaying the submarine several hours in its attempt to intercept a possible target. Submerged reception appears to be quite feasible except in very foul weather when it cannot be relied upon. The use of the D.F. loop for this purpose is considered superior to the fixed loop which method has been tried and discarded because of comparative lack of directional flexibility.

10. The comment of the commanding officer in paragraph 18(a) of his report describes the delicacy of a submarine commanding officer's position while conducting a patrol in this area with the present existing situation.

11. The tactical details noted will be corrected by the tender prior to the HERRING's departure on next patrol.

12. The squadron commander knows that the officers and crew of the HERRING are greatly disappointed in the lack of targets and hopes for better luck on future patrols.

13. Because of the restriction placed on the distribution of U.S. submarine patrol reports by the Commander-in-Chief, U.S. Fleet, it is requested that subordinate commands be furnished with only such extracted information as is considered necessary.

OPERATION ORDER 4-43.

PROLOGUE
The period between patrols, February 12 to March 6, was spent at Base Two in carrying out routine upkeep and repair of certain machinery. This work was accomplished by subplans force assisted by the Tender and eighteen men from the Squadron Training Allowance. Leave and liberty was granted consistent with the work to be accomplished. The Rest Camp at Bucinean Arms was appreciated and used by all officers and a large number of the men. Incident to the transfer of command, a trim drive was made in Loch Long on March 5th, at which time emergency drills were conducted and the crew exercised at bottle stations. Lieutenant Commander JOHN CORBUS, U.S.Navy temporarily relieved Lieutenant Commander R.W. JOHNSON, U.S.Navy on that date in compliance with orders issued by Commander Submarine Squadron Fifty.

1. NARRATIVE.
March 6 Underway at 1300 in company with SHAD for day and night practice runs in the CLYDE Exercise area. Conducted three submerged approaches and four night runs, HNS SKATE acting as target. Anchored in Loch Ranza, Isle of Arran, upon completion of exercises.

March 7 Conducted three submerged approaches, upon the completion of which, cleared exercise area and awaited rendezvous with HNS LA CAPRICIEUSE and SHAD off Garroch Head. Proceeded via swept channel to SCILLY ISLES.

March 8 At 1755 A left escort and proceeded submerged via designated route to patrol area. In view of the large number of planes encountered returning from patrol activities it was decided to proceed submerged during daylight.

March 9 - 12 Proceeded to patrol area, diving by day.

Altered course accordingly.
: 0600 A
Heached patrol station, reduced speed to 15 knots
and commenced surface patrol on a north-south line,
zig zagging with constant helm.
: 0645 A
Love. The decision to patrol station submerged
was based on these assumptions: (1) the enemy had
apparently established air patrols as was evidenced by
the distress message intercepted from the Focke Wulf
200 on the previous day; (2) the target would probably
have an advanced screen of submarines and with the
choppy condition of the sea, detection would be
difficult if not impossible; (3) with unlimited vis-
ibility that prevailed the enemy with lookouts
stationed aloft would have an excellent opportunity
of sighting us and taking avoiding action and (4)
the reported presence of 10 submarines in this general
area in itself was a potential service of information
to the enemy. In order to miss any transmissions,
the high frequency receiver was connected to the
vertical antenna and tuned to the aircraft frequency.
Observations by periscope were made at 15 minute in-
tervals, the boat being brought to a depth of 55 feet,
this allowing 12 feet of periscope to be used, and
thereby insuring a radius of visibility of 3700 yards
to the horizon.

With contact moving in rapidly to four miles
dove and went to 100 feet. It is believed that this
plane was friendly and was conducting a sweep to the
westward in accordance with Cinc Plymouths dispatch
1815 A/17 but no means of verifying this fact existed.
The use of identification pyrotechnics would have
revealed our presence to the enemy if he were in the
vicinity so it was considered wise to dive.

Radar indicated plane at 5 1/2 miles, moving out.
Arrived on station. Commenced patrol in and out
of the moon, running for one half hour in each
direction.
Love and commenced submerged patrol.
Received airplane contact report indicating
blockade runner had passed to the south of us during
the night. It must have been well to the south for
excellent visibility existed and the performance of
the surface radar has been outstanding throughout
this patrol.

Proceeded to patrol area in compliance with Cinc
Plymouths dispatch 0329 A/19, diving by day.
Sighted smoke bearing 0080, commenced approach
but was unable to close target. Since we were in the
"free for all" area hops were high that we might
have an opportunity for some action.
Gave up the chase and resumed course to patrol
area.
Sighted numerous trawlers and small fishing
vessels throughout the remainder of the day and the
night. In most cases these trawlers operate in pairs
and some times in large groups. All are brilliantly
lighted and most of them show Spanish colors.

Entered patrol area. Love at dawn and conducted
submerged patrol in eastern portion of the area.

While patrolling on the surface in Lat. 44° - 13'
N. Long. 08° - 23' W. sighted greenish white flare
sharp on the port bow. Radar obtained contact bearing
328° relative, range 2300 yards. Headed for this point
and range decreased to 1950 yards, but target not
visible. Since we were silhouetted against the moon

Dove.
First heavy explosion occurred, followed in about 15 seconds by a second heavy explosion. The wakes of the torpedoes were obscured through the periscope and the explosions coincided with the arrival at the target. No flash was observed. The depth was set for six feet resulting in a running depth of sixteen feet, which is three feet deeper than the estimated draft. Therefore the explosions (magnetic) occurred undetectable the target. The whole boat shook from the effects of the explosions. The sound operator had picked up sounds on the barring of the target. Servos stopped after the first explosion and this was followed by loud crackling noises. Headed for north-west corner of patrol area (Lat. 44° - 25' N, Long. 090° - 00' W.) since we had not patrolled there previously and we would be as well clear of the scene of attack as it was possible with the area assigned us.

: 0043
Maneuvered to rest off torpedo tracks. Lost sight of target. The presence of numerous trawlers made it inadvisable to search the area for survivors.

: 0234 A
Surface and proceeded at 15 knots to clear scene of attack. Dev. at dawn.

: 1310 A
Decoded POS dispatch 1253 A/21 directing Herring to remain south of Lat. 44° N. and between Longitude 070° - 090° W. Altered course accordingly.

: March 22
Sighted numerous trawlers throughout the day. Decided to conduct patrol in east-north-east of the area since it was possible soon of the large trawlers might well be equipped with sound gear and our periscope was known. Because of the large number of trawlers it was impossible to have eastward until 2345.

— page 50 —
0215 A
Signed bright yellow flare bearing North. Since moon was silhouetting us,dove and headed north. Nothing heard on sound equipment. This may have been an airplane flare since it was higher, brighter and stayed burning longer than the flare sighted on the 21st. No contact obtained on the surface radar and nothing could be seen with glasses.

: 0320 A
Surfaced and proceeded eastward. Decoded FOS dispatched 2334 A/22 indicating the possibility of 3 small and 4 medium sized cargo ships escorted by 3 destroyers are proceeding along the north coast of Spain, and directing herring to proceed and patrol in the vicinity of Lat. 43° - 20' N. Long. 110° - W. Proceeded at 17.5 knots

: 0600 A
Love and proceeded submerged. The close proximity to EL FERROL and the numerous fishing vessels made diving at dawn a necessity. Weather became overcast during the day and seas increased from southwest.

: 2130 A
Surfaced in heavy sea. Barometer had dropped one inch during the day. Proceeded at 15 knots to patrol station. Ship pounded so heavily that it was necessary to reduce speed to 12 knots.

: March 24
Reached patrol station. Forty foot waves were running from south southwest along with a nasty cross chop. Love at dawn.

: March 24 - 26
Conducted submerged patrol - uneventful.

: March 26
Surfaced and proceeded in accordance with FOS dispatch 1533 A/26 to patrol in the vicinity of Lat. 43° - 10' N. Long 090 - 50' W.

: March 27
Sighted two yellow flares on the port beam, estimated distance 2 miles. These flares were of a different type than previously sighted, having the appearance of being suspended by a parachute. Radar could make no contact and nothing was seen on the surface. In view of the reported increased enemy air activity in this general area considered it wise to dive. Proceeded submerged towards estimated position of flares but could hear nothing on the sound equipment.

: 0240 A
Surfaced and proceeded towards patrol station.

0440 A
Picked up homing signals on 395 KCS. Station used call sign 7 U 7. Bearings changed from 025° to 036°. Signals continued until morning dive.
: 0530 A
Reached patrol station and dove at dawn. Conducted submerged patrol.
: 1015 A
Sighted unidentified single engineed low winged monoplane flying at high speed close to the water on course 270°. Sea was glassy with long swell from the northwest. The officer at the periscope is certain it was a fighter plane. The plane was not close enough to observe markings and because of the smooth sea no time was wasted in going deep.
: 2136 A
Surfaced and proceeded in accordance with FOS dispatch 1931 A/27 to patrol in the vicinity of Lat. 44° - 12' N. Long. 11° - 50' W. Was informed of the possibility that three blockader runners escorted by three destroyers, seven torpedo boats and one submarine had sailed from BORDEAUX on the 25th or 26th for Japan.

March 28
0237 A
Homing signals received on 395 KCS. Station used call sign 7 P 7 on this occasion. Bearing of signals varied between 017.5 to 040° and changed rapidly at times. Signals continued until we dove at 0510.
: 0443 A
Radar indicated plane at 10 miles but contact was lost in about 6 minutes.
: 0500 A
Radar indicated plane at 5 miles. It closed to 4 miles and remained constant for about 3 minutes and then opened to 6 miles. This must have been a large plane for the "pip" was fully two inches high. Lost contact at 0505.
: 0509 A
Sighted yellow flare broad on the port quarter, estimated distance 3000 yards. It was the same type of flare sighted the previous night. No contact on the surface radar and nothing could be seen, altho it was bright moonlight in that direction. Dove and headed for position where flare was seen. Nothing on the sound equipment.

March 28 - 29 Conducting submerged patrol - uneventful.
March 29 - 0240-0415A Heard homing signals using call sign 7 X 7 on 395 KCS. Bearing between 021° - 0490.
: 2300 A
Decoded FOS dispatch 2229 A/29 reporting German merchantmen escorted by five destroyers in Lat. 45° - 50' N. Long. 06° - 22' W., course 250, speed probably 12 knots and directing herring to proceed to a new patrol station in Lat. 44° - 46' N. Long 11° - 50' W. Altered course accordingly. Our new station puts us 20 miles to the north of the enemy track.

— page 52 —
0310 A
Received FOS dispatch 2318 A/29 correcting enemy's course to 225° and giving a description of the blockade runner. New enemy course passes still further to the south of our assigned station.

: 0115 - 0355 A
Heard homing signal on 395 KCS. using call sign 7 N 7 bearing between 0270 - 0790.

: 0500 A
Recaced patrol station. Dove at dawn and patrolled a north-south line.

: 1230 A
Decoded FOS dispatch 1142 A/30 reporting four destroyers at 1040 in Lat. 44° - 10' N., Long. 130° - 01' W., course 250°, speed 12 knots and directing submarines to remain on station. Destroyers were well to the south and west of us.

: 1305 A
Decoded FOS dispatch 1228 A/30 reporting one merchantship at 0945 in Lat. 45° - 20' N., Long. 100° - 05' W., course 250°, speed 11 knots. .e. should easily intercept this ship if the information is correct.

: 1345 A
Commenced shifting patrol station twenty miles in the direction 070° to insure interception of reported merchantmen during daylight in compliance with FOS dispatch 1239 A/30.

: 1410 A
Decoded FOS dispatch 1333 A/30 reporting another merchant ship at 1220 in Lat. 44° - 25' N., Long. 110° - 04' W., course 225°, speed 12 knots, probably the TANNENFELS. This ship was to the south and east of us and could not be intercepted submerged.

: 1518 A
Stopped advancing patrol station in accordance with FOS dispatch 1348 A/30. Was informed that two ships previously reported were considered one and the same ship and that she was probably in Lat. 44° - 25' N., Long. 110° - 04' W., course 225°, speed 12 knots at 1220. If surface patrol at 18 knots was conducted it would be possible to intercept at 2240 a but it would involve passing in the proximity of one of our own submarines. Decided to maintain patrol station.

: 2000 A
No schedule received from Rugby on 16 KCS. Shifted to Whitehall on 51.5 KCS but unable to receive this station submerged since our coupling unit covers the bands 15 to 35 KCS.

: 2145 A
Surfaced and upon decoding FOS dispatch 1936 A/30 proceeded to new patrol station in Lat. 44° - 30' N., Long. 100° - 55' W. Was advised of the possibility of encountering the German destroyers during the night. Keen concern was felt for the close proximity of the two friendly submarines. Overcast weather and unpredictable currents in this area do not make for accurate navigation.

— page 53 —
0600 A
Dove and conducted submerged patrol. Large
swells from the northwest made a periscope patrol
difficult. The H.S. routines are apparently still
being broadcast on 51.5 KGS from Whitehall. Unable
to receive on this frequency.
1742 A
Sighted two trawlers in Lat. 44° - 38' N., Long.
10° - 50' W. They placed about 300 tons, were
equipped with radio and were proceeding on various
courses. Approached to within 1200 yards but could
see no colors. Decided against attacking them since
it would be impossible to sink both of them before they
could report our presence by radio and divert any
blockade runners from own vicinity. It had not been
possible to receive any of the H.S. schedules through-
out the day and it was still hoped that an opportunity
would present itself for an attack. It was with great
regret that these trawlers were allowed to go unattack-
ed but we were hoping for bigger game.
2150 A
Surfaced and proceeded to patrol area K505 in
compliance with FOS dispatch 2007 4/31.

2. WEATHER

The weather in general was excellent. One storm was experienced but lasted only forty-eight hours. Heavy fog was encountered in the patrol area during the night of 4-5 April.

: 3. TIDAL INFORMATION

Ocean currents are strong and variable in the Bay of Biscay. Wind has a pronounced effect, causing currents to run from about 200 to the right of the direction from which the wind is blowing.

: 4. NAVIGATION AID AID

All navigational aids on the Spanish Coast bordering the patrol area are in operation. Point Estaca light appears to be dimmed at times and its period is 53 seconds.

: 5. ENEMY WARSHIPS AND MERCHANTMEN SIGHTED

None were sighted aside from the U-boat on the morning of March 21st. Only the forward gun on the U-boat was observed. The usual low box like conning tower was very plain.

: 6. DESCRIPTION OF AIR CRAFT SIGHTED

| DATE & TIME | LOCATION | DESCRIPTION |
||||
| March 15 - 0930 A | Lat. 43°-59' N. Long. 07°-20' W. | Twin engined bombing plane, course 090° flying close to the water. |
| March 16 - 1202 A | Lat. 44°-10' N. Long. 09°-20' W | Twin engined bombing plane, course 270° flying at about 1000 feet. |
| March 27 - 1015 A | Lat. 43°-10' N. Long. 09°-50' W. | Single engined, low winged monoplane, course 270° flying at high speed close to the water. |

None observed.

10. MAJOR DEFECTS EXPERIENCED.
1. NO. THREE MAIN ENGINE.
While surfacing in a rough sea on March 23rd. No. three main engine was flooded while attempting to start it. The liner on # 9 cylinder was cracked and was replaced by ship's force. This casualty was the fault of operating personnel and not of material.

2. SOUND EQUIPMENT.
The sound heads became very noisy in training. It is believed the lignum vitae bearing has become swollen and is binding the shaft supporting the head. The QB head became so noisy that its use was discontinued.

3. RADIO DIRECTION FINLER LOOP.
The radio direction finder loop became very stiff in train during the first part of the patrol. It is believed that repacking will correct this condition altno misalignment may exist.

4. NO. TWO VAPOR STILL COMPRESSOR UNIT.
The packing around the shaft of the compressor unit continued to give trouble. Inspection revealed indications of misalignment. New packing and springs will be required. Temporary repairs were effected by ship's force using high pressure packing and strips of leather.

5. DEGAUSSING EQUIPMENT.
The insulation on the armature of the motor generator supplying current to the M coil broke down resulting in shorted coils. Attempts were made to short out these coils but too many coils were damaged and this method was abandoned. The armature of the motor generator supplying the F coil was used to replace the damaged armature and current for the F coil was supplied by the battery charging panel. The shifting of the armatures, weighing about 700 pounds, while underway, provided a problem in rigging. Lieutenant R. BUDD, USN., is deserving of special credit for the ingenuity and perseverance demonstrated in this particular instance.

— page 56 —
11. RADIO RECEPTION

Radio reception on 16 KC from Rugby, both surface and submerged, was excellent. Perhaps between 62 and 65 feet were necessary to insure good reception while submerged. It was impossible to receive Whitehall on 51.5 KC on the loop while submerged since the coupling unit covers the band between 15 and 35 KCS.

The one message transmitted on March 31st was cleared without difficulty on the ship to shore frequency.

It is strongly recommended that a traffic summary list precede all routines. This list should include the delivery groups, precedence and group count. Such a summary would preclude the necessity of spending long periods at periscope depth which is sometimes difficult to maintain.

It is unfortunate that both MS and HS messages must be broadcast on the same routine and with the idea of reducing the time at periscope depth it is suggested that Immediate and Important messages be sent as the first part of the HS and MS broadcasts. This should apply even though such messages have already been previously transmitted.

12. SOUND CONDITIONS AND DENSITY LAYERS.

In general sound conditions along the northern Spanish coast are poor. Trawler screws were usually picked up at 5000 yards although not always. Better performance of the equipment should be expected under normal conditions.

Every imaginable type of noise was heard in the area, ranging from high pitched squeak to deep rumblings. No explanation can be offered and all of it cannot be laid to fish although large numbers of them were observed at night. The water noises became so bad at times that screw noises were drowned out at 1000 yards.

Numerous heavy explosions were heard throughout the patrol. Some of the se explosions were heavy enough to shake the conning tower and to get all hands out of their bunks. Search by periscope revealed nothing in the vicinity. It was thought that fishermen might be using dynamite or that construction work was underway on the Spanish Coast but these are merely surmise. In most instances fishermen were not in the vicinity when the explosion occurred.

— page 57 —
13. HEALTH AND HABITABILITY

The health of the crew was excellent. An epidemic of colds occurred after departure but it is believed that it can be attributed to the weather rather than anything else. The damp raw weather of this area is not conducive to the prompt cure of colds. The air conditioning units were used throughout the patrol and greatly improved the habitability of the boat. At the end of fifteen hours the CO2 content was slightly less than two percent. By using the 200 pound air compressor pressure in the boat rarely exceeded one inch.

The heavy meal was served at midnight with breakfast at 0700 and a comparatively light supper at 1800. This reduced the amount of cooking required while submerged to a minimum.

18. REMARKS
The patrol was disappointing in that no opportunity presented itself to attack the enemy aside from the encounter with the U-boat on the morning of March 21st. In this attack Lieutenant H.E. DAVIS, U.S.Iavy was officer of the deck and handled the situation in a most creditable manner. The Commanding Officer must depend on the officer of the deck to take decisive action in night attacks.

Information of the prospective movements of Spanish shipping was of little value. Until such time as the present information is supplemented with the time of departure, route to be followed and the expected speed of advance, it will continue to be of small value. All Spanish ships encountered were well lighted and bore the accepted neutrality markings. As a general principle it was decided to attack all tankers and all merchantmen over 2500 tons that were making 15 knots or more unless definite information indicated that such a ship might be expected in the area.

The quality and quantity of the food was excellent. The menu was varied and tasteful.

    (Paragraph 7 of Report).

1. The report of the THIRD War Patrol of the HERRING is
   forwarded herewith. The duration of the patrol was thirty-seven
   days of which twenty-three were spent on station.

2. The material co dition of the submarine upon return
   from patrol was excellent.

3. Although this was the third war patrol of the HERRING,
   it was the first under this command for the commander of the
   Lieutenant Commander Corbus is congratulated on the alert, agrees-
   sive action fought by his ship on the night of March 21st, which
   resulted in the sinking of a German U-boat. It is probable that
   the HERRING was sighted first and was challenged, but due to prompt
   and efficient use of radar and torpedo fire control equipment, she
   turned the tables on the enemy.

4. A well done to the commander of the HERRING, and
   crew of the HERRING, who are believed to have inflicted the follow-
   ing damage on the enemy:

Sunk - 1 530-ton German U-boat.

A recommendation on awards will be made the subject of separate
correspondence and will be subject to the decision of the Assess-
ment Board.

1. Subject patrol report was forwarded by reference (a), with the comments of third command.

2. The comments of Admiral (S) are contained in Enclosure (A) and (B). Attention is invited to his opinion, expressed therein, that the U-boat attack was most ably carried out and showed great initiative and presence of mind and ability to seize a sudden opportunity. Also, that he considers that the enemy was undoubtedly sunk.

3. The British Admiralty Assessment Board, on 17 May, 1943, seconded the attack made by the HERRING on a German U-boat on 21 March, 1943 as "B - probably sunk". The board was at first uncertain for not giving the higher assessment of "A - known sunk", that fact that that the boat was not sinking was evidence to support the sinking of U-boat in that particular area at that time. Revision of this assessment will be made at a later date, if evidence can be found to support a higher assessment.

4. The matter of awards for the above attack will be taken up in separate correspondence in accordance with reference (b).

With reference to paragraph 11 of U.S. HURRICANE'S Third War Patrol, the fact that 51.5 kt/s cannot be received submerged is noted.

2. It is requested that the non-receipt of "traffic" lists, as described in A.P.O.S. 1/43, (Part I), Art.4 (a), may be further investigated and that any established case of a "traffic" list not being made may be reported.

3. It has been the rule for some time for U.S. messages to be transmitted "first on the combined" U.S. - H.S. routines, in order to keep submarines in the Mediterranean, where danger of detection from the air is generally greater than on the home station, at periscope depth for as short a time as possible.

1. NARRATIVE (All times appearing herein are recorded as Zone B). Underway from BASE II, UNITED KINGDOM at 0900 May 4, in company with SHAD and escort vessel H.M.S. LA CAPRICIUSE, proceeding through Clyde area via MUNCHES and west of ORKNEYS and SHETLAND to point of departure.

May 5 - Uneventful, continuing passage in company.

May 6 - 0001 took departure, proceeding independently from position bearing 270° T. from MUGICLE FLUGGA, distant 5 miles. Set course for 62° 0' N., 01° 50' W., as directed by CAPT (S) 9 despatched 051901. 0520 dived for unidentified plane. 0550 surfaced. 0630 sighted plane resembling Liberator; unobserved, remained on surface. 2130 entered area of submerged running and dived.

May 7 - 0730 surfaced in low visibility, resuming passage. 1345 dived continuing submerged running. 2100 surfaced at northern boundary of submerged area. Ahead 11 knots, sea rough, intermittent snows, with ice forming on rigging.

May 8 - 0330 passed through prescribed point 66° 20' N., 110° 15' W., and set course for 67° 40' N., 160° 01' W. Antennae heavily ice-laden; forward and after center-line handrails carried away by ice. 1020 dived to clear ice from topside. 1050 surfaced; forward half of starboard antenna carried away. Ahead 11 knots in snow and low visibility. 2100 set course 270° T. for patrol line Y.

May 9 - During midwatch, outrigger and lead-in on after starboard antenna carried away. 0530 arrived patrol line, commenced North and South running. 0945 submerged to 100' in low visibility and rough seas. 1845 surfaced, ahead steerageway. Splinter shield on 20 mm. mount twisted by seas. Dismounted.

May 10 - Submerged at 1030. 1900 surfaced in moderated seas but not sufficient to clear debris from topside. No 1 auxiliary tank (fresh water) full, with blow and vent, and flood and drain lines frozen.

May 11 - Patrolling on station. 1320 pulled flare and dived for unidentified plane coming in low and fast. 1350 surfaced, set course to make landfall on OLBELINESEY ROCK. 1730 sighted KOLBENISEY bearing 126° T., distant 8 miles. No trace of H.M.S. MIDDLETON.

May 12 - 0103 dived for unidentified plane. 0230 surfaced. No. 1 auxiliary tank freezing and thawing intermittently with sea water in vicinity of 32° F.

1. Patrolling east and west, 15 miles North of KOLBEIN-SEY. 1320 dived in moderated seas to routine torpedoes. 1545 surfaced; cleaned up topside.
: 2. Continued patrol. Lived for two hours during afternoon to routine torpedoes. 1608 sighted Iceland mainland, distant 60 miles, in remarkable visibility. 1700 set course for northern limit of patrol line.
: 3. 0230 reversed course at northern limit. 1400 decoded FOS despatched 151232 changing patrol area and object of patrol. 1720 dived for plane, but apparently was unsighted. 1834 surfaced.
: 4. 0001 took departure from point 1.4 miles North of KOLBEIN-SEY for new station, course 2480 T., speed 10, zig-zag. 0730 sighted North Cape or Icelandic Horn; commenced coasting. sighted about a dozen fishing boats of small size, several of which scurried off at our approach. 0900 passed point A on schedule. 1130 sighted merchantman, tramp freighters of about 2000 tons headed up the coast in position 66° - 13' N., 230° - 35' W., about 5 miles from shore. Vessel reversed course at sighting HERRING, then headed for shore, then resumed original course after determining our non-hostile attitude. Freighter passed about 4000 yards abeam to port and was flying U.S. or British colors. 2230 passed point B 1 1/2 hours late, seas having made up during afternoon such that turns for 11 knots gave a speed of 5 knots.
: 5. Uneventful - rough and wet. sighted unidentified plane at 1535 but remained on surface.
: 6. Passed through point C 4 1/2 hours late. Seas moderated during evening.
: 7. 0032 sighted plane and pulled flare which exploded, damaging flare bracket inside protective cylinder and gouging out wooden deck about 15 feet below. This protective cylinder undoubtedly saved the 0.0.D. from what might have been a fatal accident. Remained on surface. 0230 passed point D 2 1/2 hours behind schedule and commenced diving by day. 0830 dived. Loop reception submerged getting very poor.
: 8. 0115 surfaced, continuing passage. 0307 decoded cancellation of patrol position F.and directing patrol in position G. Set course to conform. 0830 dived. North easterly gale making up during afternoon. Discontinued periscope patrol and took deep submargence.
: 9. 0115 surfaced in strong gale and high seas. Endeavoured to set course for assigned station but swamping seas necessitated making steerageway into sea during remainder of night. 0230 received cancellation of patrol position G. and directing route to patrol in area Al. 0830 dived to deep submergence; set course 1500 T., for patrol area, distant 173 miles. Seas moderated during day.

— page 75 —
0110 surfaced in fog and low visibility. Set speed 10 knots for assigned station. 0225 decoded FOS 211426 directing report of position, course and character of W/T reception. Transmitted HERKING 220315 in reply thereto. 0815 submerged, visibility alternately poor with fog. 2position not fixed for several days.

May 23 - 0115 surfaced. 0540 decoded FOS 221919 cancelling patrol station to which enroute and designating center of area A2 as new station. Set course 0790 T., at 15 knots. Distance 55 miles. 0810 submerged. 1700 surfaced for schedule and sun line - first possible observation since forenoon of May 18th. 1720 re-submerged. Latitude error negligible; no check on longitude. 2000 arrived on station.

May 24 - 0115 surfaced; patrolling within radius of 20 miles of center of A2. 0817 submerged, sea calm; making periscope observations every 15 minutes with 10 feet of periscope. Submerged reception good.

May 25 - 0115 surfaced. 0815 submerged. 1635 surfaced for L.A.N. sun and re-submerged. 2140 surfaced for longitude line and re-submerged. Running fix at 2140 the first fix obtainable in 7 1/2 days. Longitude 17 miles in error but within limits of station.

May 26 - Uneventful - calm with good submerged reception and effective periscope patrol.

May 27 - Continuing submerged patrol. 1345 decoded FOS 271117 designating new station in order to clear convoy. Set course 2700 T., to new station, distant 95 miles.

May 28 - 0110 surfaced; ahead 12 knots to new station, distant 70 miles. 0410 obtained first star fix. 0815 submerged on station, calm and overcast.

May 29 - Conducting submerged patrol. 1700 surfaced for sun line and sea and re-submerged. 1730 decoded FOS 291139 directing patrol in NorthWest corner of A3. Set course 0730 T., distant 124 miles.

May 30 - 0105 surfaced, ahead 14 knots - 95 miles to new station. 0335 in position 540 - 13' N., 410 - 01' W., made doubtful contact on radar, range 2700 yards. bearing 0560 T. Slowed to 1/3 on battery, needed for contact and went to battle stations. Made ready bow tubes. Contact intermittent and radar screen saturated with wave contacts. Closed for 1/2 hour without sighting anything. 0405 disconnected search; the contact undoubtedly had been the result of wave reflections. Resumed course 0730 T., at 14 knots. 0815 submerged. 0845 on station within 20 miles of NorthWest corner of A3. Surfaced during afternoon and evening long enough to obtain sun lines. Seas veering to North West and increasing. Periscope observations difficult and not very effective.

— page 76 —
31 May 1944 - Uneventful - conducting submerged patrol. Seas moderated during evening.

June 1 - Uneventful - periscope patrol effective in calm seas. 1115 decoded FOS 011019 directing departure from patrol and prescribing partial return route. This was a noisy day submerged. Commencing at about 1730 and at odd intervals during the next 5 or 6 hours, heavy distant detonations were heard in groups of 3, 5 and sometimes 8 or more. These had been heard on previous days but not nearly in such number. Some sent vibrations throughout the hull. They were sufficiently loud to awaken persons sleeping and were not unlike those heard on previous patrols in the Bay of Biscay. Although it has been impossible thus far to correlate these with K.A.F. bombings, it is believed that underwater explosions and possibly explosions on Jani near coastal waters may be heard over great distances submerged. In the event that these were bombings asiore on the continent, a transmission interval of some 30 minutes would have to be taken into consideration.

June 2 - Reperated station, diving by day, at 0500. Set course 093° for point G.

June 3 - Uneventful. Passed through point G. at 0615, set course 086° for point H.

June 4, 5, 6 - Uneventful. Passed through point H at 2100. June 5th and commenced surface running. Passed through point M at 1800. June 6th.

June 7, 8 - Submerged on reverse course at 1300. June 7th for 3 hours to lose distance. Passed through point N at 1640. June 7th. Sighted abandoned life-raft in Lat. 56°-26'N., Long. 10°-44'W., at 1450. June 8th. Passed through point O at 1550. June 8th. Fired five rounds from deck gun for test purposes.

June 9 - Arrived rendezvous at 0200. 0350 Sighted BARB and BLACKFISH escorted by CUTTYSAKR. 0415 Commenced passage in company with CUTTYSAKR to BASE II. 1610 Moored BASE II. United Kingdom.

2. WEATHER - Average sea and air temperatures north of Iceland, as reported in the Coast Pilot, appear to be somewhat optimistic. Sea water temperatures were recorded as low as 27°F (at 100°F) and never higher than 34°F on the surface. Surface air reached a minimum of 19°F, and a maximum of 35°F. The percentage of overcast weather was not noticeably less on patrol line Y than the encountered in the anti-U-boat area. The phenomenon of extraordinary visibility was neither remarkable to witness. Sea conditions north of Iceland covered the extremes, averaging about moderate. They were not comparable to those experienced in the Bay of Biscay during the winter months. In the anti-U-boat area typically north atlantic sea conditions were encountered. About half the time effective periscope observations against a target as small as a U-boat were limited to about 4000 yards. Navigation which is restricted to night observations suffers seriously. It is significant to note that during a period of approximately 17 days in this general area only one star fix was obtainable. Re-sort was had, accordingly, to use of sun lines at infrequent opportunities.

3. TIDAL INFORMATION - None of reliable value owing to navigational uncertainties.

4. NAVIGATIONAL AIS - It may be reliably accepted that XOLEBINESKY ROCK is 5 miles to the westward of where it appears on present Admiralty charts. The position shown on U.S. charts is correct.

5. ENEMY WARSHIPS, MERCHANT VESSELS and PATROL VESSELS SIGHTED - None.

7. PARTICULARS OF ATTACKS - None.
8. ENEMY A/S MEASURES - None observed.
9. ENEMY MINE SWEEPING OPERATIONS - None.

10. MAJOR DEFECTS EXPERIENCED - None. The present design of our wing antennae, however, is not sufficiently rugged for use under ice conditions. Suggested improvements are: (1) reduction in the length of the after portions, (2) outriggers so positioned and of such length that their extremities may be worked on from the cigarette deck, instead of requiring a ladder from the main deck. (3) fore and aft, horizontal, diagonal braces on outriggers. (4) more rugged fittings (turnbuckles, eyes, etc.). The parting of these latter was the direct cause of the antennae difficulties experienced on this as well as other patrols.

The matter of No. 1 auxiliary tank freezing, while serious, would not be encountered normally except in very remote localities. Complicated corrective measures would hardly be warranted. The Bureau of Ships has commented in times past, moreover, that this tank is designed primarily for use with sea water, and its use as a reserve fresh water tank is merely an accomodation.

— page 79 —
11. RADIO RECEPTION - Radio reception was generally excellent on the surface and very good submerged while north of Iceland. In the mid-atlantic area, receipt of traffic submerged was unreliable since keel depths of 55' to 58' were usually necessary. These depths were not always practicable. Weak and fading signals were rarely always experienced on the 2145 and 2300 routines.

A large amount of apparently unofficial traffic was heard on 4740 kcs. between May 28th and June 1st. Calls used were not familiar and the procedure was typically commercial. Station call signs WEEM and WEEK were heard most frequently. Although it is not desired to make any accusation, there was reasonably good indication that convoy HX240, then passing, might have been the source of this.

Station serial number of last signal received HS577

12. SOUND CONDITIONS AND LENGTH LAYERS - Sound conditions were generally very good. No density layers were observed.

13. HEALTH AND HABITABILITY - Generally excellent. Four cases of venereal disease made their appearance after departure and received prompt and effective treatment. No sick days were lost.

— page 80 —
18. REMARKS - It is recommended that submarines conducting anti-U-boat patrols be covered by total bombing restrictions and that surface patrolling be discretionary with the commanding officer. This presupposes a submerged patrol when sea conditions permit effective periscope observations, and e surface patrol at other times. The probability of making contact would be increased measureably and prompt receipt of radio schedules would be assured.

Subject: U.S.S. HERRING - Report of FOURTH War Patrol.

Enclosure: (A) Track Chart (To Admiral (Submarines) only).

1. The report of the FOURTH War Patrol of the U.S.S. HERRING is forwarded herewith. The duration of the patrol was thirty-four (34) days. The patrol was conducted off the coast of northern Iceland and in the north mid-Atlantic Ocean as an anti-submarine patrol.

2. The material condition of the subma rine and the physical condition of the crew was of the same excellence that has obtained on all previous patrols.

3. Air temperatures of Iceland from 18° to 35° F. obtained, but no difficulty was experienced in operation of equipment or machinery with the exception of the freezing up of No. 1 auxiliary tank piping system and carrying away of the after centerline handrails and antennae. Corrective action is being taken to increase the ruggedness of the handrail and antenna rigging.

4. The explosion of one of a new lot of emergency recognition flares, which was apparently in first-class condition and had not been wet when ignited, indicates that this type of flare is still unstable in character and dangerous to use regardless of lot. The protective sheathing installed at New London proved effective.

5. The recommendation that "surface patrolling" during daylight be discretionary with the commanding officer is concurred in, when sea, weather or visibility conditions are of such nature as to make submerged patrol ineffective. Efficient use of the radar installations, sound equipment, and lookouts is most important during such periods. Total bombing restrictions would not necessarily add to the assurance of the commanding officer that he would not be bombed by friendly aircraft because of the inherent inaccuracy of aircraft navigation at sea, and would reduce the effectiveness of the A/S measures of aircraft. Hence, the recommendation of the commanding officer in regard to having total bombing restrictions in the assigned patrol area is not concurred in.

6. Because of the restriction placed on the distribution of U.S. submarine patrol reports by the Commander-in-Chief, U. S. Fleet, it is requested that subordinate commands be furnished with only such extracted information as is considered necessary.

2359 (I) completed passage through strait. Observed several floodlights on NW side of KUCHINO SHIMA indicating possibility of construction work.
1 December - 0045 (I) entered assigned area in S.E. corner. Set course for focal point in vicinity of 31° N., 128° E. 0924 (I) radar plane contact (aircraft contact #9) at 19 miles. Submerged. Conducted submerged patrol, made minor repairs to SD radar and took bathymorophograph readings to.300'. 1157 (I) surfaced, patrolling in some general area.
2 December - 0907 (I) plane contact (Aircraft contact # 10) at 15 miles. Submerged. 1212 (I) surfaced, set course 182° T., at 15 knots to patrol approach to AMAMI O SHIMA from S.W.
3 December - 0621 (I) submerged in vicinity of 28° N., 128° - 45' W. 1110 (I) visibility reduced by light rain to 4000 yards. 1115 sound contact (screws) on JP - 1, bearing 155° T. Set course to close and went to battle stations, visibility unencumbered. 1145 (I) heard intermittent pinging dead ahead. 1148 (I) sighted freighter, barely discernible in mist, bearing 135° T. Range about 4500 yards, angle 450 port (contact #1). Maneuvered for 900 port track angle. At next observation, range 4500 yards, target had zigged radically to right presenting an angle on the bow of about 150° port and was fading out of sight. 1204 (I) shifted to reported sound bearings on starboard bow and observed five additional freighters at extreme range of visibility, angles on bow varying from 180° to 90° port and generally indeterminate. 1212 (I) targets were obscured in haze. Probability of hitting was remote, so fire was withheld. Indications were that, in addition to the handicap of low visibility, we had encountered this convoy at a knuckle in the base course. Stood off on North Yesterly course at 1224 (I) to get clear of islands before surfacing, and to trail in reduced visibility. 1300 (I) visibility unlimited, with seas deteriorating. 1754 (I) surfaced in rough northerly sea, ahead on course north at engine speed 12 knots, giving a speed of 6 knots through the water. 2217 (I) took a heavy sea into induction piping and down conning tower hatch, resulting in a number of electrical grounds in engine room and destruction of ventilation supply blower impeller - No spare aboard. Reduced speed to 10 knots. 2300 (I) made radar contact bearing 014° T., range 20,000 yards on same convoy (Contact # 2), range closing very slowly. Additional speed was required at this point to attain position for a night attack, but sea conditions prohibited any further driving without the probability of serious electrical damage to conning tower equipment.

— page 90 —
4 December - 0557 (I) submerged, after having attained a position about 20° abaft the convoy beam and 7 miles to westward of main body. Scattered units extended from dead ahead to 70° relative, and at ranges of 6 - 8 miles. Remained submerged during remainder of day, sees unabated. Further pursuit was considered to be impracticable in view of convoy's night position in proximity to coast and the difficulties of piloting in thick weather among the outlying islands. This was a particularly disappointing chance, frustrated at first contact by low visibility, and then by violent seas which precluded any possibility of reaching a night attack position. Surfaced at 1830 (I) and set course for area. 2300 (I) wind and sea began to moderate. 0906 (I) sighted two small trawlers to S.E. on northeasterly course. Avoided to westward. 0945 (I) sighted plane and submerged (Aircraft contact # 11). 1344 (I) surfaced, set course to patrol area about 60 miles west of DAJNO GUNTO. Sighted several lighted fishing scampers during the night and maneuvered to avoid. Continued patrolling west of DAJNO GUNTO. 0800 (I) set course to patrol E - W lane between QUELPART ISLAND and IKI SULDO. 0942 (I) sighted QUELPART ISLAND bearing 326° T, distant 63 miles. 1356 (I) plane contact (Aircraft contact # 12) at 18 miles. Submerged. Surfaced at 1750 (I), sea glass calm and bright moonlight. 2400 Commenced E - W patrol between QUELPART ISLAND and IKI SULDO. 0030 (I) weather started deteriorating with strong north-westerly winds. 0301 (I) small, darkened trawler (Contact # 3) on starboard bow. Maneuvered to avoid. 0510 (I) high seas with winds approaching gale force - making bare steerageway. 0650 (I) observed small sampan about 1200 yards on port beam - not previously sighted, despite broad daylight, owing to size and sea conditions. In view of difficultlss in diving and generally heavy weather, decided to conduct submerged patrol. 0723 (I) submerged on course 250° T. 1850 (I) surfaced, seas undiminished. Made steerageway during the night on course 280° T. Sighted lighted small craft on two occasions. 0651 (I) weather unabated, - submerged on course 1000 T. Surfaced at 1852 (I) in slightly moderate sea, patrolling NW - SE line across track from QUELPART ISLAND to IKI SULDO. Maneuvered to avoid a lighted small craft at 2253(I).

9 December - Two nights and two days having proved fruitless in this locality, set course 220° T., at 0653 (I) to re-establish patrol west of DANJO GUNTO. 0845 (I) sighted small vessel to SE on northerly course (Contact # 4). Maneuvered for position ahead. 0900 (I) submerged and commenced approach. 0952 (I) identified target as small trawler. Discontinued attack and resumed course 235° T. 1307 (I) surfaced.

: 10 December - Conducting surface patrol to westward of DANJO GUNTO. 0952 (I) set course to patrol across shipping lanes to SW. Manuvorced to avoid small craft on three occasions during the day.

: 11 December - Conducting surface patrol in vicinity of 31° N., 128° E. 0915 (I) plane contact (Aircraft #13) at 14 miles. Submerged. 1012 (I) surfaced, - resumed patrol. 1105 (I) plane contact (Aircraft contact # 14) at 8 miles, closing fast. Submerged. There has obviously been an intensification of air patrols in this area since the productive visit of SEAHORSE. Submerged patrol closer inshore seems to be indicated. 1746 (I) surf.ced. Set course to close DANJO GUNTO.

: 12 December - 0206 (I) made 3J cont.ct on small darkened patrol boat (Contact #5) at 4000 yards. 0208 (I) sighted patrol boat which challenged with a series of I's on screened light. Stood clear to SW. Made several additional small boat contacts during remainder of night. 0637 (I) submerged, conducting periscope patrol. 1807 (I) surfaced - set course to close QUELPART ISLAND. Small craft as usual during the night.

: 13 December - 0633 (I) submerged. 1234 (I) sighted smoke bearing 162° T. distant about 14 miles. (Contact # 6). Set course to close. 1315 (I) commenced approach on normal approach course. Target identified as 5 ship convoy with 2 DD escort and air screen (Aircraft contact # 15). Base course about 300° T. with radical zig-zag. 1403 (I) discontinued approach at minimum range 15,000 yards, angle on bow 900 starboard. Commenced trailing. Established convoy route as passing to northward of QUELPART ISLAND. 1823 (I) surfaced, commenced pursuit at 17.5 knots; sea glassy calm, bright full moonlight. 2120 (I) TAKO abeam to port, distant 2 miles. Stood out to westward for one hour to cover probable convoy route to SW. With no contact after one hour, set course to SW to cover position circles toward SHANGHAI. 2317 (I) sighted faint smoke at 13 miles bearing 248° T. Set course to close.

— page 92 —
14 December - 2325 (I) radar contact on same convoy, (contact # 7) range 23,000 yards. Commenced and around run and tracking, maintaining minimum range of 8 miles. Convoy course 2480 zig zag, speed 8.2.

: 0348 (I) in position dead ahead of convoy, distant 6 1/2 miles, went to radar depth. 0358 (I) periscope depth, target group plainly visible consisting of 2 columns of 2 ships each on line 90 reltivc. Hidway between 2 column lcaders wcs lcrge unidentified transport of 14,000 ton. One DD escort trailing cestern of right hand column, one DD escort loading left hand column - all ships using constant helm. Manouvored to position between transport and right hand column, when zig campolled a stern tube shot at the large ship. 0416 (I) fired tubes # 7 and # 8 on mean track angle 91° Sterbro'd, range 900 yards. (Attack # 1). Shifted to leading freightier of left-hand column. At elapsed times of 41 and 48 seconds heard two hits on transport. 0418 (I) fired tubes # 9 and # 10 on mean track 780 Starboard, range 2100 yards (Attack # 2). Shifted to leading ship of right hand column (tanker of about 7,000 tons) for bow shot. Tubes # 9 and # 10 both misscd. 0421 (I) took a quick look at transport - all abaft funnel was submerged, bow elevated about 15 degrees and deep in the water. Tanker target was now reversing course toward us. At 0426 (I) with track angle 83° starboard range 1300 yards, fired tubes # 1 and # 2 (Attack # 3) the latter failing to fire, probably due to depth charges which had begun to drop. With the first pattern of 5 depth charges completed, observed one hit on tanker under engine spaces, which toppled over the stack. Next to 150' and commenced evasive measures. 0528 (I) fourth and final depth charging, for a total of 25 charges. In general the depth charging was accurate. Except for the first pass, it is estimated that all were within 200 yards and one or two within 50 yards. Sustained no material damage except to S5 radar which was determined later. Stood off to SE submerged during remainder of day. Made periscope sweep when five miles east of the scene and immedi.ately after cessation of pinging. Nothing in sight. Tanker had either sunk or been taken in tow. If taken in tow en easterly course would have been logical. 1810 (I) surfaced - ahead 12 knots returning to area.

— page 93 —
15 December - Conducting surface patrol in visibility intermittently reduced by light rains. 1114 (I) sighted two medium sized trawlers (Contact # 8). to NE on southcoasterly course. maneuvered for position ahead. 1140 (I) lost sight contact in rain squall when dead ahead of trawlers. Trawlers must have made radical course change since contact was never regained. Resumed surface patrol at 1249 (I). 2035 (I) set course for submerged patrol eastward of GYU TO.

16 December - Conducting submerged patrol eastward of GYU TO. 1425 (I) bowplane tilting motor brake seized releasing. considerable acrid smoke in torpedo room before it could be shifted to hand. Isolated compartment and stood off to eastward in overt surfacing should become necessary. 1823 (I) surfaced, patrolling route to IKI SUDO and reverse during the night.

17 December - Submerged at 0620 (I), patrolling due east of HAKU TO Light. No ship contacts, but numerous fishing boats and junks were a continual nuisance during the day. Surfaced at 1815 (I), patrolling some general vicinity as previous night.

18 December - Conducting submerged patrol about 10 miles north of GYU TO. Surfaced at 1823 (I) - set course for southerm part of area.

19 December - Surface patrol - 2100 (I) sighted KUSA KAKI SHIMA. Light bearing 020° T. distant 29 miles. 2200 (I) sighted GATA SHIMA. Light bearing 160° T. distant 31 miles.

20 December - Surface patrol along E - W line in southern part of area. 0930 (I) sighted flying boat (aircraft contact # 16) and dived. 1332(I) surfaced. 1435 (I) plane contact (Aircraft contact # 17). Dived. Decided to remain submerged during reafliner of daylight on the chance that air activity was a forerunner of surface traffic through this vicinity. 1805 (I) surfaced.

21 December - Surface patrolling SW of DANTO GUNTO. Maneuvered to avoid small craft on several occasions. 2230 (I) re-installed main vent operating gear on #4 F.B.T., made dive for trim and removal of residual oil. 2245 (I) set course for northern part of area. The frequency of air patrols, and their failure to attack on several occasions when we were obviously sighted, leads to the belief that their mission is spotting for the purpose of re-routing shipping. Decided to resume submerged patrol in northern part of area.

— page 94 —
22 December - Conducting submerged patrol to SE of GYU TO Light. 1826 (I) surfaced. 2135 (I) SJ radar back in commission after almost continuous repairs since the depth-charging on 14 December. Closed QUELP.RT ISLAND for tuning purposes and then stood to eastward to take station for following day's patrol.

: 23 December - Submerged patrol across track between SAISHU KAIKYO and northern islands of GOTO RETTO. 1819 (I) surfaced, patrolling IKI SULO route, seas deteriorating.

: 24 December - Submerged patrol on north central part of area. Peri-scope observations of limited effectiveness in heavy swells with depth control difficult. 1826 (I) surfaced, set course for patrol station N.W. of OSE SAKI Light.

: 25 - 26 December - Submerged patrolling N.W. and due W. of OSE SAKI Light, seas moderating on 26 December.

: 27 December - Surface patrolling S.W. of DANTO GUNTO. 1808 (I) set course for southeastern part of area. 2228 (I) sighted light bearing 1980 T. resembling that of fishing craft. 2240 (I) made radar contact on same light, range 20,500 yards (Contact # 9). Commenced tracking. Vessel well lighted on straight course 025° T., speed 12.5 knots. 2255 (I) commenced surface approach. 2324 (I) in firing position for 90° port track angle, range 2200 yards established definite identity as a hospital ship resembling MUZUHO MARU (Page 60 - O.N.I, 208 J). Vessel carried conventional HAGUE markings and was well illuminated with a red Cross over bridge and on deck house aft. Broke off attack undetected and resumed southeasterly course.

: 28 December - Surface patrolling E - W in southern part of area. 0915 (I) Aircraft contact (Aircraft contact # 18) - submerged. 1607 (I) surfaced. 2240 (I) fixed position by radar on GAD.A SHIMA and set course to patrol north of TOKARA GUNTO.

: 29 December - Submerged patrol due north of TOKARA GUNTO. 1818 (I) surfaced patrolling same general vicinity prior to departure from area.

: 30 December - 0420 (I) set course for COLINET STRAIT. Observed several lighted small craft. These were invariably grouped on shoal spots and were obviously fishermen. 0630 (I) submerged. 1003 (I) departed area in SE corner. 1754 (I) surfaced ahead on return route.

: 31 December - 1306 (I) sighted probable patrol craft to NW., distant 6 miles. 1458 (I) sighted convoy consisting of 3 ships and 2 escorts bearing 082° T., distant 10 miles, angle on bow 700 port (Contact # 10). Maneuvered for position ahead and commenced tracking.

— page 95 —
1604 (I) in position ahead identified target group as 1. large passenger-freighter of 9,000 ton and two medium sized freighters of about 6,000 tons on line of bearing about 050 - 230 T., base course about 330 speed 8.5 zigzagging 90 degrees using constant helm or very short legs. Passenger-freighter was in center, flanked by other two freighters with one small DD on port flank and another DD or TB on starboard flank. 1618 (I) submerged and commenced approach, radical zigzag giving some difficulty. 1714 (I) attained most favorable position with fairly large port track angle range 4000 yards. Base course apparently had been altered to a more northerly direction. Witnield fire for night attack. 1757 (I) surfaced and commenced pursuit. 1802 (I) made radar contact (Contact # 11) and commenced run around port flank at 17 knots, convoy base course 0000, same disposition. Decided to try to knockout DD escort on port flank in first attack. 2030 (I) observed monost. 2157 (I) maneuver ed from position ahead to attack position. 2214 (I) fired tubes # 1, 2, 3 and 4 (Attack # 4) on mean track angle 106 port, range 3300 yards. Withdrew at full power to the SW. At running tilts of 2 minutes 18 seconds and 2 minutes 33 seconds heard two hits on target. Radar on escort indicated stationary and no pursuit. 2220 (I) felt several depth charges through hull. 2221 (I) observed red flare at scene; shortly thereafter one vessel lighted up, another showed single large flood light. 2245 (I) two more single depth charges. 2253(I) seven miles from scene submerged for reload and check on trim. At this time one floodlight was visible, apparently recovering survivors. 2330 (I) surfaced, ahead 17 knots in pursuit, increasing to 18 knots at 2340 (I). Broadcast contact on area frequency. New Year made radar contact (Contact # 12) bearing 0250 T., range 16,000 yards on convoy. 0013 (I) made small radar contact on stationary object, range 3150. Executive Officer observed the bow of a small ship floating vertically. Commenced flanking convoy to port. 0220 (I) in position ahead, moved out to attack station. Convoy now established as consisting of the three large ships with the smaller escort, vessels in column, escort trailing, heavy ship in the van. Due to small size and bows-on angle, radar experienced difficulty in locating escort and would frequently lose him.

1 January, 1944 - 0000 (I) of the New Year made radar contact (Contact # 12) bearing 0250 T., range 16,000 yards on convoy. 0013 (I) made small radar contact on stationary object, range 3150. Executive Officer observed the bow of a small ship floating vertically. Commenced flanking convoy to port. 0220 (I) in position ahead, moved out to attack station. Convoy now established as consisting of the three large ships with the smaller escort, vessels in column, escort trailing, heavy ship in the van. Due to small size and bows-on angle, radar experienced difficulty in locating escort and would frequently lose him.

— page 96 —
0246 (I) commenced attack from port side. 0303 (I) commenced firing bow tubes, 3 at leading passenger freighter (Attack # 5) and 3 at second ship in column (Attack # 6). Inability to locate escort at this time caused some concern. \'ithdraw at full power to SW. At approximate running time of 2 minutes - 15 seconds observed two flash hits on leading ship, not more than five seconds apart and closely-spaced, followed by the flash of one hit on the second ship about ten seconds later. Picked up escort on the port quarter of convoy while retiring, range 3000 yards, but he was heading toward disabled ships. 0308 (I) felt 3 depth charges. 0309 (I) either escort or remaining freighter obligingly, illuminated scene with an arc search light. Passenger freighter was settled to deck line going down; second ship was down heavily at one end with general abandonment in progress at the other. Lost contact on escort at 5000 yards. At 11,000 yards lost the heavy ship contact, two contacts remaining. At range of 14,000 yards radar screen cleared of all but one contact. 0327 (I) approximately seven miles from scene, submerged for re-load. Heard intertitle about 6 single depth charges. 0417 (I) surfaced, clearing locality to SE. Remaining hour and one half of darkness was insufficient for any further attack. 0612 (I) submerged to pass New Year's Day unmolested, and for rest and recuperation. During afternoon heard distant, single depth-charging on four occasions. 1755 (I) surfaced, aned to regain return track.

2 January - 0204 (I) set course 0860 T. on prescribed route.
3 - 4 January - Uneventful.
5 January - 1608 (I) set course 1110 T. to intercept SCORPION for transfer of injured man.
6 January - 0756 (I) made rendezvous with SCORPION on schedule, sea conditions rough. 0945 (I) discontinued transfer attempts by mutual agreement as involving too much risk to injured man. SCORPION reported fracture mending with no apparent complications. Deported 30-07 N. 167-30 E. using return route from AREA TMBLIVE, SCORPION standing off to westward. Inflated rubber boat left adrift in that position.

7 - 8 January - Uneventful.
8 January - Made scheduled rendezvous with MIDWAY air escort at 0800 (Y). 1100 (Y) moored MIDWAY lagoon.

1. WEATHER
- No heavy weather was experienced enroute to the area. There were several rough days returning. While in the area, five or six days of strong North westerly winds occurred. These were accompanied with rough sea conditions making depth control at periscope depth difficult if not impossible. Sharp temperature drops followed in the next wave. The storm on the night of 3 - 4 December, when in contact with a convoy and west of TAKARA SHIMA, was the worst encountered and made possible their escape. The majority of the days in the area were excellent for periscope work with only two days of flat calm.

(D) TIDAL INFORMATION - Currents in general agreed in direction and velocity with Pilots and with digests of previous patrols. The NE set in the northern part of the area will shift to east after several days of strong NW winds. A strong (1.4 knot) set toward 235° T. was felt on the track between longitudes 142 E. and 145 E. both cutbound and inbound. Soundings on chart 5494 are unreliable except at the 100 fathom curve. It is recommended that they not be used for estimating the ships position.

(E) NAVIGATIONAL AIDS - The following lights were observed to be burning with light list characteristics:

GAJA SHIMA
GYU TO
CHACHI TO
KUSAKAKI SHIMA

1. MINES - None observed
(J) 2. ANTI SUBMARINE MEASURES AND EVASIVE TACTICS.

AIR PATROLS - 1. Air patrols were encountered north of the BONINS when outward bound. None were seen on the return trip. After sighting a submarine, "baiting" tactics are apparently employed, the plane remaining in the same general area awaiting another opportunity to attack. These patrols are persistent and will hang on until total darkness. There was one indication wherein aircraft radar may have been employed, just prior to darkness.

2. Based on previous reports, air patrols in area NINE have been intensified to a great extent. Contacts were made almost daily when on the surface and, to some degree, they restricted area coverage.

3. There is evidence that air patrols, in lieu of attacking, are used for spotting the submarine position and re-routing traffic accordingly.

4. There were no aircraft contacts on bright moonlight nights. The air screen on the convoy of 13 December was withdrawn after dark.

PATROL VESSELS - 1. Small craft, both lighted and darkened are numerous in the area and contribute a high nuisance value. They were concentrated particularly west of DANJO GUNTO, east and northeast of QUELIPAT ISLAND and east and southeast of KYOBUY TO.

2. Small trawlers of about 50 ton operating in pairs are well scattered throughout the area.

COUNTERATTACKS - 1. During the depth charging on 14 December one escort maintained listening contact while the second employed pinging and conducted the attacks. Of the four runs made, one consisted of an almost simultaneous pattern of nine charges, the others were consecutive drops, apparently made on straight runs, the interval between charges being about 5 seconds. There was one very close straddle on the port quarter and starboard bow.

EVASIVE MEASURES - 1. Silent running at creeping speed was used at depth 150'. Course was changed whenever screw contacts appeared to be on a steady bearing. Temperature gradient was slightly positive - no density layer existing.

— page 108 —
1. Both continuous helm and short leg zig zags are being employed.
2. Zig zag was continued after moonest and when total darkness had set in.
3. After the first attack on the night of 31 December, convoy changed position from line to column, the one remaining escort trailing on port quarter.
4. While tracking for the second attack, convoy speed changes were definitely confirmed - speeds checked consistently at eleven knots over a period of time and then would drop at irregular intervals to seven knots.
5. In addition to speed changes, constant helm was superimposed on a conventional zig-zag with legs of about 10 - 12 minutes duration. Employment of these convoy tactics on a dark night appears to indicate some degree of desperation.

(K) MAJOR DEFECTS AND DAMAGE - Performance of material equipment was generally very good. The seizure of bow plane tilting motor brake is attributed to faulty adjustment. There was no recurrence after adjustment. Hydraulic leakage past copper packing ring on both sound heads will necessitate their removal for re-wiring. Flooding or moisture in binoculars continues as an unsolved problem. The seriousness of this should merit more adequate corrective measures than those now existing. A weather proof binocular designed for the pressure-moisture peculiarities of submarines is considered to be an urgent military necessity.

(L) RADIO - Reception of the HAIKU broadcasts was satisfactory. During darkness 4525 and 9090 kcs were generally good. During daylight 9090 and 14390 kcs were readable but at dawn and dusk all frequencies were unreadable. 16.68 kcs was found to be unreliable. Interference from SD radar was noted. 17370 kcs was not heard. The two blind transmissions went through successfully.

(M) RADAR - The SJ radar was inoperative for a period of 9 days while in the area as a result of depth charging, and during the latter half of the return journey. Technical aspects of the difficulty will be covered in the regular radar report.
   - SD radar performance was excellent. A sustained arcing across the mast head would occur however, if the antenna was not permitted to drain several minutes before cutting in. This is considered abnormal. Investigation for possible leakage will be conducted during re-fit period.

Via: (1) The Commander Submarine Force, Pacific Fleet.
(2) The Commander-in-Chief, United States Pacific Fleet.

Subject: U.S.S. HERRING -- Report of War Patrol Number SIX.

1. HERRING was patrolled by the patrol boat USS HERRING. The patrol boat was first to be conducted in the Pacific Area. Patrol extended over a period of fifty-four days, twenty-nine of which were spent in assigned area, and was terminated by provisions of operation order.

2. HERRING made six aggressive attacks on two convoys.
   (a) Contact was made on a 5 ship convoy with air and destroyer escort at 1234, 13 December. After trying to close submerged HERRING trailed until dusk, surfaced and commenced a well conducted search. At 2325 contact was regained and at 0416 attack commenced at radar depth. Two stern shots were heard to hit the largest ship, a transport, and two other stern torpedoes missed a freighter. Two bow shots were fired at tanker but one failed to fire as 5 depth charges went off. One hit in engine space of tanker toppled the stack. Depth charging prevented further observation. When last seen transport was submerged to funnel with bow 150 in the air and undoubtedly sank. Tanker was either sunk or taken in tow. However, nearest land was 60 miles to eastward and 120 miles to westward. HERRING covered eastward line of retreat and could not locate tanker.

   (b) A convoy of 3 freighter escorted by 1 destroyer and another destroyer or torpedo boat was sighted at 1450, 31 December. After a 2 hour approach favorable firing position not being attained HERRING held off for night attack. A night surface and around run resulted in surface attack with 4 bow tubes. Two timed hits were made in small destroyer resembling CHIDORI class. Retirement was made on

CONSUESPAG WAR PATROL REPORT NO. 248.
U.S.S. HERRING - SIXTH WAR PATROL.
From: The Commander Submarine Force, Pacific Fleet.
To: The Commander-in-Chief, United States Fleet.
Via: The Commander-in-Chief, U. S. Pacific Fleet.
Subject: U.S.S. HERRING (SS233) - Report of Sixth War Patrol.
(15 November, 1943, to 8 January, 1944).
1. The sixth war patrol of the HERRING was its first conducted in
areas of the Pacific Ocean. The patrol was carried out in the Northeastern part
of the East China Sea.
2. Excellent area study and coverage was made and it is of note that
most of the traffic in this area is now at the upper part.
3. All the attacks made were aggressively conducted and severe damage
was inflicted upon the enemy. The attacks made on the convoy on New Years Eve were
tenacious and exceptionally well conducted.
4. The "baiting" tactics of the enemy aircraft patrolling north of the
PONINS is of note. It is also noted that aircraft anti-submarine activity has be-
come intensified in the East China Sea area. The practice in this area appeared to
be that of spotting and rerouting traffic around the HERRING's locality.
5. This patrol is considered successful for Combat Insignia Award.
6. The Commander Submarine Force, Pacific Fleet, congratulates the
Commanding Officer, officers, and crew for this aggressive and successful war
patrol. The HERRING is credited with having inflicted the following damage upon
the enemy:
SINK
1 - Transport (unidentified class) - 14,000 tons Dec.
1 - Transport (KATORT MARU class) - 9,500 tons Jan.

2015 (I) Radar contact (contact.j#7) bearing 325° relictive, range 4100 yards. Visibility poor. 0.0.D. machovered to put "pips" astern.
2018 (I) Range was closing rapidly, now 2200 yards, so ordered increase of speed. During turn two wakos were observed. Thought that they were two small patrol boats heading for us with all the speed they had.
2020 (I) No increase in our speed yet; probably some misunderstanding in maneuvering room. Ordered "All cleared emergency" as range was now 1600 yards with wakos a little on our starboard quarter.
2022 (I) Changed course to left to put wakos astern again.
2023 (I) Radar range now 1450 yards, and target was described by the 0.0.D. and lookouts as a large submarine with heavy bow and stern wakos.
2227 (I) Our speed increasing but range remained steady.
2228 (I) Range commenced opening rapidly as target probably saw us and turned away.
2230 (I) Lost radar contact at 5000 yards. Submarine might have submerged. Stood out at 17 knots clearing area.
2145 (I) Changed course to return to best estimated position of target but contact never regained. Made very grave error in thinking too much about increasing our speed as range was decreasing instead of getting ready the after tubes. (a golden opportunity was certainly missed on a very valuable target.)

15 March.

2235 (I) Radar depth and contact at 550 yards. Went to 80 feet again. Charged course to ride with the Japan stream and open out from this area. With this intense air patrol shipping must be accurate through this area.
2350 (I) Surfaced; sea smooth partly overcast, visibility good when moon was clear.

17 March.
Patrolling off ASHIZURI SAKI on southerly course at 8 knots.
0009 (I) Radar contact bearing 150° relative range 23,000 yards. Charged course and speed to close and to track. There were five "pips" and appeared to be lying to. 30 miles bearing 100° true from ASHIZURI SAKI. Closed to 12,000 yards slowly. We were in the unfavorable position with the moon east, the convoy had the dark island background.
0045 (I) D/F bearings on 500 KCS in direction of true bearing of target. The signals would be heard only when the SJ radar was trained on the bearing and ceased as soon as we trained off bearing. The target might have had radar detectors and again it might have been coincidental.
0100 (I) Radar contact on another group of five ships, range 18,500 yards bearing 030° relative. Commenced tracking the new target, course determined to be 240° (T) possibly going to join first group of ships.

0104 (I) Sighted plane (aircraft contact #12) running lights close aboard dived to 120 feet.
: 0155 (I) All clear; surfaced. Radar contact on both groups of ships apparently still trying to join up. Three wcs still the signals on 500' KCS between the two groups.
: 0210 (I) Came to the conclusion that this convoy was joining up and would most likely proceed on a southerly or south-easterly course at about 8 knots. As the visibility was now good, the moon against us and with the air activity over the area decided to proceed to an estimated 0700 enemy position. Also broadcast on 450 KCS the convoy information.

: 1935 (I) Radar contact 20,300 yards bearing 3450 (T) approximately on same bearing as last night's contacts. Tracked and no apparent target movement.
    Radar Officer determined "pips" to be double echo off the high peaks about 70 miles away. Now we wonder if the ten ship convoy 17st night was a double echo. Still where was the traffic on 500 KCS D/F's on the correct bearings and the numerous plane contacts!
: 2150 (I) Changed course to 200° (T) for southeast corner of area. Weather still bad.

2037 (I) Channel course to 000° (T); commenced tracking, Battle stations torpedo. Visibility poor with a heavy sea running.
2055 (I) Deter.lined course to be 015° (T) speed 23 knots. The targets are probably 2 destroyers in line of bearing.
2104 (I) On the normal approach course trying to close the targets, we could only make 12.5 knots at full speed. From the plot it almost looked as though the targets were making an end around on us, as the bearing moved up the starboard side rapidly. In this sea and with his speed, we could only hope for a zig towards us.
2137 (I) They did zig towards us range closing but still out at 6,500 yards and track angle increasing. Made ready the bow tubes for a long range low-power shot with about a 1400-port track angle. Thought we might have a chance as they were tracking nicely. Waited for a zero gyro angle and at

0100 (I) Battle stations and got ready on four generators. Swung for stern shot. Target not visible at range 7,500 yards.
0111 (I) Stopped waiting for target to come on the firing bearing. Target was now a small black blob, no definite silhouette.
0117 (I) Target 2,400 yards target was determined to be PC type patrol boat. Did not consider him worth torpedo, so broke off attack. Opened out from target.
0128 (I) Secured from battle stations.
0135 (I) Shifted to one generator and continued patrol to southward.
0920 (I) Submerged in Latitude 31 - 48 N., Longitude 132 - 56 E. because of unfavorable plane weather and patrolled to eastward.

2246-10 (I) Saw one torpedo hit and target enveloped in smoke almost immediately. About 30 seconds later 2 more explosions were heard and flames were seen. Sound like gun fire, but flames did not appear to be that of gunfire. Target dead in water.

2248 (I) Radio reported considerable traffic on 500 KCS close aboard. Many groups copied as "RSS" were sent.

2251-41 (I) Heard two distant explosions, timed as 'end of run torpedo explosions.

2252 (I) Target was underway now and changed course to right. Was tracked and plotted over our firing position with speed increasing slowly. Finally steadied on course 290° T, speed 11 knots.

2303 (I) Changed course to regain position target now on base course 310° (T) zigging 20° to right and left of base course with legs of about 8 and 15 minutes duration and speed changes between 8 to 14 knots. Target doesn't appear to be hurt much with speed she is making.

2353 (I) From our position and time remaining found that we would not gain favorable position for another attack so abandoned attack. Secured from battle stations. Set course to clear area.

The large target carrier, was in the center with one of the two medium targets, large destroyer or cruiser, was 1300 yards on the port bow the other 1500 yards on the port quarter of carrier with the small target, destroyer, on the starboard quarter.
0103 (I) Targets were tracking on base course 065° (T), speed 19 knots, with a.450 constant helm, zigs about every three minutes. Radar was used very sparingly as it was assumed the targets had their own radar or were equipped with radar detectors.

— page 128 —
0111 (I) Went to radar depth to continue approach at a range 10,000 yards to nearest escort. Made ready 10 tubes.
: 0114 (I) Heard heavy dull explosion gunfire close aboard, radar range to escort 9,500 yards to carrier 10,800 yards. Assumption of their radar equipment correct. We could not see them before diving, and I don't think that they saw us. Sent deep. Targets turned away and went around us. A tough one to lose.

The only answer is that the depth set was too great. 'We were misled by a large "pip" from 18,000 yards into firing point. No target maneuvers until after explosions. 'Target "pip" still on radar screen. These explosion times seem quite a bit short for the usual end of run explosions.

1. MINES - None observed.
2. (J) ANTI-SUBMARINE MEASURES AND EVASION TACTICS.

No strong A/S measures were encountered during this patrol, and patrol activity was suprisingly light, air patrols predominating. Only seven patrol boat sightings were made, and one of these on March 3 sighted us just before diving time off SHIMANOURA SHIMA. He appeared to be locking for us after we dove, but no further measures were taken. We were challenged on the morning of March 16, but submerged with no further contact.

There was no retaliation after the two night attacks made on destroyers. On the morning of March 25, at radar depth during approach on carrier and escorts, we were fired upon at range of 10,800 yards from carrier. Radar was used very sparingly, kept trained well clear of target when not taking observations.

Air patrols were numerous both day and night. There were no indications that we were sighted by these patrols as no usual aircraft attacks were made. Instead of attacking, the planes could have been spotting us in and rerouting the traffic accordingly.

(K) MAJOR DEFECTS AND DAMAGE

The material performance of HERRING was excellent. The following were the only defects noted:

(1) The shutter of # 7 torpedo rattles and with following sea it bangs excessively.

(2) In making ready # 4 tube on 28 March the shutter and outer door had to be opened with more strength than usual. The tube was not fired and on securing, the outer door and shutter could not be fully closed. The trim pump could not handle the quantity of water entering. The shutter roller is either off its track or the outer door gasket is hanging loose. The torpedo will be removed at Midway.

On arrival Midway it was determined by divers, that the after shutter roller stop was missing and that the shutter roller had ridden off it's track. The hinge pin held shutter on. Shutter was removed.

The outer could not be fully closed after removing shutter. Either the door or it's operating rod is sprung. Torpedo not removed.

— page 140 —
3) Both periscopes were foggy and need drying out and re-charging.

(4) There is excessive wear on main bearing on waterbury speed gear of stern plane operating mechanism. There appears to be misalignment between the speed gear and the reduction gear to the stern plane operating mechanism. This was probably caused by excessive load being placed on the stern capstan during heavy weather at Midway.

(L) RADIO

Reception the HAIKU broadcasts was satisfactory. 4525 kcs and 6380 kcs were used during hours of darkness, and 14,390 kcs during daylight. On several occasions there appeared to be definite jamming on 6380 and 4525 kcs.

(RADAR

The SJ radar performance was very good. Ranges on land were excellent. On two occasions 2 echoes were obtained on land more than 75 miles distant. Farthest reliable range on a ship was 28,000 yards.

SD radar performance was satisfactory. Only minor breakdowns occurred in both sets.

(N) SOUND EQUILIBRIUM AND CONDITIONS.

Throughout the entire area the sound conditions were generally poor. Not once did sound pick up any of the various patrol boats encountered. On 2 March off ASHIZURI SAKI the high speed screws of an Otori Class torpedo boat were heard only momentarily.

(O) DENSITY LAYERS.

All bathymetrograph cards with the exception of one for a 300 foot dive off TOSAKI HANNA which indicated a negative gradient of 1° per 100 feet showed isothermal layers. Temperature variations at constant depth were noted on submerged days.

(P) HEALTH, FOOD HABITABILITY.

Health was generally excellent. There were a few minor injuries that were expertly handled by the pharmacist's mate.

Food was plentiful, well prepared and varied as much as can be expected. For the first time sufficient quantities of fresh potatoes and onions were carried to last practically the entire patrol. From comments heard, this was of great pleasure to all hands.

1. PERSONNEL.
The new commanding officer took over a boat with a well trained crew of both officers and men. There was nothing to be desired in the manner in which all hands performed their duty. There were no trying combat conditions during this patrol.

The new men as usual were eager to get started on their qualifications and with quite some pushing old hands completed qualifying.

(a) Number of men on board during patrol. - 71
(b) Number of men qualified at start of patrol. - 41
(c) Number of men qualified at end of patrol. - 55

3. Air patrols were numerous both night and day. Surface ship patrols were surprisingly light.

4. On arrival, the health of the crew was excellent. The material condition of the ship was very good, except the defects and damage as noted in paragraph K. The Bese will refit the HERRING and will accomplish all repairs during the normal refit period.

5. The commanding officer, officers and crew are to be congratulated on their trying patrol and damaging one destroyer.

1. It is with deepest regret that the Commander Submarine Force, Pacific Fleet, announces that the U.S.S. HERRING is overdue from her eighth war patrol and must be presumed lost.

2. In accordance with Commander Task Force Seventeen Operation Order No. 163-44, the HERRING, commanded by Lieutenant Commander D. Zabriskie, Jr., U. S. Navy, departed Pearl Harbor on 16 May 1944, with orders to proceed to the Kurile Islands to patrol to the northward and eastward of a line drawn between Latitude 45° North, Longitude 155° East, and Latitude 51° North, Longitude 146° East, until sunset on 11 June 1944, at which time the HERRING was to patrol the area to the south and west of this line and north of Latitude 43° North. After topping off with fuel at Midway on 21 May 1944, she proceeded via great circle to the northern portion of the Kurile Islands. Later the same day the BARB departed Midway to patrol the southern portion of the Kurile Islands. The BARB's orders directed that after sunset on 11 June 1944, she was to patrol to the north and east of the line previously described. No word has been received direct from the HERRING since her departure from Midway.

3. As recorded in the BARB's report of her eighth war patrol, the BARB and HERRING rendezvoused on 31 May 1944, in approximate position Latitude 45°24' North, Longitude 150°-02' East, where it was decided that HERRING would patrol area to north and east to Matsuwa while BARB would cover area to the south and west. The Commanding Officer of the HERRING informed the BARB at this time that on 29 May 1944, the HERRING had sunk a KAMIKAZE Class destroyer to the eastward of Onekotan To. A few hours after parting company with the HERRING, the BARB made contact with an enemy merchant ship. While developing the contact at 1252 King, distant depth charging was heard which was thought to be an indication of the HERRING making an attack. At 2200 King a prisoner was picked up by the BARB who indicated that the HERRING had sunk the escort vessel of a convoy that the BARB had

**been attacking. Interrogation of this prisoner after his arrival Pearl Harbor revealed that the [SHIGAKI, a new type DE built in 1942, had been sunk by a submarine with one torpedo hit in the stern. This fortunate sinking of an escort vessel resulted in the scattering of the convoy, two ships of which passed near the BARB and were sunk.**

4. On 3 June 1944, orders were sent to the HERRING and BARB directing them to remain outside of a restricted area in the vicinity of Matsuwa in which friendly surface forces would be operating. Both submarines were ordered to acknowledge this ever received from the HERRING.

5. The HERRING was scheduled to depart patrol area on 26 July 1944 and if her schedule had been followed using normal cruising speeds, she should have arrived Midway on 3rd or 4th of July. On 27 June 1944, Midway was directed to keep a bright lookout for HERRING who might be approaching without being able to transmit by radio.

6. It is impossible to determine if the registered publications carried by the HERRING were compromised. She carried publications authorized for use in salvageable waters.

7. This was the eighth war patrol for the HERRING and the second with Lieutenant Commander D. Zabriskie, Jr., as Commanding Officer. The first five patrols for the HERRING were conducted in the European theater. The remaining patrols were conducted in the Pacific theater of operations. Lieutenant Commander Zabriskie had distinguished himself while making seven patrols in the U.S.S. TAUTOG, during which time he was an invaluable asset to the ship and his Commanding Officers. For the fourth war patrol of the TAUTOG he received a letter of commendation from Commander Task Force SEVENTY-ONE. For the seventh war patrol he was presented the Silver Star Medal. It is most regrettable that this outstanding officer and up-and-coming Commanding Officer was unable to make his own report on what appears to have been the start of an outstanding war patrol.

References (b), (c), (d), and (e) report an action involving one of our submarines which took place off the Island of Matsuwa on 1 June 1944. As the only two submarines present in that area were the BARB and the HERRING and as the BARB has reported that she was not the submarine concerned, the action described must have been with the U.S.S.
