Battle of the Beams

RV Jones, Knickebein, X-Gerät > .
The Battle of the Beams was a period early in WW2 when bombers of the German Air Force (Luftwaffe) used a number of increasingly accurate systems of radio navigation for night bombing in the United Kingdom. British scientific intelligence at the Air Ministry fought back with a variety of their own increasingly effective means, involving jamming and distortion of the radio waves. The period ended when the Wehrmacht moved their forces to the East in May 1941, in preparation for the attack on the Soviet Union.

Prior to the war, Lufthansa and the German aircraft industry invested heavily in the development of commercial aviation, and systems and methods that would improve safety and reliability. Considerable effort went into blind landing aids which allowed aircraft to approach an airport at night or in bad weather. The primary system developed for this role was the Lorenz system, developed by Johannes Plendl, which was in the process of being widely deployed on large civilian and military aircraft.

In WW2, the Lorenz beam principle was used by the German Luftwaffe as the basis of a number of blind bombing aids, notably Knickebein ('crooked leg') and the X-Gerät ('X-Apparatus'), in their bombing offensive against English cities during the winter of 1940/41. Knickebein was very similar to LFF, modifying it only slightly to be more highly directional and work over much longer distance. Using the same frequencies allowed their bombers to use the already-installed LFF receivers, although a second receiver was needed in order to pinpoint a single location.

The X-Gerät involved cross-beams of the same characteristics but on different frequencies, which would both enable the pilot to calculate his speed (from the elapsed time between crossing the Fore Cross Signal and crossing the Main Cross Signal), and indicate when he should drop his payload. The calculation was performed by a mechanical computer. Lorenz modified this system to create the Viktoria/Hawaii lateral guidance system for the V-2 rocket.

When the British discovered the existence of the 'Knickebein' system, they rapidly jammed it, however, the 'X-Gerät' was not successfully jammed until later. A later innovation by the Germans was the 'Baedeker' or 'Taub' modification, which used supersonic modulation. This was so quickly jammed that the Germans practically gave up on the use of beam-bombing systems, with the exception of the 'FuGe 25A', which operated for a short time towards the end of Operation Steinbock, known as the "Baby Blitz".

A further operational drawback of the system was that bombers had to follow a fixed course between the beam transmitter station and the target; once the beam had been detected, defensive measures were made more effective by knowledge of the course.

The Black Chamber (1919–1929), also known as the Cipher Bureau, was the United States' first peacetime cryptanalytic organization, and a forerunner of the National Security Agency. The only prior codes and cypher organizations maintained by the US government had been some intermittent, and always abandoned, attempts by Armed Forces branches prior to WW1.

Herbert Osborn Yardley (April 13, 1889 – August 7, 1958) was an American cryptologist. He founded and led the cryptographic organization the Black Chamber. Under Yardley, the cryptanalysts of The American Black Chamber broke Japanese diplomatic codes and were able to furnish American negotiators with significant information during the Washington Naval Conference of 1921-1922. Recipient of the Distinguished Service Medal. He wrote The American Black Chamber (1931) about his experiences there. He later helped the Nationalists in China (1938–1940) to break Japanese codes. Following his work in China, Yardley worked briefly for the Canadian government, helping it set up a cryptological section (Examination Unit) of the National Research Council of Canada from June to December 1941. Yardley was reportedly let go due to pressure either from the Secretary of War Henry L. Stimson or from the British.

In June 1917, Yardley became a 2nd lieutenant in the Signal Corps and head of the newly created eighth section of military intelligence, MI-8. One early case was the cryptogram discovered in the clothing of German spy Lothar Witzke after he was arrested at the Mexican border in 1918. The evidence linked Witzke to significant sabotage activity in the U.S.

Yardley proved to be a very good administrator and during the war the people of MI-8 performed well even if they did not have any spectacular successes. After the war, the American Army and the State department decided to jointly fund MI-8 and Yardley continued as head of the "Cipher Bureau". They located their operations in New York City for legal reasons.

Cracking Japanese codes was a priority. David Kahn states:
The most important target was Japan. Its belligerence toward China jeopardized America's Open Door policy. Its emigrants exacerbated American racism. Its naval growth menaced American power in the western Pacific. Its commercial expansion threatened American dominance of Far Eastern markets.
After almost a year, Yardley and his staff finally managed to break the Japanese codes and were still reading Japanese diplomatic traffic when Washington hosted the Washington Naval Conference in 1921. The information the Cipher Bureau provided the American delegation regarding the Japanese government's absolute minimum acceptable battleship requirements was instrumental in getting the Japanese side to agree to a 5:3 ratio instead of the 10:7 ratio the Japanese Navy really wanted. This allowed Japan only 18 battleships to 30 for the U.S. and 30 for Great Britain instead of the 21 battleships Japan desired. This was the height of Yardley's cryptanalytic career.

In February 1941, a group of Americans arrived at Bletchley Park, in what marked the beginnings of an extraordinary UK-USA intelligence alliance that continues to this day (video series commemorates the 80th anniversary of this alliance). Bletchley Park’s Research Historian, Dr David Kenyon and the National Security Agency’s senior historian, David Hatch, explore the tentative first steps taken by the UK and USA in February 1941 to begin sharing their codebreaking secrets. Kenyon and Hatch explore how this relationship developed during 1941 in the months before America formally entered World War Two.

Military deception (MILDEC) is an attempt by a military unit to gain an advantage during warfare by misleading adversary decision makers into taking actions detrimental to the adversary. This is usually achieved by creating or amplifying an artificial fog of war via psychological operations, information warfare, visual deception, or other methods. As a form of disinformation, it overlaps with psychological warfare. Military deception is also closely connected to operations security (OPSEC) in that OPSEC attempts to conceal from the adversary critical information about an organization's capabilities, activities, limitations, and intentions, or provide a plausible alternate explanation for the details the adversary can observe, while deception reveals false information in an effort to mislead the adversary.

Deception in warfare dates back to early history. The Art of War, an ancient Chinese military treatise, emphasizes the importance of deception as a way for outnumbered forces to defeat larger adversaries. Examples of deception in warfare can be found in Ancient EgyptGreece, and Rome, the Medieval Age, the Renaissance, and the European Colonial Era. Deception was employed during World War I and came into even greater prominence during World War II.In modern times, the militaries of several nations have evolved deception tactics, techniques and procedures into fully fledged doctrine.

2. Operation Eiche
3. Operation Gunnerside
4. Operation Greif
5. Operation Fortitude South

Operation Bodyguard: Operation Fortitude North; Operation Fortitude South including Operation Quicksilver I-IV;

Operation Bodyguard was the code name for a World War II deception plan employed by the Allied states before the 1944 invasion of northwest Europe. The plan was intended to mislead the German high command as to the time and place of the invasion. The plan contained several operations, and culminated in the tactical surprise over the Germans during the Normandy landings on 6 June 1944 (D-Day) and delayed German reinforcements to the region for some time afterwards.

German coastal defences were stretched thin in 1944, as they prepared to defend all of the coast of northwest Europe. The Allies had already employed deception operations against the Germans, aided by the capture of all of the German agents in the United Kingdom and the systematic decryption of German Enigma communications. Once Normandy had been chosen as the site of the invasion, it was decided to attempt to deceive the Germans into thinking it was a diversion and that the true invasion was to be elsewhere.

Planning for Bodyguard started in 1943 under the auspices of the London Controlling Section (LCS). A draft strategy, referred to as Plan Jael, was presented to Allied High Command at the Tehran Conference in late November and approved on 6 December. The objective of this plan was to lead the Germans to believe that the invasion of northwest Europe would come later than was planned and to expect attacks elsewhere, including the Pas-de-Calais, the Balkans, southern France, Norway and Soviet attacks in Bulgaria and northern Norway.

Operation Fortitude was the code name for a World War II military deception employed by the Allied nations as part of an overall deception strategy (code named Bodyguard) during the build-up to the 1944 Normandy landings. Fortitude was divided into two sub-plans, North and South, with the aim of misleading the German High Command as to the location of the invasion.

Both Fortitude plans involved the creation of phantom field armies (based in Edinburgh and the south of England) which threatened Norway (Fortitude North) and Pas de Calais (Fortitude South). The operation was intended to divert Axis attention away from Normandy and, after the invasion on 6 June 1944, to delay reinforcement by convincing the Germans that the landings were purely a diversionary attack.

Operation Quicksilver was a military deception operation performed during the Second World War. Undertaken by the Allies in 1944, the operation threatened an invasion of France in the Pas de Calais region through the simulation of a large Field Army in South East England. Quicksilver formed part of the Operation Fortitude deception, itself part of the strategic Operation Bodyguard plan. The key element of Quicksilver was to convince the German that "First United States Army Group" (FUSAG) commanded by General George Patton would land in the Pas-de-Calais for the major invasion of Europe, after the landings in Normandy had lured the German defenders to that front. (FUSAG was a genuine army group headquarters which later became Omar Bradley's 12th Army Group, but was given a fictitious role and many non-existent divisions for purposes of deception.)

Juan Pujol García, known by the British code name Garbo and the German code name Arabel, was a double agent loyal to the Allies who played a crucial role in the deception by supplying Germany with detailed information from a network of non-existent sub-agents supporting the idea that the main invasion was to be in the Pas-de-Calais.

Quicksilver was subdivided into six subplans numbered I through VI:
  • Quicksilver I was the basic "story" for Fortitude: the First United States Army Group, based in the southeast of England, was to land in Pas-de-Calais after German reserves were committed to Normandy.
  • Quicksilver II was the radio deception plan of Quicksilver, involving the apparent movement of units from their true locations to southeastern England.
  • Quicksilver III was the display of dummy landing craft, including associated simulated wireless traffic and signing of roads and special areas. The landing craft, built from wood and canvas and nicknamed Bigbob's, suffered from being too light. Wind and rain flipped many over or ran them to ground.
  • Quicksilver IV was the air plan for Quicksilver, including bombing of the Pas-de-Calais beach area and tactical railway bombing immediately before D-Day.
  • Quicksilver V was increased activity around Dover (giving impression of extra tunneling, additional wireless stations), to suggest embarkation preparations.[12]
  • Quicksilver VI was night lighting to simulate activity at night where dummy landing craft were situated.
Operation Bodyguard succeeded and the Normandy landings took the Germans by surprise. The subsequent deception suggesting that the Normandy landings were a diversion led Hitler to delay sending reinforcements from the Pas-de-Calais region for nearly seven weeks (the original plan had specified 14 days).
