1939
SEPTEMBER
1939
German
Codes - The
British Code & Cipher School moved
to Bletchley Park,
England, the site of its magnificent
successes breaking
the German
Enigma codes through
the
'Ultra' programme .
The school built on the work of Polish
and later French
code-breakers. By April 1940 the first
low level
Luftwaffe codes were being deciphered.
Many months
followed before comparable progress was
made with Naval
codes.
OCTOBER
1939
Americas
- The Pan-American
Conference established
a 300-mile plus security zone off the
coasts of the
Americas within which all hostile action
by the
belligerent powers was forbidden.
NOVEMBER
1939
United
States - The
Neutrality
Act was
amended to allow the supply of arms
to belligerents on a 'cash and carry'
basis. At the same
time American shipping was banned from
the war zones.
1940
MARCH
1940
Canadian
Politics -
William
MacKenzie King, Prime
Minister of
Canada was reelected
by a massive majority in support of
the government's war policies.
APRIL
1940
Atomic
Bomb - Just
as the “phoney war” ended in Europe (it
never
existed at sea) the end of the war was
foreshadowed when
the British government established the
Maud Committee to
oversee nuclear research. Similar steps
had already been taken in
the United States, all of which
eventually led to an
operational atomic bomb.
German
Codes - The
Bletchley Park Ultra programme
was
now
decoding some Luftwaffe low-level Enigma
codes, partly
because of poor German security
procedures. There was
little evidence the hard-won information
influenced the
war over the next two violent months.
MAY
1940
British
Politics -
Following a 10th May House of Commons
debate on the
Norwegian campaign, Prime Minister
Neville Chamberlain
resigned and Winston Churchill assumed
leadership.
JUNE
1940
German
Codes - 'Ultra'
was
now breaking the Luftwaffe Enigma
codes with some regularity, and early in
the month had
its first major breakthrough when
supporting evidence for
the Knickebein
navigation aid for
bombers was obtained. Army codes were
more secure because
of the greater use of land lines for
communications, and
the Naval ones were not penetrated until
mid-1941.
AUGUST
1940
Royal Navy
Codes - These
were changed and for the first time RN
operational
signals were
secure
from German interception and decoding.
It was another
three years before the convoy codes were
made safe from the German
SEPTEMBER
1940
United
States -
After months of negotiations, a
"Ships-for-Bases" agreement was
announced on the 5th
for the transfer of 50 old but valuable
US destroyers to
the Royal Navy in exchange for British
bases in
Newfoundland, Bermuda, the West lndies
and British
Guiana. The first of the "flushdeckers"
arrived
in Britain towards the end of the month.
Battle
of
the Atlantic - The
German decoding B-Service
was
instrumental
in directing U-boats
to convoys.
Axis
Powers -
Germany, Italy and Japan signed the
Tripartite Pact in Berlin on the 27th.
They agreed
to jointly oppose any country joining
the Allies at war -
by which they meant the United States.
NOVEMBER
1940
United
States - Franklin D.
Roosevelt was
elected
to an unprecedented third term of office
as President of
the United States.
1941
MARCH
1941
United
States - The
Lend-Lease
Bill
was passed
into law.
Britain and her Allies would be able to
receive American
arms and supplies without immediate
payment.
Battle
of Cape Matapan - As ships of
the
Mediterranean
Fleet covered troop movements to Greece,
'Ultra'
intelligence
was
received
reporting
the sailing of an Italian battlefleet
with one
battleship, six heavy and two light
cruisers plus
destroyers to attack the convoy routes.
In the battle
that followed, one Italian battleship
was damaged and
three heavy cruisers and two destroyers
sunk for the loss
of one Royal Navy aircraft.
Eastern
Europe and
Balkans - Bulgaria joined
the Tripartite Pact on the 1st March and
German troops
marched in. As of now, only Yugoslavia
in the
Balkans retained national independence
for a few days
more. On the 25th Yugoslavia joined the
Tripartite Pact, but two days later an
anti-Nazi
coup toppled the Government.
MAY
1941
Capture
of "U.110" and the
German Enigma - South
of
Iceland, "U.110" attacked Liverpool-out
convoy OB318. Blown to the surface by
depth charges from
corvette "Aubretia" on the 9th,
"U-110's" crew abandoned ship, but she
failed
to go down. A boarding party from
destroyer
"Bulldog", led by Sub-Lt Balme, managed
to get
aboard. In a matter of hours they
transferred to safety
"U-110's" entire Enigma package - coding
machine,
code books, rotor settings and charts.
The priceless Enigma material
represented one of the greatest
intelligence coup ever
and a major naval victory in its own
right.
"U-110's" capture was far and away the
most
successful of the attempts to capture
Enigma codes. In
the March 1941 raid on the Norwegian
Lofoten Islands,
spare coding
rotors were found.
Then two days before the "U-110"
triumph, a
cruiser force tried to capture the
weather trawler
"Munchen" off Iceland. At the end of the
coming
June a similar operation was mounted
against the
"Lauenberg". In both cases useful papers
were
taken but the real breakthrough
only came with "U-110".
Germany
- Rudolf Hess, Hitler's deputy,
flew to Britain
on his self-appointed peace mission. He
was imprisoned in
Britain and disowned by Germany
JUNE
1941
Atomic
Bomb - The
report on nuclear research by the Maud
Committee led to
the setting up of a development
programme by Imperial
Chemical Industries. Code named 'Tube
Alloys', it oversaw
both
atomic bomb and reactor work.
AUGUST
1941
Anglo-US
Talks -
Winston Churchill crossed the Atlantic
in battleship
"Prince of Wales" to meet President
Roosevelt
off Argentia, Newfoundland between the
9th and 12th.
Together they drafted the Atlantic
Charter setting out their aims for war
and
peace. This was signed by Britain, the
United States and
13 Allied governments in September.
OCTOBER
1941
Japan
- War
Minister Gen Tojo
became Japanese Prime Minister.
Australia
- The Country Party of former Prime
Minister Robert
Menzies who resigned earlier in August
fell from power. John Curtin and the
Labour Party took over.
1942
JANUARY
1942
Arcadia
Conference -
In late December and early January,
Winston Churchill and
President Roosevelt with their Chiefs of
Staff met in
Washington DC. They agreed to the
setting up of a
Combined Chiefs of Staff Committee and
to the defeat of
Germany as the first priority. On 1st
January the United Nations Pact
embodying the principles of the
Atlantic Charter was signed in
Washington by 26
countries.
War Crimes
- The 'Final Solution' for the
extermination of all
European Jews was presented to Hitler.
As large-scale
transportation got underway, a number of
main camps,
including Auschwitz, were prepared for
this foul work. By
war's end, 6,000,000 men, women and
children had been
killed.
Allied
Command,
SE Asia - Early in the month,
Gen Wavell
was
appointed to command ABDA
(American, British, Dutch, Australian)
forces responsible
for holding Malaya and the Dutch East
Indies.
FEBRUARY
1942
Battle
of
the Atlantic - The
Royal
Navy suffered a major setback when
U-boats in the
Atlantic changed from the Enigma 'Hydra'
code to 'Triton'. This was not
broken until December 1942 - a ten month
delay.
JUNE
1942
Anglo-US
Talks -
Winston Churchill flew to Washington DC
for another
series of meetings with President
Roosevelt. They agreed
to share nuclear
research and
concentrate the work in the United
States.
The resulting 'Manhattan Project'
was
put
under military control in
September 1942. Agreement did not come
so easily on the
question of where to open a Second Front
in 1942. The
Americans wanted to land in France to
take pressure off
the Russians, but the British considered
this impossible
at present and proposed the invasion of
French North
Africa. The President did not come to
accept this until
July. Planning then started on what
became Operation
'Torch'.
Czechoslovakia
- Reinhard Heydrich, German
'Protector' of
Czechoslovakia died from wounds
sustained in an
assassination attempt in May. In part
reprisal, the
village of Lidice was wiped out and its
people murdered.
Battle
of
Midway -
On the
4th/5th in a close run battle, four
Japanese carriers - "AKAGI", "HIRYU",
"KAGA" and "SORYU" went down. The US
"YORKTOWN"
was
badly
damaged and finished off by a
Japanese submarine on the 7th. The
Japanese forces
retreated, Midway was spared, and the
Allies had their
first major strategic victory of World
War 2. The
American Navy's successful dispositions
were helped by
the breaking of the Japanese naval codes
DECEMBER
1942
Atomic
Bomb - The
world's first atomic reactor went
critical at Chicago University. By now
problems had arisen over the sharing of
the US work with
Britain.
1943
JANUARY
1943
Air
War
- RAF Bomber Command by night and
increasingly the USAAF
by day mounted a growing attack on
Germany and occupied
Europe. As agreed at the Casablanca
Conference, U-boat bases and their
production centres would be major
targets in 1943.
Casablanca
Conference -
Prime Minister Churchill and President
Roosevelt with
their Chiefs of Staff met for this
important conference.
Major areas for discussion included
the European invasion in
1944, landings in Sicily and Italy after
the Tunisian
campaign, the bombing of Germany and the
continuation of
the war in Burma and the Pacific. Losses
due to U-boats
and the shortage of shipping proved to
be significant
constraints on Allied plans. At this
time the two Allied
leaders announced a policy of
unconditional surrender of the
Axis powers.
APRIL
1943
War Crimes
- The
site of the massacre of Polish officers
was found at Katyn near Smolensk: the
Russians and
Germans accused each other of the
atrocity. In Poland
itself the surviving Jews of the Warsaw
Ghetto rose up against the Germans. SS
troops were called in and by May the
struggle was over.
Those Jews not killed in the fighting
were sent to extermination camps.
'The Man
Who Never
Was'- Submarine "Seraph" released
the body
of a supposed Royal Marine officer into
the sea off
Spain. His false identity and papers
helped to persuade the Germans
that the next Allied blows would fall on
Sardinia and
Greece as well as Sicily.
Japanese
Navy - Adm
Yamamoto, Commander of the Japanese
Combined Fleet was
killed when his aircraft was ambushed
and shot down over
Bougainville in the northern Solomons.
His travel plans
were known in advance through decoded
intercepts. Since
1940 the American code-breakers had been
able to read the Japanese 'Purple'
diplomatic and command ciphers.
MAY
1943
Anglo-US
Talks -
Winston Churchill travelled in the
troopship "Queen
Mary together with 5,000 German POWs for
the Trident Conference, the third major
meeting in
Washington DC. The invasion of Sicily
had now been agreed
and he pressed for follow-up landings in
Italy. The
cross-Channel invasion of Europe
continued to be a major
topic of discussion and D-day was set
for May 1944.
The
Dambusters' Raid
- On the night of the 16th/17th, Wg Cdr
Guy Gibson leds
No 617 Squadron in the famous raid on
the Ruhr dams. Two
dams were breached by Barnes Wallis'
bouncing bombs, but the damage to German
industry
was not great.
JUNE
1943
Battle
of
the Atlantic - The
Royal Navy finally changed the British
convoy
codes and made them
secure against the work of the German
B-Service. In
contrast, the British 'Ultra' work was
fully integrated
into the Admiralty U-boat Tracking Room,
and an almost
complete picture of German Navy and
U-boat operations was
available.
AUGUST
1943
Canada
- Prime Minister MacKenzie King of
Canada hosted the Quebec Conference
"Quadrant' series of meetings
in the middle of the month to discuss
Allied strategy.
Winston Churchill and Franklin Roosevelt
agreed the
outline plans for 'Overlord' - the main
invasion of
Europe - including the use of 'Mulberry'
harbours, and to an American being the
supreme commander. In the Far East, a
South East Asia
Command was to be set up with Adm
Mountbatten as supreme
commander and a second Chindit operation
mounted in
Burma. Agreement was also reached on the
sharing of nuclear research.
Aerospace
War - On the night of the 17th the
RAF inflicted
damage on the German rocket research
establishment at Peenemunde on the
Baltic coast.
Australia
- John
Curtin was re-elected
Prime Minister and the Labour Party
returned to power.
NOVEMBER
1943
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.
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. 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.
1944
FEBRUARY
1944
Norway
- Norwegian
resistance fighters sank a cargo of
heavy water bound for
Germany for nuclear research.
MAY
1944
Aerospace
War - A V-2 rocket crashed near
Warsaw and resistance
groups managed to arrange for the parts
to be
successfully airlifted to Britain.
JUNE
1944
Normandy
Invasion -
Partly because
of elaborate deception plans, partly
because of poor weather,
both strategic and tactical surprise was
achieved.
Aerospace
War - On
the 13th the first V-1 flying bomb
landed on London at the start of a
three-month campaign against southeast
England. Amongst
the weapons shortly used against them
was Britain's first jet
fighter, the Gloster
Meteor. By then Germany's Me262 jet
fighter-bomber had been in action
against Allied
bombers.
JULY
1944
International
Conferences
- Two major conferences were held
in the
United States, starting in July with
monetary and
financial affairs at Bretton Woods, New
Hampshire,
leading to the setting up of the
International
Monetary Fund (IMF)
and the International Bank for
Reconstruction &
Development. In August, talks started at
Dumbarton Oaks
just outside Washington DC, on the
establishment of the United Nations
Organisation (UNO).
Germany
- In the 20th July Bomb Plot, a device
left by Col von
Stauffenberg in Hitler’s East Prussia
headquarters
only injured him slightly. In revenge
many died and Field
Marshal Rommel, implicated in the
attempt on Hitler's
life was forced to commit suicide in
October 1944.
Japan
- The fall of
Guam and Tinian in the Marianas to US
forces had
political consequences. Gen Tojo's
government resigned, but a cabinet
apparently just as committed to
continuing the war came
to power.
SEPTEMBER
1944
Canada -
At the
second Quebec
Conference, Prime
Minister Churchill and President
Roosevelt reviewed the
progress of the war. They agreed the
British Pacific
Fleet will serve under American Command.
Atomic
Bomb - Far
across North America in the southwest,
the massive atomic bomb
programme approached
its climax at Los Alamos, New Mexico.
Although
intelligence reports suggested Germany
had made little
progress with nuclear research, the
by-now mainly
American work continued and a B-29
Flying Superfortress bomber unit was
formed to train for the
dropping of this awesome and untried
weapon.
Aerospace
War - It
was only when Canadian First Army
overran the V-1 buzz-bomb sites that
London and the
southeast of England saw the last one
land. By then
nearly 10,000 launchings of the
sub-sonic pilotless
"cruise missile" had inflicted 25,000
dead and
wounded civilian casualties. Then on the
8th the first
supersonic V-2 rocket hit London in a
deadly campaign that lasted
for over six months, and against which
there was no
defence.
NOVEMBER
1944
United
States - Franklin D.
Roosevelt was
re-elected
President
for an unprecedented fourth time. Harry
S
Truman joins him as Vice President.
DECEMBER
1944
Greece
-
Disagreements with the Greek communist
movement EAM/ELAS
over the future government of the
country led to fighting
and the declaration of martial law. By
month's end the
fighting startED to die down as
proposals for the
setting-up of a regency were announced.
The troubles were
not over until February 1945, and
trouble flareD again
with the outbreak of civil war in 1946.
1945
FEBRUARY
1945
Yalta
Conference -
For a week early in the month, Prime
Minister Churchill,
President Roosevelt and Generalissimo
Stalin met at Yalta in the Crimea. With
the Russians
advancing through Eastern Europe and
agreement on the
future frontiers of Poland and the
division of Germany
into four occupation zones, the shape of
much of post-war Europe
was determined. Stalin
agreeD to declare war on Japan once the
war in the west
was over.
MARCH
1945
Aerospace
War - As
the V-weapon
attack on Antwerp
continued, the last V-2 landed on London
on the 27th, by
which time 1,000 rockets had killed and
wounded nearly
10,000 people in southeast England.
APRIL
1945
United
States - Franklin Roosevelt died
in America on the 12th and
Vice President Truman was sworn in as
President of the
United States. Britain and especially
Winston Churchill
lost a great friend who did so much to
bolster the
country at a time when the British
Empire stood alone and
many Americans were staunchly
isolationist. Harry Truman
was
soon faced
with the decision
whether or not to use the A-bomb.
International
Conference
- Starting towards the end of
the
month, San Francisco hosted an
international conference
to draw up the constitution of the
United Nations
Organisation. 50 countries signed the UN
Charter on 26 June.
Western
Front - In
their advance, the Allies over-ran
Belsen, Buchenwald and
Dachau revealing to the world the full
horror of the Nazi
regime. The Russians had also captured
concentration camps in the east.
End of the
German
Surface Fleet - When Germany
surrendered, only three
cruisers survived. Of these "Prinz
Eugen" was
used in A-bomb trials in the Pacific and
"Leipzig"
scuttled in the North Sea in 1946 loaded
with poison gas
munitions.
Italy
-
Throughout the campaign Italian
partisans had waged a
bloody war behind German lines. Near
Lake Como on the
28th, Benito
Mussolini and his
mistress were captured and executed.
Germany -
As the
month drew to a close, Heinrich Himmler
tried to surrender to Britain and
the United States through Swedish
intermediaries, but
anything short of unconditional
surrender was refused. On
the 29th in his Berlin bunker, Adolf
Hitler married Eva Braun and nominated
Grand-Adm Karl
Doenitz as his
successor. Next day Hitler and his wife
committed suicide
and Doenitz became Fuehrer on 1st May.
JULY
1945
Atomic
Bomb - The
world's first A-bomb was successfully
exploded at
Alamogordo, New Mexico on the 16th July
in Operation
'Trinity'.
Potsdam
Conference -
In the second half of the month, the
heads of the three
great powers met at Potsdam outside
Berlin to continue
discussing the future of Europe and
final defeat of Japan. By the end of
the conference only Stalin remained of
the original three
major Allied leaders who had met in the
past. Accompanied
by President Truman of the United States
for the first
time, Winston Churchill was only there
at the start. On
the 26th the Potsdam Declaration was
broadcast, demanding
the unconditional surrender of Japan.
British
Politics
- Winston
Churchill's
Conservative Party was swept from power
and the Labour
Party under Clement Attlee took over the
reins of the wartime
Coalition Government. The new Prime
Minister travelled to
Potsdam for the rest of the conference.
Australia
- Prime
Minister John Curtin failed to see the
end of the war, dying on
the 5th after an illness. Acting PM,
Joseph Chiffley,
succeeded him.
AUGUST
1945
6th -
B-29
Superfortress "Enola Gay", flying from
Tinian
dropped the first atomic bomb on
Hiroshima.
The equivalent of 20,000 tons of TNT
killed 80,000
people.
9th -
The second A-bomb
was detonated
over Nagasaki and over 40,000 people
died.
