WW2 HQ Ships and HQ Assault ships shared the task of
implementing the detailed plans for large scale amphibious landings onto
unimproved beaches in enemy occupied territory. They
achieved this through a complex communications network
monitorthe progress of the
battle against the plan and to direct the coordinated operations
of the Army, Navy and Air Forcein the light of
fast moving events. They
were floating, effectively, Command and Control Centres with the capacity to communicate with aircraft,
ships, shore establishments and units operating in the battlegrounds.
Philip Zieglar wrote in
Mountbatten's official biography, "One of the more
valuable gifts, which Mountbatten endowed on Combined Operations, was the HQ Ship.
It may seem obvious today that a massive and complex amphibious operation needs
to be controlled from a vessel, which remains offshore after the landing, which
is not liable to be removed to take part in some naval operation and into which
all the communications from land, sea and air are channelled."
Mountbatten certainly claimed to have discussed the idea with his, then
Assistant, Fleet Wireless Operator, Michael Hodges in the 1930s but it was not
until the ill fated attack on Dakar in 1940, that the need for an independent
floating command, control and communications centre was fully understood.
General Irwin wrote, "Seldom have I felt so impotent, as during this expedition,
when I was separated from my forces and tied to any naval operations which
might become necessary. The Commander of any such enterprise must retain his
independence from the fleet."
In any event, the idea of HQ ships was taken up by Combined Operations HQ (COHQ).
Mountbatten cajoled the Ministry of War Transport into
supplying a vessel to develop the concept. HMS Bulolo,
a former Australian Passenger ship of 6,400 tons, was stripped of non essential
equipment and refitted with communications equipment and control room
facilities. The work was completed in the summer of 1942, by which time the
conversion of a second HQ ship, HMS Largs, was underway.
- an account by Edward (Ted) Pierce, who served on
the Royal Navy in November 1941 and was drafted to HMS Glendower, a shore
based training establishment at Butlins Holiday
Camp, Pwllheli, where I learned basic seamanship. A few weeks later, I attended HMS Valkyrie
in Douglas, Isle of Man for training in naval Radio Direction
Finding (RDF), an early form of Radar.
[A typical layout of the Operations Flat on an HQ ship where signals were
interpreted and orders issued. Note the proximity of Army, Navy and RAF staff -
a perfect example of a Combined Operation. Many of the sections in the plan are
fully described on the Fighter Direction Tender web page.]
After six weeks training, I had become
an Able Seaman, RDF. I was drafted to HMS Bulolo in the Royal Albert
Dock, London, where it was undergoing conversion from an armed merchant cruiser to the first ever Combined Operations HQ ship.
Admiral Mountbatten, who had been appointed to
head up the Combined Operations Command in October 1941, had been instrumental
in championing the role of HQ ships in amphibious warfare and I was to take part
in the early use of seaborne Radar.
By June 1942, Bulolo was engaged in sea trials off the coast of Scotland,
during which Mountbatten came aboard to learn of progress first hand. Before long, signals
personnel from Army and RAF units joined the ship’s company together with additional Naval officers and
ratings. The RDF ratings were responsible to a Canadian
'green-stripe' sub-lieutenant and a leading seaman RDF by the name of Tom
O’Carroll. He had served on a Flower Class corvette, where he had earned a DSM
for detecting a U-Boat, which lead to its sinking.
Our first operation as an HQ ship was the
invasion of North Africa, codenamed Operation
Torch. The convoy comprising 300 ships departed various UK ports around the
end of October 1942,
sailing under the flag of Admiral Sir Harold Burrough in Bulolo and destined for
Oran and Algiers. Also on board were high ranking officers from all three
services, British and American, including Generals Ryder and Mark Clark.
The voyage was uneventful but, after passing undetected through the
Straits of Gibraltar, we came under attack from enemy aircraft.
Nevertheless, successful landings were made and in due time Bulolo proceeded with imperial dignity into Algiers harbour.
Unfortunately, as Commander Anthony Kimmins reported in his BBC broadcast that
night, all did not go well, "while approaching the harbour that morning, Bulolo
had been heavily dive-bombed by Hun aircraft. A near miss had rendered the
telegraph indicators, linking the bridge to the engine room, out of action. As there had been no occasion
to use the telegraph between then and coming into harbour, there was no reason to
suspect they had been damaged.
Now, as the captain rang down ‘Stop - Half astern
- Full astern’ the engineers below were blissfully unaware that they had been
given any orders. Luckily a sandbank and some rafts broke the impact but Bulolo
hit the concrete jetty a tremendous crack before finally coming to rest."
Having visited Algiers a couple of times since then, I can testify that the dent
in the jetty wall was still there!
[A typical layout of the room through which incoming radio
signals were received via the array of aerials on deck.]
During the following days,
Bulolo was the centre of activity for the initial
political and military negotiations with the Vichy French authorities (Darlan,
Giraud, etc) and it provided the vital communications link with the American
forces in Casablanca.
After four weeks alongside in Algiers, we
returned to the UK in time for Christmas leave. But Bulolo's North African duty was not quite over. The
Casablanca conference was scheduled for early January 1943, when Churchill and Roosevelt were to discuss plans for
the next stage in the war.
Churchill suspected Roosevelt and his advisers
would be loathe to accept his (Churchill's) wish to continue with the Mediterranean campaign.
They viewed it as an unnecessary diversion that would delay the main invasion of Europe.
Here I quote from an account
of these events by Rick Atkinson in his book An Army at Dawn. ‘ To
help build his case, Churchill had ordered Bulolo to attend at Casablanca. With
its war room full of planning studies bound in red leather dispatch folders,
Bulolo symbolised the British empire’s formidable bureaucratic firepower’.
Here, the British chiefs would lobby their American counterparts, all issues
would be discussed fully and the relentless British logic would win through.
Those red leather folders would reveal ‘wondrously precise studies and
statistics’ in support of Churchill’s strategic arguments! Bulolo’s
intellectual contribution to history seemed secure!
By the time of the ill-fated Dieppe Raid on 19 August, 1942, the idea of HQ
ships had taken hold. For this operation, three Hunt Class Destroyers were
designated HQ Ships.
was the main HQ ship, from which Canadian, Major General,
H F Roberts, MC, commanded the assault force and Captain J Hughes-Hallott, RN, commanded the
naval element. Also on board was WW1 veteran airman, Air Commodore
Adrian Trevor Cole, CBE, MC, DFC, of the Royal Australian Air Force. He controlled the air operations
above the raid
from a forward vantage point. Suitably qualified service personnel drawn from
the three services manned the various communications and control room functions.
was crewed to operate in support of HMS Calpe.
It controlled low fighter cover squadrons under Acting Squadron
Leader, James Humphrey Scott, RAFVR. Berkeley was also designated "First

two became disabled. Prior to her departure
for Dieppe, her battle cry was played over her loud hailer, the sound of which echoed across the
harbour waters to the embarking troops
on the jetties.
commenced in the late evening of 18 August, 1942. The flotilla comprised over
230 ships assembled from ports along the south coast of England. It was a warm,
moonless night as the ships headed across the channel to Dieppe. Radar stations on the English coast picked up "unidentified
vessels" and twice, at 01.30 and again at 02.30 on 19 August,
they radioed warnings to the naval commander, Captain Hughes-Hallet. These
warnings were not acknowledged and the raiding force took no evasive action. The
force commanders were, therefore, unaware they were on a collision course with a
German convoy proceeding from Boulogne to Dieppe.
main assault troops were carried in large ships with their LCPs (Landing
Craft Personnel) hanging from davits. Most of the commandos made the crossing in
their own LCPs, each of which held about 20 men, while the tanks were carried in their own LCTs (Landing Craft Tanks)
with 3 tanks to each LCT. Just after 03.00, the first shots of Operation Jubilee were fired as troops, in the larger ships, were
loaded into their LCPs and lowered into the water for the long run in to the beaches. The
"point of no return" had been reached.
As the action proceeded, Flt/Lt Kidd noted that the Berkeley was hit at 12.45 and began to sink
immediately. HMS Calpe and some smaller craft transferred most of the crew
and service personnel from the vessel and picked up others from the sea. The Berkeley's Captain,
Lt J J S Yorke, RN, and most of his men, survived. Shortly after 13.00, HMS
Albrighton torpedoed the Berkeley and she sank at 13.08.
[Map courtesy of Google Map Data 2017.]
HMS Calpe was attacked and bombed by 3 Dorniers,
which approached from the west at 8,000 ft. They released their bombs at 6,000
ft while Calpe
was undertaking a slow manoeuvre, searching for a downed pilot. Although
there were no direct hits, the blasts damaged the ship's stern, causing some
and blowing six more overboard. They were rescued by SGB 9, a gunboat under
the command of Lt Peter Scott DSC, who was later to become a famed naturalist.
Immediately afterwards, a Folke Wulf 190 approached from the east and strafed
the starboard side of the destroyer, hitting the bridge with cannon fire, killing an Oerlikon
gunner and wounding Air Commodore Cole. He was not the only Air Force casualty
that day aboard the Calpe and the Berkeley. On the
latter, Wing Commander, Stanley Skinner, DFC, Observer for the raid, was killed. He
was a former night-fighter pilot with 604 Squadron. His American counterpart, Col LB Hillslinger,
lost a foot in the action.
The Dieppe Raid
was a disaster for the assault forces but there were also problems at sea. From an altitude of 25,000
feet (about 4.5 miles), pilots of the RAF patrolling the area at around 13.00 could
see the ships at the end of the withdrawing convoy coming under enemy air
attack. They reported that HMS Berkeley was in trouble and requested, via
the Hornchurch controller, that the 'Cover Squadrons' be concentrated in that
area. They also contacted HMS Calpe, recommending that the lower cover
squadrons be directed over the
Berkeley. [For reasons not entirely clear, it seems
that the RAF were unable to respond to these requests.]
A few days after the raid, Flt Lt, Gerald Le Blount Kidd, RAFVR, Close Support Controller aboard HMS Calpe,
reported "Communications worked excellently throughout and great credit is due to
Flight Lieutenant Hall for his work in this connection. He also rendered
invaluable assistance throughout the day as liaison officer between Air
Commodore Cole and me and in other capacities. However, no signals were received by me from Uxbridge, so that it was not known what
targets had been accepted and what squadrons were on their way.
The view the Controller had from the bridge was excellent and invaluable in exercising control over aircraft. HQ ships I and 2 were often a
good distance apart. As there were no fighters under the direct control of HQ 1,
interceptions could not be made in several instances. Difficulty was experienced
in locating the fighters actually under ship control. It was noted that aircraft
in loose pairs and fours had a much better chance of making interceptions than
aircraft in Squadron formation. (This was seen only once). Fighters rarely, if
ever, saw enemy aircraft before they were warned by the Controller. Too often
they were down sun of the convoy and too low and the attacks would be made from
up sun and above. Fighters were often too low and got fired at by the convoy
gunners, who were naturally very light on the trigger. There was a lot of RT
chatter between aircraft. As things turned out, this did not matter but, if closer
control of close support squadrons, or control of fighters, had been required,
intercom would have to be cut to a minimum. Close support at Dieppe had little apparent effect on the houses, which were
My aircraft recognition was
very weak indeed but it was essential that controllers doing this type of work should be adept. It was observed
that enemy aircraft were often chased home by large numbers of our fighters,
many of whom could have had very little hope of catching up. Cover over the
convoy was left very thin on these occasions. Excellent co-operation and
assistance was, at all times, received from Squadron Leader Sprott on HQ 2. Apart
from the fact that, owing to the unforeseen strength and preparedness of enemy
resistance, the objectives were not gained and casualties were high. Nevertheless,
viewed as a Combined Operation, the raid was a success of timing and close co-operation between the services.
The next combined attack will have a much
better chance of success as a result of the great deal of experience gained by
all who took part. Much gratitude is felt for the pilots who looked after the
convoy with such tireless resolve, from the moment of first light until after the
weather had closed down and for the organisation and pre-planning that made
that possible. The Navy's efficiency and courtesy was much appreciated and the
calm and cheerful
courage of the Canadian Officers and men was an inspiration."

The positions of the 5 main HQ Ships (one for each landing beach) are marked
on the D-Day map above.
the Normandy landings there were 3 main categories of HQ ships, each with a range
of tasks appropriate to their function and status. The HQ Ships were
concerned with monitoring progress of the invasion against the overall plan and
directing changes in the light of the battle progress; the
Assault HQ Ships were concerned with providing support over a local
area and were in radio contact with the troops ashore and the Non Assault HQ
Ships were allocated "stationery" tasks such as accommodation, repairs,
engineering and depot.
The latter acted as mobile or
fixed bases for other ships, landing craft, submarines or small craft or in
support of a naval base. They were either specifically designed for their purpose or converted from another
use and were especially useful as bases for submarines, fast attack craft or
small minesweepers, which had little space for the crew to relax.

In the Eastern Task Force, one HQ Ship was assigned to each of the three
Assault Divisions. The ships were positioned seaward of the beaches as follows: off
Gold beachwas HMS Bulolo with Naval Assault Force G carrying the Divisional
Commander of the 50th Northumbrian Division; off Juno beach
was HMS Hilary
with Naval Assault Force J carrying the Divisional Commander of the 3rd Canadian
Infantry Division and off Sword beach was HMS
Largs with Naval Assault Force S carrying the Divisional Commander of the
3rd British Infantry Division.
There were 3 Standby HQ ships;
HMS Albrighton, HMS Royal Ulsterman and HMS
The functions of the ships were;
to act as Flag Ship to the Naval Commander of the assault force
to accommodate the (Army) Military Commander of the assault force
concerned and his staff,
to accommodate the (RAF) Air Staff Officer representing the
Commander of the Advanced Allied Expeditionary Air Force (Advanced AEAF) based
at Hillingdon House, Uxbridge.
The Advanced AEAF was a relatively small
operational organisation, through which air activity over the assault area was
controlled and coordinated. On board each HQ Ship the Air Staff Officer had a Group Captain, a Wing Commander
and a Squadron Leader Signals Liaison Officer to assist in their duties, which
to keep the Commander of the Advanced AEAF informed of the
intentions and requirements of the Navy and Army Commanders,
to give the Military Commander on board advice on requests for
immediate air support or tactical reconnaissance received over the Army
to give advice to the Naval Commander of the Force on air matters
generally but specifically on the use and control of AA fire 24/7 and smoke

Force concerned about the anchorage position of any FDT in his area insofar as
its position affected its operational effectiveness,
as required, directing fighters by visual control on instructions
from the co-ordinating FDT,

The pilots also reported back to the HQ ship on the result of their mission for
the benefit of the Military Commander on board. The HQ ships continued to act as forward control for support aircraft until a
fully operational Group Control Centre had been established in the territory
previously held by the enemy. The three HQ ships continued to operate off the beachhead for a number of
days after D+7, by which time the Air Staff contingent had left as the front line
moved inland. Thereafter the ships' functions were mainly Naval in nature.
The delivery of this formidable list of tasks
was challenging and required many different organisations, a large range of
sophisticated high tech equipment, well trained personnel and a communications
network second to none.
[USS Ancon Flag ship & HQ ship for Omaha beach.]
The organisation and technical equipment
available to the invading force included; the Combined Control Centre
at Uxbridge, which came under the
overall direction of the Commander, Advanced AEAF (see below) under the Air
Officer Commanding No 11 Group, in full collaboration with the Commanding
IX Fighter Command and with representation of the US VIII Fighter Command.
The Uxbridge centre
was manned by both British and US personnel and was situated in the Operations
Room of No. 11 Group, Air Defence of Great Britain, with all the
facilities of this organisation available to them, augmented during the assault phase by
additional communications to US Fighter Units and Fighter
Direction Tenders at sea. The Control Centre planned, coordinated and
controlled all fighter operations and was, in addition, responsible for issuing
executive instructions for Fighter/Bomber operations.
Allied Expeditionary Air Force (ASAF) or Allied Armies' Expeditionary Air
Force (AAEAF). As the name suggests, this was a special organisation to
coordinate Allied air activity over the invasion fleet, landing beaches and
battle grounds. The aim was to achieve the best use of the Allied Air Forces
during the invasion. To achieve this, the AEAF was established at Hillingdon House,
Uxbridge. It was under the general direction of the Commander-in-Chief,
with the Commander AEAF directing and co-ordinating operations of the Ninth US
Army Air Force and the RAF Second Tactical Air Force. However, it failed to be
the controlling HQ for all Allied air forces, since RAF Bomber Command and the US
Eighth Air Force were retained by their national command authorities. For a time,
it was brought under the control of the Supreme Headquarters Allied
Expeditionary Force (SHAEF) but later disbanded when Leigh Mallory was reassigned to
the far east.
Type 15 GCI Radar. The normal mobile GCI
station operating on the 200 megahertz band was very vulnerable to enemy radio
jamming by 'window' (see below) but it was still the best
instrument for the control of night fighters when jamming was not present.
[Photos right & below, of HM the King visiting HMS Largs courtesy of the late
Type 11 Station.
This radar operated between 500 & 600 Megahertz and could be changed within
the frequency range in 5 to 10 minutes. This made it less vulnerable to enemy
jamming and its narrower beam width gave it better discrimination when the enemy
dropped 'window'. Because its performance was inferior to Type 15, it was mainly used as a
The effectiveness of radar could be seriously compromised by saturating the sky
with metallised paper strips cut to half the length of the target radar
frequency. They produce spurious echoes on radar screens, making it extremely
difficult to interpret the data and identify the approach of aircraft.
Army Signals Support Unit (ASSU).
This was the radio channel provided for HQ Ships to pass calls from troop
commanders on the far (enemy) shore to the UK when they required air support. It
was an Army responsibility.
Talk Between Ships (TBS).
Operating between 65 and 85 Megahertz, this naval VHF/RT point to point
equipment was used for communications between the HQ ships, FDTs and the
Combined Control Centre at Uxbridge.
Group Control Unit.
A mobile unit of 4 vehicles which, when set up, formed a square around an
operations table to control fighter aircraft in support of ground forces. The
unit received plot information from mobile radar equipment, which was
relayed to plotters at the table by W/T. There were also facilities within the
unit for planning, intelligence gathering, Army Liaison and Movement Liaison.
Plan Position Indicator (PPI).
The PPI was a cathode ray tube, which gave indications in azimuth through 360
degrees and varying range scales.
Azimuth (navigation)was the angular distance usually measured
clockwise from the north point to the intersection with the horizon of the
vertical circle passing through a celestial body.
Radio Counter Measures
were designed to decrease the effectiveness of the
enemy's radio communications by jamming their frequencies.
provided information on the movement of friendly aircraft, to
allow operation and filter rooms to correctly identify the tracks of friendly
aircraft, to prevent unnecessary air raid warnings and to prevent friendly fire
Air Signal Intelligence ("Y" Service) intercepted enemy R/T and W/T signals to make
operational use of the information. In the case of seaborne landings, the small
units in the FDTs intercepted R/T used by fighters,
fighter/bombers and occasionally bombers. The information was immediately made
available to Fighter Controllers in plain language, where immediate action was
By combining the intercepted messages and Direction Finding (D/F) bearings on
the transmissions made by the "Y" service with radar information, a fairly
complete picture emerged of the size of the formation, area of operation and
bases used by the enemy aircraft.
W/T intercept was not necessary on FDTs, since the information was usually
only of longer term strategic value. However, if required, the information could
be made available to seaborne forces by broadcasting it from a static "Y"
Unlike the main HQ ships, the Assault HQ ships were in touch with troops
ashore. The troops provided information on targets and reported back on the
effectiveness of shelling for the benefit of the warships' gunners. The Assault
HQ ships could also direct minor craft and amphibian vehicles working between
the carrier ships, transports and the shore. The HQ ships also had links, through their air force
personnel, to the crews of fighter bombers and rocket firing aircraft. In turn,
they could be put in direct
radio contact with forward platoons and other junior commanders when specific
strikes were needed in support of advancing infantry and tanks.
As the invasion developed, the Assault HQ ships produced a stream of
directives for changes to the overall plan. For example, 'Bombarding' warships
were given new targets, reserve brigades in some cases were brought ashore more
quickly than planned and a host of minor changes including the provision of hot
food to landing craft crews and the replacement of lost equipment.
HMS Bulolo handled around 2,300 messages per day as they fine-tuned the
grand plan in the light of experience - rough weather,
bottlenecks on beaches caused by obstacles or enemy action, landings in the
wrong places due to navigational errors, breakdowns etc. Where the landings were
delayed or repositioned, it was vital that gunners, acting in support of the
advancing troops, were well aware of the changes to adjust the timing and
targeting of their bombardments. Whatever eventuality arose, the Assault HQ ships were expected to have an
alternative course ready to follow and to advise all interested parties,
including the Admiralty.
A variety of vessels were used, including Cruisers,
Gunboats, Frigates, Destroyers, Converted Passenger Vessels, Yachts and Landing
Craft. They were assigned to the Initial Assault Fleet to serve as Flagships,
Landing Ship HQ (LSH) and Control Vessels. Try Google for more information on

Star of Freedom
HM Trawler Depot Ship + Left Solent, arrived Utah 24 June in Convoy ECB17W.
With the introduction of the Fighter Direction Tenders
(FDTs), the usefulness of the HQ ships, from the RAF point of view, was diminished.
A reduction in personnel and equipment was recommended. However, they did
provide useful visual information on low flying enemy aircraft to the FDTs
and thereby to the low cover fighter aircraft of the Allies. This resulted
in the interception and destruction of three enemy aircraft.
The air situation plot required by the Commodore of each Assault Force
could be adequately provided by information from the FDTs, whose radar was
superior and who had access to the same information sources as the HQ ships.
It was suggested that the filter room on the HQ ships and their personnel
could be "eliminated".
Since the HQ ships would most likely never take over control of the
Fighter cover from the FDTs, it was suggested that "controlling personnel" be
removed from the HQ ships or substantially reduced to two Controllers and
two Deputy Controllers.
In view of the superior radar and comprehensive communications equipment,
it was recommended that the FDTs should initiate Air Raid Warnings with the
HQ ships giving warnings in their own assault areas.
Two separate channels of communications between the HQ ships and FDTs
were essential 24/7, one for plotting and the other for liaison.
2 Diverting Fighters from pre determined missions.
Fighters engaged on direct support were given specific targets before take
off. En route, they were instructed to radio the HQ ship in the area they
were over-flying, to enable the Air Staff Officer, or Controller, on board to
divert them to targets of opportunity. However, in the event there were few
occasions when aircraft were available and, even when they were, the Army
staff had no clear picture of battleground conditions to allow them to
identify suitable targets.
3 Ensuring appropriate high level Army Representation on HQ Ships
An Army officer of sufficient rank should remain on board each HQ ship to
represent the views of the Divisional Commander until the ship ceases to act
as forward control of the Fighter/Bomber forces. The absence of the Military
Commander, and all his senior staff who had gone ashore after H+6,
contributed to the ineffectiveness of this part of the operation. The
remaining Army personnel had insufficient rank and experience to represent
the Army point of view. In future operations involving heavy Air Support for
the Army it was recommended that the Army should have adequate
representation on board the HQ ship until they had handed over control to
shore based establishments.
4 Intelligence Gathering
It was strongly recommended that a full "Y" team be onboard the HQ ships.
5 Training and Familiarisation
The HQ ships should arrive in the assault area three months prior to an
action to allow time to train many hundreds of people, from different
disciplines and geographical locations, to be trained in their own jobs and
to have an understanding of the roles of others they are likely to deal
6 Preparation Time
Officers in charge of the Air Section of HQ ships should be briefed a month
in advance of the action to allow time for them to select maps they require
and to make preparations that cannot satisfactorily be left to the last
7 Knowledge Update
RAF personnel with 18 months continuous service on ships should be given
the option of transfer to land stations to update their knowledge.
8 Naval Assault Radar
The Naval Assault radar reporting had little value without a Movement
Section to identify the tracks.
9 Ceiling on Personnel Numbers
A pre-determined limit on the number of Army and RAF personnel should be set
and adhered to. Many last minute additions were embarked causing
overcrowding, discomfort and the risk of heavy casualties in the event of
damage or sinking.
10 HQ Standby Ships
During the Normandy landings there were three vessels on standby as HQ
ships; HMS Allbrighton, HMS Royal Ulsterman and HMS Dacres.
They were never called upon to undertake the duties and, in hindsight, the
Allbrighton and the Dacres were judged to be too small for the
task. If they were considered necessary, they should be large enough to
accommodate 25 RAF personnel with equipment to receive the FDT plotting
wave, the FDT liaison wave, the Air Command wave, the Air Base wave and the
three Aircraft waves.
11 Approaching Allied Aircraft Alerts
To reduce the risk of Allied aircraft being shot down by friendly fire an
enlarged Movement Liaison Section had been established in No 11 Group Filter
Room at Stanmore. They transmitted by wireless telegraphy coded messages to
HQ ships, FDTs and Operations Rooms on the far shore (as opposed to the home
shore). When the aircraft were 10 minutes flying time from the beaches, one
HQ ship broadcast warnings of the approach of friendly aircraft on the Joint
Forces frequency. This was particularly effective in the case of low flying
aircraft but only when the messages were received and acted upon by all
12 Spotter Plane
In an area thought to have little significance, the HQ ships performed an
important role. Spotter planes working with bombardment ships (reporting on
targets and the accuracy of shell-fire) were, in many cases, unable to speak
directly to the ships concerned. In these circumstances, the pilots were
advised to radio the nearest HQ ship for instructions. The HQ ships provided
a communication link to the bombarding ships or otherwise returned them to
base with their missions unfulfilled. At times there were too many spotter
craft over the anchorage area and it was difficult to co-ordinate their
deployment to the bombarding ships available.
