Germany used uncounted codenames in the second world war. Perhaps the most
famous of these names are "Fall Weiß" (Case White), the campaign
against Poland and "Seelöwe" (Sealion), the planned invasion of England.
The following table gives a small overview over the most important Codenames.
The list will be extended at need or when information becomes available.
Fall Rot (Case Red)
In 1935 the Fall Rot was a study to defend against a surprise attack
by France while defending the borders against Czechoslovakia and Poland.
The 37 version of Fall Rot included offensive operations against
Czechoslovakia with the aim of preventing a prolonged two-front war.
In 1940 it was the second part of the western campaign - after the
destruction of the BEF and the northern army of France it was, together
with Fall Braun, the attack on the rest of the French army which was
still entrenched in the Maginot line.
Fall Blau (Case Blue)
In 1938 a study from the Luftwaffe about aerial warfare against England.
This would later become the "Planstudie 1939", a concept for the whole
of aerial warfare.
In 1942 "Fall Blau" was the codename for the operations of Army Group South
with the operational targets: Woronesh, Stalingrad, and Baku.
Fall Weiß (Case White)
The campaign against Poland.
Fall Grün (Case Green)
In 1937 the plan to attack and occupy Czechoslovakia. Executed
without resistance in May 1938, after the Munich conference.
In 1940 the plan for a frontal attack on the Maginot line. Later
renamed Fall Braun.
Fall Gelb (Case Yellow)
The western campaign of 1940. Included the attack on Luxembourg, the Netherlands
and Belgium. Originally planned as a frontal attack in coordination with Fall Braun,
it was later modified into a armored attack through the Ardennes using a scheme
developed by General von Manstein.
Fall Braun (Case Brown)
Plan to attack with Army Group C on the western front in June 1940 (see Fall Grün)
to relieve Army Group A and B, if necessary.
Heeresgruppe C (von Leeb) was the army to execute this plan. Actually,
in 1940 the Heeresgruppe C was far too weak to do anything but hold their position
(some 19 divisions, most of them second class, for the whole southern front,
including the Swiss border, against 37 French divisions and the Maginot line -
some of their best among them). When Army Group C finally attacked for real, they
were unexpectedly successful since the French no longer expected offensive action
The occupation of Denmark and Norway, 9.4. - 10.6.1940.
Planned operation for a 1940 naval invasion of England. Main landing
area was the coast from Beachy Head to Dover, with side operations at
Brighton and Exeter.
Adlertag (Eagles day)
Start of the planned air battle to win command of the skies.
Adlertag was August the 8th 1940. In an epic battle the British fighter-pilots
managed to inflict heavy losses on the ill-equipped German bombers. Sealion was
postponed, the battle of Britain would not happen - for the British, this battle
was already won.
Artus-Plan / Kathleen
A planned invasion in Summer 40 of Ireland with the support of the IRA.
Preparatory work on this plan was made by the IRA themselves.

The occupation of Greece.
The air assault on Crete. This would only be executed in the case of an
easy success of Marita.
The losses for the Germans in this operation exceeded those of the whole
The planned invasion of Malta in 42. The operation was mainly canceled due
to lack of oil for the Italian warships.
Order 21 from December 18th 1940. The attack on Russia. Preparations
would be concluded by May 15, 1941. The attack started on June 21, 1941.
The attack was postponed for a month due to several factors, the most
important were the ongoing operations in the Balkans. The attack failed
finally in the snowfields before Moscow.
The battle for Moscow. The original goal was a kettle (envelopement) to
destroy the army group Timoschenko, then a second, deeper, kettle with Moscow
in it. The attack started on the 2.10.41.
Attack on the Russian front at Kursk in 43.
This attack would become the largest tank battle in history. The attack was
postponed several times by Hitler himself to allow the inclusion of new armor
designs. This gave the Soviets the chance to prepare a stout defense and a
counterattack. After this battle Germany never again gained the initiative.
Herbstnebel / Wacht am Rhein (Autumn Fog / Watch on the Rhine)
Codename for parts of the offensive in the Ardennes, 1944.
Part of the deception for this offensive was the secret operation
"Heinrich", in which the foreign worker contingents of the Axis were
infiltrated by German agents. They would disguise as members of the
resistance movement and hire their fellows for anti-German activities.
Fed with important (but wrong) information about the German military, the
workers where given a chance to escape by their resistance-comrades.
The information about the German troops acquired in this way was considered
reliable by the Allied, enabling the Germans a last tactical surprise.
Kriegsmarine and Luftwaffe Codenames
Paukenschlag (Beat of the kettledrum)
A collective name for the first coordinated operations of German submarines
on the US east coast.
Lack of a convoy system along the coasts of the United States made for a
lot of fat targets for German submariners. Later operations had nice names
like "Mordbrenner" or "Reißewolf". The diary of radio operator Wolfgang
Hirschfeld gives a first hand account of the German side.
Since early 41 the central organization for the German nightfighters using the
radars Freya and Würzburg.
Operational zones for German nightfighters from Denmark to southern France.
The name for a "secret weapon" of the German nightfighters Several
machineguns would shoot upward at an angle of 80°, to take advantage of the
the weak underside of the British bombers. Originally this weapon was
developed by private initiative.
Wilde Sau (Wild Sow)
A codename for the usage of single-engine fighters at night. These
would fly without any radar, the pilot relying on eyesight.
Although successful in a few cases, the main problem for these
fighters was to be over the right city at the correct time, something that
never was really solved. Generally the idea was considered a failure.
Alpenfestung (alp fortress)
A supposed mighty fortress in the German alps. The German variant
of the Alpenfestung was actual inspired by rumors from the Allied
side. Only minimal works were even started when the war ended.
Wolfsschanze (wolves entrechment)
The most used of many (at least 11) -Führer-HQs, near Rastenburg (East Prussia).
The walls and ceiling of Hitler’s bunker had a strength of 7 meters.
Aufbau Ost (eastern build up)
1.8.40. The secret buildup of the infrastructure in the Generalgouvernement
(the occupied part of Poland) to support Operation Barbarossa.
Study for the preparation of bacteriological warfare. 23.2.43
In August 43 some 40 soothsayers, fortune-tellers, astrologers and
similar occupations were collected (from prison and KZs) on order from Himmler
to divine the whereabouts of the captured Mussolini.
