A reconnaissance was made of Elcho Island, and the vessel  
taken through Cadell Straits, where a further reconnaissance on foot
was carried out on the Napier Peninsula region west of Buckingham
Bay.  On March 4th the AROETTA sailed to an anchorage behind Hardy
Island on the western side of Arnhem Bay.  I was anxious to
establish contact with a native of this area, Bindjarpuma, also
known as "Slippery" who was at this time the most powerful and
aggressive man in this part of Arnhem Land, and who had for some
years led the life of a predatory border chief, making periodical
raids on his neighbours and then returning to the hills.  At the
same time, while searching for the man and his group, it was planned
to employ the interval in unloading the heavy cargo from the ship,
and to careen her in a sheltered sandy corner under Hardy Island,
to clean the copper.  This work was carried out on March 5th and
6th, and the vessel refloated and loaded again.

Meanwhile, patrols were carried out in the neighbouring
country and the native Bindjarpuma and his group located. A meeting
was held with this man and his fighting band, and Bindjarpuma and
most of the able bodied fighting young men of the group were enlisted.
By the evening of the 7th of March, 36 picked men, all good travellers
and hunters, some of them renowned ad fighting men in single combat
had been collected. Only a nucleus was required to travel on the 
ship, and as I had decided to limit the enlistment in the meantime
as I wished to select a number from my old friends at Caledon Bay
no further natives were enlisted on the north coast. An account 
of the enlistment and organisation of the detachment being formed is
set out in a section which follows.

The whole of the detachment was taken aboard the AROETTA
on the afternoon of March 7th, and landed again that night on the 
south-east corner of the Bay. On the following morning I joined
these men and set out with them on a patrol overland to Caledon Bay.
After landing here the AROETTA in charge of Sergeant (Lieutenant) 
Palmer, sailed for Caledon Bay where the vessel arrived the following 
day.

The distance overland between Arnhem Bay and Caledon Bay
is a little more than 40 miles, but the country is rough, with many
rugged hills outcropping with rock, and some swamps and rivers.
Most of the native detachment completed the journey by the following
night, but some were unable to maintain the pace and came a day later.

Again, no natives were found at Caledon Bay, and it was
apparent that the group which belonged to the area must be farther
to the south.

On March 12th the ship left Caledon Bay for Trial Bay, an
unchartered bay a little to the south. The Caledon Bay group was
located in the bush a little to the south west, and moved down to the 
sand beach close to the ship.  Friendly relations which I had 
established years before with the fine, bold and warlike people 
were renewed, and we were inundated with offers from the men to join 
the detachment.  As a nucleus only was required at this stage the
number had to be limited. The men selected were especially fine
specimens, all people who had grown up in an area where tribal feuds
were still carried on, and where guerilla fighting still plays an 
important part in their lives.  Many of these men were renowned 
warriors with almost legendary reputations for the prowess as spear 
fighters, and some them had already killed Japanese (1).
__________________________________________________________
(1) NOTE:  In 1932-33 the natives of the Caledon - Blue Mud Bay
areas - besides killing most of the crews of two Japanese manned
luggers, to which reference has already been made, also killed two
white men, Traynor and Fagan at Woodah Island, and at the same place
in the same year, ambushed a party of the N.T. Police and killed one
of their number (Constable McColl).  All these parties were armed
with firearms and were expecting attack, but the natives, using only
their own spears, suffered no casualties.
 

 

26.

It was possible to make only brief contacts with all
these natives, for time was now short for the completion of the
programme laid down by March 21st.  Wherever possible I went
inland on foot, travelling and living with the natives, and
re-establishing contacts. The allegiance of the natives of
this area was never in doubt however, for the Japanese are
almost hereditary enemies, and they needed little encouragement
to begin preparing for the resumption of possible landing parties,
by forging their own "shovel" spears from odds and ends of metal.
Anything or iron, ranging from heavy oil drums and iron bars to
galvanised water pipes, and horse shoes are beaten out cold, and
skilfully forged into SPEAR HEADS.

On March 13th, a signal was received from Headquarters with
notification of Sgt Palmer's commission.

On March 14th, we left Trial Bay for Groote Eylandt, anchoring 
off the Advanced Operational Base at the S.W. corner of the Island.
The following day was spent in watering the vessel, and Lieut.
Palmer was sent overland by M.T. from the R.A.A.F.  A.O.B. to take 
delivery of safe hand mail from the Flying Boat Base. While the
AROETTA lay at anchor off the A.O.B. on March 16th, two multi-engined 
aircraft, apparently Japanese long range reconnaissance
flying boats, flew low over the A.O.B. and passed, one on each
side of the Aroetta, at apparently 3,000 feet, without dropping
a bomb or making any demonstration. It is assumed that these
aircraft were engaged in photographic reconnaissance, particularly 
as this incident almost immediately preceded the raid on Katherine.
We were handicapped in challenging the aircraft to ascertain
definitely their identity, as the W.T. operator was receiving a
signal of "immediate" priority while the aircraft passed over. In
view of the priority of this message, and its possible relation 
to the aircraft then overhead, I deemed it advisable first to
receive the incoming message and to decode it, rather than break
off with the risk of losing contact to permit the operator to
see the Aldis Signalling Lamp.

A message was sent recalling Lieutenant Palmer, so that the
ship could be moved from the vicinity without delay, as she was at
that time carrying the whole of the equipment of the Unit, no
suitable opportunity having yet occurred for the dispersal.

On March 17th we arrived off the mouth of the Roper River,
and the following day proceeded upstream. Two boats were lowered 
when the ship arrived off the estuary, and most of the native detachment 
was then landed to avoid exposing all these men on deck in
view of the presence of enemy A/C.   Just when the two boats, fully 
loaded, were leaving the ship, a heavy bomber approached, but it
proved to be a United States machine.

The mouth and approaches to the Roper River have changed considerably
during the recent years, and there is now a bar with little
more than one fathom of water, nearly five miles out to sea, and
a vessel, missing the narrow and unmarked passage, would probably
be driven on to a bank, with the risk of breaking up, if a heavy 
squall arose from the weather quarter before she was refloated.

Progress upstream was slow, on account of the depth of the
Aroetta. Fully loaded, the vessel was now drawing 8 - 9 feet,
and owing to the "drag" over shallow areas, she had to wait for 
the tide at several places. Meanwhile, the native detachment was
put ashore and carried out a thorough reconnaissance along the 
banks of the country fringing the river in preparation for
possible future operations against an enemy using the river to
approach the L of C. On March 19th, the Aroetta arrived at the 
Mission Station (Roper River Anglican Mission). The natives, who 
had not tasted fresh meat for some time and who had been working
hard on foot patrols, had been promised a bullock on arrival at 
the Roper River, and a steer was now obtained from the Mission,
slaughtered, and handed over intact to the detachment.

 

 

27. 

Advantage was taken of this period in the Roper River to
drill the crew again regularly and to take in hand the newly
recruited detachment, which now numbered fifty fighting men and
to get them into some shape.  A parade was held each morning
in order to instil the elements of discipline into these nomadic
hunting people.  Some account of the training of the native
detachment will be given in section 8 which deals with the organisation 
of the native force.

The M.V. "Larrpan", which is normally stationed at Milingimbi
in the Crocodile Islands, and is employed in the transport of stores
to the Methodist Missions on the North Coast, had arrived in the
Roper River with evacuees from the Methodist Mission Stations.
These people, the white women, have castes, and Fijian women from
the Missions of Crocker, Goulburn and Milingimbi Islands, as well
as from Yirrkala, were conveyed from Roper River to the railway
line by military transport which had come down to meet them.

From March 19 to March 23rd, the Aroetta remained at the 
Roper River Mission.  In addition to the drilling of the crew and
the native unit, a considerable amount of general reconnaissance was
carried out on both banks of the River. An appreciation of the 
situation in the Roper River at this time revealed the fact that 
it was wide open to any enemy party which night come upstream. No
watching organisation of any kind existed and there was not even 
a native camp for the first sixty or seventy miles from the mouth 
to give warning of an enemy landing or approach. 

Arrangements were made with the Missionary in charge (Mr. Port)
in the meantime, pending the setting up of a more permanent O.P.
to send a party down to watch the mouth of the river and to build 
a pyre on a high hill as a warning. Some weeks later, a permanent 
O.P. equipped with wireless, was established at Gunara Bluff
commanding a view of the mouth of the river and its approaches, in
order to cover this very vulnerable area.

On March 23rd the Aroetta proceeded upstream, to the Four 
Mile Landing, which is the limit of navigation for a vessel deeper
than a dinghy on the Roper River. This landing is situated on 

the south bank of the River four miles from Leichardt Bar, at which
the Roper Bar Police Depot is situated. The landing above the 
junction of the Hodgson River with the Roper and a few hundred yards
below the junction of the Wilton. Here we awaited the arrival of
M.T. which was to transport the native detachment to Katherine as 
had been laid down in the Operation Instruction (No 1).

On March 27th, two 3-ton M.T. from No. 4 Independent Company 
which had recently replaced No. 8 Independent Coy. at Katherine,
arrived and on the 29th the detachment of 50 natives, together with
arms and ammunition and equipment left for Katherine with O.C.
Reconnaissance Party. On the same day the Aroetta, under Lieutenant
Palmer, sailed down the river en route for Darwin, under orders from 
7 M.D. Headquarters.

On night of March 30th, a camp was made with the native detachment 
on the Roper River at the Elsey Station, and contact again
established with the Manager Mr. Harold Giles, whom I had known 
for some years. Mr. Giles was born in the Northern Territory and 
has had life long experience of the area. He is an expert bushman
and knows the Territory terrain as few white men know it.  Arrangements 
were made to enlist the co-operation of Mr. Giles in the event 
of later operations in this area.

Furthermore, Elsey Station was so situated as to form a good
depot for reserve of ammunition and equipment for any small mobile 
force working in the Roper River, which might be unable to transport
bulk stores father down the river in times of heavy rains and
floods.

 

 

28.

On March 31st the party arrived in Katherine. In order
to avoid the possibility of disorganising the natives, and to
maintain discipline, which had been very good to date, it was
considered advisable to establish a separate camp some distance
from the regular camp area. A site was selected some two miles
down stream on the banks of the Katherine River, which by arrangement
with the Camp Commandant, was placed out of bounds to all
the white troops in the area. No difficulty was experienced
in keeping the natives within their own zone, but as their
arrival has created some interest among the troops it was very
difficult to enforce the prohibition. An undesirable feature
was the fact that whereas the natives had been encouraged to
carry, and maintain always, a certain number of spears, both
for hunting and fighting, for reasons which will be apparent
later, were to be their chief weapon in the event of guerilla
operations against and enemy landing force, the white troops 
persistently endeavoured to induce the natives to trade these.
This not only left the men without proper arms, but once the
edict had been issued, had to be enforced or discipline would
have broken down.

A conference was held with Major Walker, O.C. No. 4
Independent Company, and Lieutenant Burton of that Company who was
about to leave with a section for the Roper River, in order to 
inform them fully of the situation on the Roper area and to pass 
to No.4  A.I.C. the results of the recent reconnaissance there.

As information was to be obtained at Katherine as to the
covenant which we had just raised and which I had been instructed
to bring to Katherine, and intended role of the native detachment,
and as there had been changes in Command, I considered it advisable
to proceed to Headquarters for a general discussion and for new 
orders.  A request was therefore made for authority to leave the
detachment at Katherine, and to proceed to Darwin by air. I was
reluctant to be away from the natives for any length of time, as
I was alone with them having no N.O.C. to bring with me in view of
the smallness of the Unit and the danger of undermanning the ship.
I had promised these men when they were enlisted that I would never
desert them whatever befell, and did not with to leave them now
in a strange military camp, hundreds of miles from their own
territory.  Approval was granted to my request and on April 5th,
I proceeded to Darwin by Lockheed leaving Raiwalla in charge of
the camp and detachment at Katherine.

At Advanced Headquarters I reported to Operations section
and a conference was held with the G.S.O.II (Major now Lieut Col
G.H. Finn) and subsequently with the G.O.C. (Major General Herring)
who then issued a new Operations Order (7 M.D. Operation Instruction
No.13).  This simplified and also greatly extended the scope of
the previous order (7 W.D. Op Instruction No.1) under which we 
had been working since he had left Darwin. This new Operation
Instruction laid down that the Forces consisting of the crew of the
Aroetta and the native unit already formed, together with any other
native personnel who might be added to it, was to be known as the
Special Reconnaissance Unit, and so definitely established this
Unit as an independent command to operate on the distant flanks of
the area, with a reconnaissance and fighting role. One of the 
functions of the Special Reconnaissance Unit was to pave the way
for the Independent Companies and other flank forces, and to
co-operate with these forces.

On the morning of April 7th I returned to Katherine, as I was 
anxious to see the natives as soon as possible.  This visit to
Force Headquarters had occupied only two days, but I left with a 
clear understanding of our role, and full appreciation of just what
our tasks and responsibilities were.
 

 

29.

We knew that we had the entire coastline from Cape Don

to the McArthur River, as well as Groote Eylandt and other

islands off the coast, to watch, and to prepare against possible

enemy landings - a coast line of more than 1000 miles. We knew

also, for we had been told clearly, that we could expect no help.

I can still recall now the feeling of pride that we all drew from

this order and which told us to remain on the flanks and "to

harass enemy landings and progress in the event of landings on

the east coast", and the determination that we felt that whatever

befell we would remain at our station. We did not overlook the 

fact that we were only four while men with a 65 ton ship. But

we knew that if the enemy should land on this coast we were 

entrusted with a responsibility so great, and an opportunity to 

serve that might never again be given to so small a body of men.

It gave is fresh encouragement in the task of raising the native

unit and training these nomadic people.  Hitherto we had heard

nothing but disparagement of this native force.  We know now that

our faith in the native forces that we had been sent out to

raise and which had been so laboriously built up and trained, was

shared by the G.O.C. and his Staff, and we returned with fresh

heart to a task that had proved always exacting and difficult, and

often disappointing.

 

I am proud to be able to tell now of the work carried out

in the six months which followed by the handful of men, white

and native, under my command, and to record the story of relentless

unremitting hard work, unselfish service and initiative, displayed 

by these men working with one objective. In all that time not

one of the men obtained, or asked for, any leave to relief, there

was no grumbling or discontent, but everyman in this unit carried

out willingly and cheerfully what should have been the work of

two men. Guards were maintained throughout every night;  the men

did armament as well as deck and other duties, they handled all

the cargo, they fuelled the ship, often swimming out with the

heavy drums of fuel. They watered the vessel, filling the tanks

of the vessel with drums from wells that they dug ashore; they

cut firewood, they careened the ship and cleaned the copper, and

at the same time, they were drilled, trained in the use of small 

arms and turned gradually into soldiers as well as sailors.

 

At one period, the Unit was divided into three detachments,

operating hundreds of miles apart - one Sergeant ashore in charge

of an O.P.I. Lieutenant Palmer and the W.T. Operator on the Aroetta

while I was away on reconnaissance with M.T., operating between

the Roper River and Borroloola on the McArthur.

 

Most of us expected that following the heavy raid on Darwin

and the raid on Katherine, when reconnaissance aircraft were

frequently sighted, that the enemy would make a landing somewhere

on the east coast at Milingimbi, Groote Eylandt or the Roper River,

and we set out at once to prepare for this.

 

It was obvious that any plan, to be of real use must be

carefully prepared and rehearsed and skilfully executed. My

first objective therefore was to establish a good and effective

O.F. equipped with W.T. commanding a view of the approaches to the 

Roper River which at this time was wide open, since early warning

of the approach of an enemy would be vital to Headquarters. The

fact was not overlooked that, important as might be the guerilla

operations, we might be able to carry on the most vital role was the 

rapid passing of information of an enemy movement to H.Q.

 

The next most important point was to disperse ammunition

and equipment that if the ship should be lost we would still possess

arms and ammunition to carry on. Finally, it was necessary to

establish and maintain an O.P. apart from that to be set up at

the Roper in area where the following conditions would be found:

 

 

30.

  1.  The O.P. must be situated in sufficiently close proximity
    to the most vulnerable points - Milingimbi, Groote Eylandt,
    and the Roper River - to enable raids to be carried out at 
    night with natives to destroy enemy aircraft on the ground
    and to sabotage fuel dumps and equipment.
  2.  It must be situated in an area where the natives were well
    disposed and absolutely to be relied on it the event of an
    enemy landing, and where in the meantime regular contacts
    could be maintained, with the natives to prepare them for the
    role they were to play and to enable them to be mustered
    at the first warning of enemy approach.
  3.  Though located close to a likely point of enemy attack,
    the O.P. should, if possible, be situated at a point not
    likely itself to be attractive to the enemy, and therefore
    one at which they were unlikely to land.

Before leaving Darwin on return to the east coast, where the 

Aroetta was the meet us at the Four Mile Landing near Roper River,

arrangements were made to replenish all stores on the Aroetta to

enable the vessel to remain for six months without further supplies

except of fuel, and plans had been made to lay down a fuel depot 

at Groote Eylandt so that the ship need not leave her station at

a critical time to refuel.

 

In view of the plan to attack enemy aircraft on the ground,

certain special stores had to be obtained. The vessel was already

well equipped with demolition materials, but materials for the

making of Molotov cocktails were inadequate. For this purpose a

drum of bitumen was obtained in Darwin and a raid then conducted

on all the hotels which remained after the first air raid to secure

as many clear glass bottles as possible since these are the most

suitable for this work. From these forays, conducted independently

the crew returned each with a sack of empty bottles on his back.

Every man put his heart into this acquisition of equipment for the 

task ahead with a zeal that would not be denied.

 

(II) Return to Roper River: Establishment of Depots and O.P.

On return to Katherine, arrangements were made to transport

the native detachment of 50 men back to the Roper River. A convoy

of two 3-ton trucks was made available and in addition a 30-cwt

vehicle was taken on charge by the Special Reconnaissance Unit

for land transport in the Roper-McArthur River areas where

necessary.

 

It was considered imperative that the O.P. which I intended

to establish at the mouth of the Roper River should be equipped

with wireless. It has not been possible to obtain the necessary

equipment at Headquarters at this time, as there was a heavy call

for W.T. transmitters and equipment and already been issued.

A W.T. set was therefore impressed from Roper Valley Station for

this O.P.

 

On route from Katherine to the Leichardt Bar, Roper River,

a depot was laid down at Elsie Station, containing a reserve of

S.A. ammunition and rations. A second depot was established at

the Roper Bar Police Depot, containing further reserves of ammunition

and in this depot which was considered reasonably safe, certain

weapons, including a Bren, LMG, and number of [[?]] rifles and

ammunition, were laid down. As Roper Bar was at the end of the

Road up to the L of C, the motor vehicle and fuel supplies were also 

laid down at this point. In establishing a reserve store of arms

and leaving the WT here, consideration was given to the fact that

headquarters of a Platoon from No.4 Independent Company, was being 

set up at Roper Bar Police Depot. Subsequently, a small cache 

of two cases of S.A.A. ball ammunition was secreted in the rocks of

a hill overlooking the river close to the Four Mile Landing, which

could be reached by night in extreme emergency even if the area

should be strongly held by an enemy fire.

 

 

 

On April 15th the Aroetta arrived on return from Darwin,

and on the following day the whole of the native detachment was

taken aboard the vessel and proceeded down stream to the Roper 

River Mission. Natives were landed on the north bank, under 

Pte Raiwalla to make a foot reconnaissance of the north bank

of the stream between the Roper River Mission and of the mouth

of the river.

 

While proceeding downstream on April 19th an obstacle,

believed to have been a submerged, waterlogged piece of timber

or log was picked up by the propeller and passed through the

propeller aperture, damaging two of the blades and throwing the

propeller out of balance. Copy of the report on this incident is

included in Appendix 4. To avoid excessive vibration the engine

had now to be run at low revolutions, thereby greatly reducing her 

speed and power. On April 22nd the vessel was anchored at No. 1

Survey Camp close to the mouth of the river and intensive reconnaissance
was carried to:

 

(1)  determine the accessibility of the area for enemy AFVs

 

(2)  to locate the most suitable site for a permanent O.P., and

 

(3)  to endeavour to find water, which in this season, was 

       unusually scarce.

 

A local patrol was carried out on foot by Lieutenant

Palmer, with a detail of natives, to the south of the mouth of

the river. A copy of Lieutenant Palmer's report included in 

Appendix 4.

 

As no high ground exists in this vicinity and as no water 

could be found even in native wells at this time, the vessel

proceeded upstream to Gulnare Bluff (Mt Moore) where a further

reconnaissance was made to determine the suitability of this site

for an O.P., for I was anxious to select a site and set up this

post for observation without loss of time.

 

The fact that Gulnare Bluff (Mt Moore) was situated only

six miles from the mouth of the river, and that it commanded a 

view over the estuary of the river and also covered the mouth and

approaches, made it eminently suitable as a site for an O.P. But 

no water was found at this time, other than surface water. It was 

decided, however, that the O.P. must be established and a search 

for water conducted while this work was in progress.

 

(iii) Reconnaissance on Foot Northward to Ross River

 

Instructions had meanwhile been received from Headquarters

for a reconnaissance to be carried out for a distance of 40 miles

to the north of the Roper River Mouth to search for possible enemy 

fuel depots and landing areas.

 

I decided to carry out this patrol on foot while the O.P.

was being prepared. A party was selected from the native detachment 

and leaving Lieutenant Palmer in charge of the ship, I proceeded north

of the Ross River. The area was extremely arid and on the forty

mile patrol to the Ross River only two wells were found. These had

to be cleaned out and deepened and even then provided very little

water. On the afternoon of the second day we arrived at the

estuary of the Ross River after a long hard stage - only to find

that the only native well was dry, and after we had therefore to

retrace our steps at once to the well where we had last obtained 

water. Copy of the report made by signal on this patrol is included 

in Appendix 4, with other reports covering the activities of the

Unit.

 

32.

Work on the O.P. had meanwhile, progressed well and in

order to camouflage the site to the best effect, the camp was 

partially excavated in the ground among the rocks. It was then 

roofed with galvanised iron obtained from an abandoned camp near

the mouth of the river, and this was then camouflaged with boughs

so that it was almost impossible to detect from the air. Some 

difficulty was experienced first in inducting the natives to 

approach the post in such a way that tracks would not be worn 

leading direct from the river to the site.

 

As the search for water, in the area had proved fruitless

this had to be supplied in the meantime, from the ship, until

tanks could be obtained to hold a supply adequate for the needs

of the O.P.

 

By 28th April the work was completed, the W.T. set 

installed by Sergeant Harvey, W.T. Operator on the Aroetta and

satisfactory tests had been carried out. An "Iron Horse"

charging motor which had been impressed for the purpose, was

provided, for the charging of batteries. Sergeant Elkington,

who was the only one of the white personnel who could be detached

was placed in charge of the O.P. with a detachment of twelve

picked natives from the detachment of 50, headed by their own 

section leader. Bindjarpuma or "Slippers". (See Section from 

Organisation of native unit). Sergeant Elkington was provided

with an Operation Order No 3 (See Appendix II) covering the work

and maintenance of this post. We remained in charge for two

months (until July 5th) when the post was handed over to No. 4

Independent Company, and he was relieved.

 

On May 1st the Aroetta again proceeded up stream to carry

water for the O.P.  Two 400 gallon heavy galvanised tanks were

secured from Roper Bar, and these were subsequently installed at

Gulnare Bluff. Both the tanks had been filled with water up

stream, but the additional weight had increased the draught of the

vessel sufficiently to prevent the ship from crossing some of the

sand bars except on a very full tide, and one of the tanks

eventually slipped overboard. The tank was retrieved, but only

four hundred gallons of water remained and the second tank had to

be filled laboriously with surface water scooped from the shallow

pools that still remained on the surrounding plains.

 

As much difficultly was being experienced in securing a

propeller of the same pitch and diameter as the one now on the ship

which had been damaged, I at length obtained authority to send

Lieutenant Palmer by Flying Boat from Groote Eylandt to Brisbane

to assure that the replacement would be of the right diameter and

pitch and tapered to fit the shaft. On May 23rd the Aroetta

arrived at the Flying Boat Base and anchored in Little Lagoon.

While awaiting the arrival of the Flying Boat on which Lieutenant 

Palmer was to proceed to Brisbane, we put the stern of the Aroetta

up for examination of the propeller and to obtain the correct specifica-

tions for the replacement. Now that I was assured of obtaining

another propeller I decided to take the risk of beating out the

damaged blades of the propeller in the hope that, pending replace-

ment, this would increase its efficiency at least a little.

Working in four feet of water, we were able to bend the blades out

with heavy hammers and to remove the rough edges with files.

 

On May 26th Lieutenant Palmer left by Flying Boat, and I

employed the period of his absence in patrols of Bennet Bay, Blue 

Mud Bay and the Caledon Bay areas, in order to maintain the

closest possible contact with these natives.

 

The Aroetta left Groote Eylandt for Blue Mud Bay, on May

29th, anchoring in Bennet Bay, near Cape Barrow. The ship was

now much under manned, as I had with me only the W.T. Operator

in addition to the natives.   Sergeant Elkington, who had served

as engineer, was at Gulnare Bluff O.P. and the native who had 

acted as assistant, Pte E. Richardson, had been sent to Katherine

Hospital and later invalided out of the Unit.

 

 

33.

During the ensuing week the Aroetta worked along the

shoreline of Blue Mud Bay, sailing also at Woodah and Round Hill

Islands, and at various points of the mainland.

 

This is a dangerous shoreline for vessels drawing much

water; it is shallow and uncharted with many banks and reefs,

the more dangerous because the water is always dirty and discoloured.

In the S.E. season the sea rolls straight into the wide, open,

shallow bay. Throughout almost the whole of the period in which

the Aroetta was cruising in this area the engine had to be run

at greatly reduced speed and the lead line used constantly to

feel the way.

 

At each anchorage, detachments of natives were sent

ashore to reconnoitre and to examine the area for signs of recent 

occupation by strangers or by native hunting parties with whom

it was desired to establish contact. A report had been received

from HQ that an RAAF GANNET Aircraft was reported to be missing 

over Arnhem Land.   Sgt. Elkington was instructed by W.T. to 

send out patrols in his territory, and an extended search was

carried out by natives from the Aroetta at each anchorage without

result. On June 2nd a detachment in charge of Raiwalla was put

ashore west of Woodah Island and instructed to carry out a patrol

north of Blue Mud Bay to Trial Bay., and to meet with the ship

there. On June 4th I took the Aroetta out of Blue Mud Bay and

sailed north along the cast, anchoring in Trial Bay, where

Raiwalla arrived with his detachment on the following night, after

a severe journey in very rough country.

 

Many natives were living here and it was at this time

the chief camp of the people whose territories extended over

a long stretch of coastline. Contact was made with Wongo, headman 

of the Caledon Bay people at Trial Bay. Except for reports of 

aircraft sighted, these natives had little to report, and no signs

of strange ships or of Japanese activities had occurred in our 

absence.

 

A number of natives from the detachment had been

recruited in this area, who had tired of the routine work, and

gone A.W.L. and these men arrived back in their home camp while

the Aroetta was anchored in Trial Bay. They readily rejoined the

vessel however, and all served for a further period on an extended

reconnaissance on the Roper and McArthur Rivers. A fuller account 

of the work carried out by this force is set out in section B.

 

I remained in Trial Bay with these natives for more than

a week, in preference to extending the patrol north and west over

a greater length of coastline, working hard with these people,

from amongst whom we had already recruited many men. The value

of an O.P. in close proximity to Groote Eylandt and the approach

to the Roper River, was stressed earlier in this report, and I had 

already planned to establish this base a little later, among the

Caledon Bay people, either at Trial Bay or in Caledon Bay itself.

For this reason close contact with them now was essential. These

people offered just what was required; they were so notoriously

hostile to the Japanese fishermen in recent years, that it was

unlikely that the Japanese would select their territory as a 

landing point for small parties, even if it had otherwise any

advantage. They were warlike, and numerically strong, and as I

myself was on very friendly terms with them and spoke their language

their territory would afford an excellent base. But being high

spirited and independent, they were not easy to handle, and

discipline was hard to them, as it does to most natives.

 

On June 13th, I took aboard the whole of the detachment

again and sailed south to Groote Eylandt to the A.O.R.  The ship

proceeded then on to Port Langdon to pick up Lieutenant Palmer who

returned on June 21st. Lieutenant Palmer brought a new propeller 

and shaft which were flown up with him from Brisbane. The straightening

out of the blades which had been attempted after some

hesitation, and which was regarded as an emergency measure only,

 

 

34.

had proved so satisfactory that it was now possible to run the

engine at the full normal speed of 1000 revolutions without

excessive vibration, and as it was now considered advisable to

slip the vessel before the end of the year, the damaged

propeller was not removed in the meantime, instead the replacement

was had in reserve, to that if possible the work could be carried

out on the slip by experts.

 

On June 29th the Aroetta anchored off the O.P. at Gulnare 

Bluff. Sgt Elkington had nothing of importance to report. Both

be, and all the members of the detachment, were in good health, and

spirits, but they were suffering severely with the mosquitos which

were present in great numbers, and came out in hordes at night, 

and during the day were much troubled by flies. Conditions at

the O.P. were severe and extremely monotonous. The surrounding

country was flat and uninteresting, consisting merely of miles

of salt pans and plains intercepted with mangroves. Nevertheless

Sgt. Elkington and the detachment of natives had carried on their 

work at this O.P. - maintaining a constant look out, keeping regular

schedule with the ship each day, and carrying out patrols in the

surrounding country. The N.C.O. and his detachment had carried

on their difficult and lonely undertaking excellently throughout.

 

In the meantime arrangements had been made to hand over

this O.P. to No 4 Independent Company, which was now in a position to

supply the necessary personnel to take over the whole of the Roper 

River area and so to free the Aroetta for patrol work further out

on the flanks.

 

It had now been arranged that I was again the visit Force

Headquarters to report. As this Unit was responsible for

reconnaissance of the area as far south as Pellow Group and the

McArthur River, and the territory generally north of Nutwood 

Downs, it was considered most economical to send the Aroetta after

landing at Roper Bay to carry out reconnaissance of Maria Island, 

the Pellow Group, and the McArthur River. It was planned that

I should then proceed overland on the return from Darwin, to make

an extended reconnaissance by land, meeting the Aroetta at Borroloola

on the McArthur River.

 

On June 29th, the ship was again taken upstream to the 4

mile Landing near Roper Bar, the whole of the cargo was removed to

enable a general check to be made, and to clean out the holds.

Meanwhile the depot which had been maintained at Roper Bar Police

Depot was withdrawn, including arms and ammunition, and loaded on

the vessel. While this was in progress the crew was sent ashore

regularly to drill and for bayonet exercises, a routine which had

been suspended while the ship was at sea on patrol.

 

Arrangements were made with Captain Thompson of No. 4

Independent Company to proceed down the river on the Aroetta and

to take over the O.P.  This post was handed over on July 5th, when 

Sergeant Elkington, together with the detachment of 18 natives,

rejoined the ship and resumed duty as engineer. Lieutenant Palmer

then proceeded with the Aroetta via Maria Island to the Sir Edward

Pellew Group and the McArthur River, carrying out the work laid down

in Operation Order No. 4 (See Appendix II)

 

Meanwhile on July 4th I left Roper Bar by M.T. with a

detachment of six natives, one Solomon Island member of the crew,

and five other natives, for Force Headquarters.

 

At Force Headquarters a discussion was held on the future

role & Identity of the Special Reconnaissance Unit, and as a result 

an application was made at this time for a definite establishment for

the Unit, and for a separate colour patch. It was felt that such

establishment and definite identity would assist in holding together

this force and that it would further serve to foster a pride in the 

Unit and build up a solidarity which is essential to the success of

any organisation of men however small.
