OCTOBER
1943
ATLANTIC
- OCTOBER 1943
Norway
- Covered by battleships
Anson
and Duke
of York and other units of
the Home Fleet, US
carrier "Ranger" launched air
attacks against
shipping off Bodo, northern Norway
on the 4th. Four ships
were sunk and others damaged.
8th
-
In attacks on Halifax/UK convoy
SC143, "U-610"
or "U-378" sank Polish destroyer
"ORKAN"
(ex-"Myrmidon")
with an acoustic torpedo. Later in
the day RAF and RCAF
air escorts sank "U-419", "U-643"
and "U-610".
16th-17th,
Attacks on Convoys ON206 and
ONS20 - Six
U-boats were lost in exchange for
a single merchantman in
attacks on UK-out convoys ON206
(B6 group) and ONS20 (4th
Escort Group). The 4th EG was
mainly composed of the new
US lease-lend 'Captain' class
frigates. The B7 group
commanded by Cdr Gretton first of
all reinforced ON206.
On the 16th, southeast of
Greenland, RAF
Liberators accounted for "U-470",
"U-844" and "U-964". Next day on
the 17th it
was "U-540's" turn. Shortly after,
as B7
transferred to ONS20,
corvette
Sunflower
sank "U-631" with her Hedgehog.
Still on the
17th, frigate "Byard" with the 4th
EG escorting
ONS20 sank "U-841". Cdr Gretton
then took B7 to support nearby
ON207.
23rd-29th,
Attacks on Convoys ON207 and
ON208 - South of
Iceland, B7 reinforced ON207's
already formidable
escort consisting of the Canadian
C1 group and Capt
Walker's 2nd EG. On the 23rd
a RAF Liberator of No
224 Squadron and B7 destroyers
"Duncan" and
"Vidette" shared in the sinking of
"U-274". Three days later the RCAF
got "U-420". Then on the 29th, by
now with
ON208, B7 ships "Duncan",
"Vidette" and
Sunflower
sank "U-282". In less then two
weeks in attacks
on just four convoys, nine U-boats
had been sunk by the
highly efficient inter-service air
and sea escorts.
31st
-
Northeast of the Azores, destroyer
"Whitehall"
and corvette "Geranium" of the
British B1 group
escorting North and West Africa/UK
convoys MKS28 and
SL138 detected "U-306" by HF/DF
and sent her to the bottom.
Battle
of the Atlantic - After
lengthy negotiations ending
in August 1943, Portugal granted
the Allies the right to
establish air and sea bases in the
Azores as from
October. This greatly extended the
Allies' ability to
cover the central Atlantic and the
convoy routes between
Britain and North and West Africa;
also between North
America and the Mediterranean.
Monthly
Loss
Summary: 13 ships of 61,000 tons
and 1 destroyer; 23 U-boats
including 4 by RAF and US aircraft
in North Atlantic and
off Portugal, 6 by US escort
carriers Card, Core and
Block Island off the Azores and in
mid-Atlantic.
EUROPE
- OCTOBER 1943
Royal
Navy -
Adm of the Fleet Sir Dudley Pound,
First Sea Lord since
1939, suffered a stroke in August
1943 at the time of the
Quebec conference. He resigned and
died on 21st
October - Trafalgar Day. Adm
Fraser was offered the post
as Winston Churchill's first
choice, but declined, and
Adm Sir Andrew B. Cunningham
filled the Navy's most
senior position on the 15th.
23rd,
Operation 'Tunnel' -
Cruiser "Charybdis",
accompanied by two fleet and four
'Hunt' class
destroyers, sailed from Plymouth
to intercept a German
blockade runner off the coast of
Brittany. Early in the
morning the force was surprised by
a group of torpedo
boats.
CHARYBDIS
was
hit
twice by torpedoes fired by
"T-23" and "T-27" sinking with
heavy
loss of life. 'Hunt' class escort
destroyer
"LIMBOURNE"
followed her after a hit by
"T-22".
Eastern
Front
- In the Centre and
South the
Russians made little progress
against fierce German
resistance. Further South
still the remaining
German troops in the Caucasus
evacuated the Taman
Peninsula and were ferried across
to the Crimea.
MEDITERRANEAN
- OCTOBER 1943
Mediterranean
Fleet - Adm Sir John H. D.
Cunningham succeeded Adm
Sir Andrew Cunningham as C-in-C in
the middle of the
month - they were not related.
Early
October - Two RN submarines
failed to return from
patrol in the month. The first was
"USURPER"
which left
Algiers on 24th September for the
Gulf of Genoa, and
failed to answer a signal on the
11th. She may have been
mined or fallen victim to German
A/S forces.
Mid-October -
"TROOPER"
set out from Beirut in the Lebanon
on 26th September for Dodecanese
patrol and did not get
back on the 17th. German records
claim she was sunk by a
Q-ship off Kos on the 14th.
Italy
- British units of the US Fifth
Army entered Naples on
the 1st as the Germans fell back,
ready to make the
Allies fight long and hard for
every gain over the next
eight months. As they held the
line of the Volturno River
in the west and the Biferno River
in the east, they
prepared their main defences - the
Gustav Line -
along the Garigliano and Rapido
rivers below Monte
Cassino, and on to Ortona on the
Adriatic coast. On the west,
Gen Mark Clark's Fifth Army
managed to fight its way
across the Volturno by mid-month
and then came up against
the formidable defences in
front of the main
Gustav Line. On the east,
Gen Montgomery's Eighth
Army had to cross a number of
well-defended rivers before
reaching the Line. By the end of
the month he was over
the Biferno and starting to cross
the Trigno. While the
struggle continued, Italy
declared war on Germany
on the 13th.

British
Aegean
Campaign - On the 3rd,
German troops landed on
British-held Kos, which fell next
day. More German forces headed for
the Kos and on the 7th
a convoy of seven small ships and
one escort was
annihilated by cruisers
Penelope
and
Sirius
and two destroyers. As they
withdrew
through the Scarpanto Strait,
"Penelope"
was
damaged
in attacks by Ju87s and
Ju88s. More sweeps and more supply
trips led to further
losses, particularly amongst the
'Hunts', through to
November: 9th - Returning
from a sweep west of
Kos, cruiser "Carlisle" and
destroyers were
dive-bombed in the Scarpanto
Strait area by Ju87 Stukas.
CARLISLE
was
seriously
damaged and never fully
repaired; destroyer
"PANTHER"
was
sunk.
17th - Cruiser
Sirius
was
damaged
by bombs south of Scarpanto
Strait. 22nd - Greek
'Hunt'
"ADRIAS"
(right - CyberHeritage)
was
badly
damaged off Kos on mines laid
by the German "Drache", and as
sister ship
"HURWORTH"
went to her aid,
was also mined. She sank with
heavy casualties.
"Adrias" was not repaired.
24th
- Destroyer
"ECLIPSE"
fell victim to the same minefield.
30th - Cruiser
Aurora
was
damaged
in bombing attacks.
31st
-
Five German U-boats set out for
the Mediterranean, but
one was sunk by the RAF while
still in the Atlantic and
two were disposed of by Gibraltar
air and sea patrols. On
the 31st destroyer
"Douglas" and trawlers
"Imperialist" and "Loch Oskaig"
sank
"U-732" off
Tangiers.
The
second sinking was on the first
day of November.
Monthly
Loss
Summary: 9 British or Allied
merchant ships of 46,000
tons
INDIAN
& PACIFIC OCEANS - OCTOBER
1943
New
Guinea
- Finschhafen was taken on the
2nd, but fighting
continued in the area right
through until December 1943
when the Australians started
pushing slowly along the
north coast towards Madang in
parallel with their drive
further inland.
North
and
Central Solomons,
Battle
of Vella Lavella
- As nine Japanese destroyers
completed the evacuation of the
island on the night of
the 6th/7th, they were intercepted
by three US ships. A
destroyer an each side was lost.
In preparation for the
invasion of the northern Solomons
island of Bougainville,
New Zealand troops were landed on
the Treasury Islands on
the 27th.
German
Raiders - The last
operational German raider was sunk
on the 17th. Heading for Japan,
"MICHEL"
was
torpedoed
off Yokohama by US submarine
"Tarpon". Since leaving Europe in
March 1942
she had accounted for 18 ships of
127,000 tons.
Merchant
Shipping War - RAF aircraft
sank their second
U-boat of 1943 in the Indian Ocean
with "U-533" on the 16th in the
Gulf of Oman.
Monthly
Loss
Summary: Indian Ocean - 6 merchant
ships of 26,000
tons; Pacific Ocean - 1 merchant
ship of 7,000 tons
NOVEMBER
1943
ATLANTIC
- NOVEMBER 1943
6th
-
Capt Walker's Escort Group with
escort carrier
"Tracker" patrolled east of
Newfoundland in
support of convoy HX264. "U-226"
was
sighted
by "Tracker's"
aircraft and destroyed by sloops
"Starling",
"Kite" and "Woodcock". Shortly
after,
"Starling" this time with "Wild
Goose", accounted for "U-842".
19th-25th,
Attacks on the UK/ North and
West Africa Convoy Routes - Combined
UK-bound convoys MKS30 and
SL139 were escorted by the 40th
Escort Group and joined
in turn by the 7th, 5th and 4th
EG's to the far west and
northwest of Portugal. One
merchantman was lost to air
attack, but three U-boats went
down in the fighting: 19th
- "U-211" to a RAF Wellington. 20th
-
Frigate "Nene" and Canadian
corvettes
"Calgary" and "Snowberry" of the
5th
EG sank "U-536". 21st -
Frigate "Foley"
and sloop "Crane" of the 40th EG
accounted for "U-538". Northwest
of Cape Finisterre,
Hs293 glider bombs sank the one
merchant ship lost. The
surviving U-boats were next
deployed against other
convoys in the area. As the
U-boats approached southbound
convoys KMS30/0S59 they ran into
the 4th EG, which had
also been diverted: 23rd - Frigates
"Bazely",
"Blackwood" and
"Drury" sank "U-648". 25th
- Two days later
"Bazely" and "Blackwood" sank
"U-600". Later, in the same area
around
the Azores, a RAF Wellington
accounted for "U-542", and
aircraft from US escort
carrier "Bogue" the "U-86".
Russian
Convoys - For the
first time since March 1943,
Russian convoys sailed -
setting out and arriving at the
end of the month and in
early December. Convoys JW54A
and JW54B to
Kola Inlet, and return RA54A and
RA54B
passed through a total of 54 ships
without loss.
Monthly
Loss
Summary: 7 ships of 28,000
tons and 1 US destroyer
off the Azores; 16 U-boats
including 2 by RAF and US Bay of
Biscay air patrols, 2 by RAF in
North Atlantic and off
the Azores, 3 by US forces in
mid-Atlantic and off
Ascension in the South Atlantic.
EUROPE
- NOVEMBER 1943
Air
War
- RAF Bomber Command launched the
Battle of Berlin with
heavy raids in the middle of the
month. This was the
first of 16 major attacks on the
German capital through
to March 1944.
Eastern
Front - In the Centre/South,
Russian forces
captured Kiev, capital of the
Ukraine on the 6th and
pushed on. However, the Germans
managed to counter-attack
and recaptured some of the towns
to the west of the city.
A larger German counter-offensive
in the same area faded
out by early December. Further
South the attacks
towards Odessa finally cut off the
Germans in the Crimea
where they held out until May
1944.
Merchant
Shipping War - E-boats and
mines were still
capable of taking a toll of
coastal shipping. On the
night of the 4th/5th, Channel
convoy CW221 lost three
ships off Beachy Head to E-boat
attack, and later in the
month two more were mined off
Harwich.
Monthly
Loss
Summary: 7 British, Allied and
neutral ships of
13,000 tons in UK waters.
MEDITERRANEAN
- NOVEMBER 1943
1st
-
The second U-boat lost to the
Strait of Gibraltar
defences following the sinking the
day before was "U-340" to
destroyers "Active"
and "Witherington", sloop
"Fleetwood"
and RAF aircraft of No 179
Squadron.
Italy
- In the west, Fifth Army
struggled to make
progress towards the main Gustav
Line but was still short
of the Garigliano River and
Cassino. To the east,
Eighth Army was over the Trigno
and preparing to attack
new German positions behind the
Sangro River. A major
offensive was launched on the 28th
led by British and New
Zealand troops with the aim of
breaking through the East
End of the Gustav Line and taking
Ortona. Luftwaffe Field
Marshal Kesselring was given
command of all German forces
in Italy. Right through until the
end of 1944 he was
responsible for the stubborn and
skilful defence of the
country against strong Allied
attacks.
British
Aegean
Campaign, Conclusion -
German forces landed on
Leros on the 12th and captured the
Island after four
day's heavy fighting against the
British and Italian
defenders. The campaign came to an
end when Samos was
evacuated on the 20th, but not
before two more 'Hunts'
fall victim, this time to Hs293
glider bombs: 11th -
"ROCKWOOD"
was
severely
damaged off Kos following an
attack with other destroyers on
Kalymnos (Calino). She
was not repaired and went into
reserve. 13th -
"DULVERTON"
was
sunk
off Kos as she withdrew from
searching for German shipping
making for Leros. The cost
of this abortive campaign to the
Royal Navy could now be
added up - four cruisers damaged
with one never repaired,
six destroyers lost or permanently
out of action and
others damaged. In addition the
small Greek Navy had lost
two destroyers.
Mid-November
- Submarine "SIMOOM"
sailed from Port
Said on the 2nd for the Aegean and
failed to answer a
signal on the 19th. She was
presumed mined although
German records claim she was
torpedoed by
"U-565" off Kos on the 15th.
28th
-
On passage through the
Mediterranean to join the Eastern
Fleet, cruiser
Birmingham
was
badly
damaged northwest of Derna by
"U-407".
Cairo
and
Teheran Conferences - On
their way to Teheran to meet
Marshal Stalin, Winston Churchill
and President Roosevelt
first stopped over at Cairo to
discuss operations in
Burma and China with Chinese
Generalissimo Chiang
Kai-Shek. Arriving at Teheran on
the 28th, the agenda
included the Allied invasion of
Normandy and southern
France, and Russia's agreement to
declare war on Japan
once the Germans were defeated.
Monthly
Loss
Summary: 10 British or Allied
merchant ships of
68,000 tons
INDIAN
& PACIFIC OCEANS - NOVEMBER
1943
Bougainville,
Northern
Solomons - The large
Japanese island
garrison was mainly established in
the south and so US
Marines were landed on the weakly
defended western side
near Empress Augusta Bay on the
1st. They soon had a
large beachhead, and it was not
until March 1944 that the
Japanese mounted a strong
counter-attack. Two main naval
battles resulted in November:
Battle
of
Empress Augusta Bay
- Japanese force of four cruisers
and six
destroyers sailed to attack the
invasion shipping. On the
night of the 1st/2nd in a confused
night action with four
US light cruisers and eight
destroyers, the Japanese were
driven off with the loss of a
cruiser and destroyer.
Battle
of Cape
St George
- Five
Japanese 'Tokyo Express'
destroyers headed for the
Bougainville area and early on the
25th were intercepted
by five US destroyers off the
southern tip of New
Ireland. Three of the Japanese
were sent to the bottom in
the last of the numerous and
hard-fought Solomon Islands
actions that started only 15
months earlier with the
Battle of Savo Island.
12th
-
On patrol off Penang, Malaya in
the Malacca Strait,
submarine "Taurus" sank the
Japanese "I-34" sailing on a
supply trip to
Europe.
British
Gilbert
Islands, Central Pacific -
US forces now
started the advance through the
Central Pacific with the
invasion of the Gilbert Islands.
Under the overall
command of Adm Nimitz, C-in-C
Pacific Fleet, Adm
Spruance's Fifth Fleet landed US
Marines and Army troops
on the atolls of
Tarawa
and
Makin
respectively on the 20th. Both
were strongly defended but US
losses on Tarawa were
particularly heavy, although as
usual few Japanese
survived. Both atolls were secured
by the 23rd. Next day,
escort carrier "LISCOME BAY"
was
sunk
off Makin by a submarine. The
next step would be to the Japanese
Marshall Islands lying
to the northwest.
Monthly
Loss
Summary: Indian Ocean - 4 merchant
ships of 29,000
tons; Pacific Ocean - 1 merchant

DECEMBER
1943
ATLANTIC
- DECEMBER 1943
24th
-
Destroyer "HURRICANE"
of the 1st EG with UK/African
convoys OS62 and KMS36 was
torpedoed by "U-305"
or "U-415" northeast of the
Azores. She was
scuttled next day.
26th,
The Battle
of North Cape and
Russian
Convoy JW55B
(see
map above)
-
Russian convoys were still
sailing
in two sections. JW55A
left Loch Ewe, Scotland on
the 12th and arrived
safely with all 19 merchant
ships on the 20th. Adm
Fraser with
Duke
of York went right through
to Russia for the first
time before returning to Iceland.
Convoy JW55B,
also with 19 ships, sailed for
Russia on the 20th - three
days later return convoy RA55A
(22 ships) set out.
Cover for both convoys through the
Barents Sea was to be
provided by Vice-Adm R. L. Burnett
with cruisers
Belfast,
Norfolk
and
Sheffield
which left Kola
Inlet on the same day as RA55A -
the 23rd. The
Admiralty expected the 11in-gunned
battlecruiser
"Scharnhorst" to attack the
convoys and Adm
Fraser with "Duke of York" and
cruiser
Jamaica
left Iceland and headed for the
Bear
Island area. "Scharnhorst"
(Rear-Adm Bey) and
five destroyers sailed
from Altenfiord late on
the 25th, Christmas Day.
Early next morning JW55B
was 50 miles south of Bear
Island, the weather
stormy, as the Germans headed
north to intercept.
Meanwhile Adm Fraser
was
200
miles away to the southwest as Adm
Burnett's cruisers
approached
the convoy from the east. At 07.30
on the 26th the German
destroyers were detached to
search for the convoy, failed to
make contact and were
later ordered home. They played no
part in the battle.
First
contact
was
just before
09.00 on the 26th when
"Belfast" detected "Scharnhorst"
by
radar as she was heading south and
only 30 miles east of
the convoy. "Norfolk" engaged and
hit the
battlecruiser which turned north
and away to try to get
around to JW55B. Adm Burnett
anticipated this move and
instead of shadowing, carried on
towards the convoy.
"Belfast" regained contact at noon
and
all three cruisers opened fire. In
the next 20min "Scharnhorst"
was
hit
and "Norfolk" badly damaged by
11in shells. The
German ship now headed south away
from the convoy as Adm
Burnett shadowed by radar. At this
time, Adm Fraser
was
now
to the south-southwest and in a
position to cut off her retreat.
He made radar contact
soon after 16.00 at a
range of 22 miles and closed
in. Fifty minutes later at 1650,
"Belfast" illuminated
"Scharnhorst"
with starshell and Adm Burnett's
cruisers engaged from
one side and "Duke of York" and
"Jamaica" from the
other. Hard hit, especially by the
battleship's 14in
shells, the German ship's main
armament was eventually
silenced. Finally the cruisers and
accompanying
destroyers fired torpedoes, 10 or
11 of which struck
home, and soon after 19.30
"SCHARNHORST" went down. Only 36
men could be
rescued. Now only "Tirpitz"
remained as a
potential big ship threat to the
Russian convoys. On the 29th
JW55B reached Kola safely. Return
convoy RA55A was well
clear of Bear Island by the time
the battle had started
and made Loch Ewe on 1st
January. The second
return half - RA55B of
eight ships - left Russia
on the last day of the year and
got in on 8th January.
Monthly
Loss
Summary: 7 ships of 48,000
tons and 2 destroyers
including one US in the North
Atlantic; 1 German battlecruiser
and 5
U-boats including 1 by RAF Bay of
Biscay patrol, 3 by US
Navy in Azores and Madeira areas,
1 scuttled after storm
damage in mid-Atlantic.
EUROPE
- DECEMBER 1943
28th,
Battle in the Bay of Biscay - Eleven
German destroyers and
torpedo boats sortied into the Bay
of Biscay to bring in
the blockade-runner "Alsterufer".
She was sunk
by a Czech liberator of RAF
Coastal Command on the 27th,
and next day as the German
warships returned to base they
were intercepted by 6in cruisers
Glasgow
and
Enterprise.
Although outnumbered and
out-gunned they sank 5.9in-gunned
destroyer "Z-27" and torpedo boats
"T-25" and "T-26". This marked the
virtual end of
German attempts to bring in vital
supplies from the Far
East by surface ships. Since 1941,
of 35 ships that had
set out, only 16 broke through
Allied patrols.
Normandy
Invasion
- In late December the
commanders for the
invasion of Europe were announced.
US General Eisenhower
would be Supreme Allied Commander
with Air Marshal Tedder
as deputy. In charge of all naval
operations under the
code name 'Neptune' was Adm Sir
Bertram Ramsey.
Eastern
Front - Since October 1943,
five Russian attacks in
the Centre had been
launched against the Germans
west of Smolensk. The greatly
outnumbered defenders held
on, but the Russians now had a
foothold back in
Byelorussia. In the Centre/South
all the Ukraine
east of the Dnieper River together
with deep bridgeheads
across much of its length were now
in Russian hands. They
prepared to recover the rest of
the Ukraine, push into
the Crimea and move on Poland and
Rumania.
Monthly
Loss
Summary: 1 merchant ship of 6,000
tons in UK waters.
MEDITERRANEAN
- DECEMBER 1943
Italy
- Fifth Army continued its bloody
struggle in the west
of the country towards the Gustav
Line, but had only just
reached the Garigliano River and
was still short of
Cassino and the Rapido River.
Meanwhile Eighth Army
breached the Line in the east
and the Canadians
had taken Ortona, where the Allies
remained until June
1944. Gen Montgomery, Eighth Army
commander now returned
to England to prepare for his part
in the Normandy
invasion. Gen Eisenhower also
headed for England and Gen
Sir Henry Maitland Wilson
succeeded him as Supreme Allied
Commander, Mediterranean. Later,
in November 1944, Field
Marshal Alexander took over this
post.
War
at Sea
- With the surrender of the
Italian fleet, the big ships
of the Royal Navy were released
for the Eastern Fleet and
to prepare for the landings in
Normandy. The remaining
smaller vessels continued to
escort the convoys needed to
supply the Allied forces in Italy,
and to support both
Fifth and Eighth armies on their
seaward flanks. The RN
also went over to the offensive
against Germany supply
traffic down the west coast of
Italy and also from the
northeast through the Adriatic to
Yugoslavia. From bases
such as Corsica and Bari, light
and coastal forces struck
regularly at shipping, and also at
land targets along the
coast of Yugoslavia in support of
Tito's partisan armies.
A
major disaster marred these
successes on the 2nd when an
air raid on Bari blew up an
ammunition ship, with 16 more
merchantmen lost in the resulting
fires.
11th-16th,
U-boats attacks on UK/North
Africa Convoy KMS34 - Attacks
were made on the convoy off the
Algerian coast using acoustic
torpedoes: 11th -
"U-223" damaged frigate
"Cuckmere". 12th -
Northeast of
Bougie, "U-593" sank 'Hunt' escort
destroyer
"TYNEDALE".
A long hunt ensued by escort
destroyers "Calpe" and "Holcombe"
and
US destroyers "Benson", "Niblack"
and
"Wainwright", in the course of
which the U-boat
managed to sank
"HOLCOMBE".
13th - After more than 30
hours the escorts finally sent
"U-593" to the bottom. Other US
destroyers
including "Niblack" sank "U-73" on
the 16th. This was the 23rd
U-boat lost in the Mediterranean
in 1943.

INDIAN
& PACIFIC OCEANS - DECEMBER
1943
Burma
- Under Adm Mountbatten, Supreme
Allied Commander South
East Asia, Gen Slim's 14th Army
prepared for a major
offensive into northern Burma from
the area of Kohima and
lmphal in India. Preceding this
would be a Second
Arakan campaign to the
south, and in the far north a
parallel Chindit and
American/Chinese operation in part
to open a new route to the Burma
Road from Ledo in India.
The Arakan push started late in
December. Throughout the
rest of the war, Adm Mountbatten's
plans to prosecute the
campaign even more vigorously in
South East Asia were
continually frustrated by his lack
of amphibious
capability.
New
Britain,
Bismarck Archipelago - Gen
MacArthur was
ready to complete his part in the
isolation of Rabaul by
preliminary landings on the
southwest coast of
New
Britain,
followed by a major assault at
the western tip of Cape Gloucester
on the 26th. Cover was
partly provided by Rear-Adm
Crutchley with cruisers
Australia
and
Shropshire.
Fighting continued until March
1944 when, assisted by
further landings, the western
third of the island was
secured. By November 1944, when
Australian troops
relieved the US forces,
considerable numbers of Japanese
were still penned in around Rabaul
where they stayed
