(2) Unload the ships simultaneously in a minimum

of time bo thoy could withdraw.

(3) Obtain maximum dispersal of men and supplies consistent with tactical safety for protection against

air attack.

(4) Be so disposed as to develop without delay a beachhead in whatever direction ground reconnaissancedictated after landing.

(5) Be prepared to resist immediately a seaborne attack.,and/or counter landing.

(6) Provide air defonso of the beachhead as soon aspracticable.

The

considerations listeddictated the following

deolsions:

(1) To embark three task units in the ships allotted,two to be reinforced Infantry regiments of 4Landing Teams each, and the third basically anti-aircraft artillery of the 3d Def Bn. With eachof these units were assigned the detachments ofEngineer, *ir,llaval Base, Signal and 3erviceTrooos whose mission was the Immediate developmentof the ;»ir and Haval Base facilities.

(2) To restrict the loading of the shloa to about 500tons each in order to be able to unload withinfive to six hours total elapsod time.

(3 ) To land all elements simultaneously, combatant

elements covering non-combatant elements.(4) To seize a broad shallow beachhead, initially,

in order to contain immediately whatever Japanesedefenses had been Installed, to institute vigorousterrain reconnaissance inland fo r location ofroutes of ingress and airfield sites, and to dis-perse troops and stores against air attack.

(5) To be prepared to shift elements laterally withoutdelay in order, either to reinforce, or to developthe beachhead to the direction reconnaissancedictated*

(6) To bo prepared to organize beach and air defensesimmediately on landing.

(7)To transport to impress *£usta Bay area theremaining echelons of the Division as rapidlyas the availability of ships and distance permitted.

The plan as completed divided the equipment and sulliesor toe organization into three categories:

-m Those items essential to live and fight for ten

days. This included at least ten days rations,3 units of fire for the weapons embarked,^nd^fuel fo r the same period.

B Those items required fo r the continuation ofcombat, additional munition*, rations, fuel,

-

and the engineering tools and equipment for the

development of the beachhead area and airfields**

C All other items no t Included in or B.

Category A was to accompany the assault echelon,Category B vac to be forwarded with subsequent echelons, andCategory C was to remain stored with the rear eohelon on Guadalcanal pending further instructions. Thus the equipment and suppliescarried initiallycame within the tonnage limitation* imposed fortactioal safety of the transports.

The plan of landing was to employ twelve beaches, oneper ship, eleven extending west from CLiPg MROKIHA some 8000 yardsand one on the north (inner) shore of FUHU*Jp I?JUnjJP *11 elementswere to land simultaneously, the 3d Mar reinforced by the RaiderRegiment (less one Landing Team) in the right seotor (6 beaches),

(Raider)the 9th Mar reinforced by on e LandlxurXoam in the loftsector (5 beaohes), and on PUKLUIA laLiJip (1 beach). Two groupsof the 3d Def Bn were to land in the right seotor and two in theleft sector. Each combat team was to overrun and destroy allenemy beach defenses, seise an initial shallow beachhead andinstitute vigorous reoonnalssanoe Immediately to the front andflanks, meanwhile unloading the ships as rapidly as possible andinstalling beach defenses, and prepared to shift laterally ineither direction.

2. REHEARSAL.

With the completion of the plan of attack, the CombatTeams began embarkation at £Utt&ftfc£ftUab

°*313 October, 1943, and

proceeded to ETaTE. flfflfflHpigg. where complete rehearsal of thelanding was exeouted. The Defense Bn task unit exercised at

fffftPnfcfrftlinl «U foroes rendezvoused enroute to &EMBSUU&

3.

The initial landing was executed as originally plannedbut subsequent disposition of tactioal units ashore was precipi-tated by the faot that stronger resistance than expected was meton the right flank. Beach and surf conditions to the west of theKOROMOKIIURIVER were found to be unsuitable for oontlnued use aslanding beaches (some 70 landing oraft broaohed on these beaohes-D-day), and ground reoonnalssanoe disclosed that the llUM^»Mlm>PIVj» TiUILarea constituted the main overland access to our vitalbeachhead area fo r the enemy, as it became apparent that noimmediate enemy oontaot was forthcoming on the left (west) flank,it was deolded to exeoute the redlspostlon of units as previously

Therefore, the (2)lanned for consolidation of the beachhead.left Landing Teams, Ist and 2d Bns, 9th Mar, ware moved in succession to the right (fast) sector. The right LT, Ist Bn 3d Kar,

wae brought into reserve in the left sector and the oenter LT,2d Bn 3d Mar, moved to the right of the left sector. As of 5Hoy 43, the disposition of troops consisted of five battalionson a limited beachhead line, a battalion in reserve in the leftseotor, a Aaider battalion plus one Co with Aegtl Hq in reservein the right seotor, a Raldsr company blocking the PjVA Tftj^fcbeyond the beachhead, and a Raider battalion less two (2 ) ooapanlesoccupying PURIUTj* iaLnHD.

(3) The great difficulties encountered in road construction and ingress through swamps for supplyroutes to the troops, Special precautions had to

be exercised to the ond that our forces be notadvanced beyond our means of supply and evacuation*

as the beachhead was being extended* Japanese resistance wasdeveloped to the north and east of the PIVA HIYSI forks and northof the E*3T WEST TRAIL, The first indication of enemy resistancein strength appeared on 20 Nov 43. This developed into theBATTLE Cg Ply* rOrtKS which was continued on through 25 Hoy 43 bythe 3d Har, reinforced during the latter phases by elements ofthe 2d A&lder Aegt, the 9th Mar, and the 21st Mar. artillery wasconstantly employed in increasing force until on 24 lloy 43, sevenbattalions fired the preparation for the 3d «tar attack. Thisattack destroyed the major portion of the enemy foroe (estimatedas a relnforoed regiment) and completely routed the remainder,most of whom fled well to the 6ast of the TOaOCH* RIVZR.

On 25 Hoy 43 the Ist Bn 9th Mar and six companies ofthe 2d Haider Regt passed through the 34 Mar and, against l ightretiring resistance, occupied the hillmass east of the PIVA RIVKRdominating the EfJR VXBT TRAIL.

whloh had beenonly lightly

engaged atany

time so far, to take over an active subseotor and the 3d Mar tooocupy the relatively quiet sector on the right (south) flank ofthe beachhead. This exohange of sectors was initiated on 24 Uov43 and oompleted 26 Hoy 43. The 21st Mar remained in the centereubseotor and the 2d Balder Aegt returned to Corps town; The3d Mar badly depleted by battle casualties, sickness, and exhaustion, was relnforoed in Its new seotor by the Ist Bn, 145thXnf (Begtl reterw) and other special units.

When reeonnalssanoe disclosed that the enemy was no toooupying the hillmass Just west of the TOaaciliA RIVER, eventhough supply and evacuation would be most dimoult, the CO,3d Mar- -Dlv, initiated advance to and occupation of that generalline Hills 1000, 600, and 500, and the high ridge runningwestward from Hil l1000. The first stsp was the occupation ofan OPLR by: the 3d Parachute Bn and units of the 9th, 21st and 3d

Marines, pending construction of amphibian tractor routes forsupply and evacuation through the dense Jungle swamp*. On 10Deo 45 the three Infantry regiments advanced to and occupiedthe FBL without incident. In the meantime, however, the 3dParachute Bn, outpostlng Hil l1000 and a portion of the sub-sector to be oooupied by the 2ist Marines, had beoome engagedwith an enemy force, estimated as a reinforced company, stronglyentrenched on the east slope (nose) of HUI 1000. After repeatedattacks by units of the 21st Mar, supported by artillery and doseair bombardment, this foroe was eliminated on evening of 18he _Deo 43. '_. ,*-» IT^

Detailed aooounts of the various operations may befound in reports by organisations of 3d Mar Div, enclosed herewith*

The unloading of the ships transporting and accompany-ways.ng initial landings affects the tactioal plan in numerous

In general there is need for employing, during the unloadingperiod, approximately 33 l/$2 of the personnel embarked in orderto attain the maximum eff ioienoy possible and thereby to reducethe unloading time to a minimum, Beoause a oertain percent ofthis labor Is performed by naval, personnel who have no combatmieelona at the moment, tint total result affects the combattroops to the extent of at least 2% f of the total effectivestrength. There are two solutions to this labor problem, themost obvious one being to transport labor troops whose sole pur-pose is to handle the details of the unloading. This is not

entirely satisfactory inasmuch as it oauses the landing of elementswhich are not suitable for ground oombet at a time when they maybe a hindrance to the operation. Further, their Maintenance and•apply creates an additional burden on those funotlons withoutadding anything to the ef flolenoy of the foroe landed Immediatelythat the unleadias le oompleteoV The following solution wouldalso provide the vital labor. When the estimate of the strengthneoeeeary to aocompllsh the oombat mission has been determine!,the eeatatant unite should have their strength increased tX& inthe ranks of private and private first olaae or organised replace-ments should be embarked to the strength of 25^ of the oombattroops. This additional strength would provide the shore partylabor initiallywithout Jeopardising tactioal strength and unityof ooabat organiaations. Oji the completion of the unloading thispersonnel le iismediately available for replacement of oombatlosses, for garrison or other duties, or may be returned to rearareas in same ships.

When kXA's are employed with the assault echelon, theshore party organisation should be embarked in «PD*s, LSD's orLST's and accompany the assault. aKA's cannot accommodate suffi-cient personnel aboard to constitute their own shore parties, andAfta's.aay accommodate only their own in addition to the LandingTeam embarked, otherwise, the Landing Team suffers such a drainon its personnel that its oombat offeotiveneM «*4mmVßrefe-

In the execution of the landing at TQBflgHa the soundness of this plan wasproved, the result being that reserve force continued to be In-creased in the area of contact during the early phaees of aotlonthere.

The value of the early and continued employment ofBases* artillery fire cannot be overestimated. It is the oneam of the ground foroee with which the eoaaandor oan influence

the aetlon over his entire front without the movement of troops.The largest nuaber of batteries possible, consistent with thesue of the landing force, should be in the initial landing force,along with the proper artillery heedquartere to Bake centralisedtiro oontrol possible*

'tfhero units not ordinarily a part of the Division are

attached for a particular operation, these units should be attachedwell in advance of D-Day. Shis is necessary In order that boththe Division and special units asy becone acquainted with eachother and execute their initial planning together.

(1) It vps found that the personnel authorized forthe Aerial Photo Interpretation Unit was in exoeee of thatrequired. It la considered that tvo offioers and six en-*

listed (API) plus one clerk can adequately perform thenecessary photo interpretation work for the Division,

(2) After the landing, one API officer was loanedto the 12th Marines and thereafter one set of each photo

coverage received was forwarded directly to the ArtilleryRegiment as quickly ac possible* It was found that byallowing the artil lery organisation to oonduot and followthrough on their own interpretation of aerial photographsthat the delay incident to Division Intelligence personneldetermining targets and transmitting the information to theartil lery was saved* It le strongly reoommended that twoAPI officers be assigned to artillery regiments for thepurpose Indicated above.

4. &

(a) During the planning phase suitable vertloals,mosaics and obliques should be made available in time forcomplete distribution down to and inoluding platoon leadersprior to embarkation. Photo coverage received prior to andduring the operation were excellent; but an lnoreased quanti

ty sufficient for distribution above le highly desirableprior to the initial landing.

(b) It wae found impossible to pick up enemy positionsin the Jungle from aerial photographs. Except for the defensive positions oh Cape Torokina, at no time were any ofthe subsequent enemy defenelve positions determined fromaerial photographs. Artillery targets beyond the beach headline were determined by noting the gradual lnoreaee in theuee of tralle and oroe sings aoroee the Torokina River. Dueto the Jungle the great majority of close in *lr searchesrequested were neg-tive.

<o) It ie not considered that the taking of aerialphotographs in Jungle areae after landing is of any valueuntil the enemy has been definitely located In strong

defensivepositions.

No aerial photo eoverags was reouestedon this operation until D plue 20 daye due to the fluidityof the situation. -

considered, to the following conditions:

(a) The persistent Instinct of personnsl toretain Items as souvenirs even though they had been thoroughly Instructed to the contrary *>rtor to' the landing.

(b) The drain on personnel required for supply

and evacuation purposes did not leeve, in organisations,sufficient personnel to collect, segregate, and guard captured

(o) Transportation problems ovor poor trailswere so aoutc that, due to the demands of supply and evacua-tion, captured material oould not be moved and thereforevpB abandoned or destroyed In the Jungle.

(2) It Is considered that the only practicablemethod of assuring that captured material, and documentsare not lost, destroyed, or retained as souvenirs is tohave special units, supervised by offlocrs, right on thescene whose primary miselon Is to gather, segregate, protectfrom the clem ants, and safeguard captured material anddoouments until proper disposition 6f same can be made.Regiments do not have suff latent spare personnel to perform

the above tasks and It is believed that special units sentdown from higher echelons to assist organisation tommandera inthe gathering and safeguarding of captured material wouldprove to be of inestimable value. See discussion on special

MARINE DIVISION

1. PLANNING.

Third Marine Division participation in the DIPPER o^era.tion commenced October 4, 19 W with the submission of an embarkationplan for the movement of the Division reinforced by 3d Defense Bat-talion, 2d Marine Raider Regt {Pro -lJional) ,

Ist 155mm Arty Bn, IMACNaval Construction Bn, Detachment CuMAIRUORSOLS, Advance Naval Base

Unit #7, ACORN 13 , Branch #3, 4th Base Depot, Advance Echelon Headquarters IMAC, let Echelon H&S Bn lI£AC and le t Echelon Ist Corps

Signal. Bn. This plan (based on the shipping available together with

certain restrictions on the amount of cargo that could be carried)called for some 13,900 men and 6,£GO tons of cargo in the first

echelon of eight APA's and four A& A!s for the D day landing, followedby five LST echelons five days epart, eaoh carrying approximately3000 troops and 5,500 tons of cargo * The organization of the 3d

Marine Division, reinforced, for this operation ie shown in Annex "A*.

COMMENT: This plan, with the addition of echelons totransport the 3?th Division ana with minor changes to meet the situa-

tion as it developed, was successfully carried out substantially asplanned.

The AKA'e were formed into a separate transport group.Buch a group has an excess of cargo over personnel fo r combat loading

and has no place In a landing against possible enemy opposition. It

is recommended that AXA's to be used on D day be fitted into other

transport groups in aooordanoe with the tactical plan rather thanbeing formed into a separate group.

SBPPLXKt.

The embarkation plan contemplated that the first echelonwould carry three unite of fire fo r troops embarked (except two unite

for heavy AA units), ten days landing rations, ten days B rationsand ttoft days fuel; and that svoosedlng echelons would carry similaramounts for troops embarked plus additional quantities lntonded tobring levels on hand at D plus 90 days to five units of fire and

thirty days of other supplies. Eaoh combat team was also furnisheda thirty day supply of malaria control and medical items.

OQNMEHT: This scheme worked satisfactorily but for futureoperations such items as malaria control and medical supplies shouldbe Intrusted to the combat teams only, in amounts to mee£ immediaterequirements, the bulk of such supplies should be shipped laterafter division dumps have been established* Also replenishment s inequipment and clothing (TBA Oroup 12) should be scheduled fo r ship-ment at intervals beginning about D plus 10 days.

3. SHIPMENT.

The equipment of the division was divided into three categories as indicated below.

Category kx Equipment required to live and to fight fora limited period in a limited space.Equipment necessaryategory B: for the continuation ofcombat and extension of the combat zor.u.

Category C: Equipment for which uo need was contemplated

within the first 30 days, (to be sent forwardon call).

Equipment ism assigned to the several categories axterconsideration of the the terrain of the proposedtheater and the minmmtmjmfiW^wf 03#ecJLpd. These same principles

formation of the battalion landing teams to lar.*were applied to theD day (for example, no tanks or antitank units were attached to

onthese landing teams).

COMMENT: The application of these rules produced a rcin-

forccd'tjattnllon landing team which could be acebmodated on one A?Awith necessary

with a load limit of 500 tone (category A equipmentsupplies), with the remaining category B equipment and units to

satisfactorily bu tfollow in successive ochelons. This plan worked closely spaced.can bo applied only when the several echelons are

4. shore part ies.

Each APA was required to furnish a complete shore party

of oome 550 officers and mSn, of which lj» wore for work inJ-'C

ship, 60 were used as "boat riders" and 200 on the beach "j^tn the

of unloading cargo from boats"; remainlngpersonnel beingsole duty

used for shore party fieadquartors, pioneer work, vehicle fivers,dunro supervisors, men

ommunicators, medical oorsonnol, teach party and

for work at inland dumps. Each AKA was supposed furnish 120

to work in the holds, 50 men to ride the boats and

o 200 on the beach

with the sole duty of unloading cargo from boats. As the AKA'snecessary up thecarried only 350 officers and men, it was to make

difference by drawing men from the APA's (in addition to the regular

with an adjacent; APA, the APAAPA shore party). Each AFA was Joinedshore party headquarters supervising the work on both beaches.

COMMENT: The application of those rules meant about 40#

of the entire landing force was initiallyengaged on shore party

duties. It Is believed that this number is excessive. and that withproper organization a shore party composed of 30% of the landing

APA).force should be sufficient (450 for an average It is alsobelieved that the personnel capacity of the AKA's to be employed on

D day should be lnoreased so that an AKA can unload itself withoutthe need of drawing additional working details from the APA's.

5. FIRST PHASE.

Twelve ships unloaded simultaneously on D day (November Ist)on a front of 8000 yards. Difficult hydrographic conditions causedthe lose of some 86 boats on their initial trip. Difficult terrain

inland (swamps) made the formation of inland dumps impracticable andall cargo was placed on the beach itself, Just above the high watermark. Heavy surf caused the abandonment of the three western beachesafter the personnel had landed, all cargo originally intended for'

those beaches was diverted to other beaches. The loss of large

numbers of boats slowed the unloading; this condition was aggravatedby frequent alerts which caused the ships to cease unloading and put,

to sea. Eight of the twelve ships completed unloading on D day, theremaining four returning on D plus 1 to complete unloading.

COMMENT: Regiments gradually assumed control of their

beaches and consolidated their dumps but it was not until November 12

that division was able to assume control of the supply of rations,

ammunition and fuel. During this period organl ra t ions and unite

obtained tholr supplies from the nearest shore party dump. Tc pcrrcitthe regiments to perform this function, many units remained attacn^u.to the rogimonts that would normally have reverted to organic controlearlier. For example, the dates on which certain units reverted toorganic control is indicated below:

The long delay Indicated by the above table vac ca'.uod '\\the lack of roads Inland which made it necessary (in ao fa r ac eupyly

and evacuation was concerned) to leave the problem in the hands ofthe regimental commanders until the situation clarified and the roqulrod supply routes could bo devoloped.

6, ROADS.

Initiallythere were- no roads. (The one native traMleading inland on the right flunk broke dorvas soon as it wan sub-jected to heavy traffic.) The beach itself was used, as a rosxi forall lateral traffic and amphibian traotors wero used fo r the nov«ment of supplies and fo r the n\ acuatAon of wounded; track layli'f^trailers pulLed by traotors wh*c aXco used where practicable. C&lffhteen track laying trailers wi5h rt -9 traotors had been obtained .e^eclally for this operation). Tho front linos gradually advanced in land across the swamps until dry ground was reached. A divisioninland dump was then established vDump No. 2, three miles by roadinland from tho beach). Until a road was built supplies were trans

ported to ,thiB dumo by amphibian tractors; joeps and trailers werealso porto-ed forward by amphibian tractor for local distributionfrom this forward dump. This procua6 was repeated at- a.later etap:e

of the operation to raoet a similar condition, i.e. the front lines

advanced again across swanros beyond the existing road not. The tablestages.below show 8 the various

Thereafter: Normal supply, by truck to regimental orbattalion dumps, thenoe forward by Jeep,•track laying trailor or hand carry.

COMMENT: On November" 13, the date on vhloh the first major

movement of supplies by amphibian traotor•oommenoed, there were 64

amphibian traotors available. (X INovember 86, the date the roadopened and amphibian tractors were relieved by trucks, there wereonly 28 amphibian traotors still in operation. By December 9th, 48amphibian traotor e had been repaired and made serviceable, but by

Deoember 23rd only 12 remained In running condition. It la obviousthat amphibian traotore are special instruments fo r special operations and cannot bo depended upon for hard servioe over extended

this fact, salvage operations should be started early and plans shouldprovide for the shipment forward, commencing about D plus 10 rays,of replenishments in all typos of equipment. This equipment shouldbe earmarked for this purpose and shipping space provided for it

in the original embarkation plan. As a rough figure the TBA 90 dayreplenishment allowance should be provided for c ach 30 days of activeoperations.
