EDITORIAL

 

As we begin the 19th annual volume of the Fifties Frog Magazine there is still plenty of material surfacing; some documents historical events, some tainted by fading memories and some just for fun stuff. All is welcome and we will attempt to be clear about its authenticity or lack thereof.  If we fail in that do not hesitate to call the breach to our attention. If we do not tell the story now it may not be told.

 

Lee Hughs has the thankless job of keeping a Roster of our Frog members, spouses and friends. Our primary method of communicating is by email. To go to another method would be costly in money and manpower. So, it is incumbent upon the member to keep Lee informed when the email address changes.

 

Any Frog or Spouse of a Frog who wishes to be in communication with others will soon have an updated list of addresses for their use. 

 

Another issue is notification when a member or spouse deceases. Lee and your editor should both be notified in the event that happens. 

 

Suggestions for improvement of the magazine are welcomed.

Vignettes of WWII UDT in the Pacific

 

[Editor’s note: this article is a continuation of the series provided by Mack Boynton, who preserved an old history of UDTs of which there is one typewritten copy extant. There is more to come. Just a reminder to the reader that the grammar and misspellings are largely left as they appear without question or comment. For those who may not be familiar with it, the term (sic) is an editorial way of saying the preceding spelling, etc. is the error of the author not the editor.

 

This chapter is especially rife with errors of many kinds: spelling, grammar, dropped sentences and sections repeated. Admiral Onderdonk is also listed as Onderdonf and Oderdond. Nevertheless, the chapter has some interesting detail of early UDT learning experiences – perhaps more than any previous chapter.  For example, it was Team SEVEN that developed high-speed pickup.

 

Your editor is a founding member of the Laffite Society, located in Galveston, Texas, so it was of interest that Team SEVEN was once on the USS JEAN LAFITTE, AKA USS WARREN.  Like it’s namesake the ship had a very confusing existence. A brief history of the WARREN is given in the Dictionary of American Naval Fighting Ships and its service record tracks closely that of Team SEVEN. Those interested can view it online with access through Google or other channels.]

HISTORY OF UNDERWATER DEMOLITION TEAM SEVEN

 

Composed entirely of Sea Bees from Camp Peary, Virginia, Classes 5 and 5A went through training at Fort Pierce, Florida during March and April of 1944 in units of one officer and five enlisted men. At this time the program had not developed fully, as there were on (sic)  precedents by which to proceed. As a result there was very little swimming practice; the problem of approaching the beach and returning was never solved, at least to the extent of a maiximum (sic) survival of personnel, and personnel were too heavily clothed in guns, field shoes, helment, (sic) and heavy "Mae West" life jackets. Later experience, of course, brought about radical changes in these three phases of training. Early in April the units were concolidated (sic) to form teams SIX and SEVEN.

 

On Easter Sunday, 9 April, Team Seven departed for San Francisco, and then by ship to the Demolition Base at Maui, T.H. Soon after its arrival there, the team received Lieutenant BURKE as its Commanding Officer and Lieutenant (jg) ONDERDOND (sic) Became Executive Officer.

 

Here also the training program was in its embryonic stage; moreover, as always remained the case, it differed from Fort Pierce doctrines. This team was among the first to recive (sic) emphasized training in reconnaissance. The methods there developed as to dropping swimmers, obtaining information and recording it on charts became fundamentally the basic form of swimming reconnaissance. One major fault corrected, after the teams experience later at Saipan, was in having the LCPR stop beside each swimmer to retrieve him. Moreover, no opportunity was recived (sic) to practice off an APD, a later development of great worth.

 

On 30 May, in company with Teams FIVE and ISX (sic) on their APD's, Team  SEVEN left for the Saipan operation aobard (sic) the U.S.S. BROOKS, an APD. On the way operational plans and charts were studied and the men briefed.

 

At 0830 on 14 June 1944 (D-l Day the reconnaissance units of Team  SEVEN embarked in four CLPRS from their APD. Each full platoon of the team was used as a unit and assigned a partucular (sic) beach to reconnoiter. The team was assigned the beaches Blue One, Blue Two, Yellow One and Yellow Two and of these Platoon One was asigned (sic) Yellow Three, Platoon Two was assigned Blue One, Platoon Three Yellow One and Platoon Four, Blue Two. Each platoon was directed to determine the following about it's assigned beaches.

 

(a)      Determine location and extent of underwater obstacles, antiboat mines, barriers, booms and all other obstructions which would    prevent the passage of LVTs.

 

(b)     Select and mark best approaches to designated beaches through which           channels could be blasted.

 

(c)      Existence, height and charadter (sic) of coral lip at edge of reef.

 

(d)     Depth of water over reef and in lagoon.

 

(e)      Condition of surf at edge of reef.

 

(f)      Extent and types of obstacles encountered on reef and in approaches    to designated beaches.

 

(g)      Extent, type and size of anti-boat mines encountered.

 

(h)     Extent and type of any obstacles observed on beaches proper.

 

(i)      Character of seaward edge of reef.

 

(j)      Estimate of ability to clear desired channels.

 

In regards to demolition, Team SEVEN was ordered by the Operation Plan to do the following:

 

(a)      Clear and mark at least one channel with a minimum width of at           least fifty feet from the edge of the reef to each of the designated           beaches to allow passage of LVTs.

 

(b)     Clear beaches of all horned scullys, jetted rails, booms, barriers, etc

 

(c)      Blast and mark at least two twenty feet wide passages per beach over    lip of coral reef in order to permit passage of DUKWs.

 

To insure that the maximum benefit from reconnaissance be attained it was ordered that the data obtained be disseminated to Admirals HILL, TURNER, and OLDENDORF (sic) stationed on ships U.S.S. CAMBRIA, NOROVIA and INDIANAPOLIS respectively as soon as possible after reconnaissance.

 

While the beaches had been failry (sic) easy to distinguish before disembarking, platoon leaders were given last minute insturctions (sic) to rendezvous about the ship to get proper compass bearings to each beach. This information was not received and the LCPRs proceeded without guidance.

 

Proceeding under sporadic and poorly directed Naval gunfire support, each platoon conducted it's reconnaissance. While casualties had been suffered by some of the personnel in the LCPRs prior to leaving the craft, the reconnaissance was completed and all required information secured.

 

The reaction of the Japanese to our Naval fire is difficult to evaluate. At Saipan they opened up on the supporting warships with some large guns, necessitating a withdrawal to a longer range and return to former positions after knocking out the disclosed targets. Partly as a result of this, heavy enemy machine gun, sniper, small caliber gun and mortar fire was encountered. In addition, twelve barges moored alongside the pier at Blue One Beach endangered the team with heavy and fairly accurate mortar fire. Naval air support was at this time occupied elsewhere and the little air cover provided was very poor and inefficient.

 

In training at Maui the only tactic used in picking up a swimmer was to approach him with the craft, bring it to a stop and allow the Swimmer to drag himself into a rubber boat which was provided alongside the LCPR and from there jump into the LCPR. Here it was discovered that motion of the LCPR was necessary to minimize the chances of receiving hits from the mortar she1ls that the Japs were dropping around the LCPRS (sic) . Consequently a life ring with a line attached was rigged and this was thrown to a swimmer as the LCPR approached and passed him. The end of the line was held by a man in the boat and the swimmer was dragged safely into the LCPR. A smoke screen was ordered by Lieutenant BURKE just prior to this which probably hepled (sic) reduce the accuracy of the enemy fire.

 

During the reconnaissance, Japs could be seen moving around the beach and several gun and sniper positions were apparent. By using, thirty caliber machine guns mounted on the LCPRs and manned by APD gun crews, at ranges from 500 yards to 800 yards, and firing over the heads of the swimmers, the intensity of enemy fire was considerably reduced. As a result of this experience, on subsequent operations each LCPR was equipped with a bow and stern fifty caliber machine gun in addition to the thirtys. Also selected team personnel were later given training in machine gunnery and provided the gunnery for later operations.

 

By drawing fire from the beach installations and barges valuable information as to the enemy fire power was secured. Heavy Navy gunfire was later concentrated on known targets on the beach, barges, and snipers in the tree tops on D-l Day and the morning of D-Day preparatory to the landing of the assault troops.

 

While all the swimmers bad plastic diver's slates and pencils with them to use on the reconnaissance to note information, none were used by the men because of the undesirability of stopping long enough to record what was being seen, thus minimizing the chances of being hit by the enemy.

 

Radio communication between the LCPRs and the swimmers was carried out with no success on this operation but the use of SGR 536’s  (sic) was provided for this purpose. One swimmer for each beach, usually an officer, was provided with such a radio but found it cumbersome and impractical when evasive tactics and speed became necessary to avoid being hit by enemy fire. These SCR 536's (sic) were abandoned by the swimmers carrying them on the beaches at Saipan. Radio communication between the LCPRs and the APD was maintained with SCR 610s. However, communications between the LCPR and the Naval Fire Support Ships was not direct on this operation which made calling of fire support from these ships very ineffective. Plans for subsequent operations by Team SEVEN embodied direct communication between LCPRs and fire support.

 

No obstacles of man-made nature or mines were found on the beaches; consequently, no demolition of man-made obstacles was required. As noted heretofore the Operation Plan called for clearing and marking of certain channels through the reef. However, the discovery of a highly navigable natural channel Charan Kanoa Channel, on Blue Beach One which would serve well to get Landing Craft into the beach proper, minimized the necessity for blasting channels through the reef. As navigational aids to small craft, two buoys were placed at the mouth of Charan Kanoa Channel at 2200 on D-Day. In the morning of D plus 1 Day eight additional buoys were placed to further difine (sic) this channel.

 

Some blasting for LST and small boat channels was attempted but very little success was realized. On D plus 1 Day the Blue Beach Beachmaster requested that a 100 foot channel be blasted through the reef several hundred yards to some deeper water along the beach. The previous day's reconnaissance had showed, however, that the water along the beach at the part selected was not navigable even for small craft and a channel would serve no useful purpose. However, it was decided that an attempt should be made so on D plus 1 night the work was performed. The reasons for failure to realize a true channel are several, of which the following may be noted:

 

(a)      Just prior to firing a message was received to hold the firing period           until the following morning, as at that time, the front line was less           than 200 yards offshore and any blasting would have endangered           our own Marines. Thus after being exposed   to the action of the surf           overnight, it was found on firing the explosive charge the next    morning that some of the Prima cord had become wet. As a result, detonation of the powder        was not complete.

 

(b)     The nature of the coral surrounding the Marianas Islands is that of a           very high density sand-cemented coral which does not lend itself to           disintegration. Thus, on charging it and blasting, the result is an area of craters and free coral boulders which require further         blasting or removal by earth moving equipment.

 

On D plus 3 morning, powder was placed in an attempt to form an LST ramp 100 yard (sic) wide and thirty-five yards deep. This operation was fairly successful although the ramp was rough and somewhat irregular.

 

Experience in blasting coral for this operation indicates the inability to improve the face of a sloping hard coral reef for an LST ramp. While blasting is extremely effective in clearing boulders or coral beach and roughly shearing the lip off an abrupt reef, any demolition on a sloping reef worn smooth by wind, water and tidal action, will result only in scattered craters and the formation of a coral lip that in itself constitutes obstacles, unless the scattered debris is cleared by earth moving equipment.

 

Miscellaneous blasting of coral heads and boulders along the beaches to clear roads for LVTs and trucks along the reef tops and buoying and flagging positions along the reef lip for LST approaches, completed the work required of Team SEVEN on the Saipan operation.

 

This operation was the first in the Pacific Theater of operations which fully committed Underwater Demolition. Consequently much was learned there about the various tactics which constitute an Underwater Demolition operation. These lessons could not have been foreseen and were not foreseen by the various training staffs to which Team SEVEN had been exposed.

 

It can be very easily seen that in order for a Demolition Team to conduct its work successfully with a minimum amount of exposure of it's personnel to enemy intimidation, the enemy must be kept in abeyance. This can be done, by a fire support which closely co-ordinates itself with the work of a Demolition Team. As a result of the Saipan operation it was found expedient to recommend and, realize a fire support, the source of which is as close to the beach as possible and one in which the use of rapid fire small caliber guns is emphasized. Further it was thought feasible to assign members of Underwater Demolition Teams directly to fire support ships to act as liaison between the two factions during the course of an operation and to acquaint the gunnery officers aboard these ships with the type of fire which would best serve demolition.

 

Much was learned too about the communication network of a Demolition Team in operation. The striking point here was that radio communication between the CLPRs and the fire support ships should be direct and fire calling should be familiar to all officers of a team. Also it was learned that communication between swimmers and LCPR personnel was impractical, so such communication was discontinued.

 

The use of swimmers and LCPRs was mildly revolutionized as a result of the Saipan operation. As stated heretofore, all four platoons of the team were assigned a beach and all personnel of each platoon were assigned duty within that platoon. It later became apparent that should anyone of these LCPRs become a casualty by enemy fire or causes inherent in machinery, there would be no help or relief for it without imposing upon another LCPR which was busily engaged on another beach. Thus it was felt expedient to embody in plans of future operations provisions for reserve and stand-by LCPRs whose sole function would be that of aiding operational LCPRs which had become immobilized. Further, swimmers were redistributed in the LCPRs in accordance with the "operational reserve" plan. It was felt that fewer swimmers would be used in an operation proper and the remaining swimmers allocated to the reserve LCPRs as a reserve swimmers again in case of an operational LCPR becoming immobilized.

 

It was also apparent that immobility of landing craft was an invitation to disaster and manuevers (sic) of LCPRs were initiated and employed by the coxswain. Such, for example, as approaching and leaving the beach in a zig-zag, picking up swimmers while in motion at a speed of up to 2200 RPMS, retreating from the beach after the swimmers had disembarked, and performing figure eights at high speed until the swimmers were prepared to be retrieved.

 

With the necessity for this continuous speed came the need for methods of discharging and retrieving swimmers while the LCPR was moving. The use of a rubber boat tied along the seaward side of an LCPR had been initiated at Maui; however, the problem was to get an exhausted swimmer into it while going 2200 RPH. This problem was solved by the rigging of a stiff line with two loops, one at each end, having an overall length of three feet. One loop was to be retained in the hands of a man placed in the rubber boat.

 

The second loop was to be caught by the hands of the swimmer being retrived (sic). The swimmer had thus made contact with the rubber boat via the man in it and the double looped line and was pulled into it with very little difficulty.

 

Much was learned about the gunnery required on an LCPR being employed in an Underwater Demolition operation. On the Saipan operation the gunnery consisted of two thirty caliber maching (sic) guns mounted in the two forward machine gun mounts and a tommy gun operated by a gunner gositioned (sic) between these in the rqmp (sic) of the LCPR. Later operations saw the inclusion of a bow and stern fifty caliber maching (sic) gun, in addition to the two thirty caliber machine guns.

 

All of the suggestions, recommendations, and changes made apparent by Team SEVEN's operation on Saipan were made on future operations by that team and were incorporated into the Underwater Demolition scheme to become standard procedure in all Underwater Demolition operations in the Pacific. They were embodied in the training program at Maui when Team SEVEN was sent their (sic) later to train new teams coming to the Pacific.

 

The interim of time between the Operation of Underwater Demolition Team SEVEN on Saipan and that on Tiniam it's next operation, was spent, for the main part, in confinement aboard the APD as it carried out it's duties of screening and picketing.

 

On 22 June, the team was transferred to the U.S.S. STRINGHAN, (APD-6). There on 10 July, a night reconnaissance was ordered off the Yellow Beaches along the northeast coast of Tinian in conjunction with a beach reconnaissance made by Company A of the 5th Amphibious Reconnaissance Battalion of the Marines.

 

Before embarking on the combat reconnaissance of Yellow Beaches Captain, now Major, James L. JONES, Commanding Officer of the Marine contingent and Lieutenant BURKE were warned not to alert the beaches, so Lieutenant BURKE ordered that should signs of the beach having been alerted present themselves, personnel shall retire from the beach. As the swimmers on this operation were debarking from their rubber boats which had been brought into within 500 yards from the beach, several shots were heard which gave the impression that the beach had been alerted and that the enemy knew of our presence. In accordance with orders the swim personnel returned to the rubber boats to the APD. The Marine contingent, however, despite the seeming alert proceeded with no casualties. Since the mission of the Marine contingent overlapped that the Team SEVEN, the information desired was satisfactorily obtained and disseminated to interested parties.

 

The main operation by Underwater Demolition Team Seven on Tinian was on 23 July 1944 and was a diversionary daylight reconnaissance of a barrier reef off Red, Green, and Blue Beaches for a total of 2500 yards. These beaches were just off Sunharin Town and it was hoped to make the enemy believe that this was where the anticipated landings, which were to be made the following day, would be staged. The plans for the diversionary reconnaissance embodied many of the recommendations developed as a result of the operation on Saipan. For this operation only three LCPRs were used as operational craft, and from each of these only seven swimmers were dropped. A fourth boat located a thousand yards from the reef was dispatched (sic) as a reserve and standby boat and in this were present seven standby swimmers. The curtain of gunfire and air strikes were described as superb in accomplishing their purpose. The effectiveness of this support can be demonstrated by stating that the only enemy fire encountered was sniper fire and this, upon investigating, totaled three shots in number. Large caliber naval fire at known targets combined with steady forty millimeter fire into the beach and above the water's edge effectively covered the operation. The reef which was reconnoitered on this operation was of the barrier type and extended out from the beach proper from 500 to 1000 yards. Since this was only a diversionary feint, swimmers were ordered to go no closer to shore than the inner edge of the reef. One natural channel and a questionable natural small boat channel presented themselves on aerial photographs and mapes (sic). Certain swimmers were designated to investigate the former for it's navigability and freeness of obstructions and mines and the latter for its questionable being. This channel was not found and proved to be a misinterpretation of the photographs. The reef was found to be a flat, relatively smooth top reef which would present no obstruction to passage of LVTs or DUKWs. No obstacles or mines were found after forty-five minutes of reconnoitering by the swimmers. No casualties were suffered.

 

The post-assault work of Team SEVEN commenced on D-Day. A thorough search for anti-boat mines off the fringing reefs on Beaches white One and Two was made. No mines were found, but unexploded rockets and bombs were removed to the beach. Personnel encountered enemy machine gun fire but no casualties were incurred. On D plus 1 and D plus 2 pontoons were placed on While (sic) one and White Two. The Team aided in the placing of these pontoons, and some demolition on the beach was necessary.

 

The work at Tinian completed, Team SEVEN, began dreaming about coming back to the States. A transrer of personnel from the team and the U.S.S. STRINGHAM to Team FIVE and the U.S.S. GILMER was made at this time. Arrival at Espirito was marked by the team’s shift to the U.S.S. ELMORE (APA-42) for immediate transportation to Turner City on Florida Island. This destination was reached on 24 August. Supposedly the team was to reconition (sic) here for its approaching operation on the island of Pelilieu of the Palau group in the Western Carolines; but the tropical climate did not lend itself to exertion. On 6 September the STRINGHAM picked up the team, leaving for Manus, where the task force was gathering. During the trip, SEVEN prepared for its operation.

 

Just prior to the team's commencing its operation on 23 July, the

STRINGHAM and two destroyers were ordered to stand-by the U.S.S. NOA (APD) carrying Underwater Demolition Team ABLE. This ship had been rammed and was sinking, necessitiating (sic)  a submarine screen while its peronnel (sic) were transferred. After this delay, at 1100, three LCPRS were put in the water to make the reconnaissance, the fourth having been damaged while it was being lowered. The plan embodied the idea of using as few swimmers as possible, of providing for standby and reserve LCPRs and swimmers, of using direct communication between LCPRs and fire-support ships, of maintaining constant mobility of (sic)

 

At this time the tide was low, exposing the reef for 100 yards from the beach, thus limiting the area in which the swimmers could safely investigate. As a consequence, it was recommended that whereever (sic)  possible, future reconnaissances (sic) should be conducted at high tides.

 

Results showed that the reef was smooth and flat with a gentle slope to the beach, with steel tripods and rows of wooden posts about seventy-five yards from the beach. Log barriers and concrete cribs were reported on the beach about thirty yards above the high water mark.

 

On the night of D minus 1, 14 September, it was decided to remove the obstacles on the beach. Poor planning and excessive manpower coupled with the inevitable confusion of night work resulted in a disappointing operation On D-Day morning, however, three team officers were dispatched with the charts showing the condition of the beaches at that time. Unfortunately the STRINGHAM disembarked these men so far from the beaches off which the control vessels were located that the information was too late in arriving. As the data that Demolition accumulates is of no practical value unless provisions are made to make it available to the assault wave commanders before they are committed, it was recommended that such provisions be made even if Demolition Teams had to operate as many as five days previous to the invasion.

 

At 1030 on D-Day one LCPR with personnel and explosives reported to the Beachmaster for duty. The unit also laid anchorage buoys. On D plus 3 a . reconnaissance on Orange Three Beach was conducted for anit-tank mines. None were found. The ramainder (sic) of the post-assault work was performed on the southwest side of the island on Scarlet Beaches One, Two and Three, and 200 yards of Purple Beach.

 

At 1500 on D plus 3 a reconnaissance of Scarlet Three reported finding thirty-nine J-l3 mines and many obstacles. These latter consisted of imbedded steel and concreted rails and steel tetahedrons (sic).  The first were twenty pounds, light-gage rails. Planted about five feet high. Those of concrete gate.  As a consequence, it was recommended that wherever possible, future reconnaisences (sic) should be conducted at high tides.

 

After a ten day inter-island leave. it was assigned to the base as the training team. During the team's absence many improvements had been made on the base both in living conditions and the quality and diversification of the training. Teams ELEVEN through SIXTEEN were trained at the hands of Team SEVEN personnel, thus receiving the benefit of that outfits experiences and mistakes as have been outlined above. Meanwhile, the team itself suffered many personnel changes, the most important of which was the departure of lieutenant (jg) ONDERDONK to become Commanding Officer of Team FOURTEEN. Lieutenant (jg) ROBBINS took over as Executive Officer.

 

During January 1945, the team itself went through an advanced training and reconditioning program before being ordered out on 14 February to Leyte Gulf, the staging area for the Okinawa invasion, aboard the U.S.S. HOPPING (APD-5l).

 

In San Pedor Bay, Leyte Gulf, one rehearsal for this operation was held. Then on 23 March, the task fleet left for Okinawa. Here the team was scheduled to make a reconnaissance of Yellow Beaches on the western side of the island on Leve minus 4 day; however, to enable the minesweepers to complete their mission, this was delayed for one day until 29 March.

 

The plans provided for one pair of swimmers every 100 yards on a 1200 yard beach to swim to the high water mark. In addition, four swimmers were assigned to swim across the reef parallel to the beach. In order to have as few landing craft as possible approach the beach, only two were used to drop the swimmers. One additional boat with the reserve swimmers was held in readiness 2000 yards from the beach. The primary fire support for this operation was provided by LCI(G)s firing forty milimeter (sic)  shells at the beach. This, in turn was backed by destroyers, cruisers, battleships and air combat patrols Entering (sic) the water at high tide in a flat and caml (sic) sea, the swimmers approached the beach facing the sun.

 

The information brought back by the swimmers was quite comprehensive. It was found that LVTs and DUKWs could cross the gradually sloping reef which was composed of hard live coral covered with sand. Only a few coral heads were found; on Yellow One, however, fissures would prevent landing craft from unloading vehicles on the reef. Yellow Two and Three were excellent for both LSTs and LCMs. The beaches themselves were well-defended with pillboxes and gun positions, but no opesition (sic) was encountered other than sporadic sniper fire.

 

Three rows of wooden posts, imbedded in the reef, were in place across Yellow Two Beach, approximately forty yards from the high water mark. It was estimated that there were 200 of these posts, averaging six inches in diameter and six feet high, wedged into holes on the reef. From the amount of sea growth of the posts, it was apparent they had been in the water for along (sic) time. Although the team reported that these did not constitute an obstacle to assault waves mounted in LVTs, it was decided, nevertheless, to return the following day to destroy them.

 

This operation w s (sic) carried out, using one block of tetrytol for each post. During the time the men were working, there was no opposition from the beach. The deep fire support was presummably (sic) good but the close-in fire of forty milimeter (sic)  guns was erratic one of the team's swimmers being wounded by this fire. Many of the men were affected by the cold water, suffering cramps.

 

Results showed that the reef was smooth and flat with a gentle slope to the beach, with steel tripods and rows of wooden posts about seventy-five yards from the beach. Log barriers and concrete cribs were reported on the beach about thirty yards above the high water mark.

 

On the night of D minus 1, 14 September, it was decided to remove the obstacles on the beach. Poor planning and excessive manpower coupled with the inevitable confusion of night work resulted in a disappointing operation On D-Day morning, however, three team officers were dispatched with the charts showing the condition of the beaches at that time. Unfortunately the STRINGHAM disembarked these men so far from the beaches off which the control vessels were located that the information was too late in arriving. As the data that Demolition accumulates is of no practical value unless provisions are made to make it available to the assault wave commanders before they are committed, it was recommended that such provisions be made even if Demolition Teams had to operate as many as five days previous to the invasion.

 

At 1030 on D-Day one LCPR with personnel and explosives reported to the Beachmaster for duty. The unit also laid anchorage buoys. On D plus 3 a reconnaissance on Orange Three Beach was conducted for anit-tank mines. None were found. The ramainder (sic) of the post-assault work was performed on the southwest side of the island on Scarlet Beaches One, Two and Three, and 200 yards of Purple Beach.

 

At 1500 on D plus 3 a reconnaissance of Scarlet Three reported finding thirty-nine J-l3 mines and many obstacles. These latter consisted of imbedded steel and concreted rails and steel tetahedrons (sic).  The first were twenty pounds, light-gage rails, planted about five feet high. Those of concrete measured six inches by six inches by five feet. The tetahedrons were seven feet by seven feet and constructed of light weight pipe or reinforced bars. In two days, the team succeed (sic) in clearing this area.

 

Scarlet Beaches One and Two revealed obstacles consisting of the same size concreted rails, as on Three, placed about fifteen feet aprt (sic) with barbed wire and plain wire strung among them. Around every third or fourh rail were wood tetahedrons (sic) filled with rocks and coral. More mines were also located. Heavy loading was necessary on large obstacles, but the demolition was successful.

 

The 200 yards of Purple Beach disclosed three parallel rows of obstacles. The first composed of logs; the second the shoreward of the first was composed of steel rails; and the third was composed of reinforced concrete posts. Single blocks of tetrytol on each obstruction were sufficient to destroy them.

 

On 21 September, the STRINGHAM left for Manus. There the team was ordered to transfer its powder to the U.S.S. CLEMSON, an APD, carrying team SIX. While the two ships were tied to ether, (sic) carrying out this order, a fire started spreading over the fantails of both. Quickly, loose tetrytol was heaved over the sides and the ships separated. Fortunately the fires were both brought under control before extending to the holds. The cause was never determined. The next day, the STRINGHAM left for Pearl Habor, and on 15 October, team SEVEN was back on Maui.

 

As usual, on the day the invasion, some of men from the team led the assault waves into the beaches. On the following day a reconnaissance was conducted of Yellow Three Beach and for a distance of some 200 yards up a river. No demolition work was considered necessary.

 

During the next four days additional reconnaissances (sic) were made of White, Baker, Purple Baker and Brown Baker, all behind the fromt (sic) lines, to ascertain Their (sic) capacity for the unloading of supplies. There, on 7 April, another reconnaissance was carried out on Red Baker Three Beach, on Tsingeu Shima, three days before the invasion of that islet. Excellent fire support was received from two destroyers, the U.S.S. MORRISON and U.S.S. LAWS. No enemy fire was encountered nor were there any casualties.

 

While the HOPPING was still on screening duty off Tsugen Shima, on 9 April, shore batteries opened fire with armor-piercing projectiles. One of these exploded in the troop quarters, resulting in nine demolition casualties, one of whom died. The ship was able to leave the next day for Ulithi Atoll in the Caroline Islands, where the team was put ashore for five weeks. Finally aboard the U.S.S. JEAN LAFITTE, the team was transported back to San Francisco, where each man was granted thirty days leave.

 

Reporting in to Oceanside, California on 11 August, the team was most disappointed, when it learne (sic) that it was to go back to sea again in spite of Japan’s impending surrender. Loaded aboard the U.S.S. AUMAN (APD-117), The (sic) team left, nevertheless. Lieutenant ROBBINS was now Commanding Officer, as (sic) Lieutenant Commander BURKE was on the staff.

 

On 4 September, the AUMAN reached Tokyo Bay. There for ten days no work was engaged in, so the team recieved (sic) occasional liberty ashore. On the 14th the team was given orders to proceed to Sundai about 185 miles north along the east coast of Honsho there to conduct a reconnaissance. Both this, and a scouting party, which looked for roads for the incoming troops, were dispatched the next morning. The information attained was compiled and sent to C.T.G. 322.  Returning to Tokyo Bay, the AUMAN left for the United States on 21 September.

 

Upon arrival at San diego  (sic) on 13 October, the team was stationed at the Naval Amphibious Base at Coronado, where post-was (sic) demolition was setting up its headquarters. Two weeks later, Team SEVEN was completely decommissioned.

Birger Stromsheim  10/11/1911—11/10/2012.  Birger was not a Frog but performed a great Frog type operation in 1943 when he and his crew of fellow Norwegians destroyed the Norsk Hydro plant. The plant made “heavy water” (deuterium oxide) critical to the German effort to create the atomic chain reaction that would lead to the Nazi bomb. The film The Heroes of Telemark (Kirk Douglas and Richard Harris--1965) portrayed these activities. He was heavily decorated for his part in the Norwegian resistance.

 

Maxine Otte:  Walt Otte’s wife Maxine passed away in early November 2012 from a longstanding heart condition. Our condolences go out to our comrade Walt.

 

 

 

 

 

 

 

 

UDT THREE -- PARTICIPATION IN MINE CLEARANCE

WONSAN, KOREA NOVEMBER 1950

 

Mack Boynton

 

[EDITOR’S NOTE: Mack Boynton has contributed another interesting historical account of Frogs in Korea. We invite more such stories. First hand stories add a dimension to our history that has been neglected.]

 

*****

 

The great success of the Inchon landing, led Mac Arthur to order a second amphibious assault targeting Wonsan on Korea's east coast.  As the Inchon landing was drawing to a close, UDT ONE was ordered to remain for harbor salvage and clearance, and UDT THREE received orders to proceed to Wonsan for the pre-assault reconnaissance.  The North Koreans had learned a bitter lesson by failing to mine the Inchon harbor, and were not going to be caught in that situation again. 

 

UDT THREE commenced operations on 10 October, ten days before the scheduled amphibious landing.  On the initial reconnaissance we discovered the approaches to the landing beaches, as well as the entire harbor, were well saturated with moored mines.  We were fortunate to have the services of a “chopper” from the USS ROCHESTER that could spot the mines which were at about 15 foot depth and visible in the clear water.  The USS DIACHENKO (APD 123) had an ample supply of the mine devices that clipped on to the horn of the mine, and when activated by bending would fire, and in turn, fire the moored mine.  This was the first time I had the opportunity to use these devices, which I suspect, were left over from WWII.  We anticipated that magnetic mines would be found, and this came true on 18 October when the South Korean YMS516 struck one of them and was destroyed.

 

The water was extremely cold and the old "dry suits" left much to be desired, but our operations continued while awaiting the arrival of the “minesweeps”.  The landing was postponed from 20 October to 26 October.  The entire landing force composed of the First Marine Division came to a complete stop. 

 

UDT THREE was overjoyed to see the minesweeps, PIRATE (AM 277) and PLEDGE (AM 275) come steaming into the mined area with all flags flying and all sweep gear engaged on 12 October.  UDT small boats were off their port beam; number one boat with Lt. Harry Nowak in charge, and I was in charge of number two boat -- as they passed us close aboard we waved and cheered, and they responded by doing the same.  We were in a position to see the swept mines pop to the surface and they were destroyed by gunfire from the sweeps.

 

The PIRATE was the first vessel mined, it appeared to have made contact with a mine on the starboard side and was listing to starboard and sinking rapidly.  To make matters worse, a shore battery commenced firing upon her.  By the time Harry's boat came along side to pick up wounded and survivors, the fantail was awash.  My boat headed for the PLEDGE which was mined shortly after the PIRATE.  I went to the bridge where I found bodies, but no survivors.  It appeared that the bridge took a direct hit by the shore battery leaving no one alive.  My boat loaded many wounded, and searched other areas of the ship for any survivors, and collected “dog-tags” from those who were dead as we only had room on our small boat for survivors. 

 

The PLEDGE was also sinking, but at a slower rate than the PIRATE.  We watched as PIRATE rolled over exposing most of the keel.  Number one boat proceeded to take PIRATE's survivors to one of the other ships.  I departed the PIRATE and took the survivors and wounded to the USS INCREDIBLE. 

 

I returned to the DIACHENKO and picked about twelve UDT men, all well armed -- including grenades and demolition packs.  I had observed a shore battery high on a ridge while they were firing upon the PIRATE and PLEDGE and proceeded to a point on the beach where I could not be observed by the battery.  I picked two point men and we proceeded up the ridge about a mile distance, to the shore battery.  We came upon the North Korean gun crew who were busy getting their wheeled guns ready for departure and were not aware of our presence.  We tossed grenades and opened fire.  A fire fight ensued -- all the North Koreans were killed!  We put demolition charges on all of their guns.  We found harbor charts that were marked off in grids with ranges and elevations giving complete and accurate fire control to the harbor area that made the PIRATE and PLEDGE sitting ducks. 

 

Following the sinking of the PIRATE and PLEDGE, UDT was ordered, if feasible, to dive on the sunken minesweeps to recover any classified material.  I was the only Master Diver in the team and I selected George Gionnotti as a diving partner.  The ships were in about 100 feet of water.  We made the dive and discovered that the shore battery had demolished most of the area we were concerned about.  COMSERVPAC ordered a salvage ship (ARS)  to make a four point moor over the target area and to make surveys of the sunken ships.

 

UDT THREE was relieved at Wonsan by UDT ONEUDT THREE was ordered to proceed north to make pre-assault recons at Iwon, and beaches far behind enemy lines. 

 

Mac Arthur was on his way...

BITS AND PIECES FROM THE FORGOTTEN WAR

FROGMEN PREPARING FOR RAID – preparing firing caps, time fuse and prima cord while sitting on 60 pd. packs of TNT - (God, I hope OSHA isn’t watching)

 

Preface:

 

At this age memories are fleeting at best – as they flash by I keep scribbling them down on paper because somehow I keep thinking they may jog the memory of those who may have forgotten - and pray God will help us and America to remember…

A SPOOKY DAY FOR APD DIACHENKO AND THE TEAM

 

The day APD Diachenko (or it could have been the Wantuck or the Begor- my memory being what it is) was straddled by shells from a communist shore battery was spooky at best. What made it more so was the fact that my UDT Team was aboard with all their blasting paraphernalia, including many pounds of TNT stashed in the bowels of the little ship.

  

As I remember we were in the middle of a series of raids along the West Coast of Korea. We had gone in that night, via rubber boats, to blow a railroad bridge. The communist opened up on us before we got to the beach; evidently this was an important facility and they had set up an exceptionally stout defensive posture to protect it.

  

We abandoned the operation, which was standard procedure if we drew fire before reaching the beach, scurried back to the ship and went to bed, thinking the ship would get underway to our next objective.

  

At daylight the next morning a loud “Bang” shook us out of bed – on rushing to the fantail in our skivvies we found the ship was shooting at the  bridge. They were trying to knock the bridge out with the ship’s forward 5-inch gun. We understood the ship’s Captain had made the decision to try his luck and had run circles all night approaching the bridge at daylight.

 

It was a beautiful day with fleece clouds decorating the skies; we were shouting and yelling encouragement to the gun crew as they peppered shell after shell at the bridge. The ship’s bridge was screaming at us, “Get the hell off the deck, we’re at General Quarters”.

 

Suddenly a geyser of spray erupted just 50 yard short of the ship, we were all thinking our gunners had made a terrible shot, when another geyser blossomed just seaward of the ship. It dawned on all of us at the same time the ship had been bracketed by a shore battery. The wild stampede of a bunch of half-naked Frogs to get inside off the open deck should have been recorded by film. Of course it sure as hell was not funny at the time – but now, looking back on it, it seems hilarious.

 

The little ship set down in the stern like a scared goose as the below deck guys cranked on flank speed – and we hauled ass out of there like a scalded hound.

  

After the ship had scrambled out of danger some of us began peeking out the hatch to see what was going on. As we watched, the gun crew swiveled the 5-inch gun and started walking shells up the mountain where the communist battery was located. When they got to the top they put it on full automatic and laid about six rapid rounds right on top of the enemy gun.

  

The ship’s gun crew had done no damage to the bridge, but knocking the enemy gun out had saved face for them - however we could find no solace for ourselves. Compounding our problems, we received verbal abuse like only a salty old Chief Boats can do it - for going on deck during General Quarters.

 

 

THE WAR WITHIN A WAR

 

In the Japanese port of Yokosuka the U.S. Marines had set up an MP station prior to the Korean War. In those days they had built a furious reputation for being “hard asses”– and the sailors who went ashore in that port had to “Walk On Eggs”, as the saying goes. Many sailors, who went ashore in those days and got a bit out of line, had felt the wrath of that MP aggressiveness.

  

When the war started, suddenly the port was filled with sailors and the Marine MP’s added to their staff, determined to keep their “Iron Ass Policy” intact.

  

UDT Teams arrived early and began using that port as a debarkation point to raid the Korean coastal transportation routes. The Teams would insert from Yokosuka and make from 4 to 6 preplanned raids, then come back to Camp McGill (just out of Yokosuka) to plan and train for the next series. After repeating this action a number of times – and getting shot up on a number of operations, the guys began to question their longevity on this earth. So its not surprising that after a while they began letting it all hang out when returning to Yokosuka in one piece.

  

Of course that put them on a head-on collision course with the iron ass MPs. As the number of incidences increased we began to hate those MPs more than the communists and began spending as much time planning operations against them as we did against the communists.

 

Some of those operations were ingenious, and too many of them occurred to tell here – however, this one operation caused a death and that seemed to curb the violence on both sides.

  

The guys had planned an operation where they would sucker the MPs into raiding a certain bar on the outskirts of the city. The success of the plan depended on the MPs rushing to the location in their vehicles and storming inside. When they did, our guys would steal their vehicles and drive away.

  

The plan worked like a charm. On one occasion as the MPs rushed into the bar, a Frog jumped into one of their vehicles and took off. As the Frog took off, the Sergeant of the MP detail was driving up in a jeep. He saw his vehicle speeding off with a sailor at the wheel and took off after it. The Frog was racing into the foothills outside the city with the jeep in hot pursuit – our Frog did not make a curve and ran off a 200-foot cliff.

 

With this Frog’s death, the war within a war came to a screeching halt.

 

Postscript:

  

I did not include the Frog’s name in this article because driving off a cliff running from Marine MPs is not the most glorious way to die in a war. However, he will be remembered as a true hero by all of us. He had previously been awarded the Bronze Star and other awards for heroic action at Wonsan.

  

Even at this late date, if you were a Marine MP in Yokosuka during the early 50’s – walk softly around us….

Seeking Information:

 

I am doing research for a book featuring Korean War participants from the upper-central states. I’ve been researching Lt. Philip Mastor, from Bemidji, MN, for inclusion in the book. He died “under honorable conditions” in Japan on August 21, 1951.

 

Mastor was in UDT-21 in WWII, and he was reactivated for Korea in August, 1950

 

I haven’t been able to find family members or war buddies so far. His father was from Greece.

 

Thanks,
